Definition of "Broadband Over Power Line" |
Broadband over power lines is a method of power line communication that allows relatively high-speed digital data transmission over the public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range and different technologies from other forms of power-line communications to provide high-rate communication over longer distances. BPL uses frequencies which are part of the radio spectrum allocated to over-the-air communication services therefore the prevention of interference to, and from, these services is a very important factor in designing BPL systems. / The term hot carrier refers to either holes or electrons also referred to as 'hot electrons that have gained very high kinetic energy after being accelerated by a strong electric field in areas of high field intensities within a semiconductor especially MOS device.Because of their high kinetic energy, hot carriers can get injected and trapped in areas of the device where they shouldn't be, forming a space charge that causes the device to degrade or become unstable. The term 'hot carrier effects', therefore, refers to device degradation or instability caused by hot carrier injection. |
