Wi-Fi Array
Configuring the Wi-Fi Array 263
11. Max Phones per IAP: This option allows you to control the maximum
number of phones that are allowed per IAP. The default is set to a
maximum of 16 but you can reduce this number, as desired. Enter a value
in this field between 0 (no phones allowed) and 16.
12. Block Intra-Station Traffic: This option allows you to block or allow
traffic between wireless clients that are associated to the Array. Choose
either Yes (to block traffic) or No (to allow traffic).
13. Allow Over Air Management: Choose Yes to enable management of the
Array via the IAPs, or choose No (recommended) to disable this feature.
Advanced Traffic Optimization
14. Broadcast Rates: This option changes the rates of broadcast traffic sent by
the Array (including beacons). When set to Optimized, each broadcast or
multicast packet that is transmitted on each radio is sent at the lowest
transmit rate used by any client associated to that radio at that time. This
results in each IAP broadcasting at the highest Array TX data rate that can
be heard by all associated stations, thus improving system performance.
The rate is determined dynamically to ensure the best broadcast/
multicast performance possible. The benefit is dramatic. Consider a
properly designed network (one that has -70db or better everywhere),
where virtually every client should have a 54Mbps connection. In this
case, broadcasts and multicasts will all go out at 54Mbps vs. the standard
rate. This means that with broadcast rate optimization on, broadcasts and
multicasts use between 2% and 10% of the bandwidth that they would in
Standard mode.
When set to Standard (the default), broadcasts are sent out at the lowest
basic rate only—6 Mbps for 5GHz clients, or 1 Mbps for 2.4GHz clients.
The option you select here is applied to all IAPs.
