A new report from Visant Strategies finds that the market for legacy mobile switching vendors will remain strong, even as there is a move to I/P-based switching. The report suggests the continued deployment of CDMA EV-DO, WCDMA/HSDPA and GSM/GPRS/EDGE base stations will lead to a market for all mobile network components at an ever-increasing rate. Global softswitch sales could reach more than $6 billion in 2011, while IP-based and IMS-based gear could see revenues nearly double that amount in the same year.
