Wireless Access Points: Power over Ethernet

PoE gives you the freedom of installing wireless access points anywhere a ethernet cable will go. Before power over ethernet was available a wireless access point always had to be near a power outlet to give it power. This meant more money and usually bad placement.

PoE uses a device called a power injector to transfer the correct amount of power required to run the wireless access point. PoE uses the two unused wireless in a ethernet cable to run the power. Gigabit ethernet uses all the wires in an ethernet cable thus PoE is not available for Gigabit ethernet. Each client device that meets the standards of the PoE 802.3af amendment will be assigned a power class of 0-3 which will mandate how many watts they need. Often your wireless access point will be managed by a switch that will double as a PoE injector.

wireless access point placement is a major key for good security, both physical and wireless. If you are using a Fat access point which is located near a common power outlet or easily in reach of employees all it takes is a paper clip to reset the access point and your network has been hacked. Also placement is a major concern because if you install a wireless access point on the perimeter walls of you office you have just sent half you signal out side to the war driver passing by.

Remember when coming up with your wireless network budget do not let anyone say we dont need PoE. Compromising on placement of your access points will cost you security and money in the long run.

Nintendo Wii Brings The Gym to You With Wii-Fit

Nintendo has announced a new fitness game Wii Fit which is a full on exercise product set to give you more of a workout than Wii sports, while still retaining all the fun of gaming. Wii Fit will help to keep you physically fit via a dedicated peripheral, a wireless balance board which comes with the game. There are over 40 different activities, including hula hooping, ski jumping and heading soccer balls.

The hula hooping consists of, as youd expect, gyrating your hips with a virtual hoop onscreen and then as the game progresses, characters will throw more hoops for you to catch and rotate as many times as you can until the time runs out.

The skiing game gives you two chances to make the longest jump you can whilst keeping your balance when landing. Players can increase speed by leaning forward, the more you lean the faster youll go, and upon reaching the jump, you stand up straight ensuring your weight is evenly balanced for a good landing.

For the football game, you will need to balance on the board moving from side to side whilst balls are fired at you to hit back on to the field and avoiding other objects that are thrown at you at the same time.

training falls into 4 categories: aerobics, muscle conditioning, yoga and balance games. Players can assign their height to a profile to measure body mass index and Wii fitness age as well as monitor progress and record performance statistics.

The calorie busting fun could appeal to couch potato kids as well a non gamers, perhaps using the Nintendo Wii as a slimming tool which would be a move into the lifestyle category rather than gaming, covering the market from another angle.

Nintendo has not given a release date yet for Wii Fit, although its thought to hit the highstreet in early 2008.

Skiers Endure Warmest Winter

Unseasonably warm weather in Europe's Alps left skiers and snowboarders waiting to scratch their winter itch this year. Central europe experienced its warmest winter in 500 years and the Alps had not been so warm in over a millennium. ski resorts are suffering, as are sports enthusiasts.

Half of Switzerland's ski regions are facing a lack of snow as a result of global warming, according to the Organisation for Economic Cooperation and Development (OECD). Europe's famous Alps didn't have enough snow for Christmas skiing in 2006, and the Swiss ski team even had to leave for canada in search of whiter pastures. The Central european winter tourism industry is suffering, and the future does not look white for an industry that depends on snow levels. The German ski industry will likely be hit the hardest by the lack of snow due to with many of its ski areas making due low lying Alpine foothills.

"A one degree Celsius increase would reduce snow by ten per cent and plus 4C would halve the number of snow-reliable slopes in Switzerland," according to a OECD report. The OECD report says lower-lying ski areas in the Bernese Oberland, central and western Switzerland were likely to be the most affected. More than 50% of the slopes in these regions would still be snow-reliable with a 300-metre rise in the snow line. The higher altitude regions in Graubnden and Valais snow line would rise 600 metres but would remain around 80% snow-reliable.

The ski industry is going green to help offset the pollution that feeds global warming. ski resorts very existence are at threat with later snowfalls and earlier snow melts. Some resorts are even attracting tourists for hiking holidays. The weather has even been too warm for snow generating machines because the snow melts as soon as it hits the ground.
