we are right now working on project in which we want to transmit the ecg from the patient's bad to the doctor's computer via wireless connection. right now we are searching for the wireless modules which can fulfill this requirements.

Range should be :100m

Rate of data transfer : 2500bits/s for one module

No of patients:Max.10

should be data safe transfer.

please if you have any suggestion regarding this please do contect me here or you can mail me on ravi_bm_87@yahoo.co.in

thanks for your interest

Dear Ravi,

It just occurs to me that you could use wi-fi. I use a hub that can handle traffic from 4 laptops working within a radius of 100 meters.

I surmise that you should be able to find a hub that can handle 10 or more laptops as in airports, hotel lounges or other public spaces that are wi-fi enabled.Instead of laptops, you can hook up wireless ecg transmitters.

Hope this meets your requirements.

During composition of my response to you,CR4 generated the following :

"Would you say that your comment is "off-topic" with respect to the original Forum Thread?

These posts are ok (to a point), but it is considered polite to check this box so that those who want to stay "on-topic" can do so easily. (You may find that your comments will be marked as off-topic by the community anyway, so why not save us all the trouble.) " Yes, this comment is very likely to be considered to be 'off-topic'.

Am I off topic?

Best of luck.

@ramakrishna,

thanks for the comment but as our product is going to be used in the hospital and patients are going to wear the product so i think we will try to find something which will be more light weight and portable....do you think wifi will be a good option....?we are right now looking in the features of bluetooth ,...so if you have any other suggestion, u r always welcome

@Ravi

Bluetooth is meant for closely placed peripherals to communicate with the computer wirelessly.I wonder if it can serve for 100 meters.Wi-fi is very light without the laptop.It's a wireless Modem.

A word of caution: Any radio communication can affect pacemakers and other similar devices.Heart is also susceptible to wireless interference wrt rate of beating of the heart and all equipment working in close proximity to patients have to be certified for RFI and EMI (Radiofrequency Interference, Electromagnetic Induction).

Orlando Regional Medical Center and MD Anderson Cancer Center are using exactly what you are trying to do.

You DO know that there are already such items on the market, right? See http://www.mortara.com for example.

Whatever you do. It doesn't matter if you use wifi or bluetooth. any of those could work after more investigations, but a major problem you would face would be high-frequency noise usually power-line interference and EMG disturbances (tremor) and it will be worse depending on the distance or how far the doctor is from the patients device. There was a recent article on that at BioMed Central : http://www.biomedical-engineering-online.com/content/7/1/29

I use to design Cardiac Pacemakers and this interests me. I would look into a FM transmitter and transmit to a digital FM receiver. They make very small stereo transmitters with PLL technology to prevent Freq. drift and hang a wire from it for the antenna and you will have a (2) channel telemetry system. Transmit V/F from a instrumentation op amp to pick up a noise free signal an amplify it to the proper level and run the freq into one of the channels. Use the other channel for something else like heart rate. Hey I might do this since I am familiar with ECG interpretation! Thanks for the idea!
