Sprint spent some time today talking about its plan for deploying CDMA 3G, and WiMax and Long Term Evolution 4G devices over the next few years. While the company didn't share specific details about particular handsets, it spoke in general terms about how it will move forward with its 3G and 4G services with respect to network technology and spectrum support. Sprint said that it will integrate 800MHz CDMA Class 10 in most 2011 devices and all 2012 devices. It will use its 800MHz CDMA assets to supplement its current 1900MHz PCS voice services. Sprint will also build 1X Advanced into its 2012 device portfolio. LTE will debut in devices by the middle of 2012. Sprint said that WiMax will still be included in its products, but will overlap and sell both WiMax and LTE devices at the same time. Handsets released in 2012 will be dual-mode CDMA/LTE, with LTE running in the 1900MHz A-G Bands. It will launch multi-mode CDMA/WiMax/LTE mobile hotspots. CDMA/WiMax devices will be sold through 2012. The company said that there will be about 15 CDMA/LTE devices available in 2012, including handsets, tablets, and data cards. Samsung, LG, RIM, Kyocera, Sierra Wireless, Google, Novatel, Qualcomm, VIA, HTC and Motorola have voiced their support for Sprint's network plans.

SV-DO and EV-DO Rev B 800-900 multi carrier

If Sprint presently is not going to deploy any LTE in its SMR 800-900 MHz spectrum, then Sprint really needs to maximize the potential of its CDMA band class 10 roll out:

*SV-DO for simultaneous 1X voice and EV-DO data
*EV-DO Rev B with 2X or 3X multi carrier deployment for reduced latency and higher peak downlink data rates of 9.8 Mbps or 14.7 Mbps

Sprint's SMR 800 MHz X block nationwide collection of licenses have bandwidth of 12 MHz (6 MHz x 6 MHz paired) per market and can accommodate up to four contiguous CDMA 1.25 MHz carrier channels.

Sprint's SMR 900 MHz A-T blocks nationwide collection of licenses have aggregate bandwidth of up 10 MHz (up to 5 MHz x 5 MHz paired) per market and can accommodate up to three contiguous CDMA 1...
AJ, you always seem to bring some great insight and information to these forums and I applaud you for it. I only wish I understood it all the time, haha.

LTE 1900: likely 5 MHz x 5 MHz, no 10 MHz x 10 MHz

Nationally, Sprint has a PCS 1900 MHz licensed bandwidth average of ~32 MHz per market. This weighted average includes ~22 MHz bandwidth per market of PCS A-F block spectrum that Sprint has held for 10-15 years and exactly 10 MHz bandwidth per market from its new PCS "G" block nationwide collection of licenses that Sprint has received as compensation for its part in the 800 MHz public safety reconfiguration effort.

In many major markets, Sprint has deployed 3-4 CDMA1x and 3-4 EV-DO carrier channels in its traditional PCS A-F block spectrum. At 2.5 MHz (1.25 MHz x 1.25 MHz paired) bandwidth per carrier channel, Sprint is already using 15-20 MHz of its ~22 MHz average licensed bandwidth. So, in many markets, Sprint has little PCS A-F blo...

I believe your post is expressing the current Sprint situation as rolling out their LTE alone.

"If" Lightsquared is permitted to advance forward with licensing 20Mhz of their 1600Mhz spectrum which Sprint is to deploy, how will this effect ...

Sprint is running out of money
