> Up to 2 Gbps downlink

> 2.5 Gbit/s PoE to upstream switch

Can anybody explain to me why these supposedly premier networking devices are lacking so much in bandwidth? I get it that mmWave is really only ever realistically going to hit 2.5G over the air, but is there any reason why they're not willing to provide at least 10G copper, or an actual SFP port? Hell, even Macs support 10G these days. I never understood this. Do they mean 2 Gbps downlink per client, or per device in total? If it's the former, 2.5G wired seems like a major bottleneck to any serious consumption.

If a single client at 2 Gbps is all the promise of 5G amounted to, well, it would be disappointing to say the least.

This product targets businesses where they will mount it in a fixed position and target a specific tower so they get the best throughput.

Did you read through the press release?

Not GP but I’m trying to figure out what you’re insinuating.

> For tougher environments or deployments with poor indoor cellular coverage, the outdoor model maintains the same high performance cellular connectivity with improved antenna performance in a durable IP67 rated enclosure. It is built for rooftop installs, off site locations, and mobile deployments where reliability is critical. Just like its indoor counterpart, you can also connect it via any PoE port, anywhere on your network, greatly simplifying cabling requirements.

And the first image they show of the outdoor model is it installed in a fixed location on a rooftop.

The fallback support for UniFi setups will be awesome. I’m honestly tempted to get it for my house. My ISP downtime is pretty low but it does happen every once in a while, at the most inopportune times, which impedes working from home. Having a wireless backup would hopefully cover those downtimes

There are now quite a few options for wifi APs with cellular backup. I use TP-Link, and it's ok for the price, I guess, and supports adding OneMesh range extenders.

The problem with this setup for me is that it doesn't work with uplink that sometimes becomes unstable yet nominally working, and in general LTE fallback triggers slowly.

Are there any prosumer-friendly options for connection bundling, which can balance uplinks continuously?

The whole 2.5 G spec is a weird step for ethernet speeds too. It's unfortunate it took off.

I think you answered your own question - also the places where mmWave is available, there is also often other better internet connection options.

They said the same thing about 40G but hey, I've loved it for bridging the gap between my two (10G and 100G, respectively) Mikrotik switches. You can have a dozen Gigabit ports, as well as up to four true 10G devices on your aggregation switch, and neither would be bottlenecked by traffic to and from the backside. This has been a massive boon. However, when it comes to 2.5G, I struggle to find one good reason to use it; such a tiny step-up in bandwidth, and for what?

Portability and heat. You can get a small USB 2.5G adapter that produces negligible heat, but a Thunderbolt 10G adapter is large and produces a substantial amount of heat.

I use 10G at home, but the adapter I throw into my laptop bag is a tiny 2.5G adapter.

These things are nice when they work but when they don't you're completely in the dark. Even figuring out how much GB is left on your simcard is a nightmare.

This is a modem, it itself is the client of a cell tower/base station. So unless you put it in a faraday cage with the base station next to it, 2G is almost certainly enough.

The better reason to put a 10G transceiver in this would be that some (cheap, honestly garbage) SFP+ transceivers can’t negotiate anything between 1G and 10G. But I’ve only seen that on bargain-bin hardware so I don’t know that they should be designing products around it.
