Spanish telecoms giant Telefónica has demonstrated its Long Term Evolution (LTE) technology working in the real world.
The operator has taken its fourth-generation prototype network out of the lab for the first time, hooking it up to an existing 2G and 3G network in use by normal mobile customers.
With commercial WiMax deployments already underway, the LTE demonstration marks a significant milestone for the platform, and takes it another step closer to reaching maturity and the $70bn (£49bn) revenues predicted by analyst firm Juniper Research.
The demonstration was held in Madrid, and featured a VoIP call and a video call using the LTE mini-network installed at the headquarters set up specifically for this purpose by Ericsson.
A video conference, and data and image download test saw the connection reach speeds of over 140Mbit/s, roughly 10 times faster than the current speed offered by the 3G network over HSPA technology.

4g Standards will Coexist
It seems inevitable that like so many standards in the telecom industry, the LTE and WiMAX wireless radio standards will coexist in the marketplace and find unique niche applications where they are best suited. In each scenario, the 4G RAN capabilities will be complemented by an end-to-end IP backhaul network infrastructure. The anticipation of heavy data intensive applications will further fuel the demand to upgrade network capacity. David@BTR http://www.4GequalsIP.com
