Chronicling the quiet end of wireless networks, from CDPD to WiMAX

As wireless operators continue consolidate networks through acquisitions, roll out 4G LTE and make way for 5G wireless, they are also shutting down legacy wireless network technologies. Whether it's CDPD, iDEN, CDMA or WiMAX, a number of key wireless operators including T-Mobile (NYSE:TMUS), Sprint (NYSE:S), and AT&T Mobility (NYSE: T) are in some stage of shutting down their legacy wireless network infrastructures. Phil Goldstein, editor of FierceWireless, takes a look at six wireless network shutdowns taking place in a new feature, A look at the wireless industry's shuttered networks.

T-Mobile US shut down MetroPCS' legacy CDMA network, and in September, AT&T Mobility will do the same for the CDMA network it inherited from Leap Wireless. Meanwhile, Sprint confirmed last year it will shut off service on its mobile WiMAX network on or around Nov. 6, 2015. Read the Special Report here.
