“Ka capacity will no longer be sold by satellite operators as naked capacity, but rather as managed services. For broadband access networks, the operation of the service by the satellite operator can go very deep in the value chain� than with wide beams, because the power is concentrated on a smaller area. However, this therefore means that to be able to communicate beyond the scope of the spot beam as is required with many applications including broadband access services, it is necessary for the other end of the satellite link to be situated outside of this beam. For obvious practical reasons, access to several spot beams is concentrated into a single transmission/reception location called a gateway and communication with a station in the spot beam is only possible through the gateway. In other words, satellite communication using a spot beam satellite utilises a star configuration, and communication between two remote stations in two different spot beams needs to transit through the gateway.

Because the operation of the gateway includes the careful management of power levels and frequencies among the feeds, spot beams and against fading, it is very likely that most satellite operators will want to operate the gateways themselves. An alternative scenario is for the satellite operator to outsource the operation of its entire gateways to larger independent teleport operators. Hence the impact on the value chain of the satellite business: Ka capacity will no longer be sold by satellite operators as naked capacity, but rather as managed services. For broadband access networks, the operation of the service by the satellite operator can go very deep in the value chain: the market will see some service operators becoming their own satellite operators, while some satellite operators

will venture into the service provider business. Fortunately for independent service operators, the integration does not need to be as pronounced for all applications. The role of teleports will however be very different during the era of spot beam Ka-band services.

What will the applications and impacts be... Professional VSAT Networks: The most obvious business application, after consumer broadband access, is professional and private VSAT networks. Ka-band technology will open the door to very large deployments and therefore the cost of terminals will further go down. The Ka-band satellites also offer higher and cheaper throughput. Because
