Cebit: D-Link launches wireless-n routers

Router manufacturers prepare for 802.11n

A wireless-n access point and a quadband wireless-n router, which both transmit at 5GHz, are the latest additions to D-Link's family of 802.11n products, announced at the Cebit trade show.

802.11n is still under development, but if everything goes as planned, it will be ratified by the end of the year or early in 2009. The biggest benefit will be more bandwidth, over 100Mbps.

Today, almost all wireless products transmit at 2.4GHz. That frequency is used by a range of devices, including Bluetooth, which impairs performance. Using 5GHz will improve both stability and scalability, according to D-Link.

The first of the two products, the Wireless N Access Point (or DAP-2553), was developed for the small office/home office market. It supports power over ethernet, and can segment the network using multiple service set identifiers (SSIDs).

The more interesting of the two products is D-Link's Quadband Wireless N Router - or DIR-855. What sets the router apart is that it can handle 802.11n at both 2.4GHz and 5GHz simultaneously, while still supporting existing standards. The 'Quadband' moniker comes from the fact that it can do all this at once.

For instance, the 5GHz band could be used to distribute video while the user surfs the internet over 2.4GHz, without the two uses affecting each other.

The router is also equipped with five Gigabit ethernet ports and an organic light-emitting diode (OLED) network activity display. The router will ship in May.
