Telefonica with Alcatel-Lucent and Samsung support demonstrates smart, 2.6 GHz, 100 Mbit/s 4G network
Based on Alcatel-Lucent’s lightRadio™ technology, Telefonica’s network is a revolutionary first step toward a real "HetNet" network, which greatly improves mobile coverage by bringing small-cell base stations closer to the customer. In this deployment conventional radio base stations co-exist with 4G metro cells (small base stations incorporating antennas and radio) working on the same frequency and with no interference. As a strong supporter for Telefonica’s LTE service initiative, Samsung is also presenting the first LTE smart mobile devices for band 7 (2.6 Mhz), GALAXY S II LTE smartphone and GALAXY Tab 8.9 LTE tablet, which can be used on this latest high-capacity network.
The most significant feature of Telefonica’s LTE network is its increased capacity — with each cell comfortably supporting 30 people browsing simultaneously with average speed of 30 Mbps. Tests conducted on this network show that a 400% increase in capacity can be made available to users compared to a conventional network design, and that significantly higher capacity gains could be delivered with denser metro-network design. The network supports speeds of up to 10 times those offered by the 3G network, with download speeds of 100 Mbps, upload speeds of 40-60 Mbps and with latency times of around 20-25 milliseconds.
Another key benefit of the advanced feature network is that it utilizes the same frequency for several network layers, allowing for far more efficient use of spectrum. This solution would also reduce network deployment costs by as much as 40%, as the installation of small-cells significantly reduces the amount of construction, installation and configuration work needed. Additionally, small-cells use less powerful amplification equipment, resulting in energy savings of up to 35% and a guaranteed reduction in environmental impact.
