1.4. Applications
The following subsections provide examples of typical WipLL applications.
1.4.1. Broadband Data Access
Using a standard PSTN modem in circuit-switched networks, subscribers are limited
to 56 Kbps of throughput, and in most cases, to 28.8 Kbps. From the operator's
perspective, once a subscriber has dialed up with a PSTN modem, a full channel is
occupied for as long as the session lasts.
WipLL subscribers are limited only by their own configuration, with a maximum of
4 Mbps—70 times faster than the fastest PSTN modem. However, subscribers do
not necessarily consume more bandwidth from the operator, since bandwidth is used
only when a data packet is transmitted.
These characteristics of WipLL make it suitable for providing data access to
subscribers while maintaining best usage of bandwidth and capacity.
