Public safety and security forces have the difficult task of bringing order to chaos. Those First responders must be able to communicate during an emergency, reliably and without any security threats. Effective emergency and natural disaster management depend on efficient mission-critical voice and data communication between first responders and victims. Land mobile radio system (LMRS) is a legacy narrowband technology used for critical voice communications with limited use for data applications. The new long-term evolution (LTE) broadband communication technology has the ability to transform the capabilities of public safety technologies by providing broadband, ubiquitous, and mission-critical voice and data support.
