Other than the high data rate and
QoS features, HiperLAN2 includes including the following:
• Automatic frequency allocation
• Security support
• Mobility support
• Network and application independent
• Power save mode
Automatic frequency allocation is especially important
because this allows for easy installation without the need for
complicated frequency planning such as that required for cellular.
The access points use a built-in support for automatic
transmission frequency allocation.
HiperLAN2 networks also supports authentication and
encryption. A handoff mechanism is managed by the mobile
terminal based on received signals from each access point.
Connections are maintained just in cellular (hopefully maybe
even better). The HiperLAN2 network may also integrated with
a variety of fixed networks.
A power save mechanism is based on mobile terminal-initiated
negotiation of sleep periods. A request is made to the
access point for a low power state and a specific sleep period.
At the end of the sleep period, the mobile terminal searches for
a wake up indicator from the access point, and in the absence
of that, sleeps the next period, etc.
