Satellite broadband is available to anyone who lives in rural areas where copper wire based broadband services are not yet available. Speeds which used to be poor have recently improved and you can now expect download speeds of up to 20 Mbps on a clear day. Satellite systems are of course available to anyone capable of pointing a satellite dish at a satellite. There are now variants of the technology that allow for two way satellite communication and still some that use dial-up for uplink communication.
Once user allocation and billing has been sorted out the system can be erected fairly quickly as the satellite is geo-stationary (it is always in the same point in the sky) and so the dish must simply be pointed and the appropriate router connected. The system can then be made live without digging any tunnels or programming any underground routers.
Satellite technology is heavily invested in by corporations and goverments alike and the bandwidth and features available will continue to expand without significant change being required to the receiving dish. In the most part just upgrading the router will suffice.
As there is no surveying or planning to be made as there actually is no cabling then the lead-time before installation is substantially less. A dedicated fibre connection cab be scheduled over 90 days in the UK but satellite can be rolled significantly quicker as the system only has to be configured or installed with the ISP satellite allocation team and no land line intervention is required.
Contractually the situation is similar to signing up with any satellite provider of television or other services. Although with the internet there is a bidirectional element to the service the user authentication provided to the user to allow uploading of data can be removed or disabled as simply as with standard broadband.
