Matthew S. Gast 曾协助各种组织了解无线网络技术，建设具有扩充性的、基于标准的安全无线局域网络。过去这几年，他自愿在 Interop Labs 担任工程师与讲师，他在那里与许多顶尖的工程师共事，学到了各种先进的网络安全协议并在研讨会中传达给其他与会者。Matthew 参加过的研讨会不计其数，范围横跨各大陆，他在研讨会上所连接过的无线网络比他在撰写本书第二版时所连接过的还多。他在加入目前所任职的无线局域网络系统公司之前，曾在数家网络安全公司工作过几年。

Matthew S.Gast is a renaissance technologist.In addition to his demonstrated expertise on a variety of network technologies,he is relentlessly inquisitive about the interconnected and interdependent world around him.After graduating from college,his interests in routing,security,and cryptography pulled him towards Silicon Valley to participate in scaling the mountainous network engineering challenge called the Internet.In addition to his technology interests,Matthew is a voracious reader on science and economics and a lifelong supporter of the scientific method.
Matthew is also a Registered Patent Agent before the United States Patent and Trademark Office.Patent agents assist in the drafting and prosecution of patent applications,which has been called the most demanding task in the United States legal system by the Supreme Court.Matthew has co-written two patent applications,one of which was for his own invention.

 

 

The animal on the cover of 802.11 Wireless Netowrks:The Definitive Guide is a horseshoe bat (Rhinolophus hipposideros ).This rare and globally endangered species is the smallest of the European horseshoe bats;they typically weigh only 4-10 grams and have a wingspan of 19-25 centimeters.Horseshoe bats get their name from the horseshoe-shaped,leaflike plate of skin around the nose.This nose-leaf helps modify and direct the ultrasonic sounds they emit through their nostrils (a method of sensory perception known as echolocation)to orient themselves to their surroundings,detect obstacles,communicate with each other,and find food.Bats' echolocation systems are so accurate that they can detect insects the size of gnats and objects as fine as a human hair.
Lesser horseshoe bats are found in a variety of habitats,ranging from the British Isles to the Arabian Peninsula and Central Asia,and from Morocco to Sudan.The lesser horseshoe bat was originally a cave-roosting bat,but many summer maternity colonies now occupy the roofs of old rural houses and farm buildings.These bats also sometimes roost in hedgerows and hollow trees.Maternity colonies of 30 to 70 are normal,but roosting mothers have been known to form colonies of as many as 200 bats.Lesser horseshoe bats hibernate,sometimes in large groups,from October until late April or early May.Their winter roosts are usually underground,in caves or tunnels.They hang by their feet with their wings wrapped around their bodies,often in open and exposed positions but rarely in large clusters.
