Narrowband data communication system and wireless narrowband data communication method

Abstract

The invention discloses a narrowband data communication system and a wireless narrowband data communication method. A narrowband data communication terminal network system comprises at least two terminal branches, wherein each terminal branch is in wireless connection with other terminal branches in the terminal network system and used for receiving control instruction information sent by other terminal branches and executing corresponding control instructions according to the control instruction information or sending the control instruction information to other terminal branches, so that point-to-point communication among the terminal branches is realized; and high-reliability bidirectional wireless communication technology is easy to use, has close distance, low speed, low power consumption and cheap market positioning, supports a transmission control protocol / Internet protocol (TCP / IP) and an embedded device, and is suitable for a large-scale network. The wireless narrowband communication technology of the invention can support the application of the Internet of things and a wireless home network in China at present and has infinite development potential.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a narrowband data communication system and a communication method for a terminal network system.

Problems solved by technology

However, infrared technology only supports point-to-point line-of-sight connections, and the optical path of the transceiver device is blocked and cannot bypass obstacles, making its communication distance short

The high-bandwidth characteristics of Bluetooth technology make it more suitable for multimedia devices such as audio, video, and images, as well as devices that need to frequently exchange large amounts of data, making it unsuitable for wireless narrowband data transmission.

[0007] Therefore, the existing wireless narrowband communication technology still needs to be improved and improved.
