Idea #9755: Extend possibilities of wifi networks

Written by Mito the 11 Jun 08 at 08:17. Category: Internet & Networking. Related project: Nothing/Others. Status: New
Rationale
Social networks are very popular nowadays, but computers are very individual, we don't use possibilities of wifi cards in our notebooks.

I want go to my friend with notebook, she easily share her internet connection through wifi from her adsl/lan internet.

I want easy communicate, share files, talk with her through our wifi connection.

I want come to school, make small ad-hoc wifi network with my colleagues, play games, share with them my data, communicate, make temporary small chat room... Someone add internet to our wlan, through mobile.

In old times, we make small/big lan parties, why there isn't wlan parties ? I know internet is faster, but we can share without internet.

It means:
* easy connect ad-hoc with other devices (notebooks with whatever OS, smart phone (Windows mobile, symbian, iphone)
* easy choose ipadress, easy create dhcp-server
* easy create bridge to share internet connection
* easy create rules of connection (firewall)

In future
* easy make ad-hoc wlan
* easy communication through wlan, maybe ad-hoc jabber networks

ad-hoc wlan party, cool idea!

You can already create an ad-hoc wlan with Network-Manager. And if you have that, and configured samba and the other sharing services correctly, all of your ideas are already possible.

It would be cool if Ubuntu could support mesh networks, as from the OLPC project.

Neat!

Ad-hoc networks are indeed currently possible. These ideas seem very cool, and I'm thinking they would be best accomplished with link-local XMPP (Jabber) and Telepathy Tubes to send the information.

This would mean that when enabled, two laptops within range of each other will form a network automatically. Then telepathy will broadcast their user across the network (so I will appear as "chris@chris-laptop" for example). When an application, say a game, is started it would create a multi-user chat room on the link-local network to which each person can join, then tubes are set up to that room through which the games can communicate with arbitrary (ie. not just XML) data passing.

The possibilities of Telepathy really are huge, it's a shame the integration specs keep slipping releases (for example the official main Telepathy spec is called "feisty-telepathy")

Yes, great idea. I like the idea of easily creating an ad-hoc wireless network. I tried to do that but it took me forever and I never did get it working completely.

Bump on the mesh network idea. The code already exists. It's freely available.

It might even encourage interest in the awesome Marvell chip that the olpc uses. It can go 3km line of site, and it can still contribute to the mesh when the computer is off. I personally saw it connect across 2 huge conference halls in Berlin with tonnes of obstructions (people/booths/relatively tiny exit doors) and it still had great signal strength.

My wlan can barely reach across my apartment.
What are we waiting for?

It's darn easy to share a 3G-connection in an ad-hoc network in Windows XP, no so with Ubuntu.

Wi-Fi party could be cool.
Then you could create ad-hoc networks anywhere, without having cables, routers, or big chunky computers.
Just take your laptop, meet somewhere and its an ad-hoc network.

Upcoming Linux kernel 2.6.26 has support for Wireless mesh networking (802.11s).

+1, awesome idea! This is something I was planning to post on, actually. It makes sense, since there are some computers that already do that (the $100 laptop that was being designed for third world countries, for example) It's something that would be very useful.
