Having things physically closer usually results in better average SNR, meaning higher speeds for everything on the channel.Īlso, as others have mentioned 5GHz might make it through a wall without a lot of stuff in it, but its not going to penetrate very well through several walls. Also, your device may show it has good signal strength but it might be poor quality (bad SNR) so in reality its a poor link speed. I can have several devices running at several hundred megabits of quality, but a single device being really slow bogs down the channel and suddenly everything else starts getting lots of jitter and overall poor network performance despite most devices having good signal quality. One important thing to think about when planning your WiFi deployment is if you have things that have poor connectivity, everything on that channel suffers. Because I now have two AP's running on different channels I've effectively doubled my network throughput overall. I run them at lower power so I don't have an excessive amount of RF blasting into neighbor's homes, but I still get good signal quality to/from each AP. These AP's being in the hallways on opposite sides of my home. I run two AP's hard wired to the PoE switch in my closet. It resulted in the elimination of almost all guest complaints about the wireless network. I have noticed an huge increase in quality and snappiness of FaceTime and other high up and down bandwidth activities once I added more access points so that connections are going through only 2 or 3 walls.įor another reference, I have a hotel that needed to upgrade its network to meet the brand standards for signal strength in all the rooms, and we had to end up installing 6 access points in the drop ceiling of each hallway 15 guest rooms in length (each guest room is ~15ft wide, so the corridor was ~225ft long). Second problem is can the mobile device you’re using return that signal through all those walls to the access point. Even 2.4GHz is considerably slowed by 2 or 3 drywall/plywood obstructions. That’s not my experience, all the way from Meraki enterprise access points to the standard consumer WRT54GL.įirst problem is 5GHz is terrible at going through walls, I don’t believe it will even go through a single brick wall and maintain decent bandwidth.
