Why LTE May Not Solve Congestion Woes
While LTE technology performs well now, that probably will change as congestion increases, according to a new Actix study. Here’s more: Smartphones on 3G networks spend almost 85 percent of their active time generating data traffic and only 10 percent of it on voice; data sessions in congested areas often fall to less than video-ready speeds; Apple subscribers use more data per session than do Android subs, with BlackBerry subs using 50 percent less data than Android and 30 percent less than Apple; 20 percent of locations garner 80 percent of network traffic, while 5 percent account for more than half of that traffic; and data rates drop off by as much as 50 percent when users go indoors, due to increasing network congestion.

Beam-Forming Small Cells And HetNets
A joint NEC/Ubidyne report tracks the impact of 3D beam-forming small cells on the latest active antenna technology by benchmarking passive small cells with active beam-forming small cells that could be part of future LTE/4G heterogeneous networks (HetNets). The background: An active 3D beam-forming small cell comprises several antenna elements and transceivers arranged in a matrix enabling flexible vertical and horizontal beam-forming, including beam shaping independent in the downlink and uplink. The two say 3D beam-forming can lead to an average 40-percent macrocell load reduction (aka offloading). Beam-forming also can help reduce intercell interference.
