The networking company D-Link expand its portfolio of wireless routers for digital home with a new device class. DIR-815 provides in practice two wireless networks with their ability to work simultaneously in two frequency bands – 2.4GHz and 5GHz, and thereafter to maintain capacity for data transmission with up to 600Mbps. The router is based on 802.11n technology 2×2 external antenna, which provides higher speed and wider range of coverage at the same time is compatible with existing 802.11a / g wireless devices. D-Link DIR-integrated into its popular 815 and energy saving technology Green Ethernet. The router has 5 Fast Ethernet ports (4 LAN and 1 WAN), which actively monitor the status of the devices included therein and save electricity by automatic activation of standby.
DIR-815 is certified and fully ready for future migration to IPv6. On the box, users will find the logo IPv6 Ready Gold, which means that the router not only supports Internet Protocol Next Generation, and is compatible with other IPv6 devices, including other manufacturers. The device is designed for home users who want maximum bandwidth, advanced functionality and capabilities to support multiple devices in a wireless network. D-Link believes that dual-frequency devices such as DIR-815 are the future of 802.11n standard, mostly due to the efficient use of 5GHz frequency. It is wider and less traffic than 2.4GHz, which is currently used most wireless devices (including bluetooth adapters, etc.). The 5GHz technology has a significantly more not covering up channels – 23 (compared to 3’s range of 2.4GHz), thus ensuring maximum quality of service and consistent performance of extremely sensitive to traffic applications such as transmission aloud or HD TV in real time.

During the review of HP Pavilion tx1250 I made critical comments to the touch-screen display of the test laptop, which was pretty mediocre sensitivity. On the other hand, HP Media handsome is relatively cheaper and more image-making machine with no claims for professional applications. But today we face a real Tablet laptop with a fantastic resolution and magneto-Electrical outlet down on the screen, and not expensive touch-screen coverage. This expensive laptop, professional, long ago in our point of view “test laboratory”, but due to software “adventures”, putting it into a functioning species will be postponed for nearly two weeks. Prior will say that not too long ago I was so fascinated by computers. Visitors to our show room are also very pleasantly surprised by this amazing machine. Design and housing. Design of the Toshiba Portege M400 is a classic and very reminiscent of that business-series Tecra – classic proportions, no shiny material, excessive thinning, leading to poor cooling. This is a working machine – working for designers, artists, engineers and architects. Workstation for rich design studios, where the cost of machinery is irrelevant. Hinge of the display has a slight clearance (compared to HP Pavilion tx1250), but this is easily corrected with a screwdriver – just these machines are used, although very reserved. Very pleasant impression made solid rubber demferi protecting the display from contact with the keyboard. (more…)
