Verizon Says LTE-Advanced Features On Deck for 2015
Verizon Wireless has a number of improvements to its LTE network planned for 2015 that will boost coverage, capacity, and speeds, according to Mike Haberman, vice president of network support for Verizon. First, Verizon will implement carrier aggregation, which pairs disparate spectrum bands so they act as one. For example, it will use carrier aggregation to pair LTE service on its 700MHz spectrum with its AWS spectrum. The combined spectrum (20x20Mhz channel in AWS and 10x10Mhz channel in 700MHz) will result in 30x30MHz channels. Haberman said this will help improve peak speeds, though average network speeds will remain about the same. Verizon will eventually add carrier aggregation to its PCS spectrum as it ramps down EVDO in favor of LTE. Beyond carrier aggregation, Verizon plans to introduce eICIC (enhanced inter-cell interference coordination), which lets the macro cellular network coordinate coverage and reduce interference with small-cell deployments in the same area. Last, Verizon said it will introduce higher orders of MIMO (multiple in, multiple out) to LTE. Verizon's LTE devices all use 2x2 MIMO, but it may upgrade its cell towers to 4x4 MIMO to improve uplink performance. Haberman said Verizon likely won't use 4x4 MIMO on handsets, as the gains in downlink performance likely won't offset the higher cost of the handset.

Verizon Explains Why It Is Refarming PCS Spectrum
Verizon Wireless elaborated today on news it has begun to refarm its PCS spectrum for LTE. Verizon has already deployed LTE on its PCS spectrum in a limited scale across Manhattan and Cleveland, Ohio, with "about 10 other markets" currently in testing.
AT&T Stepping Up Three-Channel Carrier Aggregation
AT&T today confirmed to Fierce Wireless that, like its competitors, it is deploying three-channel carrier aggregation on its LTE 4G network. "We're currently in the process of deploying three-way carrier aggregation on our network," said AT&T spokesman Steven Schwadron in a statement given to Fierce.
Verizon Claims Real-World Speed of 953 Mbps in LTE-LAA Trial
Verizon Wireless says it has attained peak download speeds as high as 953 Mbps in a field test conducted on Boca Raton, Fla. The test was completed with commercially available equipment from Ericsson and Qualcomm using Verizon's cell tower and backhaul.
