My customer plans to extend existing wireless coverage and upgrade to controller based network.
Let me shortly describe the situation based on the attached network map.
RAP points are installed on the buildings, they have wired uplink.
MAP points are installed outdoors (in the IP66 sealed ABB boxes) on the poles (height 5 m), only power is present on the poles, no wired uplink.
Now MAPs (Non root bridges) are connected to RAPs (Root bridges) via 5 GHz interface in bridge mode.
Red points: already installed Autonomous APs, 1242AG model.
Green points: APs planned for installation.
1. In order to upgrage to controller base network I want to install two 2504-25 controllers in failover mode. I have AP-to-LWAPP-Upgrade-Tool and is familiar with the image upgrade procedure. However, I have a question: if I upgrade all existing RAPs and MAPs to LWAPP mode, how the MAPs without wired uplinks will connect to RAPs and then to controller? Should I have physical access to their console port to issue some CLI commands to connect to RAPs?
2. Can 2504 controller be configured for operation in mesh network mode without additional licenses?
3. For network expansion I plan to install 3502E access points in sealed boxes. I chose them due to separate 2.4 and 5 GHz antenna ports, in order to use omni antennas for 2.4 client coverage and 5 GHz directional antennas for wireless uplinks. The distance between APs is abou 100 - 250 meters. Is it recomended to use directional antennas for wireless uplinks or I can take 1602E (or 2602E) access points and dual band omni antennas and install a good working mesh network with 5 GHz uplinks on omni antennas?
4. Can 2504 controller work together with 1242AG, 1602E and 3502E points?
5. How should MAPs be preconfigured to begin working in mesh network after powering them up on the poles on site?
