During summer nights, theres nothing worse than a swarm of
mosquitoes. But, now those lousy days are coming to an end because
hi-tech cell phones can help users repel mosquitoes.
SK Telecom, Koreas top mobile operator, said it will introduce the
extraordinary downloadable content service starting July 14.
The service, which costs 3,000 won per download, generates
anti-mosquito sound waves to control mosquitoes within a range of
one meter.
Customers can wirelessly download the content from the companys
website.
The mosquito repelling service uses a particular spectrum of sound
waves, which are undetectable by human ears. But the frequencies
annoy mosquitoes, SK Telecom said.
A disadvantage is that the service takes up more battery power, but
customers can effectively use the service with rechargeable
equipment.
