Edimax EW-7238RPD is a Concurrent Dual-Band Universal Wi-Fi Extender, complies with wireless IEEE 802.11a/b/g/n standards, providing concurrent dual-band wireless speeds up to 300 Mbps (2.4 G Hz + 5 G Hz). When many Wi-Fi devices are operating under the same wireless channel including your neighbor’s 2.4 G Hz Wi-Fi, each device will be queued, which will affect & interfere with your wireless speed so videos will lag. The 5 G Hz frequency band is significantly less crowded than 2.4 G Hz, meaning less interference, less lag & more stable, robust Wi-Fi. The EW-7238RPD can extend your existing 5 G Hz network to dead zones & let your dual-band smartphone or tablet such as iPad, iPhone 5, Samsung Galaxy S Series smartphones, RIM Blackberry Playbooks or Motorola Xooms to name a few, enjoy stable video streaming. Enjoy fast network speeds for streaming intensive media such as HD video or music, for entertainment or gaming. The Edimax EW-7238RPD is compatible with all single or dual-band routers & access points–so you can use an EW-7238RPD to extend the coverage of any network, without worrying about compatibility.
