800 kbps upload for your entire shop? Yikes. I get 25/25 reliably, and it's just me and one hunchback.

Our older warehouse complex here in Burnaby, BC (Canada) was just wired up to fiber. We selecting 15/15, but could go to 300/300 for only a bit over double what we are paying...

Tinyurl:

Sale prices in Canadian $, which is around $0.73 on the USD right now. $100CAD = $73USD.

I'd say fiber has an advantage...

MikroTik LHG 60G.

60 GHz WiFi, maxes out at 1Gbps fullduplex due to hardware interface, list price $300 for a pair. Works up to about 1500m (a mile).

Until it rains really hard. That is when the wireless highspeed of a client goes down, completely.

Though I agree, wireless is the future and just about the only option to (re-) crack the old Missy Bell monopolies.

It doesn't rain much here! And the hop is only a few blocks, with a claimed 174 dB margin.

You might want to have their installers come back and...

1) Ground that antenna mast 2) Swap out all those black plastic tie-wraps for something that will last longer than a year or two.

Looks like Microtik 60GHz but I'm not sure. That dish package is available on other frequencies. Also, nice looking installation. I'm jealous: High atmospheric oxygen attenuation at 60GHz:

5G yes, but probably not mesh. Store and forward wireless mesh networks don't work very well and don't scale well for large system. Here's my disorganized notes for a talk I gave on why mesh sucks: My guess(tm) is 5G on 28/39GHz will go to with small cells where you have fabulous performance near the small cell radio, and nothing as you move away from it. The rest is just installing small cell radios wherever possible. That leaves the problem with the backhaul, which will probably be a mix of wireless and fiber:

Best of luck in the new building.

Damn, I missed that.

I had an antenna install fall apart because I used the wrong ty wraps from the local hardware store. So, I switched to genuine UV resistant. No problems so far after about 5 years:

We don't get lightning here.

Doesn't look like a big hazard.

Limited-distance multi-GHz cells allow one fast link, fiber or microwave or whatever, to cover a lot of wireless devices in a modest area, like one city block maybe. That saves a heap of wire and fiber.

We only need one network to do everything: TV, internet, security, phones, iot, talk to cars, control street lights and traffic lights, read meters... everything. This current tangle of wires and fibers and transmitters and cell towers and meter readers is barbaric.

Until everybody does it, and the spill-over from everybody else's links turns into an impossibly high noise level on your link.

Our WiFi from one end of the flat to the other works fine, until all our neighbours get busy. So my wife's computer is now linked to our router by data over the mains wiring.

But everybody using the same microwave frequencies in free space will be even more barbaric.

Cellular networks minimise the problem, but you don't seem to have that.

Wireless runs out of total bandwidth - links interfere with each other. It's great for cases where it's hard to get a cable link of some sort - but it's only great as long as there are few people using them. And it can be affected by the weather.

Our fibre is 500/500 Mbps - regardless of weather, or other customers. If we want up to 10/10 Gbps, they need to blow a new fibre down the tube which is quickly and easily done.

Nice! We have that here on the Isle of Wight (small island off the south coast of England) Population ~140K. Only 150 MBps at the moment...

It's not that far off the south coast. When I was post-doc in Southampton, I played hockey there from time to time, and even took the hovercraft ferry over to the Isle of Wight when I missed the regular ferry.

It was a windy day, and got windier - the hovercraft flipped on the next trip.

Small world eh ? We built fancy Laser Controllers for a spin off company formed by Soton Uni ex grads.... IOW is no match for Sydney :)

The Isle of Wight has its own charms. I grew up in Tasmania, which is rather larger - about the same size as Ireland - but only about three times the population (515,00 versus 140,500).

Not when you make the cell size smaller and smaller. Of course, eventually you have to deal with connecting all those little transceivers but one can pick the locations to make that easiest versus having to trench up a busy street in a large bustling city. In America that would often be on the telco poles.

That sounds easy but only until you show up at city hall trying to get a permit for it. And the permission from law enforcement to block the street. And a deal with the local union guys. And a noise abatement exemption. And an (expensive) attorney to fend off eventual environmental impact complaints and business losses because people can't park in front of Chez Frou-Frou for the day.

isn't there a limit to how small the cells can go?
