Sample text

The PHY may or may not include electromechanical devices, but in essence, it is the brains of the radio. Basically, the PHY’s job is to transmit bits of data over a communication medium in either digital or analogue form. It makes no difference as to what those bits represent; the PHY operates in the same way regardless of the type of data. Physical-layer specifications typically define characteristics such as voltage levels, the timing of voltage changes, data rates, maximum transmission distances and physical connectors.

Several companies have even demonstrated this capability in the form of prototypes or proprietary modes. Ultrawideband has yet to explore the known options for improvement, such as higher-order modulation, antenna diversity or intelligent antenna structures to improve its performance. When this is done, it is reasonable to expect UWB throughput to grow substantially, with a realistic peak level expected to be between 2–5 Gb/s. 2 Low cost The second principal asset that UWB has to its credit is very low cost.

Other wireless technologies, UWB appears to be equivalent or possibly at a disadvantage. However, a radio’s effect on a battery is not only a question of the maximum amount of power that it draws at any given instant. It is also a question of how long the radio must be on to perform a given transfer. In the case of UWB, while the peak power is relatively high, for the transmission of a given amount of data the radio transmits for a much shorter period of time relative to other radios because of its very high throughput rate.
