Walker Telecommunications Corp. has introduced the first
cellular phone small enough to fit into a pocket or purse.
the "Pocketphone" made for Walker by Britain's Technophone
Ltd., weighs 15 oz. and is nearly half the size of competing
models from Motorola and Mitsubishi. Walker says that
physicians and lawyers have been the first to pocket the
$3,295 Pocketphone.
Don't expect cellular phones to get much smaller, however.
Scientists still have not found a way to shrink the
nickel-cadmium batteries that power the phones. The battery,
which allows about 30 minutes of talk between recharges,
accounts for most its weight and 1/3 of its bulk. Another
limitation is physiological: a phone must reach between the
human ear and mouth.
