The SPEEDLAN 8500 IDUs present a significant breakthrough in LAN connectivity by offering these
high performance IDUs that outperform other wireless spread spectrum systems in the industry. These
IDUs contain full remote SNMP management and security in an affordable package. This enables
you to monitor a number of SPEEDLAN 8500 parameters including RF-signal quality and noise level,
as well as transparent bridging with advanced filtering for security and network reliability.
The SPEEDLAN 8500 IDUs are mounted inside the building and connect to the outdoor antenna

SPEEDLAN 8500 Outdoor Unit (ODU)
The SPEEDLAN 8500 Outdoor Unit (ODU) provides bi-directional frequency (translation) from the
2.4 GHz band to the 5.8 Ghz band. It allows the use of existing WLAN equipment on the 5.8 GHz
band, especially since this band provides relief from the interference which is present on the 2.4
GHz band in many areas. The 5.8 GHz band is also useful for backbone or backhaul use.
All functions of the SPEEDLAN 8500 ODU are transparent to the user, which means no adjustments
are required. Channel assignment and network set-up are both performed at the radio card (or
access point).
