DSL Elements DSL transmits data over copper phone lines. Each line is split into two channels - one for voice and fax and the other for computer use. DSL's distance limited feature prohibits some residential and business use since the customer must be located approximately 15,000 feet from a central office. The installation timeframe and cost varies, depending on DSL type and broadband guarantee. And wireless Internet access is vying for attention.
Data travels through the air to base stations that transmit and receive signals.
Each wireless user has an antenna pointed at the base station to pick up and deliver data. Wireless technology doesn't require a phone or cable company for leasing capability, but it is still more expensive than DSL - five percent to 10 percent says Lingren. We have the technology that actually resides in the building itself. From there, we pick up fixed wireless back to our central office. It's more of an industrial strength solution.
