Key Features of Horizon
Nationwide Coverage

HORIZON leverages 4G/5G/LTE and Wi-Fi networks to provide secure and instant nationwide radio communications.

Most Reliable PoC System Available

Advanced cloud servers provide the most reliable nationwide PoC services with geographically diverse cloud server redundancy and resiliency for the highest level of service availability

Group and Individual Calling

HORIZON features instant one-to-one (individual) calls, or one-to-many (group) calls to different groups. Quickly build dynamic call groups with a simple list selection or geographically by selecting an area on the dispatch map

Unlimited Channels and Bandwidth

The HORIZON PoC platform allows any number of virtual channels and as many call groups as required. LTE networks also support bandwidth-hungry applications like user-initiated video calling.

No Infrastructure Required

No need to purchase, operate, and maintain traditional radio network infrastructure, and there are no expenses related to owning radio equipment or FCC frequency licenses.

Rapid Deployments

PoC systems are very quickly deployed because the radio network infrastructure already exists, and PoC radios work out-of-the-box with SIM cards pre-installed.

Security and Privacy

Optional ARC4 and AES 128/256 encryption provides secure and private end-to-end calling

GPS Location Tracking

PoC devices with integrated GPS enable fleet location tracking of driver locations and travel routes with time stamps using the HORIZON Dispatch application.

Call Recording

Supports recording group calls as .wav files on the devices to capture call content and playback on PC to retrieve and document action items, instructions, and other important call information

Safety Features

HORIZON supports sending and receiving Emergency Alarms for enhanced worker safety, and the dispatcher can remotely monitor audio and video during emergency situations.
