The 450Mbps TEW-773GR from Trendnet is fast.
(Credit: Dong Ngo/CBS Interactive)Before I begin, let me say this one more time: The 802.11n wireless specification (or Wireless-N, which is currently still in draft state and therefore is also known as Draft N) is a wireless networking standard that offers speeds up to 300Mbps. That is a lot faster than the previous and popular specification 802.11g (or Wireless-G) that caps out at 54Mbps. Wireless-N is backward compatible with Wireless-G devices, meaning they can be connected to Wireless-N networks at 802.11g speed.
Now that, though confusing, is all common knowledge. What's not commonly known is that wireless vendors are about to turn Wireless-N up a notch, making it offer speeds up to 450Mbps. At CES this year, I ran into two vendors who showed off their newest higher-speed Wireless-N routers. Those vendors are D-Link, with the D-Link Xtreme N 450, and Trendnet, with the 450Mbps Wireless N Gigabit Router TEW-773GR.
The D-Link N 450 is similar in functionality to D-Link's DIR-855 Xtreme router. The router features Gigabit Ethernet, SharePort technology, and simultaneous dual-band 2.4 and 5GHz performance.
What makes the N 450 distinctively different from the DIR-855 is that it can offer wireless speeds up to 450Mbps. The 50-percent increase of speed is made possible by the latest chip design and faster processor that allow the router to handle three streams of signal per antenna. Most existing Wireless-N routers can handle only two streams and budget ones can handle only one stream per antenna.
The D-Link N 450 will be available around the beginning of the second quarter of 2009. Pricing is not yet available.
Similar to the N 450, Trendnet's TEW-773GR router also supports three high-performance antennas and three spatial streams per antenna. However the TEW-773GR is a single band 2.4GHz-only Wireless-N router. The router is also currently in a prototype state and will be available to the public in the second quarter of 2009. It's estimated to cost less than $200.
Like all Wireless-N routers, these new routers will be backward compatible with all existing wireless clients of the same band (2.4Ghz or 5GHz). In order for the 450Mbps to archive, users will need new clients (add-in cards/adapters) that support this speed.
As the change in speed is not based on a proprietary technology, it's highly likely that the 450Mbps routers and adapters from different vendors will interoperate at this speed, especially when they are Wi-Fi Certified.
The N 450 wireless router from D-Link can run as fast as 450Mbps.

D-Link's Xtreme N DIR-685 wireless router.
(Credit: D-Link)During 2008, I complained about all of D-Link's wireless routers, such as the DIR-825 or the DIR-855 because of their common, old-school, bulky designs. Thursday, however, I was more than impressed by the all-new Xtreme N Storage DIR-685 wireless router.
It's possibly the first router that really offers a lot more than just routing.
First off, the DIR-685 is the first router from D-Link I know of that features the internal antenna design, which is not new, as Linksys and Netgear have done this for a long time. Nevertheless, the DIR-685 is now much more compact and eye-catching than previous generations of D-Link routers.
What makes the DIR-685 unique, however, is the fact that it comes with a hard drive bay that can house a 2.5-inch SATA hard drive, a full-feature NAS system (with support for media servers and BitTorrent downloads), and features a 3.2-inch LCD monitor. The monitor, apart from being able to display the device's status via graphical gauges, can also work as a photo frame, play streamed video, and show weather forecasts and other live streaming Internet content in up to 1.6 million colors.
The DIR-685 uses D-Link Green technology which, according to D-Link, helps conserve energy. It does this by automatically recognizing port activity and cable length and adjusting power usage by consolidating all functions to a single device instead of many separate products, and by using the idle mode that automatically turns off power to the LCD screen.
According to D-Link, the router's wide local-area network scheduler can turn off the router's Wi-Fi module at a preset time, and the power adapter complies with Energy Star specifications. With these features, the router can offer power savings of up to 30 percent over other routers of the same type, according to D-Link.
On its back, the DIR-685 has four gigabit Ethernet ports and one gigabit WAN port. It also sports two USB ports featuring D-Link's SharePort technology that lets them work as networked USB ports, enabling the router to support any USB devices. The SharePort technology can also be found in D-Link's previous router models, such as the DIR-825.
The DIR-685 will be available by the end of the first quarter and is estimated to cost less than $300. I am looking forward to testing one out.

(Credit: Dong Ngo/CBS Interactive)The first NAS server I've run into that features a surveillance system is the Synology DS107+, and I was very impressed. Thursday, D-Link announced two NAS servers that work more like Internet-based surveillance products--or network video recorders (NVRs)--than storage devices. They are the DNS-722-4 and the DNS-726-4.
Both products are based on D-Link's two-bay network-attached storage (NAS) device technology, such as that used in the DNS-323. The DNS-726-4 NVR Pro version works with D-Link, as well as Axis, Sony, and Panasonic network cameras, while the DNS-722-4 NVR works only with D-Link network cameras.
There's one more difference between the two. The DNS-726-4 supports multiple channel playback. The DNS-722-4, on the other hand, supports only one channel.
According to D-Link, the new NVRs can house up to two SATA hard drives in four RAID setups and feature a security lock, 24-7 recording, and a friendly graphical user interface for multiple camera management and for viewing live video or playing back recorded data through the Internet from anywhere at anytime.
While many NAS servers can support Internet cameras to form a surveillance system, D-Link's new NVRs reportedly feature an advanced and flexible event-based management mechanism. The NVRs can monitor all camera events via motion detection or digital input and command different cameras to perform tasks based on certain predetermined conditions. For example, if camera 1 detects motion, the NVR can trigger camera 2 to record, camera 3 to emit light, and camera 4 to turn to the preset position.
Other than that, they both boast the following additional features:
- Smart search: The NVRs' intelligent search function quickly retrieves data by finding a selected area on the video based on preset search criteria (motion detected, object missing, focus lost, camera occlusion, etc.)
- Multiple channel playback (available in the DNS-726-4 only): This means that after selecting the desired video period, the NVR will begin playback and display up to four simultaneous channels.
- Playback speed control: Both NVRs can playback at up to 16x speeds in fast-forward or fast-backward modes. They can also playback video one frame at a time.
- Video enhancement: Users can adjust the recorded video to get enhanced output for brightness, sharpness, etc.
- Camera status display: Both NVRs will produce a status page to show connection, recording, frame, and bit rate information for each camera. Users also can check the display to see how much recording time remain.
According to D-Link, the new NVRs are the only IP surveillance recording and playback management systems that offer advanced functionality and four built-in levels of RAID, as well as up to 120 frame speed performance, for less than $700.
But not by much, the DSN-726-4's estimated price is $699.99, while the DSN-722-4 is $399.99. Both will be available during first quarter 2009.
The SideStage add-in extension monitor from D-Link.
(Credit: D-Link)It's been just two days at CES, and I am already very tired of Alt-Tabbing and looking at my Dell XPS 1330's little screen. I sorely miss my Dell 30-inch UltraSharp LCD at home. Bragging aside, it's really hard to work with multiple little windows on a little screen, especially when I need to look at more than one of them at a time.
For this reason, I was psyched to run into D-Link's newest invention: the SideStage.
Basically, it's a 7-inch LCD monitor that you can plug into your computer via a USB port. The port then both powers and feeds data for the screen to display. Once plugged in, it becomes an extension of the computer's main screen.
The SideStage features 800x480 resolution, with both landscape and portrait modes. Weighing only 1.34 pounds and housed in a sleek black frame, it is 7 inches wide, 4.6 inches tall and only 0.75 inch thick.
The SideStage makes a lot of sense for multitaskers like me. While it's small, it's great for organizing: I can designate certain Windows applications to open only on it, such as instant messengers, widgets, or even our beloved CNETTV.com home page, and leave the main screen of my computer for serious programs like Microsoft Word that I use often. It's really perfect for writers on the go and in this case, unlike with most displays, its small size is actually an advantage.

(Credit: Dong Ngo/CBS Interactive)According to D-Link's representative Les Goldberg, the SideStage is compatible with virtually all CRT and flat-panel monitors, has standard and wide-screen aspect ratios, 32-bit True Color depth for high-quality images, and ultra-low power consumption, which is consistent with the D-Link Green initiative.
Unfortunately, the SideStage will not be available right away for me to use during the rest of CES 2009. I'll have to wait until the end of the year; at that time D-Link will also announce its price.
If it doesn't cost too much, I am pretty sure I'll be (even) more productive next CES.
