Re: Just joined and half data gone without actual usage (Happened on 2 different accounts)

@AE_Collector 

 

Speedtests work by trying to ram as much data up and down as possible, as fast as possible.

 

They deliberately push and pull more packet requests across the network than any device or network could possibly handle - it's a synthetic benchmark but the end result is real numbers for how much data was sent and received.

 

Data sent and data received all count towards billable data provision, of course.

Sounds reasonable but that doesn’t answer whether there is a set amount of data moved to see how long it took which would not result in higher data consumption if 4G rather than 3G OR if a set amount of time is used to move as much data as possible within that time frame which certainly would consume more data on 4G versus 3G than in the first method.

How I understand it is that that initial ping test they do determines how much data will be shovelled across. Oh hey look at that, super-fast ping time...ok let's give'r. Or hmm well we see a fair to midland time so we'll keep the volume down.

The larger the volume the more accurate the results...as I understand it.

The data itself is a bunch of random garbage files with standardized block sizes, fetched from the speedtest servers then sent back, arranged contiguously because read/write and transmit/receive operations are always fastest for sequential data access.

 

The speedtest app doesn't care how much data it uses - it will hog all available memory and all available bandwidth, it just deletes the temporary mess when it's done. The "set amount of data moved" is "as much data as the device and the network can move during the test".

 

If you are connected to a fast network and your device has fast processing then it can consume a lot of data in a single run. It's trying to move impossibly huge data before cutoff, but the bottleneck from the network or the device will impose a real limit and thus a real performance result.

 

When I run a speedtest from a home computer with 10Gbps optik it downloads almost 70GB  and uploads almost 24GB because the network bandwidth can support it and the computer can process it. And this represents less than 10% of the actual packet requests sent by speedtest, it would consume 1024GB if the hardware could sustain a fast enough rate before cutoff.

 

Mobile devices are not as well-equipped for large data loads. Wireless networks are pitifully slow and low bandwidth rates compared to wired networks. But speedtest can still gobble up most of a GB per run on a decently powerful mobile device with uncapped LTE data access, good signal, and low network traffic conditions.

Okay so while there may be lots of variables in the test, for the most part it sounds like a “timed test” where far more data is likely to be sent if on 4G rather than a 3G which adds up for what is being said/claimed here... lots of your monthly data allotment gone quickly doing a speed test while on 4G!

But everybody'll do it once and go holy crap! My data's gone! And then come complaining that PM stole all their data. Sigh.

Thankfully I wasn't curious enough or was clueless enough that i never did that when i joined pm. I learned quickly enough not to do any speed tests on my $10 account. But to prove a point about data speed differences and either saving a member from needlessly wasting their data on a speed test or showing someone that the difference in quality between 3G and 4G speed is indiscernable I play the same YouTube song/video and record the amount of data used. The 4G will always use a minimum 3+ times the amount of data than the 3G video does and saves the member from burning up a couple hundred MB of data.

I don't bother with speedtests for mobile data.

 

I expect the "3G" at 3Mbps to be very consistent because it's an artificial cap on 4G (and soon 5G) machinery which is designed to sustain more than 25x faster bandwidth specs.

 

While WiFi speeds are faster still:

802.11b = 5.5Mbps to 11Mbps

802.11a = 20Mbps to 54Mbps

802.11g = 20Mbps to 54Mbps

802.11n = 100Mbps to 600Mbps

802.11ac = 200Mbps to 1300Mbps

802.11ax = 2000Mbps to 10000Mbps

 

Most modern smartphones (and wifi routers) support 802.11 a/b/g/n/ac, they default on n/ac but will use a/b/g (or at least a/g) when connecting to antique wifi equipment. But if a smartphone can only get lower values (like, say, 18Mbps or 85Mbps best speed) on multiple Wifi networks then it's apparent the phone's hardware is the maximum-speed bottleneck, not the network hardware. And it's apparent the same hardware-imposed maximal limit will apply to every kind of network the phone connects to. Some phones (expensive phones) are able to approach maximal specs for bandwidth standards, most phones can only handle lower end performances.

Oh okay, I hadn’t noticed the typo (?) of 5Gb speed as opposed to 3Gb and assumed you were saying, No, it is 3Gb right from the get go.

 


That's not the case. When a new customer activates on one of the current "3g" plans, the data is much faster for the first 2 days. The 3Mbps speed limit doesn't kick in until a couple of days later.
