Here’s some text from our web site that describes the different players:
Equipment Vendors
Equipment vendors are generally distinguished between pure antenna manufacturers and satellite
equipment manufacturers that produce indoor or outdoor ground equipment including antennas, LNBs,
BUCs, hubs, routers, software and network management systems.
Satellite Operators
Satellite operators are responsible for the planning and cost of the construction and launch of satellite
into space. They own and manage a constellation of satellites and determine coverage and geographic
areas. Satellite operators lease this bandwidth to service providers, government entities, television
broadcasters, enterprises and sometimes direct to the end consumer.
Service Providers/ Network Operators
Service providers, sometimes known as network operators, are telecommunication companies or
specialized satellite service companies who sell a full service package to the end customer. They
lease capacity from satellite operators, purchase and operate the network equipment and the antenna,
and are responsible for the installation and maintenance of the network.
Customers
Customers are the enterprises, organizations and consumers who use satellite communication
services. Governments or large corporate customers may operate as their own service provider by
managing the equipment directly and leasing bandwidth from satellite operators. Individuals and
smaller enterprises typically work with service providers who manage the equipment and connections.
To be clear – iDirect is strictly an equipment vendor – we build the hardware and software in the hub system and remote routers (or modems if you prefer). We also re-sell the other components needed to make a system like antennas, BUCs and LNBs although we don’t manufacture these ‘dumb’ items ourselves. We don’t offer services…
A satellite network provider / operator will buy our gear, rent some ‘space segment’ from the likes of Intelsat, Hispasat etc. and deliver a service to end users – for example a bank or a mobile operator. Sometime mobile operators are themselves satellite network operators for their own private network – this is because mobile backhaul networks are usually pretty large so justify buying a complete hub, and also for security reasons – mobile operators sometimes prefer to keep the backhaul in-house.
A satellite operator will typically just sell MHz of space segment on a particular transponder / satellite to a network provider. The Network Operator will sell capacity in Mbit/s to the end user.
At the hub end (often located with the HQ or main switching site of an operator) they need some rack space for the hub and some servers (typically one 19inch rack is enough) and a large antenna (3m – 7m diameter, depending on a lot of parameters). Sometimes you’ll find the mobile operator has this on their roof or in the car park. Other times they rent capacity at a ‘Teleport’ where someone else has already invested in the antennas etc. and one can either just rent co-location space and install the hub there and connect to an existing antenna. A final model is the VNO model - Virtual Network Operator. In this case someone (including the satellite operator themselves – Intelsat do this a lot) installs both hub antennas and iDirect hubs and in effect rents out slots in the hub so that a third party can run a network without all the capital expense. This is often done to provide start-up facilities to new operators or operators in new territories. Later when they grow they might invest in their own hub.
