If voice over 2G and 3G networks is good, and works, and is very low cost for the network operators, why are they all looking toward VoLTE and working as hard as they can to implement it quickly? The answer is that they really want to shut down their 2G systems and then their 3G systems so they can use the 2G spectrum first for LTE and then convert the 3G spectrum to LTE as well.

Wi-Fi Invades the Car? – 04.11.2013

At the time of purchase of the car, you can pay an additional $450 and get 30 months of Wi-Fi in your car, fed by T-Mobile’s 4G network. more
LTE Around the World – 11.28.2012
It should be interesting to put together our session for the Mobile World Congress. We will have access to the GSMA’s Wireless Intelligence group, which has great stats and numbers, and we will be comparing and contrasting them to what is occurring in North America. more
The NPSBN is the most ambitious nationwide network ever undertaken in the United States and it is different from the public commercial networks in many aspects. First and foremost, it must provide the capabilities needed by the Public Safety community, and it must be more reliable. more
Public Safety Advocate Special Edition – 04.15.2013
This morning, the National Public Safety Telecommunications Council (NPSTC) published a document intended for distribution to any and all elected federal, state, and local elected officials. This document states clearly and in plain language why Public Safety Land Mobile Radio (LMR) voice systems MUST be maintained even though FirstNet is building out a new Nationwide Public Safety Broadband Network (NPSBN). more
My advice for the technologists is to continue the good work they are doing but to tone down their technology assessments and predictions with the reality of the time involved and all of the processes and issues that must be addressed and solved, assuming they can be solved. Until then, the Nationwide Public Safety Broadband Network will remain about data and video, while today’s Land Mobile Radio networks are about mission-critical voice. Both networks will be needed for a very long time to come. more
