Connection Share

Correct me if im wrong but can't we now sell connections over Wlan?
If so why don't a group of people in the same area group togeather and get a kick ass connnection.

Most connections are 50:1 or 20:1 contention right?

So 10Mbit leased line probably arround 2k to 3k per month.

Each person pays £50/month thats 40 to 60 people paying that.

Thus 10Mbit for all :D

Is this a good idea?

I know Wlan max speed is arround 4 to 5Mbit!!!

Thanks

My wireless hub gives only 250m range and the aerial considerations are too mind-numbing to contemplate. Also details of the legalities are scarce from the Radio Authority.
Of course such a scheme creates a wirelsss hotspot with 3G capabilities so will be taking all kinds of traffic to all kinds of users and devices before long. Video chat would be no problem over such bandwidth.
None of this is probably very useful but demonstrates some of the efforts I have made in this direction. Good luck.
 
umm... your 10mb leased line will cost you a lot more than that a month! ..

Always Internet will sell you a 2Mb line for £1400 per month. I cant seem to find a 10Mb leased line price.

Ironically enough, £1400 at a 50:1 contention will get you a £28 per month (non profit) 2Mb connection.

Doubt you will get 2Mb to everyone though...
 
I did have a look at the TDAS site and clicked for a look at their local networks section (as seems relevant to this discussion) and it is 'coming soon'. Why oh why can people not put any old crap on their sites instead of a message advertising their unreadiness - seems dumb business to me. Or do not include an unprepared section yet. This is a common 'net fault and always cheers me up.
I do try to be constructive with posts but not always the way things are.

We are sharing a leased line using W-LAN already. ( <a href="http://www.crw.uk.net" target="_blank">http://www.crw.uk.net</a> ) The numbers mentioned work out roughly. The leased line is about £3k for setup and £1200 a month for 2M, and it seems you need to build a network of about 10 access points to cover all the people that want the service. These are about £500 each plus installation etc, so there's a bit of extra cost. Also you need to take into account tech support and stuff.

Wonder if you could clear something up for me.
I and other in my area are considernig some form of community broadband service.
A leased line say of 2mb (is that a true 2mb, as in approx 1 and a half floppy disks worth of data a second? Or is it just like 4x adsl so, say about 240 kilo bytes. As I am puzzled how say 40 users could get a 512 kilo bits dedicated connection from it. please could someone clear it up for me.
 
A 2mb leased line is in fact 2 mega BITS per second. You are thinking in bytes (8 bits to a byte). It is one of the confusing points about bandwidth. As a rule of thumb, any comms circuit, be it modem, ISDN ADSL or leased line tend to be offered in Bits rather than bytes. Even though there are 8 bits to a byte there is another consideration, IP packet overhead (ie all information has to have destination/source IP information embedded).

Some tecchies out there may correct me on the exact figure, but as a rule of thumb, divide the leased line speed by 10 and this will give you an approximate figure of bytes per second throughput on your 2mb leased line.

With regards to your other issue I can only assume that the figures quoted are for contended bandwidth and not dedicated.

I was also under the impression (may be wrong)that Wifi technolgy, utilising the 2.4Ghz frequency spectrum could't be used as a commercial model for distributing bandwidth, with the intention to sell on to users

Easynet and BT are however offer a "lan extension service" where you can link 2 points up at 10mb via an ethernet connection. BT is limited to the 2 points being within 25Km though

Their full press release is here -

<a href="http://213.38.88.251/coi/coipress.nsf/567e3dc25f61661580256ae8003b4907/6b1fdd771a705da480256bd40037fdf7?OpenDocument" target="_blank">http://213.38.88.251/coi/coipress.nsf/567e3dc25f61661580256ae8003b4907/6b1fdd771a705da480256bd40037fdf7?OpenDocument</a>

The only downside to the UK 2.4Ghz legislation though is that it limits you to a 100 Milliwatts power output level which will only allow you to extend your WLAN over 2 or 3 miles at very best. The speed of your connection also degrades the further apart you place your wireless equipment.

On a more positive note, the latest press releases from the Radiocommunications Agency (the DTI agency that deals with WLAN law) say legislation is planned to be introduced by July 2003 to allow WLANs to be extended using the 5Ghz band at a far more generous power output level of 2 Watts. This should allow WLANs to operate over far greater distances and at faster connection speeds than is legally possible using the 2.4Ghz band.

The Radiocommunications Agency home page can be found here -

Hope this is of some help.
