I am working on wireless network design for guest (Aruba) and staff(Cisco) network with below details.
- Introduction to wireless setup:
- The wireless network comprise of Staff network (Cisco Aps) and Guest network (Aruba Aps).
- Around 7 Aps per floor for guest and staff network
- Guest network Site survey/AP location: similar like Staff network
- Guest and Staff network APs are around 2 to 3 meters away from each other
- Risks
- We are concerned about the noise and channel interface
- Due to building regulation, it is not easy to relocate the Access Points
- unfortunately the equipment is already procured, cabling and AP mounting is already done and Guest/Staff APs are around 2 to 3 meter away from each other
- Solution
We need to find solution from configuration point of view. Please check which solution is valid and recommend another solution if needed.
- Solution option1 (Automatic Dynamic Channel Assignment)
- I assume that controllers are intelligent devices and both Aruba and Cisco controller will manage the channel interference. Controllers will change the channels if there is any interference.
- Solution option2 (Distribute channels between Aruba and Cisco network):
- Cisco/Staff will use 3 channels 1, 6 and 11 in 2.4 GH band for wireless AP transmission. Aruba/Guest will be using other overlapping channels (from 1 to 14. except 1, 6 and 11)
- Cisco/Staff will use channels in UNII1(36, 40, 44 and 48) and UNII-3(149, 153, 157 and 161) 5 GH band for wireless AP transmission. Aruba/Guest will be using UNII2 channels in 5 GH.
@experts; please confirm if this is valid approach and has no drawbacks or limitations
- Solution option3 (propose any other best practice solution):
Please also provide other best practices that should be considered in the design.
