IPWireless introduces TD-CDMA Network in a Box targeting rural operators, public safety | Fierce Network

On the heels of announcing its LTE research partnership with Sony, TD-CDMA technology inventor IPWireless introduced the availability of what it calls "Network in a Box," a self-contained modular mobile broadband network product that enables rapid deployment of a TD-CDMA network in the 2.5 GHz and entire 700 MHz range. IPWireless is targeting rural network providers and public-safety users. Rural operators may not migrate to 4G let alone 3G networks in the near future because of the expense. The...
