Speed tests of Jio 4G Internet connection through JioFi 3 router in my Puttaparthi flat

Last updated on 18th Sept. 2017

Summary of results from Jio 4G WiFi router (JioFi 3) Internet speed tests conducted today (17th Sept. 2017) in my flat in Puttaparthi, Andhra Pradesh, India are given below. Note that the Internet service provider is also Jio (JioFi 3 router has Jio SIM in it).

Typical speed of Internet connection on Dell Mini-Laptop using JioFi 3 router connected via WiFi or USB was above 3 Mbps touching 9 Mbps+ speeds at times, though there were a few outlier-type lower speed readings including some below 1 Mbps readings too.

JioFi placed on window sill of balcony seemed to give some high speed results of 6 to 9 Mbps but sometimes gave lower speeds. JioFi being placed on table inside the balcony was giving almost comparable high speed results in the range of 6 to 9 Mbps but the number of tests done is smaller than that done on window sill location.

JioFi placed in vertical position on computer table in bedroom next to laptop gave most results in the 3 Mbps to 6 Mbps range with some results giving as low as hundreds of Kbps speeds and some giving high 9 Mbps+ speeds.

[Updates on 18th Sept. 2017: Late night/early morning (1 AM to 2.30 AM) speeds were typically in the range of 15 to 20 Mbps, though a few outlier results were lower.

In the afternoon (1 PM to 2 PM) in a shop on Puttaparthi main road which, I was told, is quite close to the Jio tower in that area, I got 25 to 30 Mbps speeds with an outlier top speed of 37 Mbps! end-Updates.]

Overall, I can say that the Internet speed seen in my flat on Dell Mini Laptop when connected to JioFi 3 router with 4G Jio SIM, via WiFi or USB, is satisfactory for my needs.

Detailed Speed Tests Log
========================

The (4G mobile Internet) signal strength indicator (middle icon) of the JioFi 3 router has four values (taken from leaflet documentation that came with JioFi 3 router):
1) Solid green: Good signal coverage
2) Solid blue: Fair signal coverage
3) Solid red: Poor signal coverage
4) Blinking red: No sim card/sim card error/No service

My observation has been that JioFi 3 router placed flat on the computer table in my bedroom usually gives solid blue indicator – Fair signal coverage, but sometimes gives solid green indicator – Good signal coverage. If I keep it standing almost vertically (within a cardboard box for stability as JioFi 3’s vertical base is very thin), it sometimes gives a solid green indicator and sometimes a solid blue indicator.

I forgot to change the Windows Update setting of (Automatic) Check for Updates before I did most of these tests. So any traffic from (automatic) Check for Updates could have slowed down some of the speed tests given below. Towards the end of these tests I changed it to Never Update and the point at which I did it is mentioned in this log.

USB connection speed tests
=========================
Now I got the JioFi router back to computer table, disconnected the WiFi connection and connected JioFi router to Laptop using USB data (and charger) cable (micro-USB on JioFi side). Note that the laptop has USB 3.0 ports which were used for these tests (and NOT USB 2.0 which may cap the speed to below 500 Kbps).

*) 9.17 Mbps, 5.55 PM, Good signal, http://beta.speedtest.net/result/6631520204

———–

Changed Windows Update setting from (Automatic) Check for Updates to Never Update. So that will prevent any traffic from Windows Update slowing down the speed test.

Changed JioFi 3 position to horizontal on computer table. Rest is same as above.

Location: Dell mini Laptop on chair in balcony, JioFi on balcony window sill (resting against insect-net window pane) with JioFi front side facing bedroom, Laptop connected to JioFi 3 by USB (only)

*) 6.3 Mbps, 8.00 PM, Good signal, fast.com
*) 410 Kbps (yes, Kbps), 8.01 PM, Good signal, fast.com
*) 6.0 Mbps, 8.02 PM, Good signal, fast.com

==============================

A little after the above tests, as I was trying out some more casual speed tests but not recording them here (as that takes time), I saw the speeds drop to a few hundreds of Kbps. I thought that my many speed tests may have pushed my data consumption for the day on this SIM/account to 2GB after which the speed dropped (official speed after 2 GB limit is 128 Kbps).

But when I checked the Jio portal for this account, it showed 800 odd (or was it 900 odd?) MB data available for me. I thought the Jio portal may not have got updated with the latest data consumption.

Around 10 PM I checked the Jio portal again. It still showed 800 odd MB data available for me. I checked the speed on this SIM (in router) and was disappointed to see below 1 Mbps speed. In the interim I had changed to using my first Jio SIM on Huawei USB modem/dongle and that gave a healthy 2 to 4 Mbps on laptop on computer table in bedroom.

I wonder whether the speed cap is getting applied in my 2 GB/day case after 1 GB itself!

Did some (additional) proper speed tests on the new SIM and router.
Location: Dell mini Laptop on computer table in bedroom, JioFi almost vertically placed on computer table next to laptop, closed bedroom-balcony door, Laptop connected to JioFi 3 by WiFi.

*) 3.0 Mbps, 10.15 PM, Fair signal, fast.com
*) 4.5 Mbps, 10.16 PM, Fair signal, fast.com
*) 4.65 Mbps, 10.18 PM, Good signal, http://beta.speedtest.net/result/6632055777
*) 5.45 Mbps, 10.19 PM, Good signal, http://beta.speedtest.net/result/6632058531

The above tests show that my earlier fears about possibility of speed cap having been applied even though I had not crossed my 2 GB/day limit, WERE UNFOUNDED. The above speeds seem to be healthy for the location of the JioFi device. Perhaps there is some other explanation for the hundreds of Kbps speed results I got earlier.

Same arrangement as above tests, but with WiFi disconnected and USB cable connection made between JioFi router and Laptop.

*) 2.2 Mbps, 10.26 PM, Good signal, fast.com
*) 2.5 Mbps, 10.27 PM, Good signal, fast.com
*) 3.53 Mbps, 10.28 PM, Good signal, http://beta.speedtest.net/result/6632077323
*) 3.07 Mbps, 10.29 PM, Good signal, http://beta.speedtest.net/result/6632079825

=======================================
To know more precise values of signal quality than Poor, Fair or Good, the JioFi web admin interface under its Status tab/page has three fields RSRP (Received Signal Received Power), RSRQ (Received Signal Received Quality) and SINR (Signal to Interference-plus-Noise Ratio). [For more on these terms see: Making Sense of Signal Strength/Signal Quality Readings for Cellular Modems, http://blog.industrialnetworking.com/2014/04/making-sense-of-signal-strengthsignal.html.]

The web admin interface page of JioFi 3 can be accessed by the URL: http://jiofi.local.html/ in browser of computer connected to JioFi 3 (by WiFi or by USB).

The article, Understanding LTE Signal Strength Values, http://knowledge.digi.com/articles/Knowledge_Base_Article/Understanding-LTE-Signal-Strength-Values, has a table with the value ranges of the three fields taken together, which are considered as Excellent, Good, Mid Cell and Cell Edge (signal strength).

Excellent has RSPR >= -80, RSRQ >= -10, SNR >=20
Good has RSPR from -80 to -90, RSRQ from -10 to -15, SNR from 13 to 20

At 10:41 PM the web admin Status page shows RSRP of -80 dBm, RSRQ of -11 dB and SNR of 21 dB. At the same time, the solid green signal strength indicator is shown on the front panel of the JioFi 3 router, which means Good signal strength in JioFi 3 documentation terms (and not above digi.com article terms). The Good signal strength term in JioFi 3 documentation may be mapping onto both Excellent and Good signal strength terms in the digi.com article.

At 2.19 AM, Jio portal for 2nd SIM (JioFi SIM) shows data availability as 756.00 MB from 2.00 GB! Also got an email notification from Jio at 2.11 AM about 50% usage on this number/SIM. So from around 12:00 AM (0:00 hours) to 2.19 AM, a little over 2 hours period, the above tests and some casual tests not recorded in above log, were the main consumers of 2 GB – 756 MB i.e. 2048 MB – 756 MB = 1292 MB of data!

Additional speed tests in Puttaparthi Main Road shop

Location: Tirupathi Rao Mobile shop on Gopuram Road (Main road), Puttaparthi. Dell mini Laptop connected via WiFi to JioFi kept horizontally on table inside shop. 18th Sept. 2017

*) 28.44 Mbps, 1.29 PM, Good signal I presume, http://beta.speedtest.net/result/6633452749
*) 37 Mbps, slightly before 1.44 PM, Good signal I presume, fast.com
*) 30.13 Mbps, 1.44 PM, Good signal I presume, http://beta.speedtest.net/result/6633484115

I was told that the surprisingly high speeds in the afternoon (on a weekday – Monday) in that location may be explained by Jio tower being close by. I was told that in that area the tower is about 100 feet from the main road (Gopuram road) on the side street leading to Shanti library.
