contextual studies, wireless conections

WIRELESS CONNECTIONS, OPEN, FREE


Wireless connections are everywhere, travelling through the microwave´s frequency, they get anywhere where theres a wireless router, and from ther to PC´s laptops and PDA´s. This service is something most of the people pay for, but there are other ways of getting it with out paying, and this way is connecting a laptop with a Wi – Fi card to a wireless signal originated from a nearby router. These days, it´s starting to become something big, and there are nets formed with people that go Wardriving; these people are Warchalkers, and they go around the city with their cars and laptops equipped with Wi – Fi technology that try to detect where are any wireless signals, and put them in a map in internet and also put symbols around the city indicating which places are available for connection. They may also use GPS devices for the exact locations of the signals, and thay also may install antennas to send this unused amount of broadband. These movements are not legal but there aren´t illegal neither. Its legal to look for networks, but not to use them with out authorization. Apart from this, governments may think that Warchalking and Wardriving can help hackers and terrorists in their proposes.
This is a small piece of what future is going to be with any kind of networks. Why pay for something when you can get it for free and doing it the same way as millions of people, what makes it very difficult to get caught. Soon all networks will be one massive signal that will provide everything from tv sign to internet, and it´ll be for free, considering that sharing and trying to get things for free are two practices that are gaining adepters everyday and that all ready exist in a lighter version in citys like San Francisco.



notes from todays lesson
The claude, (nodes), wwireless acces in stations and very crawded places.

The signal of a wireless conection gets weaker with any thing that is in its way, like rain, leaves people, metal... Best places for putting routers are high buildings all though its hard to permission for installation

Peer agreedment (agreedment between two major peers like states or countries, that negotiate about broadband exchange between them.


UK--------US I.E. WHEN YOU TYPE .COM INSTEAD OF .CO.UK
/ \ / NTL BT
/ ME STARBUCKS
ME

SYNCHRONUS: when you can send and recivve the same amount
a " : when you recive and send in differen levels, you recive about 8 times more than what you can send. Thi is the difference between DSL and ADSL

Pico - peering: organized networks between a comunity of people like neighburs, and works with mesh ap tecchnology
