802.11B Expansion Pod - Juniper Allegro CE Owner's Manual

802.11b Expansion Pod

An Allegro using the 802.11b
expansion pod offers the
flexibility and benefits of
being connected to a Wireless
Local Area Network (WLAN).
The 802.11b (also referred to
Wi-Fi) is a variant to the
802.11 series that applies to WLAN.
A WLAN is a data communication system used to replace or extend a
wired LAN system. A WLAN system provides additional
functionality by using radio frequency technology to transmit and
receive data over the air, through walls, ceilings, and even cement
structures, without wire cabling.
A WLAN provides all of the benefits and features of established LAN
technologies like Ethernet, but without the limitations of being
attached to a cable. An Allegro using 802.11b provides significantly
increased freedom and flexibility for both data collection applications
and the people collecting the data.
An Allegro using the 802.11b expansion pod with a Cisco Aironet
350 card offers the following features:
• Superior range and throughput
• Indoors: 130 feet (40m) at 11 Mbps and 350 feet (107m) at 1 Mbps
• Outdoors: 800 feet (224m) at 11Mbps and 2000 feet (610m) at 1
Mbps, up to 5000 feet with external antenna on access point
• Secure network communications
• World mode for international roaming and reduced range
The 802.11b provides 11 Mbps data transmission in the 2.4 GHz
band under optimal conditions. Depending on the amount of
surrounding interference such as trees, walls, people, etc., the
transmission rate can fall back to 5.5, 2 or 1 Mbps.
