Data in 4G traffic is centric‚ data traffic channel increase instead of voice traffic channels. In wireless link user demand for services with the implementation of Asymmetric Digital Subscriber Line (ADSL) and fiber optic access system. System designer for wireless communication system need to cope the problemS

1. Who uses ATM/ Networks that support traditional high-throughput data traffic You might say to yourself that Asyncronous Transfer Mode sounds like a great technology‚ but who uses this thing? ATM is a technology that will enable carriers to capitalize on a number of revenue opportunities through multiple ATM classes of services; high-speed local-area network (LAN) interconnection; voice‚ video‚ and future multimedia applications in business markets in the short term; and in community and residential

model divided into layers To make it easier to understand how networks work‚ write protocols for networks‚ and to create standards for networks 13. Why is the TCP/IP considered an "open" network model It is not owned by any specific organization and shares details of how it works with all 14. The function of a Routers in networking is to Move data between separate LAN’s‚ often by linking them to WAN lines in a network 15. What is "Encapsulation" A way to address data to cross over any

Concept/NTC-360 June 19‚ 2011 Fernando Casafranca Here are the short answer responses for the following terms: • Synchronous and asynchronous 1 SYNCHRONOUS Synchronous systems negotiate the communication parameters at the data link layer before communication begins. Basic synchronous systems will synchronize both clocks before transmission begins‚ and reset their numeric counters for errors etc. More advanced systems may negotiate things like error correction and compression.

the following: o On which layers of the OSI model do WAN protocols operate? o What are some of these protocols? o On which OSI layers do switches and routers operate? o If routers reside at more than one layer‚ what is the difference between the OSI layers? When one looks at the seven layers of the OSI model‚ one can determine that layer three is where the WAN protocols operate on. Layer three is known as the Network Layer. The Network Layer performs several routing functions

Singapore or Delhi or Bombay? The answer is No. So we own the LAN infrastructure but we generally lease WAN infrastructure from any third party Service Providers or from a Telephone company. WANs generally carry a variety of traffic types such as voice‚ data and video. Imagine in your office there are 25 telephone extensions. So you have 25 telephone instruments placed on each officer’s desk wired and
