The integrated services routers with built-in 802.11 access points, AZR services, PoE, and SSG

services comprise the industry’s most comprehensive portfolio of Wi-Fi hotspot routers.

LMR-over-IP Services—Push-to-Talk Radio Interoperability

Push-to-talk radios—otherwise known as LMR systems—are used by companies, local

governments, and other organizations to meet a wide range of communication requirements,

including coordination of people and materials, important safety and security needs, and quick

response in times of emergency. LMR systems provide high reliability, privacy, and local control,

but are isolated and lack the ability to interoperate with other LMR systems and other types of

communications devices. LMR over IP preserves the advantages of LMR systems while

significantly expanding the scope of communications to include remote-access and dispatch

operations from a variety of communications devices as well as interoperability among disparate

radio systems.

Cisco integrated services routers (Table 5) act as LMR “gateways” to the IP network. The router

takes advantage of standard ear-and-mouth (E&M) interfaces with LMR-specific software

capabilities. These gateways link to existing LMR systems and make the critical adaptation of LMR

audio and signaling to IP. The standards-based IP network that interconnects the LMR gateways

provides the intelligent services necessary for real-time, point-to-multipoint traffic. The flexible,

cost-effective solution helps enable multiple LMR systems to be joined together temporarily or

permanently. The scalable, distributed architecture can support just a few to hundreds or

thousands of users over unlimited distances across a public or private network. Server-based

applications manage the LMR channels, and include features such as per-user access, distribution
