I will beg to differ. The cellcos are constantly changing radios. My dealing are with AT&T and VZW. The old analog bays were swapped for CDMA(Verizon) and TDMA(AT&T) style radios. Completely different radio sets. Then LTE launched. Verizon installed brand new Lucent LTE base stations. Now with xLTE, the radios are changing again. Even within Verizon, they switched manufacturers for the CDMA and PCS gear from Lucent to Nortel. Then back to Lucent for LTE. They are constantly swapping radio systems.
I have been involved in network upgrades and radio installations for Verizon and AT&T for years. Not so much anymore. Hard to find good help and I dont feel like running the roads to install that stuff anymore.

Probably limited only by antennas. No way are they changing out basestations for every protocol or spectrum change like they did in the past. There are even systems where the software defined radio is remote in a centralized datacenter, I think its called C-RAN.

I think the only way Telrad might be odd with their SDR is that they actually made different firmware to convert the unit from WiMax to a completely different physical layer. The only other big SDR change I can think of in the WISP marketplace was Moto's transition from software scheduling to hardware scheduling.� Maybe some of you old men remember another incident to refute this statement, but I think I'd say that having the ability to define the radio in software doesn't mean they'll actually do it. SimpleTest Stefan: can they upgrade their WiMAX base stations to LTE? The answer is No. Case closed.

Just google Purwave and SDR and you find some.
