Downlink data speeds on LTE networks get a lot of attention, and uplink speeds get much less love. That's mainly because carriers and consumers have long been concerned with what kinds of streaming data can be pulled down from the network to mobile devices. However, chipset suppliers are starting to herald the importance of increasing uplink bandwidth for applications like cloud data uploads and video calling.
Two former rivals are once again teaming up, with Qualcomm Technologies and Ericsson successfully completing an inter-company interoperability testing of LTE Category 9 connectivity with download speeds of up to 450 Mbps.
During Nokia Capital Markets Day 2014 in London, CEO and President Rajeev Suri identified small cells as one of the areas where Nokia Networks will continue to expand and invest.
We have had commercial LTE Advanced (LTE-A) networks since mid-2013 launches by LGU U Plus and SK Telecom in South Korea. Both of these mobile operators made their LTE-A claims based purely on deploying carrier aggregation (CA). None of the other technology advances coming with LTE-A were used. Those features include coordinated multipoint (CoMP), higher orders of MIMO, enhanced inter-cell interference coordination (eICIC), and relay nodes.
Nokia has undergone a lot of changes over the past several years, but there is one thing that hasn't changed. The company can still tie its roots back to the original Finnish company that manufactured not phones but paper, tires and rubber boots.
EE said its LTE Advanced network has now gone live in London, as the UK operator vies with Vodafone UK to become the first operator to roll out the higher speed network across the country.
T-Mobile US is working to enhance its LTE network with Nokia Networks, which indicated that it will enable carrier-aggregation technology for the carrier.
T-Mobile US plans to enhance its LTE network coverage footprint over the next year or so using its 1900 MHz PCS spectrum, all while continuing to modernize its network with LTE Advanced components, according to a senior network executive at the carrier.
Ericsson and Deutsche Telekom's Slovak Telecom business unit achieved data speeds of 300 Mbps in over-the-air field trials for intraband contiguous LTE carrier aggregation. The trials were the first for LTE Band 7, 2.6 GHz spectrum, using a 20+20 MHz configuration in a field environment, Ericsson said.
LTE Advanced is advancing. According to the Global Mobile Suppliers Association (GSA), 79 carriers in total have launched, have deployed or are trialing LTE Advanced technologies in their networks. The GSA also said 21 operators have launched LTE Advanced carrier aggregation in 14 countries.
