Health effects of mobile telephones.

The safety of mobile telephones is a pressing question, now that the brains of nearly half the humans on the planet have become exposed within a short span of time to a physical agent to which their ancestors’ genes could not have adapted. It is no surprise then that epidemiologists have taken an interest in possible health effects of microwave exposure from mobile telephony. Few had experience...

Measurement of the Interference Rejection Capability of Smart Antennas on Mobile Telephones

We are reporting investigations into the interference rejection capabilities of a dual antenna system on a mobile handset prototype for the 1800 MHz band. The performance evaluation is done by using a simulated incoming eld on the handset antennas and by downlink measurements in an indoor environment. Complex signal samples are used in order to investigate the interference rejection gain with d...

Mobile telephones, distracted attention, and pedestrian safety.

Driver distraction is a major cause of traffic accidents, with mobile telephones as a key source of distraction. In two studies, we examined distraction of pedestrians associated with mobile phone use. The first had 60 participants walk along a prescribed route, with half of them conversing on a mobile phone, and the other half holding the phone awaiting a potential call, which never came. Comp...
