Description

Technology Field

[0001] The present invention relates to a broadcasting and disaster management system including a remote management module and telephone broadcasting in an LTE integrated wireless communication system. More specifically, the invention addresses the issue where, when units such as frequency combiners and distributors in a wireless communication system configured for general use are applied and operated for the purpose of national infrastructure projects requiring high safety and security, their utility is restricted; and when units constituting the wireless communication system are applied and operated for national infrastructure projects requiring special safety and security, specialized frequency bands distinct from general-use systems must be applied, and there is a problem that frequency combiners, Wi-Fi combiners, and distributors must be redesigned to implement system operation using these frequencies. Therefore, the invention enables frequency combiners, Wi-Fi combiners, and distributors suitable for specific fields and purposes to operate in frequency bands specialized for the project, allows for selective operation to link with 5G frequencies for public services, and enables radio broadcasting in large-scale industrial sites such as plants and nuclear power plants. Background Technology

[0003] A page phone is a device that broadcasts through a speaker and is used as a means of communication to transmit instructions to people working in large-scale factories, power plants, ships, construction sites, etc., which are dispersed across various regions.

[0004] When such page phones are installed in actual field locations, a very large number of page phones are installed. By using these page phones to set priorities in accordance with regulations and enabling users to listen to emergency broadcasts (fire broadcasts, civil defense broadcasts, telephone broadcasts using internal telephones, public address broadcasts) through the handset and command speaker of the page phone (IP Phone), separate public address broadcasting equipment is unnecessary, thereby saving costs and maximizing the usability of the equipment.

[0005] In addition, the above page phones are operated by connecting cables in parallel, but in the event of a failure caused by cable disconnection or noise, it was not easy to accurately locate the fault point due to the complex cable connections.

[0007] Figure 1 is a configuration diagram of a conventional page phone system.

[0008] As illustrated in FIG. 1, a conventional paging phone system includes a central management unit (10) that centrally manages the status of a plurality of line test units (31, 32) and a plurality of paging phones (40-1, ..., 40-n) (40-n+1, ​​..., 40-n+N), a multi-repeater (20) that converts RS-232 communication of a communication line (L1) and RS-485 communication of a communication line (L2) between the central management unit (10) and the line test units (31, 32), a plurality of line test units (31, 32) that perform the function of connecting the plurality of paging phones and a plurality of analog lines (n) of the paging phones, and a plurality of analog type paging phones (40-1, ..., 40-n) (40-n+1, ​​..., 40-n+N) connected to the lines (n).

[0009] Here, the configuration of the desktop pagination phone (50) is the same as that of multiple pagination phones (40-1,...,40-n)(40-n+1,...,40-n+N), except that the desktop version is installed in an office where the broadcast volume does not need to be low.

[0010] In a conventional paging phone system configured as described above, when a command button is pressed on any paging phone and a command broadcast is made through the handset, an analog signal processed voice signal is transmitted through the line (n).

[0011] The voice signal transmitted from any of the above-mentioned pagination phones is transmitted to all other pagination phones through line (n), or line (n) and line test section (31, 32), and all of the above-mentioned pagination phones receive this voice signal and output it to a speaker through an internal amplification circuit.

[0012] In addition, after calling any recipient through the above command broadcast, the page phone presses the call channel button (e.g., one of five) and broadcasts the command.

[0013] Conventional paging phone systems operating in this manner have a distance limitation (e.g., within 2 km) because the paging phone is of the analog type and the paging phone equipment and line from the handset are all analog voice signals.

[0014] In addition, since an analog type is used, a cable quantity (19 lines) is required for all necessary signals, namely command signal 2 channels (2 pairs - 4 lines), call signal 5 channels (5 pairs - 10 lines), control signal 1 channel (1 pair - 2 lines), and power line (3 lines), so there are problems such as high construction costs and complex installation.

[0015] On the other hand, analog type page phones are composed of numerous analog components such as transformers, op-amps, and relays, which leads to the problem of increased volume and weight.

[0016] And conventional page phone systems use an analog method, which results in high power loss and limits to the output of the power amplifier.

[0017] Furthermore, the coaxial method was vulnerable to natural disasters, required a long time to restore in the event of loss or failure, and resulted in high costs due to the difficulty and complexity of long-distance deployment. In particular, during long-distance deployments, distortion occurred due to impedance and signal delay caused by the cable material, and there were issues with cable degradation over time.

[0018] In addition, there is a problem that if discarded wired cables buried underground are left unattended, it can cause environmental issues.

[0019] Recently, a Public Safety LTE network (PS-LTE network) is being constructed based on LTE to provide communication services to users related to public safety, such as police officers, firefighters, military personnel, coast guard officers, emergency medical staff, and local governments. PS-LTE stands for National Disaster and Safety Communication Network.

[0020] In other words, it is a disaster safety wireless communication network that provides existing PTT voice services and video / data services together on a single packet-based LTE network, using a PS-LTE wireless communication network suitable for disaster-related agencies as a disaster response wireless communication technology on LTE, the 4th generation mobile communication standard, for rapid and efficient national-level disaster management in the event of a major disaster such as a fire, flood, earthquake, or tsunami.

[0021] This PS-LTE network resolves the issue of inter-departmental communication failures in existing public safety networks due to differing frequencies and technologies. It is a disaster safety wireless communication network that combines existing PTT voice services with video and data services over a single packet-based LTE network.

[0022] The PS-LTE network has been built since 2014, and as of early 2018, limited service is being provided to some areas of Korea. In particular, with the recent PyeongChang Olympics, base stations have been installed in areas such as PyeongChang, Gangneung, and Jeongseon, and service is being operated on a trial basis.

[0024] FIG. 2 is a diagram showing an embodiment of a broadcasting system used in a broadcasting and disaster management system including a remote management module and telephone broadcasting in an LTE integrated wireless communication system according to the prior art, and FIG. 3 is a diagram showing an embodiment of a broadcasting equipment (PA) in the broadcasting system shown in FIG. 2.

[0025] A broadcasting system used in a broadcasting and disaster management system including a remote management module and telephone broadcasting in an LTE integrated wireless communication system according to the prior art is as shown in FIG. 2. In a broadcasting system dedicated to railway PA broadcasting, the security building, the main control building, and the general office building are configured with a main control panel (1000) in the security building, the main control building is configured with a main control panel (1010), a broadcasting management room (1200), a remote broadcasting connection unit (1300), a telephone connection unit (1400) with built-in SIP, station broadcasting equipment (0A) (1500), and a speaker section (1610, 1620, 1630) consisting of multiple speakers, and the general office building is configured with a main control panel (1020), a remote broadcasting connection unit (1310), a telephone connection unit (1410) with built-in SIP, station broadcasting equipment (PA: Public Address System)) (1510), and a speaker section (1640, 1650, 1660) consisting of multiple speakers. At this time, it shows the security building, the main control building, and the general office building communicating through the IP network (1100).

[0026] And the historical broadcasting equipment (1500) is composed of a switching matrix (1501), a plurality of speaker amplifiers (1502) which are network amplifiers, and a plurality of speaker selection relays (1503), as shown in FIG. 3.

[0027] This broadcasting system is configured to allow broadcasting by designating individual speaker channels within each Zone (district) and Zone from arbitrary main control panels (Call Stations) (Remote AMPs) (1000, 1010, 1020), and to enable priority setting between main control panels (Call Stations). In addition, remote PC broadcasting (TTS broadcasting) is enabled.

[0028] Meanwhile, the main control panel (Call Station) is configured as a desktop type, and the call server is designed to control the main control panel (Call Station) and enable the operation of N connections to the main control panels (Call Station). Additionally, the telephone connection unit allows for Relay Group selection (individual call differentiation: by channel) and Relay Group F / W modification (adding Device ID).

[0029] Meanwhile, call operations on the main control panel allow for individual calls (by channel) and group call zones, and all calls are made available during control broadcasts.

[0031] However, in these conventional technologies, when applying and operating a unit that constitutes a wireless communication system for a national infrastructure project requiring special safety and security, a specialized special frequency band distinct from a general-purpose system must be applied. Since there is no technical configuration for this, it is necessary to develop a system that enables the operation of frequency combiners, Wi-Fi combiners, and distributors for special purposes in a frequency band specialized for the project, and allows for selective operation so that they can also be linked to 5G frequencies for public services.

Effects of the invention

[0040] According to the present invention, the following effects are achieved.

[0041] First, when applying and operating a unit that constitutes a wireless communication system for a national infrastructure project requiring special safety and security, a specialized special frequency band distinct from a general-purpose system must be applied.

Specific details for implementing the invention

[0045] A preferred embodiment of the present invention will be described in detail with reference to the attached drawings as follows.

[0046] Furthermore, while the terms used in this invention have been selected to be as widely used as possible, there are also terms arbitrarily chosen by the applicant in specific cases. Since the meanings of these terms are described in detail in the relevant description of the invention, it should be noted that the invention should be understood based on the meaning of the terms rather than their mere names. Additionally, in describing the embodiments, explanations regarding technical content that is well known in the technical field to which this invention belongs and is not directly related to this invention are omitted. This is intended to convey the essence of the invention more clearly without obscuring it by omitting unnecessary explanations.

[0048] When companies use various functions for services specialized for corporate purposes, in addition to general public services, there are limitations to the use of 5G frequencies for public services. To overcome this, a Closed Network (Private Network) suitable for corporate purposes is required, and a separate, independent 5G frequency distinct from 5G for public services is required on this Private Network.

[0049] In the case of broadcasting and call systems within a wireless communication system integrated with WiFi and LTE, there are advantages such as the ability to broadcast and issue commands using WiFi and LTE between the terminals of workers connected to the integrated antenna of the high-speed wireless communication system and IP phones connected to IP BAX at a remote location, and the ability to broadcast from each IP phone to all IP phones by inserting a broadcasting function into the special function keys of the IP phones. However, when connecting to and using a 5G Open Network for public services to provide services specialized for corporate purposes, it was not possible to utilize such specialized services. Furthermore, since hacking or other forms of access could be easy to exploit regarding the security of companies conducting national infrastructure projects requiring high levels of safety and security, it could pose serious security problems regarding the safety of facilities, making it difficult to apply services that meet corporate purposes. Additionally, it could be uneconomical because public service network usage fees had to be paid.

[0050] In other words, due to the trend of advancement in the Fourth Industrial Revolution, the utilization of data by each company is increasing exponentially.

[0051] In other words, these include the expansion of comprehensive management data required for business operations, remote management through remote control of safety equipment, the necessity of non-contact preventive maintenance of safety equipment leveraging metaverse network services, the universalization of video data utilization from still images to action images, and the management of safety equipment through robot control.

[0052] Therefore, it is essential to build a high-level Data Network (5G) within companies in accordance with the advancement of industry, and especially in the case of national infrastructure projects requiring high safety and security, a wireless communication system that operates by applying 5G frequencies specialized for the purpose of infrastructure projects is indispensable.

[0053] Therefore, in order for companies and other entities to use various functions for services specialized for corporate purposes, it is necessary to configure a Closed Network (Private Network) suitable for this purpose and to configure a wireless communication system by applying a separate, independent 5G frequency band of 4.72 GHz to 4.82 GHz, which is distinct from 5G for public services, on this Private Network.

[0055] FIG. 4 is a diagram showing an embodiment of a frequency band compatibility system with a frequency combiner of a Wi-Fi and LTE integrated wireless communication system used in the present invention.

[0056] An embodiment of the frequency band compatibility system with a frequency combiner for a Wi-Fi and LTE integrated wireless communication system according to the present invention is shown in FIG. 4, which is composed of an IPBAX (100) which is a page phone main unit, a plurality of first to nth IP phones (101, 102, 103, 104), PS-LTE (200), a base station (300), a high-power combiner (400), a wireless backhaul device (410), a Wi-Fi combiner (500), an integrated control room (600), a plurality of distributors (710, 720, 730), and a plurality of integrated antennas (810, 820, 830, 840).

[0057] Here, the IPBAX (100) is a terminal device for making calls, which is a device that holds the handset and presses the command button to call the other party verbally through multiple IP phones (101, 102, 103, 104) and presses the call button to make a call to each other. This IPBAX (100) is electrically connected to multiple other IP phones (101, 102, 103, 104).

[0058] The IPBAX (100) supports communication between multiple IP phones (101, 102, 103, 104) and multiple workers' wireless communication terminals, such as walkie-talkies (910, 911), smartphones (920, 921), and smart helmets (930, 931), which are connected to multiple integrated antennas (810, 820, 830, 840) described below. Additionally, the IPBAX (100) supports broadcasting to other IP phones (101, 102, 103, 104) through a broadcasting function inserted into one of the special function keys of the IP phones (101, 102, 103, 104) among the multiple IP phones (101, 102, 103, 104).

[0059] PS-LTE (200) is an LTE-based national disaster safety wireless communication network. This PS-LTE (200) is a wireless communication network suitable for disaster-related agencies for rapid and efficient national-level disaster management in the event of a major disaster such as a fire, flood, earthquake, or tsunami. It is a disaster safety wireless communication network that combines disaster response wireless communication technology with LTE, a 4th generation mobile communication standard, and provides existing PTT voice services and video / data services together in a single packet-based LTE network (survival, reliability, disaster response, security, operation, efficiency).

[0060] For reference, LTE (Long Term Evolution) is a fourth-generation (4G) wireless communication technology developed by the 3GPP consortium. However, as fifth-generation (5G) mobile communication technology is becoming increasingly widespread, support for it is also necessary, and in addition, Wi-Fi technology needs to be incorporated.

[0061] LTE refers to the field of wireless technology. According to standardization terminology, the wireless access technology referring to the air interface is E-UTRA (Evolved Universal Terrestrial Radio Access), the wireless network including wireless network nodes and wireless access technology is E-UTRAN (Evolved Universal Terrestrial Radio Access Network), and the core network symmetrical to the wireless network is EPC (Enhanced Packet Core). The entire system composed of EPC and E-UTRAN is called EPS (Enhanced Packet System).

[0062] Meanwhile, in the present invention, SIP (Session Initiation Protocol) is embedded in the PS-LTE (200). Here, SIP is a VoIP-related standard and is the IETF signaling protocol (IETF SIP) corresponding to ITU-T H.323. Compared to H.323, it is very simple and has the characteristic of simple call setup.

[0063] While H.323 was a standard for communication with past internet phones, that is, IP phones (101, 102, 103, 104), the present invention supports communication via SIP between IPBAX (100) and PS-LTE (200), thereby supporting communication via SIP when communicating with IP phones (101, 102, 103, 104). This SIP has the advantage of being easy to parse and compile, making it easy to extend and implement.

[0064] The base station (300) separates the digital signal processing unit and the radio signal processing unit, which were integrated into the base station, into a digital unit (hereinafter referred to as DU) and a radio unit (hereinafter referred to as RU), respectively. The RU processes downlink frequencies of 773 to 783 MHz and uplink frequencies of 718 to 728 MHz.

[0065] The high-power combiner (400) is a frequency combiner that services frequencies in the LTE (4G) band (700 MHz) and the 5G band (3.5 GHz). In general, in systems using radio frequency (RF), combiners with a structure that connects various types of input signals to transmit them as a single signal are widely used. Variables that determine the inherent characteristics of such power combiners / dividers include excellent isolation characteristics between each output port (or between input ports), and the RF signal magnitude between each output port must be 1 / N times (in the case of a divider) or N times combined (in the case of a combiner). Additionally, in the case of a divider, the phase between each port must match. In particular, combiners and dividers have various uses in applications utilizing RF amplifiers.

[0066] In addition, the high-power combiner (400) forms a Closed Network (Private Network), and applies a 4.72 GHz to 4.82 GHz band as a separate, independent dedicated 5G frequency distinct from 5G for public services on this Private Network. This is intended for the expansion of comprehensive management data required for corporate operations, remote management through remote control of safety equipment, the necessity of non-contact preventive maintenance of safety equipment by riding on metaverse network services, the universalization of video data utilization from still images to action images, and safety equipment management through robot control. By building a high-level Data Network (5G) within the company that corresponds to the advancement of industry, a wireless communication system is configured to operate by applying a dedicated 5G frequency band (4.72 GHz to 4.82 GHz band) specialized for the purpose of the national infrastructure business, which requires a high level of safety and security.

[0067] Meanwhile, a wireless backhaul device (410) is configured in the high-power combiner (400). Through the wireless backhaul device (410), wireless communication is supported with a private wireless communication system that applies the corporate-exclusive 5G frequency of another headquarters.

[0068] These wireless backhaul devices (410) can transmit and receive data without distortion of quality even when transmitting and receiving wireless communication data to each headquarters at a distance depending on the distance between each headquarters (see FIG. 7), and can improve the transmission and reception quality by adjusting the bandwidth, which can be adjusted according to field test, and the distance between each headquarters is configured to be 1 to 10 km, but there is no need to specifically limit it.

[0069] Wireless frequency resources are finite public goods allocated to reflect the policies and characteristics of each country. Currently, most wireless frequency resources in the microwave band have already been allocated, making it difficult to secure new resources. Therefore, considering new services requiring high-capacity data transmission in the future, wireless frequency resources in the millimeter wave band are inevitably the only viable option.

[0070] Considering the above situation, it is expected that the wireless frequency resources likely to be applied to the 5th generation wireless backhaul system will be the V band in the 57-66 GHz range and the E band in the 71-76 GHz and 81-86 GHz ranges. Therefore, it is desirable that the wireless backhaul device (20, 21) of the present invention also be operated with the V band in the 57-66 GHz range and the E band in the 71-76 GHz and 81-86 GHz ranges.

[0071] In the case of transmitting and receiving data between headquarters in a private network configured in each headquarters (e.g., A & B) of the same company, a dedicated network (Private Network) is established by installing a backhaul (Advanced millimeter-wave wireless bridge) in each wireless communication system or other private network communication system, rather than using a dedicated wired network built in the company or a public communication network operated by a telecommunications carrier as in the conventional method of FIG. 1 for transmitting and receiving data generated in each headquarters in a wireless manner.

[0072] When using such a wireless backhaul device (410), as the utilization of data by each company is exponentially amplified due to the trend of advancement of the 4th industrial revolution, it is necessary to support the expansion of comprehensive management data required for corporate operations, remote management through remote control of safety equipment, non-contact preventive maintenance of safety equipment by riding on metaverse network services, the universalization of video data utilization from still images to moving images, and safety equipment management through robot control. However, if a public network such as 5G / LTE / Wi-Fi used for public services is connected and used for services specialized for corporate purposes, the specialized services cannot be utilized efficiently. Furthermore, hacking and other forms of access are easy to exploit in the security of companies conducting national infrastructure projects that require high levels of safety and security, which poses serious security problems regarding the safety of facilities. In addition, it is difficult to discover and apply services that meet corporate purposes, and to solve the uneconomical problems caused by having to pay network usage fees for public services, data files transmitted and received from each headquarters located far apart within the company (plant, nuclear power plant, subway, train station, etc.) The operational inefficiency of using public networks can be overcome by establishing a system capable of transmission through wireless pipelines such as backhaul.

[0073] The Wi-Fi combiner (500) is a remote management module in the present invention, which combines frequencies of the LTE band (700 MHz) and the 5G band (3.5 GHz), as well as frequencies of the Wi-Fi bands of 2.4 GHz and 5 GHz, and is equipped with a LAN Port function. In addition, it is also possible to combine a dedicated 5G frequency band (4.72 GHz ~ 4.82 GHz band) specialized for infrastructure business purposes.

[0074] The integrated control room (600) basically receives the status of the Wi-Fi combiner (500) periodically from a board programmed to perform a status detection system for the Wi-Fi combiner (500), and if an abnormality occurs, it checks the status of the Wi-Fi combiner (500) or replaces it through an administrator.

[0095] The types of calls of this main control panel (1000) can be classified into ALL, Group, and individual calls, and the communication method is TCP / IP (between Call Station and Network AMP), and is connected wirelessly through the integrated antenna (800) of the wireless communication system and the Wi-Fi combiner (500) (2.4G / 5G).

At this time, Wi-Fi (2.4G / 5G) is used as the wireless connection frequency.

[0100] Additionally, the broadcasting control room (1200) is configured with a system connected via a Wi-Fi combiner (500) so that HD video (2M) data from an IP Camera (940) wirelessly communicated through an integrated antenna (800) is received by the video control server (1210) and monitor (1220) of the broadcasting control room (1200).

[0104] FIG. 7 is a diagram illustrating an embodiment of a wireless communication data transmission and reception system using backhaul in a broadcasting and disaster management system including a remote management module and telephone broadcasting in an LTE integrated wireless communication system according to the present invention.

[0105] An embodiment of a wireless communication data transmission and reception system using backhaul in a broadcasting and disaster management system including a remote management module and telephone broadcasting in an LTE integrated wireless communication system according to the present invention is shown in FIG. 7. Depending on the distance between the wireless backhaul devices (1410, 1420) between each headquarters in a different remote area equipped with a private wireless communication system and each headquarters in a different remote area equipped with a private wireless communication system, data transmission and reception can be performed without distortion of quality even when transmitting and receiving wireless communication data to each remote headquarters, and transmission and reception quality can be improved by adjusting the bandwidth, and can be adjusted according to field test. The distance between each headquarters is configured to be 1 to 10 km, but there is no need to specifically limit it.

[0106] Wireless frequency resources are finite public goods allocated to reflect the policies and characteristics of each country. Currently, most wireless frequency resources in the microwave band have already been allocated, making it difficult to secure new resources. Therefore, considering new services requiring high-capacity data transmission in the future, wireless frequency resources in the millimeter wave band are inevitably the only viable option.

[0107] Considering the above situation, it is expected that the wireless frequency resources likely to be applied to the 5th generation wireless backhaul system will be the V band in the 57-66 GHz range and the E band in the 71-76 GHz and 81-86 GHz ranges. Therefore, the wireless backhaul device (20, 21) of the present invention can also be operated with the V band in the 57-66 GHz range and the E band in the 71-76 GHz and 81-86 GHz ranges.

[0108] In this invention, when transmitting and receiving data generated from a private network configured in each headquarters (e.g., A & B) of the same company between headquarters, instead of using a wired-based private network built by the company or a public communication network operated by a telecommunications carrier as in the conventional method of FIG. 1, a backhaul (Advanced millimeter-wave wireless bridge) (20, 21) is installed in each headquarters or in a communication system based on other private networks, thereby establishing a private network that operates by applying the data generated from each headquarters to a long-distance transmission and reception system using a wireless method.

[0109] Here, the communication system established in each headquarters (A, B) is a private wireless communication system using a 5G frequency dedicated to the enterprise, and an embodiment thereof will be described with reference to Fig. 3, which will be described later.

[0110] As the utilization of data by each company is increasing exponentially due to the trend of advancement in the Fourth Industrial Revolution, this invention must support the expansion of comprehensive management data required for business operations, remote management through remote control of safety equipment, the necessity of non-contact preventive maintenance of safety equipment by leveraging metaverse network services, the universalization of video data utilization from still images to active images, and safety equipment management through robot control.

[0111] When connecting to and using public networks such as 5G / LTE / Wi-Fi 6 for public services to provide services specialized for corporate purposes, the specialized services cannot be utilized efficiently. Furthermore, since the security of companies conducting national infrastructure projects requiring high levels of safety and security is susceptible to hacking, it poses serious security problems regarding the safety of facilities. Additionally, it is difficult to discover and apply services that meet corporate objectives, and to resolve the uneconomical issues arising from the payment of public service network usage fees, the operational inefficiency of using public networks can be overcome by constructing a system that can transmit data files transmitted and received from each headquarters (10, 11) located far apart within the company through a wireless pipeline, such as a wireless communication data transmission and reception system like backhaul. When comparing this wireless communication data transmission and reception system with a conventional wired network as shown in Table 1 below,

[0112] item Wired configuration Wireless configuration (the present invention) Coaxial optical cable Influence of the external environment Vulnerable to natural disasters, and takes a long time to restore in the event of loss or defects. Unsuitable for long-distance installation It is minimally affected and can be easily restored in the shortest possible time even if affected. Long-distance construction costs High cost (difficult to implement, complex) Low cost (easy to implement, simple) quality When installing over long distances, distortion occurs due to impedance and signal delay caused by the cable material, and cable degradation occurs over time. No distortion (no cable degradation over time) Data transmission / reception capability Data transmission is limited due to narrow bandwidth, resulting in low transmission / reception quality. Easy data transmission with wide bandwidth (high transmission / reception quality) Maintenance safety Installation, relocation, expansion, and fault repair are complex and time-consuming. Installation by a specialized optical cable company Installation, relocation, expansion, and fault repair are simple Operability There are many limitations to applications for specific purposes (Network applications via software are not possible) Setting up and operating are difficult because optical converters and the like are used. Suitable for appropriate applications that meet the operator's objectives (remote network applications via software possible) Scalability Network operation is difficult due to compatibility with existing installed equipment, and additional costs are incurred. No scalability Network operation is easy due to compatibility with existing equipment, and additional costs are low. eco-friendly Causing environmental problems (illegible wired cables buried underground left unattended) Green environment (cable-free eco-friendly)
