Nokia Siemens Demos First PTT-Over-LTE Call

Mar 3, 2011, 3:30 PM by Eric M. Zeman

Nokia Siemens Networks and Harris Corporation today announced the successful completion of what they call the world's first push-to-talk voice call over Long Term Evolution. The calls were made in and around the Dallas-Ft. Worth airport using Harris-made radios and two separate LTE towers. Harris and NSN were able to make multiple PTT calls over the LTE network while simultaneously streaming video and roaming between the two towers. The PTT over LTE system is also fully compatible with P25 networks. The companies believe that this demonstration proves LTE can be used successfully by public safety for vital communications.

Since their already planning on turning off the IDEN netwqork in 2013, and since their already considering LTE, Sprint might as well use this technology to replace IDEN and still have PTT.

Ha, I beat Slammer to it 😁

This service would actually be more beneficial in South America. PTT is actually a very popular feature there.
