Sprint has officially launched its WiMAX broadband wireless network in Baltimore, marking the technology’s long-awaited debut. The service, dubbed XOHM, is based on the 802.16e standard and delivers download speeds of 2 Mbps to 4 Mbps with prices starting at about $25 a month.

That’s quite reasonable pricing, but customers will still need to outfit their PCs with WiMAX compatible gear. According to the company, users in Baltimore can begin accessing the network using XOHM-branded Samsung Express laptop air cards that cost $59.99 or a ZyXel modem that goes for $79.99. Sprint hopes to expand the service to Washington D.C. and Chicago before the end of the year and other major cities sometime in 2009.
