D. Wake et D. Moodie, PASSIVE PICOCELL - A FUTURE INTEGRATED WIRELESS COMMUNICATIONS NETWORK, British telecommunications engineering, 16, 1997, pp. 106-112
The demand for wireless services is expected to grow at a terrific pac
e over the next decade. Traditional ways of satisfying this predicted
demand are expensive and inflexible. The passive picocell, a radical n
ew concept invented at BT Laboratories, could provide an integrated wi
reless network using radio base units that are low-cost, small and unp
owered.
