ITU Region 1 seems to be moving closer to permitting unlicensed low power use, RFID etc, around 915-921 MHz but as you say the rest is mobile phones. Given there is no mechanism to command these Sprite ChipSats so they are only on over the USA the use of 902 MHz would seem inapropriate. 73 Trevor M5AKA
Australia has allowed unlicenced low power devices in the range above 915 MHz for some time, and they seem to coexist with GSM phones "next door".
