The maximum speed is around 400Kbps, although this depends on how heavily the satellite is being used. Cable Perhaps the most tantalising possibility for high-speed data access lies with the cable modem. Established technology combined with high-speed wired infrastructure independent of the telephone companies means that cable modems operating at up to 10Mbps should be both cheap and easy to use. The problems are that cable companies haven't seen the potential in this level of data service, and have been reluctant to invest in the infrastructure to support users accessing the Internet at this sort of speed. Users in the US report that the technology works well, although there have been some security issues as everyone served by the same leaf of the network can access the shared channels used for data transfer.
Suitable encryption solves the problem.
