evaluates through different generations: First Generation(1G): First generation of mobile communication developed in 1980 's and completed in early 1990 's based on analog system.1G systems are based on AMPS(Advanced Mobile Phone Service ) technology.1G network only supports voice communication and no data service is provided by this. Second Generation (2G): Second generation of mobile communication was developed in 1990 's based on digital system and speed up to 64 kbps. G provides services such as text
Computer network - a system used to link PCs or computer equipment (servers, routers, and other equipment). For data transmission can be used various kinds of electric signals, light signals or electromagnetic radiation. Computer networks can be classified according to various criteria - territorial prevalence, type of network topology, etc. One of the criteria - the type of transmission, the network is divided into wired and wireless. Wi-Fi - a trademark of Wi-Fi Alliance for wireless networks based
Wireless Communications: Explosive Growth. Explosive growth of wireless communications technology continues as the industry experiences new subscribers and lower prices for services. The U.S. market had 100 million wireless subscribers in year 2000, a 16.2 percent rise from 1999 of 86 million. In 1993, there were only 16 million wireless subscribers, a rise of 525 percent rise in subscribers over 7 years. Market
cellular phones, TV and radio - to create reliable high-speed connections between computers, printers, gaming devices, cameras phones and home entertainment systems. It is not a secret that wireless technology has become the model for entertainment, communication and education all over the world today. Now wireless technologies are very important for us so that we use them in an immense way. Many people all over the world use Wi-Fi in their homes to communicate to anyone with Wi-Fi connected devices
1 SMALL CELL BACKHAUL: Small cell backhaul connects small cells with mobile network operator. As mobile network operators begin to deploy growing numbers of small cells in order to meet the rapidly increasing demand for mobile data capacity, and to utilize the maximum spectrum we use backhaul. The major challenge facing them is how to provide efficient and cost-effective backhaul solution. 2 BACKHAUL REQUIREMENT: For designing this backhaul one should consider the type of environment, transmission
4G Wireless Networks Compare and contrast 3G wireless networks to 4G networks in terms of: 3G and 4G wireless networks can be compared and contrasted by four areas of capabilities: Service and application, network architecture, data throughput and user perception. “Some examples of services offered by 3G wireless networks are CDMA2000 (also known as IMT MultiCarrier (IMTMC), Universal Mobile Telecommunications System (UMTS), and EDGE as well as a long list of others while 4G offer Worldwide
governmental agencies. It offers voice, data and video services and as well as solutions on its wireless and wireline networks. Its market segments thus are made up of Wireless and Wireline. The Wireless Segment offers communications products and services, among them wireless voice and data services and equipment sales that are provided to respective consumer, business and to the government in USA. Verizon Wireless has approximately 112.1 million retail connections. It also provides fourth-generation (4G)
Abstract A Self-Organizing Network (SON) is a compilation of functions (or actions) for the automatic design of communication nodes for optimized performance. Moreover, Self-Organizing Networks are computerized and optimized versions of cellular networks. Capital expenditure, also called CAPEX, is the cost of doing business to create a future advantage. Operational expenditure (OPEX) is the money that a business spends to transform stock into throughput. The self - organization is considered to be
addition, with the development of wireless technology like WiMax, Ad Hoc and WIFI, users may be surfing the Internet much easier but not limited by the cables as before[3]. Thus, those mobile devices have been accepted by more people as their first choice of working and entertainment in their daily lives. This chapter presents a survey on mobile computing, context aware computing, cloud computing .It includes mobile computing architecture ,features,
A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. It is the same as LAN, but has a wireless interface. WLAN utilizes spread-spectrum technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. Wireless Local Area networks (WLANs) have been employed
