11. He also co-authored the " Spread Spectrum Communications Handbook " ( ISBN 0071382151 ). 12. The above systems and radio interfaces are based on spread spectrum radio transmission technology. 13. This technique is now known as spread spectrum and is widely used in telecommunications. 14. A thin client architecture was adopted in conjunction with a spread spectrum radio network. 15. Newer Transmitters use spread spectrum technology in the 2.4 GHz, upper-UHF frequency band for communication. 16. Seeing the commercial possibilities for spread spectrum , Jacobs founded Qualcomm in San Diego in 1985. 17. Digital transmission such as Frequency-hopping spread spectrum provides a level of protection from casual interception. 18. DECT also provides Frequency-hopping spread spectrum over TDMA / TDD structure for ISM band applications. 19. Spread spectrum systems do not violate the Shannon limit.20. Spread spectrum signals are sent down the wire and then the reflected signal is observed.
