Configuration and Management
Most APs include embedded Web servers that let the systems be configured and managed using any Web browser. That's OK for maybe a dozen or so APs, but there comes a point where you need a more automated management system, usually built around SNMP. Many higher-end vendors provide SNMP support and some offer an SNMP management system. Using a central management system, you can update firmware and software across all networked APs and, by using profiles and groups, configure groups of APs much more efficiently. Some specialized vendors, including AirWave and Wavelink, provide AP management systems that are compatible with multiple vendor products. However, the list of supported products is usually limited. For example, Wavelink supports Cisco, Proxim and Symbol APs. Some vendors include other options for management, including command-line and menu interfaces accessible through telnet or a serial port.
In the end, your biggest concern should always be system availability. Clearly, the level of management sophistication makes a difference in this regard. However, equally important is the overall reliability of the hardware. In general, enterprise-class products will deliver better reliability, but some lower-cost products may perform just as well. Cover yourself by insisting on appropriate references before you sign the purchase order.
