Some products that claim to shield the user from RF
absorption use special phone cases, while others
involve nothing more than a metallic accessory
attached to the phone. Studies have shown that these
products generally do not work as advertised.
Unlike “hand-free” kits, these so-called “shields” may
interfere with proper operation of the phone. The phone
may be forced to boost its power to compensate,
leading to an increase in RF absorption. In February
2002, the Federal trade Commission (FTC) charged two
companies that sold devices that claimed to protect
wireless phone users from radiation with making false
and unsubstantiated claims. According to FTC, these
defendants lacked a reasonable basis to substantiate
their claim.
9. What about wireless phone interference with
medical equipment?
Radio frequency energy (RF) from wireless phones can
interact with some electronic devices. For this reason,
FDA helped develop a detailed test method to measure
electromagnetic interference (EMI) of implanted cardiac
pacemakers and defibrillators from wireless telephones.
This test method is now part of a standard sponsored
by the Association for the Advancement of Medical
instrumentation (AAMI). The final draft, a joint effort by
FDA, medical device manufacturers, and many other
groups, was completed in late 2000. This standard will
allow manufacturers to ensure that cardiac pacemakers
and defibrillators are safe from wireless phone EMI.
FDA has tested hearing aids for interference from
handheld wireless phones and helped develop a
voluntary standard sponsored by the Institute of
Electrical and Electronic Engineers (IEEE). This
standard specifies test methods and performance
requirements for hearing aids and wireless phones so
that no interference occurs when a person uses a
compatible phone and a compatible hearing aid at the
same time. This standard was approved by the IEEE in
2000.
FDA continues to monitor the use of wireless phones for
possible interactions with other medical devices. Should
harmful interference be found to occur, FDA will conduct
testing to assess the interference and work to resolve
the problem.
