LG LS740: Could it be a midrange RF powerhouse?

Sprint 4G Rollout Updates

This year is shaping up to be an interesting one for Sprint handsets. In 2012, 15 LTE devices were released on the then brand new Sprint LTE 1900 network, while last year saw a 100 percent increase to 30 devices. And this year could be just as big of a year as last. So, what better way to start 2014 off right than with a tri-band LTE phone?
We present S4GRU's first FCC OET authorization article of 2014, the LG LS740, a midrange LG tri-band LTE handset not yet announced but presumably headed to Sprint. RF stats are pretty high for a midrange device, as you can see below.
- CDMA1X + EV-DO band classes 0, 1, 10 (i.e. CDMA1X + EV-DO 850/1900/800)
- LTE bands 25, 26, 41 (i.e. LTE 1900/800, TD-LTE 2600)
- band 25 LTE 3/5/10 MHz FDD carrier bandwidth
- band 26 LTE 1.4/3/5/10 MHz FDD carrier bandwidth
- band 41 LTE 10/15/20 MHz TDD carrier bandwidth
- LTE UE category 4
- 802.11 b/g/n Wi-Fi
- 802.11n MCS index 7 (single spatial stream, 20 MHz carrier bandwidth, 400 ns guard interval)
- SVDO and SVLTE support absent
- RF ERP/EIRP maximum: 22.121 dBm (CDMA1X 800), 21.081-22.621 dBm (CDMA1X/EV-DO 850), 23.14 dBm (CDMA1X/EV-DO 1900), 25.06-26.82 dBm (LTE 1900), 22.901-25.211 dBm (LTE 800), 24.9-26.29 dBm (TD-LTE 2600)
- NFC
- Antenna locations: notably absent from this article as LG has an on again/off again attitude about when it releases antenna diagrams
- Simultaneous transmission paths: (see FCC OET diagram below)
According to the FCC OET docs and Sprint UA profile, system specs for this device are as follows:
- Qualcomm MSM8926 (aka Snapdragon 400)
- 4.7 in screen
- 540 x 960 screen resolution
- Android 4.4 KitKat
- Bluetooth 4.0
- 2 GB RAM
- 32 GB ROM
- microSD slot absent
- 1.3 MP front camera
- 8 MP rear camera with full HD (1920 x 1080) video recording
- sealed battery
Expect this device to have a mid to late spring release, and it might be the replacement to the LG F3 (LS720) Sprint released last year.
