Description

technical field [0001] The invention belongs to the technical field of mobile communication, and more specifically relates to a wireless fixed telephone device based on a CDMA system. Background technique [0002] At present, the penetration rate of fixed wired telephone is high, the technology is mature and stable, and it is easy to use. However, fixed wired telephone has some disadvantages that are inconvenient to use. The work speed is slow. For the user, when the office or residence is moved to change the address, it is necessary to go to the telecommunications bureau to handle the transfer and change the number, which delays and affects working hours. And the fixed wired telephone can't be used on some inconvenient wiring or ground lines not reaching places or areas such as suburbs, lakes, islands, rural areas and mobile carriers such as automobiles and ships. Fixed wired telephones are based on voice services and lack communication of data information. Contents of t...
