The Welsh government has an incentive scheme to provide wireless broadband for those with less than 2Mb/s speeds.
The You can claim up to £1000 towards the cost of installing a broadband solution that can provide faster than 2Mbps via the Welsh government’s Broadband Support Scheme. The application form is available here. Such solutions are satellite broadband, and a current provider of this is Avonline Broadband.
One thing to bear in mind with satellite broadband is the time it takes for signals to reach the earth from space. This can cause a bit of extra lag, when looking at webpages, for example. However, for services such as BBC iPlayer, and streaming, or large file downloads, the speeds will be very good. Another solution by the same company uses a special roof aerial.
