Verizon Director Dishes On The Company’s Roadmap, LTE-Advanced.

How insanely devoted is Verizon to stomping the competition? Very. Today Praveen Atreya, director of network technology for Verizon mentioned to LightReading that the company is not only working feverishly to get LTE coverage nationwide, they’re already looking towards LTE’s replacement — LTE-Advanced (read: the original, “real” 4G before marketing buzzwords took over). Atreya admitted that such network upgrades were still in the very early stages.

Meanwhile Verizon’s director of technology applications, Larry Rau, told LightReading that VZW is still testing Voice Over LTE (VoLTE) in two pre-commercial markets and that public launches are unlikely until later in 2012. If you recall, one of the original market points of the LG Revolution Android device was that it was supposed to support VoLTE. Unfortunately as we now see, the network just isn’t ready quite yet.

With all that said, we don’t see LTE-Advanced going live until mid-2013(ish) at the earliest considering VoLTE (and data-based LTE) will need to be widely available and robust if VZW is serious about moving away from CDMA in an effort to free up more spectrum for LTE. Multi-year waiting aside, we’re eagerly anticipating LTE-Advanced’s 1 Gbps potential.

LTE Advance Network Demoed. Real 4G Brings 900+ Mbps Speeds To The Table.

Even though carriers have accepted the challenge of watering down and ruining the “4G” moniker, that hasn’t stopped some speed-hungry Swedes from banding together (literally) some spectrum to show off LTE Advanced (read: real 4G). While “normal” LTE top out around 100 Mbps, LTE Advanced can hit has high as 1 Gbps. In Ericsson’s test over yonder in Sweden, the top speed shown hovered above 900 Mbps and while driving around Stockholm in a van no less.

Obtaining such performance comes in part because literally no one is using this network. Though even then, the use of bigger chunks of spectrum are said to be more apt at handling large traffic influxes while also keeping data throughput higher. With that said, Ericsson used 3 x 20MHz spectrum chunks aggregated into one gigantor 60MHz aggregated slab of spectrum, Ericsson multi-mode, multi-standard radio base station, the RBS 6000, and 8×8 MIMO technologies. As you’ll see in the video after the break, the end result is drool inducing if not a bit anticlimactic. Though we’re sure we’ll be singing a different one once commercial networks start going live in 2013.

Grab your goggles and hop on past the break…
