I recently had an ISP service interruption at home, leaving me without a working Internet connection for a few hours. I used my iPhone to tether into my 3G connection, did a few speed tests, and wondered how it compared to my regular (cable modem) internet connection. Here are the test results.
I tested my connection speed using only two websites (linked in Sources). I have also run a few iPhone apps that are freely downloadable: Speedtest by Xtreme Labs, SpeedTest.net, CISCO GIST Speed Test and CheckTubes. Of all, Ookla’s Speedtest.net had the best interface and most consistent results across various platforms. I also used dslreports as it is very simple and not flash-based.
Ookla also offers a new PingTest, and here’s the result, obtained today:
Some very small adjustments caused very large discrepancies in results, so please do not take this first batch of tests as gospel!
iPhone teethering required teethering to be enabled on the iPhone first. I only tested via the USB, though I will soon be testing via BlueTooth as well. I expect BT to yield slower results.
|iPhone E||iPhone 3G|
|SpeedTest d/l kbps, u/l kbps, ping ms||75, 0, 715||5430, 252, 223|
|dslreports||108 kbit/sec |
|1553 kbit/sec |
|CISCO GIST||432 kbps|
|Xtreme Labs||195 kbps |
|3270 kbps |
This is only my first attempt, so the methodology will eventually improve and hopefully the results will have a smaller delta, which right now seems to be very high due to poor “ritualization” .
The results seem to indicate a download speed around 4 Mbps using speedtest.net and around 1500 kbps using dslreports. The download speed on 3G was around 2.38 Mbps on the tethered computer and a whopping 5.43 Mbps on the iPhone. dslReports indicated a download speed around 900 kbps over 3G. The upload speed was consistent across all platforms / tests / browsers at around 300 kbps.
Subsequent testing will be published in the spreadsheet that can be found below, in Sources. To use teethering on Fido, you have to subscribe to a plan higher than 500 MB / month. I do subscribe to such a plan and find that my usage is far below 500 MB, so I will most likely downgrade soon. This could make it impossible to tether, though there are instructions on the ‘net suggesting that it is still possible
You have to go to the link below, in custom-profile, and then choose your provider. I have not tried either one, so I do not know if they work – use at your own risk. You then should ensure that the profile is installed by going from your home-screen to Settings > General. Scroll to the bottom and tap “Profile”. You should see the “rogers_com.mobile” profile. In case you were wondering, here’s what they contain.
