Informatics A high speed LAN hardware standard for communicating among PCs, which can link up to 1024 nodes in a bus network. See Local area network, Packet swltching. Cf Fiber distributed data interface.
With up to 90 W of power available, compared to the 30 W provided by the IEEE 802.at standard (PoE+), IEEE 802.3bt can provide both power and connectivity to new applications that would otherwise require a dedicated and typically off-line power source.
In order to meet this need, studies have chosen to improve the IEEE 802.11e MAC layer of WMM ad hoc networks, seen the ability of MAC protocols to contribute in improving both traffic performance and energy efficiency .
The research conducted in  concluded that despite its low transmit power and simple modulation technique, IEEE 802.15.4 shows a robust behaviour against interference of other 2.4 GHz systems and even in the worst case conditions for frequency overlap, local distance and high traffic load for interference, some time slots remain for a successful transmission of IEEE 802.15.4 traffic.
The new Wi-Fi offerings comprise IEEE 802.11b/g Wi-Fi modules with the company's free source-code TCP/IP stack running on a PIC microcontroller, as well as XBee footprint-compatible socket modules with integrated stacks.
