Metropolitan Police, Fire, and other emergency response agencies utilize radios and low bandwidth communication systems to transmit voice and data to mobile vehicles. The Federal Government recognized that the lack of public bandwidth was hindering public safety and homeland security. They mandated in 2002 that a new frequency band, the 4.9GHz band or more specifically, 50 MHz in the 4.9GHz band, would be assigned for high-power (up to 2 watts) data/voice equipment that follows certain specifications. Later there was a secondary low-power mask for units compatible with 802.11a specifications added. The new specifications allowed communication with fixed and mobile devices up to 10 miles or more at speeds of 20Mbps or better. This much bandwidth opens up a whole new range of capabilities.
