4 gigahertz(24 bild)--a similar frequency to mobilphones and microwave ovens As you might know though a frequency this higormorewirelessrouteradvicevisithttp://wirelessrouterdealsorg

means that the wavelength must be very short which is why wireless networkorks oveIn addition ws networksopping They use dozens of frequencies in the range they are given, andconstantly switch between them this makes wireless networks more immune toerference from other radio signals than they would be if they only transmittedon one frequencyAccess Pointshe final stelen it comes to all the computers on a network sharing internetaccess

This is done using a special piece of wireless equipment called an accessoint Access points are more expensive than wireless cards for one computer, athey contain radios that are capable of talking to around 100 computers at thesame time and sharing out access to the Internet between them Dedicatedaccess points are only really essential for larger networks, thoughave a few computers it is possible to use one of them as the access point, oryou could just get a wireless routeThey Understand each othewell and good, then but how does wireless equipment made by entirelydifferent companies manage to work together whetWell, the answer is that there are standards that all wireless devices follow Thesestandards are technically called the 802 11 standards, and are set by the I(Institute of Electrical and Electronics Engineersthanks to people stickleir standards that wireless networking is so easy and cheap to use todayormorewirelessrouteradvicevisithttp://wirelessrouterdealsorg
