3G Mobile Gateway Pack

This is basically a mobile Wi-Fi access point that uses a 3G cellular network such as Verizon's EV-DO for its backhaul.

Entrée Wireless, a leading developer of Mobile Wireless Gateways, and the California Institute for Telecommunications and Information Technology [Cal-(IT)2] will deploy Entrée’s technology solution to provide high-speed wireless connectivity in the field for first responders in disaster situations.

I couldn't get the sense of this--why not have the first responders connect with the 3G network directly? Then I read this:

The system is noted for its proprietary Bandwidth Limiting Technology (BLT) that protects the cellular network, and its provision for Incremental Revenue Generation (IRG).

I guess it assumes that Wi-Fi enabled laptops and PDAs (and soon to be smartphones), will become the standard for the first responders. It's certainly less expensive than the current $80/month fee for 3G.

UPDATE: I ran this past Glenn Fleishman and received this prompt response...

Fortunately, you can turn any Mac OS X 10.3 or Windows XP laptop into
the same thing. Windows and Mac OS X (10.2 has this, but 10.3 is
better) allow you to bridge connections, so you can share a 1xEvDO connection
over Wi-Fi as a software base station. It's not as free-standing as the
unit in the PR above, but get a couple of external batteries like the
Valence or the $100 freestanding battery unit I got from Costco (DC,
AC, charges off AC or car DC, etc.) and you could run an LCD-off laptop for
probably a full day without recharging.

Of course, this is something that you need to clear with 3G carrier first.

I would prefer to see a service where first-responders could receive a discount on their 3G for their involvement with a program that could provide educational as well as emergency alerts using a handset of their choosing. They would also have the ability to send video of a situation that others may review to determine if a terrorist attack has indeed occurred. This would better take advantage of the ubiquity of the 3G signal over Wi-Fi.

UPDATE 2: In response to my statement about notifying the carrier first Glenn writes:  No, no, you don't! You just get the cell data connection up and hit share. I mean, it might violate the AUP, but it's untrackable.

Cellphones with Wi-Fi

Engadget.com is pointing to this article on Wi-Fi Planet. They call it a "dual-mode" phone which I think can be confusing, and a better term is needed.

The article talks about the upcoming Motorola Mpx300, the HP 6300 series, Nokia's 9500 Communicator and a T-Mobile phone to be announced.

I told by a rep at Vonage that in 2 months a beta version of their software for the PPC platform will be available. Right now, you can pay $250 for a "mobile" phone (Pulver's WisIP or Zyxel's Prestige 2000W) which will give you access to a free service such as Free World Dialup. "Mobile" is in quotes because these phones are probably better used on a home or business network where it's not necessary to logon to the Wi-Fi network. Carrying such a phone with you just to use at a premium hotspot might not be the most practical solution.

I would hope that these Wi-Fi cellphones come with at least a 1800 mAh battery (removable is preferable). The Axim X3i I was using has only a 950 mAh battery and was providing about 3 hrs of continuous Wi-Fi service.

Doc Searls' IT Garage

What is this, and why am I linking to it?

The subhead describes its purpose: News, ideas and real world stories about how IT folks solve their own problems. Doc Searls is well known in the blogging community but also serves the print media as senior editor of the Linux Journal. He's one of the co-originators of the Cluetrain Manifesto and is famous for the quote: Markets are conversations. If I understand his intent correctly, he means to say that the end-users of technology should be the driving force in determining how systems are implemented.

Some new developments such as VoIP are being described as "disruptive" in that the major telcos now face unregulated competition by companies such as Vonage. In my view, disruption is only meant to be a temporary state, as new contracts are negotiated to integrate VoIP as a readily available long distance service. And there are telcos, e.g. Qwest and AT&T that have the foresight to create plans to use VoIP.

Perhaps a better term to describe the ultimate goal is "transformative." Here the technology is perceived as providing the desirable qualities such as efficiency and economy, and its implementation is meant to change the work habits of the end users. But again, there can be sweeping transformation directed by the CEO ("Our hospital is wireless!), in a top down fashion, that is too general and doesn't address the particular problems of different departments of a company or a hospital. It has already happened that clinicians have rejected new CPOE systems because they were just too much of a burden to try to make work.

Finally, you can consider the "normative" approach. Here end-users are adapting technology they are already familiar with, such as PDAs or smartphones to make the tasks easier to accomplish. Adapting technology in this way requires little training, and starts with a commitment already established by the users. This is the bottom up implementation of technology that I think represents the spirit of the Cluetrain meme. Choosing and maintaining a handheld device or any other device that is used on a routine basis is a personal choice. Developing ways to allow professionals to use their personal technologies  in solving work-related problems is an issue I hope to see addressed on Doc's new blog. The emphasis is shifted away from what is used to who's getting the work done.
