Yes, that’s right.

It’s possible with Horizon Call. The world's most bandwidth- efficient mobile VoIP app.

This means it operates over lower-bandwidth 2G technologies as well as 3G, 4G/LTE, WiFi and WiMax – allowing you to target a lot more subscribers with mobile VoIP, while offering a higher quality of service than other solutions.

Enabled by our SmartPacket™ technology, Horizon offers VoIP from only 2kbps compared to around 8kbps from other VoIP services today.

Fully compatible with digital telecommunications standards, it is capable of interconnecting any phone system over IP – on mobile, fixed and satellite

Horizon is a complete end-to-end solution for operators and service providers.

It enables low-bandwidth VoIP based on SmartPacket™ technology via smartphones, PCs, analogue and digital fixed phones.

We provide all the necessary elements for you to build and operate your own Horizon network or we can host the service on your behalf.

Traditional VoIP calls send the same amount of data in both directions, regardless of whether someone is speaking or not.

Horizon is designed to detect silence and send “heartbeats” instead of data, so you know the line hasn’t been dropped.

For mobile satellite.

Save bandwidth.
Save costs.

Controlling costs will always be a concern. Pay-per-megabyte pricing still tends to restrict usage to only the most critical communications. Horizon can help by making best use of the limited bandwidth available and gives the user more control over how much data they consume.

For VSAT.

Your bandwidth.
Work it.

You will always want to make your bandwidth work harder for the same level of spend. Horizon can help by making best use of the bandwidth available, allowing you to make room for other applications.
