Check mobile hotspot speed before a remote exam

Check hotspot download speed on the computer you will use, compare results with exam requirements, and fix common slowdowns before test day.

If your remote exam will run through a phone hotspot, a strong signal on your phone does not guarantee that the computer will get a reliable connection. Download speed can change with your location, network congestion, and how many devices are using the hotspot.

Test the connection on the same computer, in the same place, and with the same setup you plan to use for the exam. The Speed Test measures download and upload speed, ping, and jitter so you can check more than one number.

Test your hotspot connection

  1. Connect the computer you will use for the exam to your phone's hotspot. Open the Speed Test on that computer, not just on the phone.
  2. Set up the phone and computer where you expect to take the exam. Keep the phone in its usual position, and turn on any VPN or required exam software you will use on test day.
  3. Pause streaming, downloads, cloud backups, and other heavy internet use on the phone and nearby devices. This gives you a useful reading for the exam setup without unnecessary traffic.
  4. Run the speed test and note the download speed, upload speed, ping, and jitter. Download and upload speeds are shown in Mbps, or megabits per second.
  5. Repeat the test two more times, with a short pause between runs. Write down all three results, rather than relying on the single highest reading.

Speed tests exchange test data with our server to measure the connection. If your mobile plan has a data cap, keep the number of runs low because each test uses mobile data.

What the result means

Download speed stays above the exam provider's minimum

This is a good sign for receiving exam pages, images, and video. Check the exam provider's current technical requirements and compare them with all three results. Requirements vary, and a download speed reading alone cannot guarantee that the proctoring service or exam platform will work.

Download speed is good, but upload speed is low

The computer can receive data quickly, but sending your webcam video, microphone audio, or exam responses could be less reliable. Compare upload speed with the provider's requirements too, especially if the exam includes a live proctor or video check.

Ping or jitter is high, or results vary widely

Ping is the time it takes a small request to travel to a server and back. Jitter describes how much that response time varies. High or uneven results can make a live session feel delayed, even when download speed looks adequate. Try the fixes below, then test again. For more checks to prepare the whole connection, see connection planning for a remote exam.

Every run is slow

The hotspot may have a weak mobile data connection, the network may be busy, or your plan may limit hotspot performance. A speed test cannot identify which cause applies on its own, so change one thing at a time and compare again.

How to improve hotspot speed

  1. Move the phone to a better spot. Place it near a window or in an open area, rather than inside a bag, behind a monitor, or under a desk. Keep it close enough to the computer for a steady Wi-Fi connection.
  2. Pause other network use. Stop video streams, app updates, and large file transfers while you test. If other people need the hotspot, test again when they are not using it heavily.
  3. Check that the computer is connected to the phone. On Windows 11, open Settings › Network & internet › Wi-Fi and check the connected network. On a Mac, open System Settings › Wi-Fi. On the phone, check that cellular data and the hotspot are on. On iPhone, use Settings › Personal Hotspot. On many Android phones, use Settings › Network & internet › Hotspot & tethering. Menu names can differ by model.
  4. Try a different hotspot band if your Android phone offers one. A 5 GHz hotspot can work well when the phone and computer are nearby. A 2.4 GHz hotspot can reach farther or work with older devices, though it may be slower. Change one setting, reconnect the computer, then repeat the test. iPhone hotspot options vary and may not include a band selector.
  5. Keep the phone from overheating. Heavy use, direct sunlight, or a case that traps heat can make a phone slow down. Put it on a firm surface out of direct sun. If you charge it during the exam, use a charger and cable that do not make it unusually hot.
  6. Compare another connection method. If your phone and computer support USB tethering, test it as an alternative to hotspot Wi-Fi. Confirm that the exam provider allows it, and use the method you actually plan to use during the exam.
  7. Contact your carrier or plan a backup. If results remain poor in different locations and at different times, ask your carrier whether hotspot service is limited or whether there is a coverage issue. If the exam is important, arrange an allowed backup connection before test day.

Why one speed reading is not enough

Mobile networks share capacity among nearby users, and that load can change during the day. A test done late at night may look better than a test during the exam's scheduled time. If possible, check at the same time of day and from the same room as the exam. A short test is a snapshot, not a promise that the connection will stay unchanged.

Before the exam, follow the provider's own system check and connection instructions. A speed test uses a nearby measurement server, so it cannot confirm that the exam website, proctoring software, or a particular video service will be reachable. Nothing in the speed test checks your exam files or responses.
