LTE developers and aficionados alike can point their web browser to Verizon Wireless’ webpage to pre-register for a webcast starting 11 AM ET on Wednesday, January 20, 2010. The webcast will review the updated specifications for 4G wireless devices that will run on Verizon’s 700MHZ LTE network. Updates include but are not limited to information on address network access, SMS requirements, data retry tests, lab and signaling conformance, and details on the device approval and introduction process. If the terms “Radio Access Network” and “Retail Product Compliance” strikes a chord with your super-technical side, then you can sign up for and login to Verizon’s open development website to preview the updated specifications in PDF format right now. For those that just want to know when our mobile phones can pull down 12Mbps, Verizon is still planning to launch LTE in 25 to 30 markets in 2010 and cover most of its current 3G footprint with LTE by the end of 2013. We’re sure there will be a map for that when Verizon’s 4G finally launches.
