Proof of Concept: Portable WiFi

wifi backpack

graphic by Josh McKibillo

Ubiqutious Internet is something I hope to see within 10 years, but until then this is a proof of concept. In short this backpack gets Internet through a cell phone, beams it out over WiFi, and powers itself using the Sun. The process is detailed in this Popular Science article, which I hear about via Lifehacker. Right now it’s big, hacky, and expensive, but things should get smaller and cheaper. The Internet comes from a 3G network in the states called EV-DO, which Sri Lanka doesn’t have yet. Dialog is doing something, but I dunno how fast it is. You plug the cell card into a Junxion WiFi router and then you have an instant hotspot. The solar power is a bit of a vanity plate, but useful if you want WiFi absolutely anywhere.

EV-DO is about $80/month and really fast, I hope Sri Lanka gets something similar soon.

using BroadbandAccess (EV-DO), you feel as if you’re hooked up to a cable modem, even when you’re sitting on a beach, your deck or a speeding commuter train. When your signal is strong, you get Web pages in a flash, file attachments in no time and video feeds without a hiccup. (New York Times

If you plug an EV-DO card into your laptop or PDA you can get fast Internet all over the States as is. The WiFi backpack here means that you could use one card and provide access to a whole office or classroom. Seeing as the cell-phone network pushes out much faster than land-lines, this is a way to reach rural and poor areas with Internet. People in China and Africa are among the fastest adopters, so it’s a much faster vector for Internet than PCs and landlines. As cheap EV-DO networks get more popular, you could start getting Internet as easily as cellular signal.

A more developed ‘backpack’ might be a solar-powered phone that also transmits WiFi. Of course, it’s unclear that companies want you giving out free Internet – but getting one cell-phone and some cheap Indian laptops would be a faster way to network a classroom in Batticaloa than waiting for a cable rollout.

Looks del.icio.us :)

However, at the moment I’d be more than happy to have a proper internet connection at home. It takes ages to download the lightest of pages on stupid dial-up.

I’ll second that. Then again I don’t even have dialup at home. Meh.

right now I’m in Kandy on some horrible dial-up. I think coolies are actually carrying the packets downhill. As an alternative to watching images load pixel-by-pixel I’m trying this service by a bright guy who’s name I forget – and who it would take another half hour to Google.

It lets me view this and any page stripped of any formatting and graphic elements, and loads way faster. It’s meant for mobile devices, but it works pretty good for this dialup

It’s Benjamin Adam (Announcement). Cool tool.

I think the really cool part of this evolving technology is that when you are walking with your backpack into a public WiFi hotspot the EV-DO connection can be seamlessly handed over to the (free) public wifi. In most cities in the US and some countries in Europe, I reckon it would be possible to walk through one neighborhood to the other only using public wifi and relying on telco’s paid broadband connection intermittently. I don’t see any insurmountable reasons why public, neighorhood wifi networks as have evolved in Indonesia cannot be replicated in Colombo at least and may be other cities that have ADSL or other broadband connections. In Indonesia, broadband connections of offices, business establishments etc are connected to a WiFi box effectively creating wireless community broadband networks. If you visit my neighboorhood on 2nd Lane Nawala Road you should be able to enjoy free high speed wifi connection thanks to my wifi access box connected to my ADSL connection. Colombo 7 area is bathed in wifi signals. It would be great if some geeks could get together and map the wifi hotspots in Colombo for starters. That info would have some public utility.

This reply may be a little late, but please check out our service PHONifier, at http://www.phonifier.com. It’s open source, so you can take the source code and install it on you own server to act as your own proxy for mobile or low-bandwith access to the web.

We’ve just this week launched, at would be really happy to hear your comments or feedback!

Sarath Fonseka And The Mahavamsa

The Mahavamsa (a history of Sri Lanka) is full of conflicts between generals and kings. Usually, the more bloodthirsty and unscrupulous would win. Our current (elected) ruler Mahinda Rajapaksa has had his own general conflicts, namely with one Sarath Fonseka. In the old days Fonseka would have staged a coup, as in literally try to cut of Mahinda’s head, and Mahinda would – if that failed – tie him to four elephants and split his parts asunder. Can’t do that shit anymore. Instead Fonseka ran for office and lost and Mahinda tossed him in jail.

Why Does India Suck At The Olympics?

Today on the morning show we talked about the Olympics, namely China’s emerging dominance. For me the bigger question is India. Why does India suck so much? In 2008 the US won 110 medals, China won 100 and India won… 3. India has over a billion people, some economic clout and is by all counts an emerging superpower, but they suck at the Olympics. Why?

New New Kottu

Janith has updated Kottu with rims and shit. Seriously, it looks pretty good. You could say the desktop look is cosmetic, but check out the mobile. Kottu now looks like an app with settings and menus and such. The biggest problem with K2 is me, ie, it now takes me up to a month to respond to emails. OMG I’m scared of my email. But Janith’s done this code and design update all by himself and it looks pretty good. Check it out. There was one bug with the previous page link. Lettuce know if there’s any more.

Miss Travel. Alternately, Mistravel

This is highly dubious. Miss Travel is a travel/social networking site that connects ‘Generous’ and ‘Attractive’ travelers. To, like, travel together, I guess. It all seems a bit like arranged prostitution and trafficking. This is part of a broader online trend to connect rich men to younger, attractive women. Sites like seekingarrangement.com connects women to ‘sugar daddies’ already. I guess Miss Travel is just taking that trend international. Wait, I checked, it’s the same guy doing both.
