A Nokia sale of mobile, especially to the US, would be nuts
Nokia's hiring of Intel's Justin Hotard to be its new CEO has set tongues wagging again about a mobile exit, but it would look counterintuitive and inadvisable.
The City of Calgary buys the first links using FSO and millimeter wave systems from Terabeam, with up to 20 links on the horizon
January 6, 2003
SEATTLE -- The City of Calgary, a large Western Canadian metropolis known for using technology to advance local government services, has purchased the first links using free space optics and millimeter wave systems from Terabeam in what the City estimates will become up to 20 wireless links to connect City offices and staff. The relationship with Terabeam began when officials of the Canadian city sought a way to connect one of 175 outlying city government buildings to the communications network at Calgary City Hall. Terabeam linked the two buildings with an invisible light beam carrying data at one thousand megabits per second using a pair of Terabeam MagnasTM. That one gigabit connection is the equivalent of 660 T-1 lines. The beam is transmitted from a Terabeam transceiver inside one building, through the office window, through the air, through another building's window to another Terabeam transceiver several blocks away. With the success of that link, the City sought new ways to wirelessly link other city buildings and provide further city services at high speed. Three of the new connections will be made with six Terabeam EllipticasTM, small free space optics transceivers that provide fiber optics-like connectivity to various municipal locations. Two more links will utilize four Terabeam Magnas, the same kind of larger transceivers that the city has already deployed. The city will also use two Terabeam GigalinkTM millimeter wave systems to route the signals from Calgary's digital network of traffic cameras. Once those first two traffic links are completed, the city will identify the locations for future installations to complete the traffic network. Depending upon the design, the network will require 40 or more Terabeam Gigalinks. "We are very pleased with the quality and reliability of Terabeam's equipment," said Ingy Randhawa, manager of Calgary's IT Architecture Office. "Our initial link provides service for city employees in our water works and sewer departments. These groups now operate as if they were in City Hall. With that success, we are now linking many other locations to achieve the same result we did in this first deployment." Terabeam Corp.
