Whilst I was doing some scanning I found an article on Unwired hardware. Running on 3.4 GHz it is causing some interference with people using some free to air satellites. Regardless of this, the article included some comments on the technology of Unwired. For some reason Unwired don’t seem to say much about the technology that they use.

The actually use IEEE 802.16e, which is an emerging wireless standard operating on licensed frequencies between 2 and 6 GHz. Doing a quick search I found some more details on the standard. Frankly I am amazed. I did not think that the equipment being used by Unwired was going to be so advanced. Boy, I was wrong. The standard was deisigned to operate in vehicles moving at over 120 KM/h.

Believe it or not, this is a hard task to master. Rayleigh fading causes many problems with fluttering signals, particularly with higher frequencies and bitrates. The standard also targets spectral efficiencies that means that the standard will scale as the number of users increses. It is also optimised for low latency applications.

Scanning

Why am I scanning stuff? Well there are a few reasons. The stuff I am scanning is much of my technical library, but it is stuff that I almost never refer to but like to have there if I need to. I need to access some of it occasionally depending on what it is.

Another reason is for space reasons. Paper takes up a lot of room as you can see from the photos. Scanned documents take up almost no space. And they are seachable if you OCR them.

Some of the papers are old and starting to degrade so they would not last long. So scanning them and getting rid of the physical document would preserve the document.

Music:

I am listening to Matchbox 20’s ‘yourself or someone like you’ and I really love it. It WILL get placed into my car to play whilst driving.
