Wired or Wireless, ADSL or 3G? that’s the question?

Friday, February 10th, 2012

I’ve recently been running trails using 3G Wireless Internet with Celltime Provider Three and O2, you are probably thinking I’m as mad as a badger! (well once upon a time, I did study Electronic Communication Engineering, so I know a little about Radio Frequencies! - (thanks to Mum & Dad! for the funding!).

But check the results below, and this is with a -85 dBm signal (boffin speak for GOOD! or three bars good buddy! have you got your ears on!), using the internal antenna on a Option GlobalSurfer III (3G Router). I’ve recently noticed that Three have upgraded their transmitter to now support HSDPA (High-Speed Downlink Packet Access), well what does that load of gibberish mean, well other than the UMTS or 3G symbol changes to “H” on my phone or router. It means that rather than max speed of 3.6Mbps, the max speed could be 7.2MBps or 14.4MBps. Yes via Wireless!

At present I’m getting faster wireless speeds than wired!

I generally use this 3G router, because when normal wired ADSL fails, it automatically fails back or fails over to 3G Wireless Internet, and after the recents drop outs and faults, I noticed my 3G wireless broadband was faster!

I need to complete some more calculations, and purchase a directional Yagi antenna, so I can get a stronger signal = more signal = more power = faster throughput and downloads! (does that sound like Captain Kirk to Scotty the Engineer - Give me more power! Scotty! )

This aerial is not correct, the VSWR (sorry boffin alert) is too high, and not correctly matched at 3G frequencies! It reminds me of long ago with a DV27 on a biscuit tin!

I now understand, when I visited China, why they did not role out copper wires to peoples houses for telephones, they just jumped to wireless 2.5G communications (whilst the UK, was still using GSM! (2G)).

Well Good Buddy Signing Off!, 10-10.
