Wireless local loop communication system

A wireless local loop system having an integrated one-piece structure, said one-piece structure comprising:

• a speaker,
• a microphone,
• a RF transmission/reception mechanism for receiving a RF signal from an antenna providing the signal after converting it to a digital baseband signal to a MSM (Mobile System Modem),
• a CODEC for coding and decoding analog and digital voice signals communicated between the microphone and the MSM,
• a data interface mechanism for connecting the WLL system to an external terminal,
• memory for storing data related to user services and a main program for controlling the MSM,
• a power supplying mechanism having a charge battery for supplying power to the respective integrated system components, and
• a keypad having at least a button to establish a communication connection.

A method of communication in a wireless local loop (WLL) system having an integrated one-piece construction comprising a built-in speaker and microphone to respectively present and capture analog voice signals, the method comprising:

• receiving a RF signal from an antenna,
• producing an IF (Intermediate Frequency) signal from the RF signal,
• converting the IF signal into a digital baseband signal,
• providing the digital baseband signal to a MSM (Mobile System Modem),
• decoding the digital baseband signal from the MSM into an analog voice signal, and
• adjusting levels of respective voice signals.
