Since Vodafone upgraded the local mast here in Kilcar to provide 4G on bands 20 and 28, I have been testing this Vodafone prepay plan as my main Internet connection for my desktop PC and VoIP based landline over the past few weeks. With my current Poynting LPDA-92 antennas and the MikroTik Chateau 5G, it is performing very well between streaming, occasionally downloading large (5GB+) files, working from home, no sound quality issues on calls, etc.
The speeds I get are typically in the 60s to 80s during peak time and the lowest I've seen is in the 30s. I have seen suspect throttling a few times during peak time (around 8 to 10pm) where a download starts off very quick for a few seconds, then drops down to a fairly steady rate of around 40 to 50Mbps (5-6MB/s) for the remainder of the download. However, even when this happens, the speed is still much faster than what I often get on my Three broadband connection where the speed can down to single digit Mbps in speed tests.
One minor issue I encountered recently is with Vodafone appearing to run the data connection over a transparent proxy. When running speed tests with the
Measurement Labs speed test, I noticed it kept reporting a latency of 1ms regardless of what web browser I tested on, including my phone, where as the latency measurement is fine on Three (notice the speed difference ~11:15pm, Vodafone vs Three):
I e-mailed M-Lab thinking this was a bug and they came back explaining how their test measures the latency. They use a TCP based RTT to measure where the connection terminates from their server and reckons that there is some sort of proxy in the path. As the TCP connection is terminating somewhere within the Vodafone network, the latency ends up being very low like with any other connection from a data centre. This is different to a regular ping test that sends ICMP packets end to end, which is a different network protocol to TCP.
While I can ping hosts to get latency measurements, I have also discovered that Trace Route does not work, giving "Request timed out" for every hop after the third hop with any host. In this example I did a Trace Route to TestMy Australia which should give plenty of hop host names or IP addresses:
The TCP Trace Route tool which uses a TCP based TTL confirms the proxy as there should be many more hops than 4:
If anyone here has an actual Vodafone 4G or 5G broadband contract that uses the hs.vodafone.ie APN, try running a speed test on Measurement Labs to see if it also reports a 1ms latency or run a trace route to a host like Google.
Depending on the weather, this weekend I plan replacing the Iskra P-58's I currently use for Three with a pair of Iskra P-40's. These are low band (700-900MHz) antennas with a higher gain. I will try to do some tests between the two antenna pairs and possibly also test the Poynting XPOL-2-5G to see how well each performs on the low bands 20 and 28, which I will post in a separate thread. Once I replace the antennas and swap routers, I will cancel my Three broadband. According to Three, it must be cancelled by phone (not possible within My3) with 30 days notice.
