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 »
The market awaits the arrival of outdoor small cells, but the wait continues. When small cell deployments will happen keeps sliding from one year to the next. I have always thought that some in the industry have been too optimistic on small cells deployment timelines and they have ignored important facts that define the deployment… Read More »
Small cells raise a number of practical implementation questions which are yet to be resolved. One such question is whether small cells should operate in the same frequency band as the macrocell layer (co-channel deployment), or on a different frequency band. The question has profound implications to operators, vendors, and to regulators alike. To clarify,… Read More »
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 »
