On Air · Bonded Cellular · Outside Broadcast

The crowd fills the stadium.
The network fills up too.
Your feed stays live.

Zentari bonds multiple SIMs across different networks so your uplink doesn't depend on any single carrier having bandwidth to spare. When 80,000 fans are all on their phones, your broadcast isn't competing with them.

Why Bonded Cellular

Satellite was the only option. Now it isn't.

Traditional Satellite (BGAN/VSAT)
The old way
500ms+ latency
Geostationary orbit round-trip makes real-time contribution feel sluggish and rules out two-way IFB.
High per-minute cost
BGAN airtime is expensive. A full-day sporting event can run to four figures in comms costs alone.
Heavy, specialist kit
VSAT dishes need pointing, clear sky view, and a vehicle to carry them. Not suited to fast-moving news or roving cameras.
Single uplink path
If the satellite link degrades — weather, obstruction, beam capacity — you have no fallback.
Zentari Bonded Cellular
The modern approach
Sub-50ms latency
4G/5G round-trips are fast enough for real-time contribution, remote commentary and two-way IFB communication.
Pay only for data used
No per-minute airtime. Activate SIMs for the shoot, pool usage across your whole equipment inventory, deactivate when you wrap.
Fits in a camera bag
A multi-SIM bonding encoder is the size of a laptop. Journalists and roving cameras can go anywhere without a satellite vehicle.
Redundancy built in
If one network gets congested, the bonding algorithm shifts load to the others automatically. No single point of failure.
Broadcast Environments

Where our SIMs go on air.

From 90,000-seat stadiums to a journalist filing from a pavement — the same SIM estate handles every production format.

Live sports broadcast
LIVE

Sports & Live Events

Bonded uplinks from pitchside, stadium rooftops and roving ENG cameras. Aggregated bandwidth handles HD and 4K simultaneously.

News gathering
LIVE

News & ENG

Breaking news from anywhere. A reporter with a bonding encoder in a backpack can go live from a pavement, a courtroom steps, or a disaster zone.

Concert live stream
LIVE

Entertainment & Music

Festivals and arena shows pack cellular networks. Multi-network bonding bypasses congestion on any single carrier to deliver uninterrupted streams to millions.

Corporate broadcast
STREAMING

Corporate & Remote Studio

Investor days, product launches, remote presenter links. Studio-quality contribution from locations where fixed broadband isn't an option.

How Production Teams Use Zentari

From recce to wrap in three steps.

1

Pre-provision your SIM kit

Order a SIM set for your encoder inventory in advance. SIMs arrive dormant — no charges until you activate them. Before a shoot, activate the SIMs assigned to that production from the Axis Portal or via API from your scheduling system.

Axis Portal action
Activate 4× SIMs — Production #2847
2

Go live from any location

Insert SIMs into your bonding encoder. The device aggregates bandwidth across all four networks simultaneously, letting you push your contribution feed directly to your cloud ingest point or broadcast facility over the private APN — compatible with all major bonding encoders.

Deactivate when you wrap

At the end of the shoot, deactivate the SIM set from the portal. You stop paying immediately. The SIMs return to your inventory ready for the next production — no contracts to cancel, no minimum terms to worry about.
