Overview
China stopped providing analog walkie talkie licenses which consequently has created a high demand for more digital walkie talkie applications. The digital walkie talkies transmits speech in the form of digital encoding. DMR (time division),is more widely used and has a communication speed of 9.6kbps so efficient compression algorithms are necessary.
- Digital walkie-talkie advantages:
- Less bandwidth than analog walkie talkie
- Can use encryption algorithm for higher security
- Easy networking
- High quality speech
The Airfast® RF power portfolio brings extreme ruggedness and high gain to mobile radio applications. The high gain of our devices helps eliminate amplification stages and reduce system cost. Plus, the high efficiency of the portfolio allows customers to use smaller heatsinks and housing while improving reliability. The broadband capability of the mobile radio devices enables full performance across each band.
