14 Page 14 CONFIDENTIAL EZRadioPRO Why use IAI with +20dBm?? –Extended Range  2000 meters !!! –Only integrated +20dBm PA available!!! –Significant cost savings vs. purchasing an external PA –Highest Efficiency PA available  battery life –Can use low-cost antenna and overcompensate with higher output power to achieve same effective range  cost savings –Automatic ramp-up and ramp-down of PA  no spectral splatter

15 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 902-928MHz Will need to evaluated on case by case basis for each market

16 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!!!

17 Page 17 CONFIDENTIAL EZRadioPRO Antenna Diversity Advantages of Antenna Diversity –Counters Multi-path Fading and Antenna Polarization (Some of you may have seen these effects within the EZRadio product line or Competitor chips) –+8-10dB Gain in Link Budget for typical system –Algorithm completely integrated –No competitor has this feature (Very cumbersome and time consuming to do over the SPI with a microcontroller)

18 Page 18 CONFIDENTIAL EZRadioPRO What is Antenna Diversity? Two antennas in system EZRadioPRO will choose the best antenna for optimal performance Gain 8-10dB in Link Budget Gain Common feature used in cell/cordless phones to avoid multipath/fading

19 Page 19 CONFIDENTIAL EZRadioPRO What is the Packet Handler?? Typical Packet Structure Shown Above Preamble, Sync Word TX Header, Packet Length, and CRC fields set through SPI registers ALL that needs to be loaded into FIFO is “Data” EZRadioPRO will automatically construct/deconstruct the packet
