Well, ideally you shouldn't have to deal with them because they'd be obtained from the operator via OMA-DM -- however, there is no open source OMA-DM client and implementing it is not a trivial task. > Kind of like how any Wi-fi card can connect to any open access point? In theoretical terms we could do the same...but...WiMAX's number of possible channels you have to scan is staggering high, so that it is not-practical (it'd kill your battery and then your patience too). Just for the common parameters where, for example, Clearwire seats FFT: 1024 bandwidth: 10000 MHz frequencies: 2.2 GHz -> 6 GHz [the freq range is made up, but it more or less picks up every frequency where I've seen networks, in labs and different operators / test operations around the world] so the way the wimax channels are deployed are: take that range, break it up in steps of 250 KHz, with a bandwidth of 10 MHz (others are possible) -- note they might overlap! --. Scanning the 1520 channels (6 - 2.2 G / 250 KHz) is not a trivial task; hence it is done so the carrier tells you which channels they operate in, the XML file. I wish there was a way for the carrier to bcast that information (along with the EAP authentication parameters), but there is not :(
