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 »

Further Enhanced ICIC (FeICIC)

By | May 7, 2014

Guest post by Faris Alfarhan* In an earlier post, R10-LTE enhanced inter-cell interference coordination (eICIC) techniques for heterogeneous networks were discussed, along with the concept of small cell range expansion. The purpose of cell range expansion is to offload more traffic from macro cells to small cells and hence achieve larger cell splitting gains. By… Read More »

Carrier Aggregation and the Road to Cognitive Radio and Superwide Spectrum

By | January 14, 2014

Often, the least hyped technologies are the most effective, get the widest adoption, and have the greatest impact. Carrier aggregation is one such technology that I don’t think it received its fair share of attention. LTE did bring a number of new features that were not available in 3G, such as MIMO. But MIMO was… Read More »

Reaching The Limits of The Physical Layer: The Slow Shift To Enhancing Efficiency.

By | April 6, 2012

There is a general view that we are rapidly approaching the capacity limits of the physical layer. But as demand for capacity continues to grow, the supply of capacity is tapering off. What to do about this and how to continue to inject capacity is being addressed at standardization meetings. Let’s take a quick look… Read More »

Meeting IMT-Advanced Requirements: A Look Under the Hood of Next Generation Wireless Networks.

By | January 23, 2012

The International Telecommunication Union (ITU) has just approved LTE-Advanced and WiMAX-Advanced (aka WiMAX 2.0) as part of the IMT-Advanced standards. Aside of marketing catch phrases like “putting fiber optical speed on your mobile phone,” the statements about efficiency – being able to transfer higher data rates in lesser bandwidth – are what the industry will… Read More »
