Wireless operators have quietly embarked on acquiring dark fiber – a trend that was picked up in 2013 and accelerated in 2014. Verizon is leading this activity and rolling out dark fiber to their cell site. But why specifically have carriers decided on dark fiber rather than continue lease capacity? I think the answer has… Read More »
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 evolution of wireless networks to a HetNet architecture is inevitable, but the question for industry players and investors is what form will it take. This is because there is no single approach to small cells, but rather there are multiple ways to densify the network. Making misplaced bets is common in the technology space,… Read More »
The evolution of wireless communications has spawned many innovations but the cellular concept where base stations are dispersed to meet coverage and capacity requirements remains constant. This is about to change, sort of, if Cloud Radio Access Network (CRAN) architecture lives up to its vision. What makes CRAN such an interesting development is that it… Read More »
