Bluetooth & Cordless Phones Interference

Bluetooth will operate at the 2.4GHz range. Few analog or
FH cordless phones have designed to operate at the 2.4GHz band. Certainly
interference exists in between, but more serious effects would be exerted
on analog 2.4GHz cordless phone.
However some other results can be obtained from testing of Aironet
(Cisco), Lucent LAN and WAN 2.4 GHz wireless equipment. This equipment is
not bluetooth nor FH but both products fail when using Panasonic's
cordless phones anywhere near the equipment. The vendors have no solution.
It appears likely that the 2.4 GHz phones will replace the 900 MHz and
will be everywhere. You can buy them at Wal-Mart now, they have much
better quality and range than the 900 MHz. The phones render our wireless
equipment useless.
Bluetooth though is designed to operate in a noisy frequency
environment, by using constant frequency hopping. It would be expected
that any interference would be intermittent. |
