Orange has launched technical and marketing trials of UMTS TDD (TD-CDMA) targeting the enterprise market in Lille, France with equipment supplied by IPWireless. UMTS frequency allocation traditionally comprises a paired band (FDD) and an unpaired band (TDD). Like nearly all UMTS operators, Orange has been allocated, depending on the country, a number of FDD frequencies and a block of TDD frequencies. To date, most UMTS deployments have focused on WCDMA utilizing the paired frequency bands.
Orange’s large-scale WCDMA deployment will support delivery of a variety of services including voice, SMS, supplementary services, videophone, and packet data transmission at data rates of 64/128Kbps and 64/384Kbps, higher with the planned FDD band evolution to HSDPA. http://www.ipwireless.com/http://www.orange.com/
