Page 15 CONFIDENTIAL EZRadioPRO Implications for Using +20dBm –Different Regulatory Agencies restrict output power in certain bands. –Most applications will need to implement FHSS to take advantage of +20dBm US FCC – Can use +20dBm with FHSS MHz Will need to evaluated on case by case basis for each market
Page 16 CONFIDENTIAL EZRadioPRO FHSS - Huh?? What is FHSS? (Frequency Hopping Spread Spectrum) –Carrier Frequency is changed by pseudo random sequence –More Resistant to interferers –Difficult to intercept –Most importantly allowed to transmit up to +20dBm by FCC!!!
