Many people are aware that wireless household appliances like microwave ovens, cordless telephones, and baby monitors can interfere with Wi-Fi wireless network radio signals. But does Wi-Fi also generate interference back in the other direction? Brian Dipert at EDN recently found that having a Wi-Fi router located too close to a DECT 6.0 base station seems to cause degraded voice quality on the cordless phone.
Fortunately, the solution seems to be a simple as keeping a few feet or meters of distance between your home router and any other wireless home equipment. (Note that this may also be a special case as DECT 6.0 utilizes a different set of radio frequencies than most other types of cordless phones.)
