![]() ![]() Bridges often run at 200 mW to 400 mW of transmit power with omnidirectional antennas that have relatively low gain. The flexibility of this unit might make it a perfect match with metro-scale wireless networks. According to their numbers (15 dBm transmit power and 10.4 dBi antenna gain), it's roughly 25 dBm of effective power output (EIRP) or 350 milliwatts. They also claim about 1,000 feet of range, which, for this gain, is pretty reasonable via line of sight.įor $150, about the price of a bridge, you get a fairly high-gain unit. They say they've seen 30 Mbps over 802.11g at distances where a normal adapter hit just 1 Mbps. The idea is that this is somewhere between a high-gain PC Card or ExpressCard, which is anchored into a laptop and only works with laptops that offer a card slot, and a high-gain bridge that requires external AC power and an Ethernet port. The Lehigh University project turns commercial: The Wi-Fire is a high-gain, directional, external, USB powered-and-attached Wi-Fi adapter with Windows XP support. Posted by Glenn Fleishman at 2:31 PM | Permanent Link | Categories: 802.11n, Adapters, Hardware, Standards | 1 Comment October 17, 2006 Asus, Belkin, Buffalo, D-Link, and NetGear are all part of this first wave of branding. This is clever, because it will go beyond the Wi-Fi Alliance tests, which focus on wireless protocols, and include the whole ecosystem of DHCP addressing and other factors. The announcement includes the Connect with Centrino program, in which access point makers commit to rigorous testing with Intel to ensure interoperability. They will support 2.4 GHz and 5 GHz N channels. They do note that N will provide an hour more battery life under comparable circumstances with the previous Centrino flavor. Like Apple, Intel says five times the throughput, twice the range, but only in comparison with their previous products-no actual specs on megabits per second or feet/meters. The Santa Rosa laptop chipset platform is due in the second quarter of 2007, at which point they expect more participation. Notebook partners include Acer, Asus, Gateway, and Toshiba committed at this point, with systems available at the end of January using Centrino Duo. Apple and Intel have been coordinating messages, and even though Apple won't be using Intel's chips-Atheros appears to be the anointed party-Intel wanted to wait until after the IEEE task group vote last week and after CES, too. On the heels of Apple's commitment to 802.11n, Intel gets in the act: The timing is no coincidence.
