The built-in noise filter can effectively reduce noises generated by surrounding electronic equipment such as dryers, vacuum cleaners, lamps or mobile phone chargers plugged into the power outlets to enhance the network environment for multimedia streaming.Powered by the latest IEEE 1901 technology and a Gigabit Ethernet port, ZyXEL’s PLA4215 can provide a stable high-performance network for you to enjoy multiple HD streams, multiplayer gaming and Web surfing simultaneously.The extra power outlet gives you the flexibility and convenience to deploy the home network while providing electricity to other electrical devices.With plug-and-play design, the PLA4215 provides data transfer rates of up to 500 Mbps over power lines with Gigabit Ethernet support.Use your power outlets not only for power, but for enabling stable, high-performance network for video streaming, online gaming and Web surfing on all the network devices throughout your home. The units themselves are large and bulky, but designed so that if you plug them into the bottom socket of a typical duplex wall outlet, you should be able to insert a normal plug into the top socket.Transform your power outlets into a network with ZyXEL plug-and-play Powerline adapters. ZyXEL provides a single, rather skimpy 56-inch ethernet cable for each adapter-you’re on your own when it comes to using the second ethernet port (fortunately, CAT5E cables are very inexpensive). When I paired the Extollo with the ZyXEL, performance dropped by a negligible 6Mbps. I attribute the difference to the presence of noise on the electrical circuit during the second test. The ZyXEL PLA5456 delivered TCP throughput of 350.3Mbps second in our JPerf benchmark tests, which is about 16Mbps slower than the Extollo however, when I retested the Extollo on the same day as the ZyXEL, it delivered the very same average performance. Be sure to shop around, though, as Amazon is charging $130 for the PLA5456. The $90 LANSocket 1500 kit is a little cheaper than the ZyXEL-which NewEgg is selling for $100-but that’s not an unreasonable premium for the utility of that second ethernet port. Both adapters have a pass-through electrical outlet, but the ZyXEL offers one feature the Extollo does not: A second ethernet port. As a result, consumers have little or no assurance that different models of HomePlug AV2 MIMO products will work well together even if they’re from the same manufacturer.Īs for the product in hand, ZyXEL’s PLA5456 is equally as fast as the Extollo LANSocket 1500, our reigning powerline speed champ, which is also based on Broadcom’s AV2 MIMO chips. It seems it can’t even protect its own HomePlug branding. In short, the networking industry has made a mess out of the powerline networking market, with the HomePlug Alliance getting wrong pretty much everything the Wi-Fi Alliance got right.
