Yeah! Long time no writing but still hacking out there. I am really busy this days. Six weeks giving training for a big customer, consuming all the time I have, almost all the time. The time remaining, I need to dedicate to my lovely family. Well,give training is an amazing opportunity to learn, hold what you know in your head and learn more. It is an very good way to keep stuff alive.
The newer interesting subject is Hotspot. This is actually new. Was ratified early 2011 and it still being deployed for large companies. The fact is, hotspot takes wifi to a very interesting level. Its integration with Cellular network makes thing really nice.
I am in range to understand a lot of new concepts and the idea is write it down here for study purpose.
Basically Hotspot adds new functionalities to the traditional wifi technology by adding some activities after wifi pre activities. I mean, in a traditional wifi environment, you see the SSID being spread out there, you try to connect to that SSID using some kind of security or not and end up with a connection.
So far so good, after all, being connected will be always the objective or not ? But, it turns out that the process just described was never practical. You need to make the move. You always need to connect in some SSID.
What about Cellular Network ? Do you need to ask for you cell phone gets connected ? you don´t. Once you are in range with any network, you will be able to connect and use the service seamlessly. How is that possible ? and it is possible to have such set up on the Wifi world ?
The answer for those question will come later in new post.
Cheers! Wireless have been demystified in my head more and more. It is expected that in a few time I ´ll not see too much challenge by deploying wireless network. But, thanks to the market, new stuff are popping up and this keeps me busy.
