Rural wireless telemetry for ambulance, police, education, etc.

By wallowamichael ·
Our small town is building a new hospital. We are designated as a critical care site, since we have an airstrip and the next nearest care facility in any direction is a two-three hour drive.

One of the people involved in the construction has come up with grants that would provide mobile telemetry for the ambulances. This means that pulse, blood pressure, respiration, and other medical information could wirelessly be beamed to the ER before the patient arrives and the ER would be better prepared to care for the patient.

Here's the question -

Are any of you involved in something like this? If you are, HELP! There is so little information readily available, and salespeople are not much help. I've tried calling support numbers and getting answers 'from the trenches' about installations and possible problems, but not having much luck.

What I have found out is most of the equipment is 900Mhz or 2.4Ghz, but we have TONS of 2.4Ghz Motorola mesh type wireless already running in town (another ISP) - is it going to interfere? And what about 2.4Ghz phones?

We're considering mobile WiMax, but the specification is still being hammered out, and nothing is available.

Our one concern is coverage. The hospital (and schools) don't have access to put up mesh radios wherever they want, so we have to either pay, or find long range mesh radios to put in the areas we do have access to.

Anybody know anything about mobile WiMax? I've seen 6Mbps data rate with a range of 5 miles, that would be perfect, except nobody will quote it right now until the 802.16 spec comes out.

I probably should have blogged this rather than discussed it, but ANY comrade feedback would be appreciated.

A little help

by jmgarvin In reply to Rural wireless telemetry ...

You might want to post this in Tech Q&A.

As for some basic info:
A) Since everything seems to operate at 2.4ghz, I'd suggest looking at what does and what channels you are using. If you have a free couple of channels, then you should be good to go.

B) I'm not keen on WiMax, but I haven't implemented it either. You'll have to talk to somebody who has installed and configured it.

C) What kind of radio system are we talking about? I'm kinda assuming FM, but you started talking about a radio mess for all the emergency services...What where you looking at implementing? I can tell you that Santa Fe has wireless data transport to Albuquerque (about 70 miles as the crow flies) and it is just now being utilized. Is that what you are looking at?

As far mobile WiMAX is concerned it is expected become available at the end of 2008, as revealed by Intel.
What type of equipment are you using for communication, whether the mesh network you are going to create would be a sensors network , or you will use antennas and specific WiMAX cards. May be i can help you in your project. Also please tell me whether WiMAX protocol is implementable on sensors or not.
