Sprint 4G Rollout Updates
Thursday, April 12, 2012 - 2:55 PM MDT
A few weeks ago, S4GRU was the first to bring you the news of the HTC codenamed "Jet" that was recently unveiled as the HTC EVO 4G LTE headed to Sprint this summer. Today, the EVO 4G LTE applications hit the FCC OET (Office of Engineering and Technology) database. S4GRU brings you the technical rundown, including some important revelations.
- CDMA1X + EV-DO band classes 0, 1, 10 (i.e. CDMA1X + EV-DO 850/1900/800)
- LTE band class 25 (i.e. LTE 1900; PCS A-G blocks)
- LTE 5 MHz and 10 MHz channel bandwidths
- LTE UE category 3
- SVDO and SVLTE support, including SVDO or SVLTE and simultaneous 802.11a/b/g/n Wi-Fi tether
- Maximum RF ERP: 20.43 dBm (CDMA1X 850), 18.74 dBm (EV-DO 850), 22.98 dBm (CDMA1X 1900), 18.44 dBm (EV-DO 1900), 20.01 dBm (CDMA1X 800), 18.75 dBm (EV-DO 800), 19.85 dBm (LTE 1900)
- Antenna gain: -2 dBi (CDMA1X 850/1900/800), -3.5 dBi (EV-DO 850/1900/800 and LTE 1900)
- LTE antenna configuration 1x2 (i.e. 2x2 downlink MIMO)
Prima facie analysis, no LTE 800 nor TD-LTE 2600 support comes as no surprise. But SVDO is a nice perk, as internal Sprint documents had not indicated its inclusion. Furthermore, SVDO/SVLTE plus simultaneous Wi-Fi tether capability really covers all of the connectivity bases. Most disappointing, however, is the rather low ERP output. While the EVO 4G LTE has a plethora of radio capabilities, it does not look to be a stellar RF performer, perhaps the consequence of the aluminum unibody in place of the polycarbonate unibody used in the more direct members of the HTC One X family of handsets.
