[0059] In some embodiments, referring to FIG3 , the Halow signal filter module 210 includes a plurality of single-passband filters connected in parallel. For example, FIG3 shows a first single-passband filter 151 and a second single-passband filter 152 .

[0065] In some embodiments, the RF transmission path RF_TX is further provided with a power amplifier module PA for adjusting the power of the RF transmission signal, and the RF reception path RF_RX is further provided with a low noise amplifier module LNA for filtering the RF reception signal.

[0066] The Halow communication module of the present application can effectively solve the mutual interference problem when the Halow communication process works simultaneously with cellular communication, Wi-Fi communication and other networks; the present application solution also sets the Halow signal filter module that meets the communication requirements of multiple frequency bands of Halow signals on the same printed circuit board, so that the Halow communication module can adapt to multiple communication frequency bands while realizing the intensive utilization of hardware resources, thereby reducing the cost of the Halow communication module manufacturing and application process.

[0067] Some embodiments of the present application describe a mobile communication device.

[0068] Figure 5 is a schematic diagram of the components of a mobile communication device according to an embodiment of the present application. As shown in Figure 5, the mobile communication device 1000 includes a Halow communication module 100, an LTE communication module 300, a Wi-Fi communication module 400, and a communication control module 500. The Halow communication module 100 can be any of the Halow communication modules 100 provided in the preceding embodiments.

[0069] In some embodiments, the Halow communication module 100 includes a Halow base module 101 and a Halow antenna ANT.

[0070] The RF signal receiving and transmitting common end (TRX) of the Halow antenna ANT is provided with a RF filter 133, which is used to suppress the transmitter background noise of the Halow communication module 100, which is also called the ground noise. It is easy for those skilled in the art to understand that, based on the common knowledge of filters, the Halow signal filter module 210 may include the RF filter 133. The RF filter 133 includes, for example, a surface acoustic wave (SAW) filter, which may also be called a surface acoustic wave filter or a surface acoustic wave filter. During specific installation, the RF filter 133 is installed on the printed circuit board (PCB) where the Halow communication module is located, for example, by surface mount technology (SMT).

[0071] In some embodiments, the communication control module 500 is configured to select the communication mode of the mobile communication device 1000 based on the comparison results of the communication network parameters of the Halow communication module 100, the LTE communication module 300 and the Wi-Fi communication module 400 with the corresponding thresholds, and according to the set communication module selection priority.

[0072] The RF filter 133 is configured, for example, to suppress the transmitter noise floor of the Halow communication module 100 to a value less than or equal to a first noise threshold. The first noise threshold is, for example, less than or equal to -174 dBm / Hz (dBm / Hz represents 1 decibel milliwatt of power per hertz). -174 dBm / Hz is approximated by -173.98 dBm / Hz, so the value of the first noise threshold can be between -173.98 dBm / Hz and -174 dBm / Hz, or can also be -180 dBm / Hz or -190 dBm / Hz.

[0073] The communication frequency band of the Wi-Fi communication module 400 includes 2.4GHz, 5GHz and / or 6GHz (gigahertz). In the technical solution of the present application, the Wi-Fi communication module 400 supports 802.11b / g / n / ax communication standards (or communication protocols) in the 2.4GHz communication frequency band, the Wi-Fi communication module 400 supports 802.11a / n / ac / ax communication standards in the 5GHz communication frequency band, and the Wi-Fi communication module 400 supports 802.11be communication standards in the 6GHz communication frequency band. The aforementioned communication standards are formulated and promoted by the International Wi-Fi Alliance based on the IEEE 802.11 wireless communication network standard. The Wi-Fi communication module 400 includes a Wi-Fi antenna 401, which is connected to a wireless network access point (Wi-Fi Access Point, Wi-Fi AP) to achieve network communication.

[0074] The Halow communication module 100 operates in a sub-1 GHz frequency band. More specifically, in some embodiments, the Halow communication module 100 operates in a frequency band of 863-870 MHz and / or 902-931 MHz. The Halow communication module 100 supports the 802.11ah communication standard in the sub-1 GHz frequency band. The Halow communication module 100 connects to a Halow access point (Halow AP) via a Halow antenna ANT to implement wireless network communication.

[0075] In the present application, the LTE (Long Term Evolution) communication module 300 supports communication modes such as the third-generation (3G), fourth-generation (4G), and fifth-generation (5G) mobile communication standards. Specific communication modes include, for example, TD-LTE (TD-SCDMA LTE, Time Division Synchronous Code Division Multiple Access). The LTE communication module 300 includes an LTE antenna 301, which communicates with a remote base station for uplink and downlink communication, enabling network data transmission.

[0076] In some embodiments, the antenna isolation between the Halow antenna ANT and the LTE antenna 301 and the Wi-Fi antenna 401 is greater than or equal to a second antenna isolation threshold. The second antenna isolation threshold is 10 dB (decibel). The antenna isolation between the Halow antenna ANT and the LTE antenna 301 and the Wi-Fi antenna 401 is, for example, 10 dB, 20 dB, or 30 dB.

[0077] In some embodiments, selecting the communication mode of the mobile communication device 1000 according to the comparison results of the communication network parameters of the Halow communication module 100, the LTE communication module 300 and the Wi-Fi communication module 400 with the corresponding thresholds, and according to the set communication module selection priority, includes: selecting the communication mode of the mobile communication device 1000 according to the comparison results of the signal strength and data packet loss rate of the communication network of the Halow communication module 100, the LTE communication module 300 and the Wi-Fi communication module 400 with the corresponding thresholds, and according to the set communication module selection priority.

[0078] The set communication module selection priorities include, for example: the Wi-Fi communication module 400 is the first selection priority, the Halow communication module 100 is the second selection priority, and the LTE communication module 300 is the third selection priority.

[0079] The communication frequency band where the Halow communication module 100 is located has the characteristics of low power consumption and the ability to achieve long-distance signal transmission. At the same time, the communication frequency band where the Halow communication module 100 is located is relatively low compared with the Wi-Fi communication module 400 and the LTE communication module 300, and the maximum transmission rate is usually no more than 30Mbps (megabits per second). For the communication frequency band where the LTE communication module 300 is located, in areas where the base station (or cellular base station) signal coverage is poor, such as basements, warehouses and other locations, there will be unstable data transmission or situations where data transmission cannot be performed. In addition, for the communication frequency band where the Wi-Fi communication module 400 is located, since its operating frequency is relatively high (including 2.4GHz, 5GHz and / or 6GHz), the transmission power is low, so its performance in passing through obstacles (such as walls) is weak, and the transmission distance is also limited, usually for example no more than 30 meters or 40 meters.

[0080] For mobile communication devices, when the Wi-Fi communication module is turned on, the LTE communication module is in standby mode, and the mobile communication device realizes network communication and performs wireless data transmission through the connection between the Wi-Fi communication module and the adjacent wireless network access point. When the Wi-Fi signal quality is poor (including signal strength below the threshold or data packet loss rate above the threshold), it switches to other communication methods. If it switches directly to the LTE communication module, and the base station signal coverage in the area where the mobile communication device is located is poor or weak, unstable data transmission or inability to perform data transmission will occur. Therefore, in the technical solution of the present application, the Halow communication module is in the second selection priority, and the Halow communication module is used to make up for the problem of insufficient network transmission distance of the Wi-Fi communication module. In theory, a Halow access point can support Halow communication modules within 1000 meters to communicate with it for data transmission. At the same time, through the setting and application of the Halow communication module, the setting of wireless network access points (Wi-Fi access points) can be greatly reduced.

[0081] When both the Wi-Fi communication module and the Halow communication module are turned off, the LTE communication module is turned on, and data transmission is achieved through communication between the LTE antenna of the mobile communication device and the cellular base station. The mobile communication device includes a fixed-mounted mobile communication device and / or a mobile-deployed mobile communication device.

[0082] In some embodiments, the mobile communication device includes, for example, a desktop cash register device, a self-service cash register device, or a handheld cash register device.
