I have an MTS wireless plan with an older Blackberry CDMA smart phone. For the past year I have used a booster to receive a signal from the Bissett tower at Beresford Lake. Over the past few months reception has decreased and for the last month I have not been able to receive any signal at all. Has there been changes in signal delivery in this area? Also how close is the upgrade to completion for this area? Will this upgrade also include increased signal strength?
