Filtering out the Cacophony of WiFi Networks in Crowded Retail Spaces

In the bustling corridors of a busy retail environment, the struggle for capturing customer attention is mirrored in an often-overlooked aspect of business operations: WiFi network design. As each store sets up its own internet connection with unique equipment and configurations, the airwaves become akin to a crowded marketplace where everyone is shouting to be heard. This results in a cacophony of conflicting networks, creating a dense forest of digital noise that can disrupt your business’s connectivity and customer satisfaction.

Understanding the Wireless Battlefield

Wi-Fi Calculator from Ubiquiti

Check out this new tool from Ubiquiti that can help you see the effects on throughput for different devices. It’s at http://wifi.ui.com

How it works. There are five variables on the tool that will let you see what the expected throughput is for a client device.

First, you can change Access Points and leave everything else static. At the high end you can use the U7 Pro and see that you can get up to 2.16 Gbps. On the other end of the spectrum, you have the Swiss Army Knife coming in at 300Mbps.

Second, you can see what effect channel usage would have on throughput. For example, I can set the AP to U7 and use a Wi-Fi 6 adapter and with zero channel usage I can see that I can get 1.8Gbps.

But with 20% Channel Utilization the throughput drops to 900Mbps.

I can also see the effect of Channel Width, different client devices, and the effect of distance away from the AP. Look what happens to throughput when I move away from the AP. I move from 900Mbps to 540Mbps at a mere 10 meters away from the AP.

It’s a good lesson to see what happens with different channel widths and distances, and what effect different APs have on throughput. Give it a spin if you are interested in understanding how APs work.

TLDR: Like the camera, hate the installation hardware

Coming out of the box, the G5 Turret looks nice. I like the form factor and how small it is compared to a bullet camera. This is definitely a good form factor for Ubiquiti, and I can see this being used in a lot of areas.

I decided to install it outside my front porch, to replace a G4 bullet that didn’t quite have the field of view I wanted. The camera would be under an eave, about 8 feet off the ground, facing north.

First problem: cheap screws. This is an outdoor rated camera, and I can see homeowners installing this in much the same way I am. Most people have aluminum flashing on their homes, and the screws that come with this are woefully insufficient.

They don’t fit a standard #2 Phillips Driver

See how little the #2 driver penetrates the screw? Now, compare this to a self-tapping screw I normally use to install outdoor items:

Notice how this screw has a WAYY better fit then the screw Ubiquiti used. This makes it far less likely to strip. Stripped screws make me swear a lot. Nobody needs to hear the swear words I make up when standing at the top of a ladder with a storm approaching trying to get this camera installed expeditiously. Use better screws.

Second problem: the installation ring. Someone made the smart move and allowed an access hatch for the camera’s cord so it can be mounted flush to a surface. Good move! The BAD part is this is on the piece that detaches from the camera. When you install it, you have to use one hand to hold circular piece to the side of your house, a second hand to hold the drill and put in the screw, and a third hand to hold the camera so it doesn’t bounce around.

I don’t have three hands…we don’t have that much radiation present here to cause that. I improvised by putting in one screw, then putting the camera cord in the slot, holding the ring against the house and then installing the other screws. Since I used self tapping screws, this isn’t a huge problem, but if you used the crappy screws provided…you would invent more swear words.

A better way to do this would be to have the slot on the camera body. That way, you can install the camera ring using your God-given two hands, then set down your drill and pop the camera on. Doesn’t require a third hand, and if you have a hard time with the screws, you don’t risk dropping the camera.

The other problem: the pre-built cord. This is a good and bad, depending on the use case:

• If I was installing this in a new location, I like this cord because its long enough to push through a standard wall. I can then connect/disconnect the camera on the inside without messing with anything on the outside.
• If I am installing this as a renovation, I DON’T like this. Look at the picture above: I already have a cord. Now I have to hide this extra long cord in the vinyl siding somewhere. Not quite swearing level, but still a pain.
• Also, what if you have thick walls? I installed cameras on a church where I had to use a 36″ drill bit to get through the wall. This camera would require me to drill a wider hole to fit the ethernet connector. Might be a deal breaker.

I think overall you’re better off without the cord. Any installer worth their salt can make a short cord. Even better, replacing the cord with just a port (like every other Ubiquiti camera) makes it way easier to rotate the camera, which is a huge advantage over other camera form factors. In fact, if you cut the cord, you could leave the slot for the ethernet cord on the ring that detaches from the camera and install it pretty easily.

See that frown? That’s how I felt installing this camera.

Onto camera performance. It’s a bit of a mixed bag.

• I like the wide angle! I can capture the walkup to my home very easily. In a plant or assembly line, this wide angle is perfect.
• It was easy to adjust. Might want to say on the box/instructions that the blue LED marks the top of the camera.
• Forego the Ubiquiti logos? Mine are sideways. Probably no way to keep them right side up unless you send Ubiquiti stickers.
• The quality of the video recording is OK. There is a HUGE difference between 30 FPS and the 50 FPS from a G4 Pro. 30 FPS is good enough for most things though.
• Microphone is OK, somewhat muted, but not a deal breaker.
• The camera has a hard time detecting kids. I had my son drive his jeep around a bit to trigger the camera. I ended up turning on motion detections just to get it to trigger. If he was close to the camera it would pick him up as a person, but farther away and the camera couldn’t pick him up.

You can see the difference between a G4 Bullet, G4 Doorbell, G5 Turret and G4 Pro in the attached videos of my son. I also attached the standard “hand wave” videos for a G4 Bullet, G5 Turret, AI Bullet and G4 Pro, all about the same height and distance.

Overall, good camera with a lot of use cases, but the following would have to be addressed:

• Recommend an ethernet port instead of the cord.
• If you don’t remove the cord, put the slot for the ethernet on the camera itself, or some way to make it easier to mount on the side of a building.
• Get better screws that are self-tapping, so you can drill into aluminum siding/flashing.
• Figure out how to detect children better. Especially in residential or child care settings, this is a must.

UMR In-Depth Review

The Unifi Mobility Router is a very undersold, yet very useful, piece of equipment. If Ubiquiti negotiated a better deal from AT&T, it would be a game changing device.

I picked up a UMR on a whim because I’m a Unifi addict and I have to try something new.

Elmo gets it. Sometimes you just need the hit of opening a new Ubiquiti product.

Anyway, I wanted to use it when I taught Ubiquiti classes, as the ethernet ports in the hotels we teach at often don’t work or the guest network doesn’t like wired connections, so it’s hard to get a reliable WAN connection for the router the students are setting up. I quickly realized that some students would stream a ton of media “just because,” so after using up my data in one day, I decided that wasn’t going to work. I went to AT&T’s website, but I couldn’t find a useful unlimited data plan. After trying in vain, I put the UMR on a shelf, never to see the light of day.

Then my wife complained that the WiFi at our kid’s ballet studio was terrible. I gave her the UMR, plugged it into the USB port in our car, and voila! Her work laptop had a solid internet connection. She didn’t use a lot of data, so the UMR became hers for a few months with a 5 GB/month plan.

After a few updates and a few months later, I checked out the UMR interface and realized Ubiquiti had packed this little guy with a lot more capability. I also decided to shift my AT&T phones to a business plan instead of the residential plan…and that’s when I struck gold.

AT&T Business Plans will let you have a tablet SIM that has unlimited data. The cost varies depending on the kind of business plan you get. So I shifted all of my phones and three Ubiquiti devices (two UMRs and the LTE Backup Pro) to AT&T Business. The unlimited data tablet plan was ~$50/month and two 15GB/month plans each cost $20/month. Not bad, and definitely cheaper than the plans Ubiquiti offers with the devices. I also think the AT&T gal at the store wasn’t as familiar with promotions, so once I get my first bill I plan to call them to find a better fit.

I used WiFiMan to speed test my UMR. I can consistently get around 25-30 MBps down, which is good enough to stream some YouTube or conduct a Zoom call.

But there was more!                                                                                                                       

I discovered you can setup WireGuard VPN. So I created a WireGuard VPN on my home UdM Pro router, then created a client and uploaded the file in the UMR. One click later and my UMR now automatically VPNs to home, allowing me to access my NAS while on the go. Even better, this means my wife can access the NAS through the mapped drives on her laptop, so she doesn’t have to do anything different.                                                                                                                                                                                             

The connection is way more stable than the 5G on my phone when I’m driving in farm country. I’ve noticed a huge difference when I use my phone on a Zoom call and I’m out in the country. The connection is far more stable and I don’t drop calls like I did before.

PoE passthrough was another cool feature. I powered the UMR with a PoE+ adapter, then turned on PoE passthrough and hooked up a Ubiquiti Touch Phone that was set to Teleport home. Phone worked without any issue. This was really useful when I wanted to demonstrate how a Ubiquiti phone worked for a client.

Now, I didn’t like a few things. Ubiquiti charging for “Mobility Cloud” features is kinda lame, and if you don’t pay the $2/month, you lose the VPN access. The AT&T plans they have are garbage compared to what you get through AT&T business. The best thing Ubiquiti could do would be to negotiate a 5, 20 and unlimited data plan that includes “mobility cloud” and is on-par with AT&T business. If the unlimited was reasonably priced, this could easily replace the T-Mobile 5G routers that are popping up in the rural parts of America. Those routers suck, you can’t disable the onboard WiFi and they don’t get great signal in my experience.

The UMR doesn’t currently have Teleport, although WireGuard seems just fine for what I need.

There are cheaper devices that turn LTE into corded internet, but combined with the VPN and PoE Passthrough, the UMR is well worth the $200 investment. If Ubiquiti negotiated a better deal with AT&T, they would have a great travel/RV/rural router that would easily beat other competitors.

Teaching the UniFi Full Stack Class

wifi-U has started teaching the new UniFi Full Stack class. This is a great class to get to know the new UniFi applications.

The class starts with a review of new equipment that Ubiquiti has introduced. Some of the equipment includes the Express and Ultra lines, the new Wi-Fi 7 Aps and the Pro Max Switches with Etherlighting and the new Intercom systems.

In the class, each student receives a loaner Cloud Gateway; either a UDR, UX, or an Ultra to familiarize with the interface.

In the USFP we talk about the Protect solution for cameras and the Door Access solution. We built these cool boards so we can demo how the products work.

We also go over the Talk product line and how to get phones up and running and how to route calls, make video calls, and use the intercom. We also show the apps that run on the phone like Protect, and Door Access.
