What is the best Stack Exchange site that answers questions regarding digital communications and wireless communications, and questions regarding OFDM, CDMA, LTE, etc.?
This topic has been on Area51 three times in the past and has never gotten enough traction. Mostly because there is several overlaping sites already handling these topics.
The fine folks on EE.SE are more than willing to answer questions about wireless communication technology and theory.
While the guys over on Sec.SE can answer more about the encryption, Authorization/Athentication/Accounting, and general security with wireless communication.
Finally NetworkEngineering is the best place to follow up for any network related questions.
I am supporting the creation of a Telecommunications QA on StackExchange.
I know this has been proposed several times but I truly believe there is an audience. The main challenge I face is that people interested in this idea do not know Stack Exchange and find it complicated to register on Area 51, verify the email, support and vote for the site (it is not that straightforward).
See here to support it: http://area51.stackexchange.com/proposals/104688/telecommunications
