I don’t usually work in a coffee shop – I don’t like not being able to charge my laptop, and my “home office” is the living room couch, with multiple computers strewn in front of me while I watch sports on TV – but on a recent nice and sunny day, I was convinced to go to one. Unfortunately, technical difficulties abounded. I waited in line, bought a drink and asked for the Wi-Fi password. I spent a few minutes trying to log in to various access points with no success – it turned out that my (brand new) machine could not see the coffee shop’s router.
Luckily, all was not lost. I fired up “Mobile Hotspot” on my LTE phone and, in less than a minute, connected my laptop to the internet using the phone’s software-based “Soft AP.” The only downside? My phone only lets me run “Mobile Hotspot” on Channel 6 in the noisy 2.4 GHz band – I’m sure that’s to prevent some crazy harmonic of the LTE phone transmitter from interacting with the Wi-Fi chip in the phone, but it was certainly inconvenient where I was sitting because there were at least a half-dozen access points set to Channel 6. In fact, I’m pretty sure Channel 6 is the most commonly-used Wi-Fi channel in the United States. So my data rates were in the range of 10 Megabits per second – probably better than I would have had if I had been able to connect to the coffee shop Wi-Fi, but not that great.
You probably know where I’m going: this is one of those times I wish I had 5G WiFi to go with my 4G LTE phone. When I use the internet directly on my phone, I’ve been able to get upwards of 25 Mbps in some places using first-generation LTE. If I had 5G WiFi, I’d have a lot more bandwidth to work with and fewer interferers, so I could get my full LTE data rate on my PC. And future LTE networks will likely offer significantly higher data rates, way more than I got at home with DSL and more than I can get with a cable modem. (I’ll never be able to get fiber to my house, so those are my choices.) In fact, with LTE routers becoming more common, they might become an alternative to cable modems – they take a matter of minutes to set up rather than having to wait for days or weeks for someone to come to your house to install the system!
