Whatever they are doing certainly doesn't seem to be making things worse.
I think "5G" is just a fancy wrapper for "we are going to upgrade our networks at a cost of billions of dollars - just like we always do - but we need to make it sound a bit shiner to the investors or they will balk". Combine with clever accounting on the earnings reports (i.e. attribute as much to "5G" as possible) and everyone is happily deceived.
when 5G is available, but weak (or saturated?), my data performance drops off dramatically; my iPhone doesn't fail down, but keeps trying the 5G path even when it's not performing.
(I've also had this problem at the edge of WiFi range; data keeps trying to route over very low bitrate or packet-lossy WiFi... but if I turn off WiFi entirely, boom.)
What actually happens to a TCP connection when you go from 5G to LTE and back?
Technological progress too often is based upon what will increase profit for shareholder driven companies, rather than for adding real value and simplifying lives of the consumers it was meant to serve.
There is a plateau for how much shareholder driven technology can sustain itself, and that ends exactly where consumers are no longer eagerly driven to buy new consumer products and services. It is being demonstrated a lot lately as despite many sites having an astronomical number of users, many of them rarely log in. It's time for companies to start paying attention to alternate metrics to drive their business models than just subscriptions, market investment, and net profit. Pricing and reliability will likely be the most competitive points in economies like this.
So people will usually get Sub-6Ghz 5G on their phones, which is only marginally faster than current LTE and now we have the source of disappointment here.
As I see it, sales people were selling mmWave speeds, without realizing that it is not going to work for most of their customer.
Oh I do. I can grab my laptop, sit anywhere, grab my phone and setup a hotspot, and work away without any concern.
If 5G coverage was better, I would drop my gigabit internet provider right now.
Many of us want higher speeds for IoT projects.
Most carriers haven't switched all services yet, sms haven't converted from 4g to 5g; some phone call processes haven't. If phones have to be connected to both 4g and 5g few of the benefits will be fully seen yet (congestion, battery life, coverage)
TMobile relaunched mobile broadband as a high-speed service, t-mobile announced a wireless video service.
During the setup for the home internet, they were very particular about where to place the device for line of sight to the tower. It consistently gets 1Gbps down and 300Mbps when in 5G UWB mode. There are rare situations in which it falls back an LTE connection that is somehow unimaginably worse than phone tethering.
On the other hand, when I'm using my phone, it'll sometimes _think_ it has the ability to do ultra wideband, but it doesn't work, and the icon disappears and suddenly I'm back on ordinary 5G again with a bit of a hiccup that you note. If I ensure that my phone has clear line of sight to the base station, and confirm that it is using UWB, then I can get similar speeds and latency to the 5G home internet device.
The ultra wideband mode is very sensitive to where you are in relation to the base station, so on a phone moving around your house it may be inconvenient or frustrating to have your phone attempt to use it.
Branding 5G as the next best thing since sliced bread benefits the first 90% of the business as idiots flock to them with their wallets open. By the time they realise what 5G really is, it's too late and they would've already parted with their money (whether onto new handsets/plans for consumers, or various IoT-related things for businesses).
The most important use case was to add additional capacity in dense urban areas. Or like, Stadiums where 100k phones can all sap the network at once.
There are a few flavors but I’m assuming you meant mmWave. The telco I work for has only deployed mmWave 5g in Stadiums in my city and similar large cities. We have deployed Low Band 5g “nationwide” and it’s only 20% faster than LTE. Mid Band 5g has only been deployed in select cities in 2022.
*disclaimer: I’m not a RAN engineer. I googled all of the info above.
They promised for the highest bandwidth bands, and gave us the lowest tier.
4G (what the Long Term Evolution was supposed to reach) has a limit of 1Gbps [1]. I don't think I ever got a 1G speed on a 4G/LTE phone. I have no doubt that 5G will be faster than 4G just as I have no doubt it won't meet any marketing promise.

Guess who's vertical, untethered enough to do that...?
