OK, I've posted before. I bought for a place at the seaside Engenius products, but I'm facing now some problem. I'm having limitations on where I can put the AP. The seller said that he's doing surveys with phones and this is the best way to make planning. So, I installed in another hotel EWS310AP and kinda did the expected work. I don't really have experience but I've got CCNA certificate. Best way to place such AP is in the rooms - no way it should be done in the corridor, because of the bathrooms. 2.4GHz on almost every place is good except of couple places. Don't know about 5GHz spectrum, I must check it everywhere and as the seller told me I must adjust the dBms. There are groups of rooms which will need lower dBm, there are groups which will need higher dBm. Somehow I will figure out how to do this at myself. Many walls are concrete with metal. OK, now I need some advice on coverage of 1000-1500 sq.m. On this place (seaside) there is installed Ubiquity Nanostation M2. I'm currently struggling to replace it with Engenius model - EWS660AP which is omnidirectional and EWS860AP which is 3 times expensive that 660 and has sector antenna. Nanostation M2 has dual polarized antenna and has 0.8km range as seen in their menu. OK, Ubiquity AP can't be added to the Engenius controller to make some features like roaming to happen. But I see modes like AP repeater. Ubqty got it's own SSID and Engenius neutron system got another SSID and settings. Question here is how to make them work together? Thank you.
