![]() The way you're holding your phone, the location of the phone within your home, the load on the nearest cell tower it is connected to, and more can all influence the results. Unlike your home internet connection that (for most folks) is coming over a wire or fiber, to a fixed location in the house and is not particularly vulnerable to outside variables, your phone connection certainly is. Mobile data is a lot fussier due to the nature of the cellular network and your phone's hardware. ![]() If you speed-test your connection at 300 Mbps down and 40 Mbps up, you can run those tests over and over again without a whole lot of variation. Home broadband speed tests are usually fairly consistent. If you're in the middle of downloading updates or uploading backup files, wait for the process to finish. Stop any video streams you're listening to in the background. Stop streaming Spotify or any other audio like podcasts or YouTube Music. After the switch, I could get a strong enough connection to tether multiple devices. Before the switch, I was getting dial-up level speed test results in the area I wanted to remote work. After years and years of using Sprint and then Ting ( an MVNO that used to rely on the Sprint network, but now uses Verizon and T-Mobile networks), I ended up switching to Cricket (an MVNO that uses AT&T networks). The same goes for running the tests at any location you plan to remote work. If not, you might consider a different apartment or switching providers. If you're using your phone as a mobile hotspot, for instance, you'll be much happier if it's in a location where it consistently gets 25 Mbps instead of 2 Mbps.Īnd if you're apartment shopping and rely heavily on your phone's data plan, it would be very wise to run a few speed tests around the location of any apartment you're looking at to ensure your mobile provider delivers a strong signal with high speeds at that location. ![]() You might run a few speed tests in your home to locate the strongest cell signal location. But if you have a room full of guys with their Android phones connected to the same AP, they can "hear" the band is in use and wait for their turn.But there are lots of other reasons to run a speed test now and then on your mobile device, independent of checking to see if you're getting your money's worth. In this case they can both (or several of them) access the AP at the same time causing stalls and resynchronization, not very different from old-school coaxial ethernet collision issues. Wrt several devices taxing the network, it is more pronounced in a near-far case where the clients cannot "hear" each other. But very little real overhead is created by idle clients. ![]() Obviously "often" is in machine terms, to put things into perspective the client Wi-Fi chip has only about 76us to react during a transaction so almost all of the low level functionality is handled in dedicated hardware even for host-based solutions. Longer answer gets a bit involved but basically Wi-Fi physical layer is entirely asynchronous technology and the clients do not "say" anything much "often" unless they want something. The simple answer is: "No, the number of devices connected to an AP have little to no effect if they're not doing anything". I spoke with a person who actually designs Wi-Fi hardware on low level signal processing et al.
