The Aironet ARLAN 640 is an advanced learning bridge that is capable of data rates up to 2 Mbps. It is fully configurable and will learn over time which addresses require forwarding and which don't. The ARLAN operates at 2.4 MHz and operates using a half duplex channel. At 100 mWatts the ARLAN has an approximate range of 1000 feet outdoors with line of sight. If used indoors it is capable of ranges from 100 to 200 feet depending on building material etc. 

The Windata AirPort II is a fully 802.3 compatible bridge that offers an aggregate data rate of 16 Mbps with a user data throughput of 5.7 Mbps. Two seperate channels are used for upstream and downstream traffic, one at 2.4 GHz and one at 5.8 GHz. It is capable of acting in a point to point mode, or a point to multi-point mode. With a range of close to 1 mile this is the lab's longest range and highest speed bridge. WPI has deployed a number of these bridges to connect off campus fraternities to the campus backbone. The CWINS lab's bridge is used for performance evaluation purposes.

The Motorola Altair Bridge is one of the most unique products in the CWINS lab'e inventory. Intended as a wireless network connector to link computers and printers with each other, it works just as well as a point to point bridge. At an operating frequency of 19 Ghz the Altair causes no interference in the lower ISM bands where most of the other bridges and network adapters operate. It can support 3.3 Mbps of data bandwidth which is more than enough to support a 2 Mbps Wireless Access Point at the other end. The lab's Altair is currently being used to provide wireless coverage to the campus's Computer Science Building. 

The Solectek AIRLAN bridge provides a bandwidth of 2 Mbps using a spread spectrum signal in the 915 MHz ISM band. The output power of 250 mW is sufficient to provide a link of several thousand feet. Despite the fact that is uses the same frequencies as the Digital RoamAbout card, interference in minimized due to the fact that the bridge uses a directional yagi antenna placed on the roof of the building, so very power is projected into the building itself. This very reliable bridge is being used to connect the Electrical Engineering Building with the campus's Library.

The Persoft Intersect Bridge is similar to the Solectek bridge described above both in terms of technology and performance. 2 Mbps is supported by a radio operationg in the 915 MHz ISM band. The bridge is fully configurable and has learning table capability for enhanced performance. The CWINS lab's Persoft Bridge connects a wireless subnet in the campus's Physic's department to the wired backbone in the Electrical Engineering Department.
