Today we have 802.11n wireless networks with up to 150 Mbps data rates but still we hardly see wireless implementations as an alternative to wired LANs. Why? Is it because wireless networks are unreliable? Or is it because of the data rates?
May be it is because many organizations have wired LAN infrastructure already implemented and not willing to invest on wireless LANs. But what if you want to expand your local area network? Will it not be cheaper to expand using wireless LANs? Whichever the case, in this book I try to give an insight to designing and implementing a wireless LAN. This was done as an assignment when I was at university three years ago so the devices and prices may have changed.
