Open Mesh Networks

Hi all. Has anyone any experience of these?

Looking like the best option for providing wifi for the punters.

www.openmesh-uk.com

The units are here: http://www.openmesh-uk.com/index.php...acturers_id=10

With basic set up instructions here:

http://www.linuxplanet.com/linuxplan...orials/6758/1/

It all seems remarkably easy. As I say, has anyone any experience with these and can provide any advice on potential gotchas?

No experience ... how about HomePlug devices, but the one's that emit wifi too? You could run wireless extenders across the site?

I take that back, the open mesh stuff looks the biz. Especially the outdoor stuff too.

Wanna hand?

I did a short report on wireless mesh networks for my OU degree... but it was focused on HomeMesh and the ETX metric it uses.

I found that...

Quote:
When compared to other wireless mesh network technologies, such as Hyacinth. HomeMesh uses a less complicated channel assignment algorithm, meaning a lower routing overhead. Additionally, unlike Hyacinth, HomeMesh does not use a centralised system management so there are no problems with scalability.

[...]

One function to highlight using HomeMesh is that the mesh routers themselves are self-configurable and self-organising. They are constantly monitoring the traffic across the network and maintaining a list of available paths to the Internet. For example, if the original path is congested, it will divert the traffic on to a better path.

[...]

Expected transmission count metric is also known as the ETX metric. Normally routing protocols use a simple minimum hop count to select the routing path. However, this method does not take in account the effects of link loss and interference of adjacent links. HomeMesh, improves this throughput of the access path to the internet by using the ETX metric to select a path based on the sum of ETX.

http://www.wicoms.com/ supply the infrastructure and software for the Camping and Caravanning Club wifi networks, there some info on their site, may be worth tapping them up for a quote, you should at least see what they would put in for you.

Cheer Burundi - I kind of want to do it myself - so that when it 1)fucks up I don't have to phone someone and 2)the challenge

Dave - fuck off.

Blurr - these things are 'self-healing', however the gateway router will not be in the middle of the the mesh which is a bit of pain, as the bandwidth avail halves every router hop. Not ideal.

Bilb - why don't you come over and we'll chat about it. I'm about this weekend. Bet you're not.

With regards charging for it - if I get a dedicated line, then it will cost around 360/year for the line, which I can't swallow if I don't charge. Initially, I'm thinking of splitting my line just to see how popular it is before installing a new line - if I split it, it will be free.

Hmmm if the bandwidth halves every hop, then it's going to drop off quite a bit by the time it gets to the far end. It might be worth trying homeplugs (with Wifi extenders) in protected outdoor sockets.

I thought you might have been on Baschurch Exchange, as that has got BT Infinity, but unfortunately not.

hahahah normally I'd be kid-free this weekend, but I'm off on a rowing team event on Saturday!

I agree, you should test it first to gauge popularity, and then perhaps next season start to charge for it ... put in a dmz to capture traffic, and then a paywall. Fairly simple really.

This is from the Wicom site:

Quote:

What you need to know when providing internet access
to your guests and visitors

There are four main areas where legal and regulatory requirements can impose obligations on establishments providing Internet access to their guests and visitors:

1. Data retention
Relevant law and regulation includes: The European Directive (2006/24/EC) which has been implemented in the UK under the Data Retention
(EC Directive) Regulations 2009 and the January 2004 the Code of Practice (for voluntary retention of communications data) implemented
under the Anti-Terrorism, Crime and Security Act 2001.
Under the above, certain types of data are required to be retained necessary to identify end users accessing the Internet. The type of data to
be retained is traffic data and location data which can trace the source of a communication. Examples of relevant data include:
User ID; name and address; date and time of login and log off; IP address allocated to a user; the digital subscriber line (DSL) or other end
point of the originator of the communication; the internet service used (“communications data”). The communications data required to be
retained is data which typically shows the “who”, “when” “where” and “how” of a communication. The Home Office would expect such data
to be retained for a period of 12 months. As a matter of best practice an establishment should have in place facilities to store and access
communications data for a period of 12 months from the date of the data coming into existence. The purpose of maintaining communications
data is to assist intelligence and law enforcement agencies such as the police in their investigation of criminal and terrorist activities.
In practice intelligence and law enforcement agencies will request communications data from whoever is best place to provide the data. This
would include holiday parks and similar establishements in cases where hotels offer Internet access is offered to their guests and residents.

2. Law enforcement requests for information
Under the Regulation of Investigatory Powers Act 2000, intelligence and law enforcement agencies such as the police can direct that
communications data be provided for the purposes of investigation of crime. It is therefore very important that any communications data that
the police or other law enforcement agency may require is stored and capable of being accessed upon receipt of a valid request for the data.

3. Data protection
Under the Data Protection Act 1998 any user of Internet access services in a holiday park or similar establishment is entitled to request at any
time details of his/her personal information held by the establishment. Failure to securely maintain and make available data to a data subject
(e.g. guest, visitor or holiday home owner) is an offence and may lead to the imposition of fines by the Information Commissioner.

4. Copyright Infringement
The government is currently pressing ahead with its Digital Economy Bill which is designed to implement steps to reduce online copyright
infringement by end users. The Bill will cover illegal downloading of copyrighted material and illegal file sharing. The Bill when it comes into law
(expected to be later in 2010) will prescribe obligations to keep end user records to assist copyright owners in identifying, and taking action
against copyright infringers.

Conclusion
Law enforcement and intelligence agencies are extending their reach to tackle on-line criminal and terrorist activities. Increasingly, terrorists,
organised criminals and paedophiles are exploring news ways to communicate as anonymously as possible to avoid detection. Law enforcement
and intelligence agencies and the Home Office have identified that transient use of Internet access within hotels is increasingly becoming a
communications tool for terrorists and criminals. We can therefore expect to see an increasing interest amongst law enforcement and intelligence
agencies with regard to Internet access offered by establishments where guests gather or stay. The same applies to copyright infringement
activities where there has been an increase in illegal downloading and file sharing activities in establishments where users (wrongly) believe they
can access the Internet anonymously and escape detection.

So without logging who's using the service you're assuming responsibility yourself ? What/where/who are the punters in this case Norf ?

Yeh, the responsibility is the point that has given me pause for thought. You need to be able to prove that someone has been doing shit and it ain't you. However, the open-mesh dashboard can provide vouchers. The system basically gives you a splash screen where you say no downloading yada yada, and forces you to enter a code before you get access to the internet. This code is valid for whatever time you set it valid for, and in order to fulfill the data retention part of the policy, would be recorded against that person's name and address. We take everyone's name and address as a matter of course when we book them in, so would simply be a case of adding another column to the book.

If anything dodgy happened on my IP address (that wasn't me haha - which was my main concern) then the time and date of the use would correspond to the voucher's use date. I think that's the plan anyway!
