Polkomtel, one of three mobile telephony operators in Poland, launched its commercial High Speed Downlink Packet Access (HSDPA) network in the Warsaw area, offering speeds of up to five times faster than its current WCDMA service. Polkomtel and Nokia have worked together since 1996. Nokia supplies the HSDPA under extension of the existing frame agreement for GSM/EDGE and WCDMA 3G, signed in 2005. http://www.nokia.com
