In 1940, Austrian-born Hedy Lamarr, considered one of the sexiest actresses of her time, was also a co-inventor of frequency hopping. She, along with George Antheil, an American composer ...

There are various forms of spread spectrum communications. The most popular forms of spread spectrum include frequency hopping multiple access (FHMA) and code division multiple access (CDMA). FHMA is ...

[BeMasher]’s Itron C1SR smart meter broadcasts both interval data and standard consumption in the 915MHz ISM band using a Manchester encoded, frequency hopping spread spectrum protocol.

It's called "frequency hopping spread spectrum," and it all but ensures that your Bluetooth devices can't be hacked – not by way of the Bluetooth signal, at any rate. What Bluetooth is used for ...

Known as "pseudo-random noise codes," Walsh codes are used in direct sequence spread spectrum (DSSS) systems such as Qualcomm's CDMA. They are also used in frequency hopping spread spectrum (FHSS ...
