Cable modems are the cable television companies' answer to high speed data access. But there are a few inherent problems with the approach. A local loop of fiber cable must be available in your neighborhood. To make the service available to more people, the cable companies must run inordinate amounts of new fiber. A task that is both hugely expensive and time-consuming.
Performance suffers as more people are connected.
As more and more of your neighbors connect and surf the Web, your bandwidth or line speed diminishes proportionately. Security is an issue. Your connected neighbors will be able to intercept your credit card or other sensitive, confidential company data at will. So if availability of service, speed or security are not concerns of yours, this service may work well for you.
