3.2. Services
3.2.1. Broadband Data Access
Using a standard PSTN modem in circuit-switched networks customers are limited
to 56Kbps of throughput and in most cases to 28.8Kbps.
From the operator's perspective once a customer has dialed with a PSTN modem a
full 128Kbps channel is occupied for as long as the session lasts.
With WipLL customers are limited only by configuration, with a maximum of
4Mbps, 50 times faster than the fastest PSTN modem.
However, they do not necessarily consume more bandwidth from the operator since
bandwidth is used only when there is an actual data packet to transmit. This happens
about 10% of the time.
As a result, assuming the same bandwidth utilization of 128Kbps per customer an
operator may actually commit 128Kbps to each customer, thus over-selling
bandwidth without having any effect on the performance of the connection.
These characteristics of WipLL make it suitable for providing data access to users
while maintaining best usage of bandwidth and capacity.
The following paragraphs discuss some of the services available with the broadband
access that WipLL can offer.
3.2.2. High Speed Internet Access
One of the advantages of WipLL is the fact that users are "always on". This means
that there is no dialing process and no need for the hassle involved with dialup
access. You need only open your web browser or email program to be instantly
connected.
