Nokia Networks and Saudi Arabian operator Zain KSA said they have completed the first trial of LTE carrier aggregation in the Middle Eastern country, as part of a network upgrade project.
Singapore's second largest mobile operator, StarHub, has successfully demonstrated 600 Mbps peak download speeds using Nokia Networks' 4X4 MIMO technology with LTE-Advanced carrier aggregation.
Not everybody in the wireless industry is keen to use the term "4.5G," but FierceWirelessTech decided to informally survey some of the industry's biggest vendors to see what they have to say about it.
Carrier aggregation will pick up as the speed war, fueled by the never ending RootMetrics reports and the subsequent carrier press releases and earnings call citations. AT&T and Verizon's network transformations are "skating to where the puck will be" in an effort to become more agile and drive down costs. So far smaller Sprint and T-Mobile haven't seen this need. There's no doubt that more changes will come about this year.
Sprint CEO Marcelo Claure said that the company is finalizing plans for a massive densification of its network using the company's 2.5 GHz spectrum. Called the "Sprint Next Generation Network," the plan calls for a balance of small cells and macrocells and promises an improvement to both network speed and capacity.
U.S. Cellular is trialing Voice over LTE technology in three markets right now and expects to turn the service on commercially sometime later this year, according to CEO Ken Meyers.
Around 30 per cent (116) of LTE operators worldwide are now investing in carrier aggregation technology.
Sprint has made a lot of news recently about plans to expand its distribution and even bring phones directly to customers. It's all part of an effort to retain the company's customer base and drum up more sales in the hopes of growing net subscriber additions. However, unless Sprint clarifies its brand message and improves its 2.5 GHz LTE network, I fear it will not amount to much.
U.S. Cellular plans to cover essentially its entire customer base with LTE by the end of the year, hoping that expanded access to faster mobile broadband speeds will help its subscriber numbers and churn.
Sprint will use Chicago as a showcase market for LTE Advanced technologies, according to the carrier, as it expands its investment in the city and the surrounding areas.
