FreiFunk Summer Convention (video interviews)

polylux – aktuell

Berlin radio-station, Polylux has a short realvideo piece about the recently held FreiFunk Summer Convention, which we (wire.less.dk) participated in. The piece is in German and features some of europes most active community networking folks, such as my colleagues Sebastian Büttrich and Julian Priest, and our good friends Armin Medosch and Jürgen Neumann.

If you understand german and are into community wireless, or just want a brief intro to what all the fuss is about, listen in.

Wireless Lan – digitale Revolution oder schnöde Netz-Piraterie?

Hightech-Idealisten basteln europaweit an freien Funknetzen. In Berlin treffen sich die Cracks der
Community, um ihre Vision von kostenlosen Bürgernetzen voranzutreiben.

solar powered wireless security camera

Proxim, Hutton Ship Solar-Powered Wireless Camera

Interesting product shipping from US manufacturer Hutton Communications

A combination of wireless gear including a directional yagi antenna, a security camera, and a solar power solution.

Why is this interesting? Take away the camera, replace it with some sort of low-power computer, and it’s pretty close to what we are trying to achieve here at wire.less.dk, for use in remote regions of the developing world. Solar-powered, autonomous connectivity.

The Solacam (that’s right, no “r”) uses a mixture of technologies to deliver a remote digital video signal back to your network. Chief among them is use of the Proxim Tsunami MP.11, an 802.11b-based, point-to-multipoint backhaul solution with a range up to about 12 miles. The Solacam itself is an IP video camera mounted on a freestanding pole in a remote location, powered by a battery that is charged by a solar panel that’s also mounted on the pole. A Yagi directional antenna points the low-res video back to home base (assuming it uses the MP.11 subscriber station… the pole could also house the MP.11 base station). The MP.11 and battery are housed in an all-weather enclosure.

Hughes offers Satellite / WiFi combo

Reiter’s Wireless Data Web Log : Hughes offers WiFi package with direct satellite system

Alan Reiter notes that Hughes Network Systems, has announced a satellite/WiFi combo, targetted at owners of RV parks and similar.
It looks like it’s basically a WiFi access point bundled right in there with the satellite system, which would allow for a very easy way to provide (expensive) bandwidth to remote locations.

Hughes Network Systems today announced a supplement to its Directway two-way, fixed satellite system: WiFi. The new product includes an external WiFi access point, and the system is targeted at owners of parks and resorts catering to owners of recreational vehicles.

The press release doesn’t include much information, such as data rates and costs, so I called the women who sent out Hughes’ press release. Airtime costs for service will be determined by the owners of the RV parks, so I wasn’t given any figure for what it would cost to use the service.

More Voice over wireless news

CommsDesign – NEC, Motorola partner on Wi-Fi/cellular connectivity

According to this Press Release, NEC and Motorola are joining forces to bring out products in this space where WiFi wireless networks and Voice-over-IP converge.

Yet another confirmation that we’re not alone in supposing this is going to be a really interesting area.

Unfortunately the Press release is pretty much without content. It says nothing (really, it doesn’t) about timing, or whether there are specific goals for this cooperation. Oh Well.

NEC America Inc. (Irving, TX) and Motorola Inc. (Arlington Heights, IL) have announced their intent to collaborate on an enterprise communications solution that converges a wireless LAN voice over Internet protocol (VoIP) network with cellular phone systems.

Tactical Tech Summer Source on the Island of Vis, Croatia

Tactical Tech

I’ll hopefully be attending the Tactical Tech Summer Camp for NGO’s, on the Croatian Island of Vis in early September.

If all goes well, I’ll be showing of some Open Source wireless solutions, and hopefully demoing some VoIP systems, including Voice over WiFi .

In any case, the Summer Camp is cool, the Croatian coast amongst my absolute favourites in Europe, and the people there should be really, really interesting. All-in-all a hoot and a half.

Venue: Island of Vis, Croatia,
Date: August 29th to September 6th, 2003

The Tactical Technology Collective Amsterdam and Multimedia Institute Croatia, in partnership with the Open Society Institute, are hosting Summer Source Camp, a nine-day gathering of individuals and organizations working to implement Open Source solutions for civil-society organizations (NGO’s, activists, educators and independent media). The camp will offer parallel tracks for implementers and developers, with numerous shared sessions and a project fair.

More VoIP over WiFi

The Register: Agere designs wireless VoIP chipset

Media attention is growing in the area of Voice over WiFi. Enabling Wireless PDA’s or dedicated phone handsets to communicate via standard Voice-over-IP, would allow really low-cost, mobile telephony in the office, the warehouse or the home.

One of the more important recent announcements in this area is Agere’s announcement that it will launch an integrated chipset that combines VoIP and WiFi, in one low-cost chip.

Agere’s wireless VoIP phone technology offers the promise of making low-cost, mobile phone calls over the Internet more widely available once the chips become available from September.

Search Engine for low-bandwidth connections

Someone forwarded me this article from the BBC Online: BBC NEWS | Technology | World’s poor to get own search engine

Researchers at the Massachusetts Institute of Technology (MIT) are developing a search engine designed for people with a slow net connection.

Someone using the software would e-mail a query to a central server in Boston. The program would search the net, choose the most suitable webpages, compress them and e-mail the results a day later.

The project website is here:

My question is: Why would anyone want that?

Voice over WiFi, more mentions

Fortune.com – Fast Forward – Will Wi-Fi Revolutionize the Phone?

Yet another article about the up-and-coming combination of WiFi and Voice-over-IP systems. This one from Fortune.com

Again, a lot of people seem to agree that the cellular companies need to take the threat of really low-cost voice over various public networks, seriously. While, of course, cellular can live a long time on the convenience of near 100% coverage, and the ease of use and ubiquity, there is a lot of money to be saved in certain niche areas, from alternative communication networks. One of the most promising might be the use of PDA’s or dedicated devices to get really low-cost international telephony from the road.

The bandwidth requirements of Voice-over-IP are negligable compared to the average throughput on a commercvial WiFi network, and it is possible to have a decent conversation on as little as 20kbit/s.

In short, if you have serious telecom bills, a need for international voice communication while on the road, and the willingness to experiemtn a little to get a significant saving, voice over WiFi might be for you and your company.

If you don’t, it may well get to you anyway in the next 3-5 years. In the meantime, my company specializes in WiFi consulting, and that includes Vocie over WiFi, in theory and in practice.

Better Pricing for Commercial Wireless Service

Peterstar to Invest USD 500,000 in Wi-Fi Hot Spots around St. Petersburg | RosbaltNews.COM

It seems that PeterStar has a much more realistic view of WiFi pricing than most of the providers I’ve had the ‘limited’ pleasure of making contact with.

According to this article, they are planning commercial WiFi service in St. PEtersburg at a price of about 1 Euro pr. half hour. Compare that to metronet’s 20 Euro for 2 hours on pre-paid, or even worse with Telia HomeRun’s subscription based pricing, and it seems like a different world.

At that price it’s worth picking up half an hour with your Latte, just to sync that mail, and check out the movie-programme.
