The full list of radios and band supported by the RM-845 are:
- CDMA 800 and 1900 (CDMA2000 1xRTT + Ev-Do Rev A)
- LTE 700 Upper (Band XIII)
- GSM/WCDMA 850 and 1900
These bands tie in precisely with Verizon's network, and the combination is unique to Verizon (most notably the presence of LTE Band XIII). The handset will use the CDMA and LTE bands for voice and data in the US. The GSM and WCDMA bands are present for when the phone is roaming internationally.
The test results note that RM-845 can be used in SVLTE mode (simultaneous voice and data). Supporting SVLTE requires an extra antenna, which takes up more space and adds to the weight of the device. It's partly for this reason that the iPhone 5 does not support SVLTE.
Verizon is set to range a number of Windows Phone 8 handsets, although no official announcement has yet been made. HTC, when launching the 8X and 8S included Verizon as one of its operator partners in a press release, so it's a reasonable assumption one or both of HTC's handsets will be available on Verizon. It now appears certain, as suggested by a number of rumours, that at least one Nokia handset will also be available.
