SP-PL200 (Powerline adapter) to transmit data over power lines, in line with HomePlug AV, IEEE 802.3, IEEE 802.3u standards. The Powerline adapter provides 200Mbps transfer rate, the internal LAN data transmission more efficient to meet the needs of high-bandwidth applications. The same meter range, 300m transmission distance, long-distance data transmission to meet the demand, not furnished wired networks, cable networks, such as network traces difficult environments, such as hotels, split-level house, can provide no additional cabling solutions using existing power lines for data transmission. Wireless unable to completely cover, there are blind spots or poor coverage of the network environment, such as a large area of houses, apartments, villas, SP-PL200 can serve as a good complement to eliminate blind spots. SP-PL200 connected through power socket and power supply, plug and play, greatly reducing the number and difficulty of network cabling, the network environment is more concise, easier to maintain.
