and managed within Omada controller in the same way as wired EAPs. Meanwhile, because of the ability to self-organize and self-configure, mesh also can efficiently reduce the configuration overhead. Note •• Only EAP225-Outdoor with specific firmware (version 1.3 or above) is available for mesh function currently. •• Only the EAPs in the same site can establish a mesh network. To understand how mesh can be used, the following terms used in Omada Controller will be introduced: ■■ Root AP: The AP is managed by Omada Controller with a wired data connection that can be configured to relay data to and from mesh APs (Downlink AP). ■■ Isolated AP: When the EAP which has been managed before by Omada Controller connects to the network wirelessly and cannot reach the gateway, it goes into the Isolated state. ■■ Mesh AP: An isolated AP will be mesh AP after establishing a wireless connection to the AP with network access. ■■ Uplink AP/Downlink AP: Among mesh APs, the AP that offers the wireless connection for other APs is Uplink AP. A Root AP or an intermediate AP can be the Uplink AP. And the AP that connects to the Uplink AP is called Downlink AP. An uplink AP can offer direct wireless connection for 4 Downlink APs at most. ■■ Wireless Uplink: The action that a Downlink AP connects to the uplink AP. ■■ Hops: In a deployment that uses a root AP and more than one level of wireless uplink with intermediate APs, the uplink tiers can be referred to by root, first hop, second hop and so on. The hops cannot be more than 3. In a basic mesh network as shown below, there is a root AP that is connected by Ethernet cable, while other isolated APs have no wired data connection. Mesh allows the isolated APs to communicate with pre-configured root AP on the network. Once powered up, factory default or unadopted EAPs can sense the EAP in range and make itself available for adoption within the Omada controller. 49
