Hình 2.3. Nhiều điểm truy cập và Roaming Để giải quyết các vấn đề đặc biệt về topology, nhà thiết kế mạng chọn cách sử dụng các điểm mở rộng (Extension Point - EP) để làm tăng các điểm truy cập của mạng. Cách nhìn và chức năng của các điểm mở rộng giống như các điểm truy cập, nhưng chúng không được nối dây tới mạng nối dây như là các AP. Chức năng của EP nhằm mở rộng phạm vi của mạng bằng cách làm trễ tín hiệu từ một khách hàng đến một AP hoặc EP khác. Các...

QUESTION 1: If one of the links to a computer on a physical star topology is served, what will be the result? A. The entire network will stop working. B. The affected link and the adjacent network links will stop working. C. Only the affected link will stop working. D. Only the adjacent links will stop working. Answer: C In the star topology each computer is connected to a central point by a separate cable or wireless connection. Thus each computer has a dedicated link to the network central device and a break in the link between a particular computer...

In the last two decades, wireless communication systems such as cordless phones, paging systems, wireless data networks, satellite-based and cellular mobile systems have been steadily increasing in both popular importance and technological sophistication. The firstgeneration wireless systems were developed in the late 1970s and 1980s and were based on analog technology (such as the Advance Mobile Phone Service (AMPS) by AT&T and Nordic Mobile Telephone (NMT) by Ericsson).

Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. Although the ongoing trend is to adopt ad hoc networks for commercial uses due to their certain unique properties, the main challenge is the vulnerability to security attacks.
