In this amendment to IEEE Std 802.15.4(TM)-2011, outdoor low-data-rate, wireless, television white space (TVWS) network requirements are addressed. Alternate physical layers (PHYs) are defined as well as only the medium access control (MAC) modifications needed to support their implementation.
This amendment provides two PHYs (MSK and LRP UWB) that can be used in a wide range of applications requiring various combinations of low cost, low energy consumption, multiyear battery life, reliable communications, precision location, and reader options. This PHY standard supports the performance and flexibility needed for future mass deployments of highly populated autonomous active RFID systems...
Wireless communication supposed a great both - quantitative and qualitative, jump in the management of the information, allowing the access and interchange of it without the need of a physical cable connection. The wireless transmission of voice and information has remained in constant evolution, arising new standards like Bluetoothtrade, Wibreetrade or Zigbeetrade developed under the IEEE 802.15...
