Wi-Fi Communicators For the Real World 119
Erik_ writes: "In this most interesting article on MSN Wearable Wi-Fi - The wave of the future?, there is a description of a Wi-Fi Communicator device. Just like on Star Trek (Thanks Gene), these devices provides hands-free, voice-activated communications throughout any 802.11b networked building or campus. The company manufacturing these devices Vocera hopes to begin selling the equipment later this year. Can't wait to get my hands on some of these communicators... Beam me up Scotty."

There's no new technology here - my NexTel phone already does every part of this except WiFi. The only thing new is the miniaturization. I think this would be a pretty cool app for an internet company - I work at a company with geeks on two continents, and I'd really like to be able to do this kind of communication with people at work. They have WiFi there, and I have WiFi here, so there's no reason why it couldn't work. You could use SMTP+MIME as the transport layer if necessary.

Sure, but what do you pay a minute (during business hours) for being able to use those full-featured cellphones? I think the groundbreaking part with Wi-Fi is that once you pay for the system, your hourly costs are zilch.

Your statement is true if you oversimplify it down to "people talk to people wirelessly."
Here's what this can do that a cell phone cant:
- No need for phone #'s.
- No airtime charge
- Since it's all TCP/IP, you can link two buildings together via the internet, as opposed to having to use a landline or something.
- To make a laptop or computer talk on the same network, it's all done via software. No extra hardware needed.
- Technology like 'video phones' becomes possible and reasonable to try. (again, thanks to 802.11)
... and so on.
I work in a small company, but I'm sure we'd love to replace our phone system with these devices. Picking up the phone when it rings can be distracting. It's easier to hold on to your concentration if all you an do is say "go away."

Another cool thing is that end-to-end packet-based systems are incredibly flexible and have no per-minute charge. You could imagine a "dual-mode" phone (I guess we're up to four modes or something by now). It could make 802.11 calls when you are near a base station and cell phone calls when you are not.
Anything that pushes the expansion of the 802.11 network is cool with me!

Prior art can't be just an idea described in, say, an SF novel with no details of how it works. For example, if someone comes up with an inertialess drive, nothing that E.E. Smith wrote would invalidate a patent on it. To get a patent you need to disclose your best preferred embodiment; that is, the best way you know of that the invention can be built or made. Prior art, likewise, has to do the same.
It'd be nice to see a better understanding of how the patent system worked, especially amongst those who flame it at every opportunity!
IANAL, but I *do* write technology patents for a living...

Re:One silly patent we won't have to worry about.. (Score:2)
Obviously my comment was only meant as a light joke, so of course you're right, prior art needs to disclose sufficient detail to invalidate the novelty (or unobviousness) of a given claim.
For the most part Star Trek episodes don't provide a good enough description of the "enabling" technologies to prevent patents in teleportation, for instance. However, certain letters, memos, and works of fiction have prevented (or have been cited by) a number of patents over the years. Arthur C. Clake's famous letter on geosynchronous satellites, and a fictional procedure for raising sunken ships both come to mind.
All joking aside (for a moment), with so many overly broad technology patents being issued these days, I do think that the example of communicators (along with a lot of other prior art) could bear on the novelty and unobviousness of certain broad claims for a wearable, wireless means for hand-free communication. Narrower claims of implementation would obviously be available, as would design patents for form factor.
This is analogous to Clarke's description of Comsats. Although technical (and not fiction), his letter was brief and his inability (in 1945, before orbital launches and transistors) to fully describe or enable his invention would have likely prevented him from receiving a patent on his scheme.
However, his short description was sufficient to prevent Hughes from obtaining broad patents on the geosychronous aspects of their working Comsats in the 1960's. I'm sure that they were able to get numerous patents on more specific details, but Clake's prior art denied them their broadest claim.
Likewise, while Star Trek or Dick Tracy may do little to describe the inner workings of their technologies, I'm sure that certain fictional ideas can (and do) act as limiting prior art, if only in a very broad sense.
IANAL either, but I do have some professional familiarity with the system, and I do not try to flame it at every opportunity (just point out flaws, concerns, and the occasional humour).

Bottom line, a couple of garage tinkerers have managed to extend 802.11b's range to about 20 miles. Big deal, right? We hear about this all the time. The kicker is that they are actually deploying it in some neighborhoods, so it appears to be something real rather than something "we hope to deploy 5 years from now".
We might actually see universal broadband in our lifetimes! (Not that I don't already have a l33t 3 megabit cable modem, but...)
What I especially like about this is that true broadcast broadband would allow a lot of competing providers in each area, instead of needing massive investment in running wires.

That occurred to me, but I would imagine that the cell sites don't have to be 20 miles. If you higher density areas, then you put up higher density cell sites cellular-phone style.
The only question is whether you start getting into huge interference problems at that point. Cell phones seem to have solved these problems, though.

That's true. These things really aim at making wide area coverage feasible, as it won't make financial sense to deploy a WiFi base station every 100 yards in sparsely populated areas.
The only question is whether you start getting into huge interference problems at that point.
As long as everyone behaves and there is some kind of network planning, no. The problem is that WiFi devices operate on unlicenced bands, meaning that anyone who cares can put one up (or hoist a rigged microwave oven up on the roof and just blast noise at you).
Cell phones seem to have solved these problems, though.
Cellular networks operate on strictly regulated licenced bands, which makes it relatively simple to guarantee a certain level of service. Even then there are sometimes problems with capacity planning and radio propagatin in difficult terrain.
Of course, if WiFi access is cheap enough and you don't mind the occasional hickup, you might be fine with it.

Engine room, map/plot room, comm room, etc were all spread out over the ship, with communications between them. In the old old days (sorry) this communication system was just a bunch of pipes one could talk into and sorta hear out of the other side.

It seems like the endgame should be some variant ofUltra Wideband. [slashdot.org] It wouldn't broadcast in all frequencies, just a wide swath of them. Frequencies that had dedicated purposes would be outside this range. This would allow much higher transmitter power, which means longer ranges.
Then let the market jump in. Interference isn't a problem due to lowish power and efficient airwave usage. Let whoever wants to set up base stations. Use p2p mesh networking. Do whatever. The devices are cheap and don't interfere. This may be one of the technology market segments that actually acts like a market.

Most amateur radios and commercial ones to have a ptt (push to talk) button on them but occasionally some people forget the other aspect which i refer to as rtl (release to listen). Since most radios are simplex or 1/2 duplex you need to unkey the radio to hear the other person (and/or make sure they haven't switched frequencies and left).
A trouble w/ a vox circuit in that implimentation will really show up in a mobile environment. if you go past a construction site you will find that instead of the conversation you were listening to, you are now transmitting all the noises arround you.
On a duplex conversation, like a phone, it is always transmitting and recieving at the same time. This has an advantage of you can interupt the other person but there's a tendancy to not pay attention to the other's conversation as the tendancy is to ramble on more instead of shorter messages w/ a pause between.
Additionally for a situation as above like driving by construction some people will forget that they may not be able to be heard over the noise. the natral reaction to that is to talk louder so you can be heard but that only makes things worse. Radios and cellphones have really sensitive micropones these days and talking louder will only distort what you are trying to say.
Digitally encoding a voice for radio communication has been done and is being done by hams, it's not all that new. It is quite possible to send somtihng like that by 802.11 even using existing technologies. Record the voice to a digital format (ie
