Using LTE to Improve Public Safety


Even though much of the 700 MHz spectrum has been auctioned off, a portion has already been reserved for a nationwide emergency response channel to be used by any and all public safety personnel, whether it’s a federal agency or a small town’s fire department.

The proposed technology to build out the nationwide emergency response network is Long Term Evolution (LTE), a 4G mobile technology. In this instance LTE has many advantages, such as global economies of scale, low latency, ease of mobility and high data speeds — up to 10 times what first responders are currently experiencing. LTE delivers downlink speeds between 5 Mb/s and 10 Mb/s and uplink speeds from 2 Mb/s to 5 Mb/s, which is more than enough to send high-quality video from the scene of an incident.

Already Verizon Wireless has begun trials in Seattle and Boston to deploy LTE across the available broadband network, said Diane Wesche, director of product development-government for Verizon Wireless, as reported by

Alcatel Lucent will provide the LTE radio access infrastructure, data packet core, service delivery architecture and backhaul elements, reported Connected Planet.

By the end of 2010, Verizon Wireless plans to begin deployments in 25-30 U.S. markets, said Wesche, who also mentioned that there’s a possibility of creating a collocated public/private network of tens of thousands of base stations.
