Wi-fi devices to call doctors

Labels: ,

Bluetooth has revolutionised the way people communicate. The technology that permits you to use a hands-free device while making calls from mobile can also act as a lifesaver by dialling for your doctor in case of an emergency.

Ofcom, the British communications regulator, predicts in its report "Tomorrow's Wireless World", that sensors could be implanted into people at risk of heart attack or diabetic collapse that would allow doctors to monitor them remotely.

If the "in-body network" recorded that the person had suddenly collapsed, it would send an alert, via a nearby base station at their home, to a surgery or hospital. However, Ofcom also gave warning that the impact of such technology on personal privacy would require more debate, reports the Times.

Not only in case of emergencies, the technology, which is being tested now in Portsmouth, could also be used if a patient failed to take his or her medicines. A pill dispenser would send an automatic reminder and, if the pills were not taken within a certain time, an alarm would sound and a message would be sent to the patient's family or carers.

However, health experts say that they are sceptical about the level of take-up of "in-body" sensors while research into the possible radiation impact of wi-fi networks is going on.

The Ofcom report also said that advances in GPS positioning and short-range wireless technologies could "revolutionise the way we conduct our journeys and safety levels on the roads".

Intelligent transport systems being developed by car manufacturers allowed cars to communicate with each other and send alerts about sudden braking.

If a collision happened the car's system could automatically call the emergency services. The technology could also apply the brakes automati-cally if it was determined that two cars were getting too close to each other.

Paramedics attending the scene of an accident would carry a small computer that would pick up wireless messages from a bracelet incorporated in the driver's watch. These would enable them to gain access to information about the person's medical history, boosting his chances of survival.
