Meru Access Point Features Chapter 1 About Meru Access Points The Meru Access Point radio devices communicate with the Meru Controller and form the Wireless LAN (WLAN). The Meru Controller and Access Points connect to the site’s wired LAN through wired switches. Wireless clients associate with the Access Points as they roam throughout the WLAN. As such, the Meru WLAN is an extension of the wired LAN, providing the wireless benefits of client mobility, enhanced access, and dynamic network configuration.
Meru Access Point Models end-to-end QoS. Meru Access points deliver a 5-fold increase in voice carrying capacity from the current 5-8 calls per access point to over 30 calls per Meru Access Point with no change to the 802.11 client. z Over five times the scalability of alternate Access Points Meru Access Points are unique in their ability to dramatically increase performance over alternate APs, even as client density increases. Meru Access Points, can serve over 100 standard 802.
Meru Access Point Models 00 00109 AP2 Figure 2: AP200 00134 The Meru Access Point 100 family (referred to hereafter as the AP100, unless specifically referring to the AP100-P) consists of the non-plenum AP100 and plenum-rated AP100-P. Both models that conform to the specifications provided by the IEEE 802.11b protocol and work with all standard WiFi clients. The AP100 also serves as an RF monitor to the Meru controller and provides real-time status of RF activity to optimize the wireless network.
