WAN Technologies - POINT–TO-POINT
WAN technologies are based on serial transmission at the physical layer. This means that the bits of a frame are transmitted one at a time over the physical medium. The bits that make up the Layer 2 frame are signaled one at a time by physical layer processes onto the physical medium. The signaling methods include Nonreturn to Zero Level (NRZ-L), High Density Binary 3, (HDB3), and Alternative Mark Inversion (AMI). These are examples of...

Router and Routing Basics - Routing and Routing protocols
Routing is the process that a router uses to forward packets toward the destination network. A router makes decisions based upon the destination IP address of a packet. All devices along the way use the destination IP address to point the packet in the correct direction so that the packet eventually arrives at its destination. In order to make the correct decisions, routers must learn the direction to remote networks. When routers use dynamic...

The handbook of optical communication networks
These factors are leading towards an integrated high-speed (and high-bandwidth) communication environment where all communication needs will be supported by a single communication network. The latest trends indicate that bandwidth needs double every 100 days. The volume of data traffic has surpassed the volume of voice traffic. Such a monumental demand for bandwidth can only be met by using optical fiber as transmission media. Other...

Satellite Networking Principles and Protocols
Satellite has played an important role in telephony communication and TV broadcasting services since the birth of telecommunication satellites. It is less known that satellite also plays an important role in broadband and Internet services and will continue to play an important role in the future generation networks. This is due to the satellite characteristics that make a niche position for satellites in the global network infrastructure...

The surefire way to get ahead is to think ahead. So, while you are working in the here-and-now (whether revamping a client’s Web site or upgrading the client’s supply chain), there’s no time like the present to examine technologies that haven’t been widely adopted but could have a huge impact on enterprises during the next 10 years. Take wireless data networks, for instance: Anywhere, anytime access to corporate data from your...

Wireless securrity and privacy
This book provides wireless and security professionals with a foundation on which to design secure wireless systems. Most security problems are handled reactively rather than proactively; this does not have to be the case for wireless security. In the past decade, advances in software development have outpaced advances in software security.

Radio frequency integrated circuit design
Radio frequency integrated circuit (RFIC) design is an exciting area for research or product development. Technologies are constantly being improved, and as they are, circuits formerly implemented as discrete solutions can now be integrated onto a single chip. In addition to widely used applications such as cordless phones and cell phones, new applications continue to emerge. Examples of new products requiring RFICs are wireless local-area...
