Powered by the latest IEEE 1901 technology & a Gigabit Ethernet port, Zy XEL's 500 Mbps Powerline Gigabit Ethernet Adapter can provide a stable high-performance network for you to enjoy multiple HD streams, multiplayer gaming & Web surfing simultaneously. With a pair of plug-&-play PLA4205 installed, you can easily extend your home network through any electrical outlet for Internet access by HDTVs, Blu-ray players, DVRs, PCs & game consoles. The advanced Quality of Service (Qo S) features improve the quality of multimedia streaming applications such as Triple Play services, HD video streaming, high-speed Internet access & Vo IP. When there is no Ethernet link, the PLA4205 will enter a power-saving mode, reducing energy consumption by around 80% when compared to adapters without this function. Data transmission is protected by 128-bit Advanced Encryption Security (AES) security to provide a secure connection to the Internet. Encryption can be configured by a simple button press on both of your PLA4205s; there's no complicated setup or software required to be run. Please note: networking components such as Powerline adapters require that all adapters must work within the same Home Plug standard to remain compatible, for example Home Plug AV (HPAV) adapters with communicate with other HPAV Powerline components, regardless of whether they are 200 Mbps or 500 Mbps. Older 85 Mbps adapters work on the different Home Plug 1.0 standard & are not compatible with Home Plug AV adapters. All Powerline products will connect to any switch or router Ethernet port. Powerline adapters can be used with extension leads (except surge protection ones), & will work across different ring mains so long as they share a common fuse box.
