Hopefully I won't start too much of a fire with this post, but I read something interesting today in AT&T's second quarter 10-Q filing. It's about half way down.

Basically, AT&T indicate they plan on turning off their 2G cellular service by January 1, 2017 to free up bandwidth. I seem to remember reading that the 2011/2012 LEAF's use a GPRS cellular modem (2G) on AT&T service to do the telematics communication from the car to Nissan's data center. From AT&T's disclosure, it would seem that the telematics service in our LEAF's will cease operating sometime in 2016 and certainly by 2017. Maybe there will be another carrier (I think unlikely) or perhaps new technology will have to be installed to continue using Carwings.

Also as part of our ongoing efforts to improve our network performance and help address the need for additional spectrum capacity, we intend to redeploy spectrum currently used for basic 2G services to support more advanced mobile Internet services on our 3G and 4G networks. We will manage this process consistent with previous network upgrades and will transition customers on a market-by-market basis from our Global System for Mobile Communications (GSM) and Enhanced Data rates for GSM Evolution (EDGE) networks (referred to as 2G networks) to our more advanced 3G and 4G networks. We expect to fully discontinue service on our 2G networks by approximately January 1, 2017. Throughout this multi-year upgrade process, we will work proactively with our customers to manage the process of moving to 3G and 4G devices, which will help minimize customer churn. As of June 30, 2012, approximately 12 percent of our postpaid customers were using 2G handsets. We do not expect this transition to have a material impact on our operating results, but will continue to evaluate the financial impact of transitioning customers from 2G devices to 3G or 4G devices.
