Shiny Shiny iPad

Well as I posted a while ago I was one of the winners of the CWSP competition. I am glad it was then and not now as I have been busy. However I did win the iPad and much to my disappointment and a few circumstances beyond my control I have not had the time to get right into it, however thats about to change.

I will be setting the iPad up properly tomorrow, my usage will be mainly for reading and studying, usually in bed as its much easier to lie back with the iPad than a laptop so I have to get a pdf reader on it and download some material. Shouldn't be too hard but everything has to go through iTunes which I was not a fan of, maybe thats changed, we shall see.

My first impressions though were great, out of the box it connected straight away to my secure wireless network, I haven't tried it with PEAP or other higher level security yet but I am sure I will.

Surfing the web is easy if a little clunky when you are used to tabbed browsing, maybe theres and app for that.

I liked the quality of the screen, very clear and bright even thoug a little small its a good size to pick up and read from. Zoom capability is great and really responsive.

All in all I am quite pleased and will be making use of it, target to get some material loaded onto it tomorrow and look at other apps in due course.

Standards Update 802.11n Download

By far the most important change to wireless ever the 802.11n standard is now available for free download.

As from my previous blog I gave details of all the wireless standards that are freely available this should certainly be added to your collection.

It can be downloaded here

http://standards.ieee.org/getieee802/download/802.11n-2009.pdf

For the other standards here is a link to my previous post which is updated with the 802.11n standard

Blogging

Well its been a while since I blogged as I have been busy, you know how it is, you always need to focus on other things.

Well I also need to focus on my blog or it will surely die and maybe I am going to change the way I do things a little.

Instead of summarising chapters I read I am going to try to highlight the things I learn.

I have read afew more chapters of the CWNA book and although I probably know quite a lot of the information its interesting to find out what you do not know. More about that tomorrow though.

There is also the work life balance, I lock myself upstairs in the office and nobody bothers me which is great but then I have to exercise my dogs, and get more exercise myself. Currently trying to shed a few pounds and cycle more in the good weather.

I have also reassessed a few things and timelines for certs etc and I have decorating to do so busy life, thats besides having to do all the work stuff and personal admin like banks etc.

There simply are not enough hours in the day so I will have to change they way I blog a little.

It will still be about wirless and wireless related but if we take the CWNA blogs as an example maybe not as much detail.

I am just finishing chapter 5 of the CWNA so will write more tomorrow on that but I also need to get reading the CWSP aswell if I want to take advantage af my package.

I also need to tell you about my shiny shiny new iPad that I won from CWNP and get that all up and running.

So lots to tell just keeping it a little simpler.
