| 22. | Spread spectrum technology increases the phone's clarity and range.
|
| 23. | Sony takes cordless telephone use further with the introduction of its spread spectrum series of phones.
|
| 24. | Spektrum is the original application of 2.4 GHz spread spectrum radio systems to radio control models.
|
| 25. | RPMA is a technology communication system employing direct-sequence spread spectrum ( DSSS ) with multiple access.
|
| 26. | It's basically just spread spectrum for IP networks.

|
| 28. | Other later-generation systems still used frequency-hopping spread spectrum ( FHSS ) technology, but at higher bandwidth.
|
| 29. | The radios use direct-sequence spread spectrum coding, which is managed by the digital stream into the modulator.
|
| 30. | By using scrambling technology-- although not as sophisticated as digital spread spectrum-- they block out most eavesdroppers.
