Introduction AP-4000/4000M/4900M User Guide Mesh Networking Mesh Networking Using the ORiNOCO Mesh Creation Protocol (OMCP), the AP-4000/4000M/4900M supports structured Mesh networking. In a Mesh network, access points use their wireless interface as a backhaul to the rest of the network. Access points connected directly to the wired infrastructure are called “Portals;”...

Introduction AP-4000/4000M/4900M User Guide Mesh Networking are discovered, MAP2 through MAP8 will build a neighbor table from the beacons and probe responses they receive. The neighbor table contains three kinds of links: • Active: Link with a Mesh neighbor that has gone through association and authentication, and the port is open. •...
• The maximum number of links downlinks from a Mesh Portal to Mesh APs in the tree is 32. Proxim recommends a maximum of 30-40 APs total per portal (whether connected directly to the Portal or to another Mesh AP) for an average per-client throughput of 300-500 Kbps.
Guidelines for Roaming • Typical voice network cell coverages vary based on environment. Proxim recommends having a site survey done professionally to ensure optimal performance. For professional site surveyors, Ekahau™ Site Survey software is included in the Xtras folder of the Installation CD.
ORiNOCO Enterprise MIB Proxim provides these MIB files on the CD-ROM included with each Access Point. You need to compile one or more of the above MIBs into your SNMP program’s database before you can manage an Access Point using SNMP. See the documentation that came with your SNMP manager for instructions on how to compile MIBs.
Introduction AP-4000/4000M/4900M User Guide Management and Monitoring Capabilities Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word, Notepad, or WordPad. SNMPv3 Secure Management SNMPv3 is based on the existing SNMP framework, but addresses security requirements for device and network management.
Installation and Initialization AP-4000/4000M/4900M User Guide AP-4000/4000M/4900M Hardware Description AP-4000/4000M/4900M Hardware Description Overview The AP-4000 and AP-4000M are tri-mode APs equipped with the following embedded radios: • One embedded 802.11a radio and one embedded 802.11b/g radio, enabling simultaneous support of 802.11a, 802.11b, and 802.11g clients as well as Mesh operation on either the 2.4 or 5.8 GHz band.
When transmitting, the AP chooses the antenna with the highest success rate, and broadcasts are transmitted on alternating antennas. Antenna diversity is enabled by default (set to “auto”) per wireless interface. When using the internal antennas, Proxim recommends leaving antenna diversity enabled. However, you may disable antenna diversity by manually selecting which antenna to use for each wireless interface through the Command Line Interface.
