Westell Technologies' ClearLink DAS addresses "near-far" data problem


Westell Technologies introduced the ClearLink DAS, a distributed antenna system that the company says can solve the "near-far" issue. In other words, when a device gets a data signal from a DAS and a simultaneous signal from a distant macro tower, performance can be degraded.

Westell executives said that the 'near-far' issue is particularly problematic with LTE systems and will likely get worse as carriers launch LTE in additional bands. Westell said the problem can increase when carriers use frequencies that are not continuous. For some DAS equipment makers, points of interface and DAS equipment cannot be contained on the same chassis. This is not true of Westell's ClearLink DAS which permits the combination of both of these kinds of equipment in one chassis. Release
