TechAlt's interoperable solution bridges the gap between previously incompatible police, fire and EMS communications without the need to purchase new radios. It links first responders with the police station, fire station, and state and federal agencies through voice, video and data over multiple wireless networks. TechAlt is a complete interoperable solution for routine operations, catastrophic events, and long-term collaboration among federal, state and local agencies. TechAlt's systems transmit across radio, 802.11, cellular, satellite, and other networks, seamlessly switching to the strongest signal and sending audio, data and live video to first responders via laptops, handheld PDAs and cell phones.
