WRC-15: Win Some, Lose Some

By | November 27, 2015

WRC15 concluded with new spectrum assigned for mobile services: L-band:  1427-1518 MHz is now assigned for fixed and mobile services. The L-Band is used for mobile satellite services. Technical measures need to be developed for co-existence with mobile satellite in 1518-1559 MHz. The 1350 – 1400 MHz was also a target for IMT, but it… Read More »

Raising the Stakes in 3.5 GHz: LTE-Advanced Achieves 1 Gbps

By | June 22, 2014

The 3 GHz frequency bands stands at the upper limit of what is considered today as viable spectrum for mobile communications. But bands 42 (3400 – 3600 MHz) and 43 (3600 – 3800 MHz) are not only the ‘last frontier’, but more importantly, they provide the widest spectrum of any other band (200 MHz). Additionally,… Read More »

From LTE-U to LTE-DSA: Solving The Capacity Crunch

By | March 31, 2014

The proposal by Qualcomm to enable LTE operation in unlicensed band (LTE-U) received a warm response from some (e.g. Ericsson, Verizon) and not so warm from others especially incumbents with strong legacy in Wi-Fi in both the vendor and operator communities. The contentious issue center on co-existence of LTE and Wi-Fi in the same band… Read More »

LTE-Advanced, 3.5 GHz, Small Cells and Neutral Host Services: A Powerful Mix to Abundantly Increase Network Capacity

By | September 16, 2013

At a recent GTI event in Japan, Huawei demonstrated 770 Mbps peak throughput in a market trial of LTE-Advanced in 3.5 GHz spectrum. This was achieved with TD-LTE access mode with carrier aggregation. The trial showed 500 Mbps average throughput over multiple sites. Furthermore, Softbank demonstrated the ability to provide 1.2 Gbps peak throughput using… Read More »
