Combine power feed and data link via cable for remote peripherals
Design How-To 11/10/2011 6 comments
It is possible to combine power distribution and high-speed data transmission by sharing a shielded twisted pair cable. A power feed network is necessary at both ends for power injection and extraction. By properly designing this network, and managing power supply switching noise, performance degradation is minimized.
802.11ac Wireless LAN: what’s new and the impact on design and test
Design How-To 11/9/2011 Post a comment
The first popular standards for wireless LAN (IEEE 802.11a and b), and later 802.11g, were designed primarily to connect a laptop PC in the home and office, and later to allow connectivity “on the road” in airports, hotels, Internet cafes, and shopping malls. Today, there are further usage models that require even higher data throughput to support today’s “unwired office”.
