Rate-Adaptive Digital Subscriber Line (RADSL)

RADSL provides more noise-tolerant and signal-loss-tolerant service than ADSL

Rate-Adaptive Digital Subscriber Line (RADSL) is a DSL technology akin to ADSL (Asymmetric Digital Subscriber Line) in that both feature more download bandwidth than upload bandwidth. RDSL is an improvement on ADSL technology, however, because with RADSL service, customers will enjoy more consistent download speeds in the event of line noise. To achieve this, RADSL equipment automatically trades some upload bandwidth for additional download bandwidth when noise is present between the telephone exchange and the modem.

The improvements that rate adaptive digital subscriber technology offers in noise tolerance and signal loss tolerance also result in greater achievable transmission distances. Consequently, rate adaptive DSL and business RADSL providers are able to provide service to many suburban homes and businesses that they could not reach using ADSL. With RADSL broadband, subscribers who are closer to the exchange experience higher capacities, with those who are further away receive lower rates. When considering RADSL, follow this blueprint:

1. Find an RADSL provider in your area that offers competitive pricing and terms.

2. Find good quality RADSL modems and routers.

3. Find an RADSL service provider that offers 24-hour customer service.

Find a competitively priced business RADSL provider

Prices vary greatly for DSL service. Sign up with a service that offers discounted service for the first month or two and a competitive price thereafter.

Find dependable, good quality RADSL equipment

When setting up Internet access components, a modem is necessary to connect a computer or a router to a DSL phone line in order to access the DSL service. It is common to connect a group of equipment together, e.g. multiple computers to share the access to the Internet. In this case, the unit is termed a DSL router.

For many businesses, it is essential to be able to contact a live person for account help or for technical assistance any time of day. Many providers offer service around the clock.

• Cable's lower cost and simplicity is better for home Internet users. But small businesses will prefer rate adaptive DSL because of its higher speed, guaranteed performance and security.
