Push-to-Talk over
Cellular/IP (PoC)
Unlike traditional two-way radios that rely on radio frequency (RF) transmissions, PoC is an instant communication device that is based on cellular service and/or Internet networks, incorporating push-to-talk technology into a radio handset to connect users in real time.
PoC allows users to communicate with one or more receivers instantly, in a half-duplex mode, that is, both parties can send and receive information but not at the same time. A data plan SIM card is installed in the PoC device to enable rapid access to cellular service and the Internet.
PoC has emerged as a growing alternative two-way communications system for security applications, largely because of its flexibility for system upgrades and wide range of coverage, but also because of its low capital investment and fast set-up time.
Compared to conventional two-way radio systems, PoC radios provide optimized capabilities for security professionals.
PoC Combined with Radio-as-a-Service (RaaS)
Taking PoC to a higher level of performance can be achieved for security companies by integrating Radio-as-a-Service (RaaS) into a PoC operation.
RaaS is a turnkey solution that provides ongoing management and support for PoC two-way radios. It can include a low monthly fee, maintenance agreement, and scalability to add radios as needed. RaaS can also help reduce downtime by providing timely repairs and upgrades.
RaaS makes it possible for security businesses to shift up-front capital investments to manageable costs using an operating expenditure model. The RaaS model offers more flexibility and options in pricing. While the security business does not own the hardware, they do not have to be concerned with their communications assets becoming obsolete, because they have access to upgrades without incurring additional costs.
