Michael Lewis (2000: pages 256-257) scoffed at the whole attempt to formalize the definition of business models when he wrote that " "Business Model" is one of those terms of art that were central to the Internet boom: it glorifies all manner of half baked plans. All it really meant was how you planned to make money." In an abstract of his paper "A Mesoscopic Approach to Business Models: Nano Research on Management" published in "Economic Issues in China" Dr. Junyi Weng stated that "Business

Rivalry Among Competitors In 2005 Saudi Arabia became a member of WTO and opened up the Saudi Telecommunications market to foreign competitors. The Saudi Arabian Telecommunication market has become increasingly competitive. In addition to competing on prices all the major competitors are striving to offer differentiated products and services aimed at increasing their market shares. The competition is apparent in the decline in STC’s income despite higher revenues. Table 1 – Level of Competition

[prev] [prev-tail] [tail] [up] Chapter 4 Fading and Shadowing Fading is a significant part of any wireless communication design; it is important to predict what type of fading may occur‚ and if possible use a wireless standard capable of providing remedies for the fades. When no remedies are possible‚ it may be important to predict the likelihood of outage. We will review here several types of fading and provide models to predict their impact. 4.1 Large-Scale Shadowing We start with

Because of these properties‚ MIMO is an important part of modern wireless communication standards such as IEEE 802.11n (Wifi)‚ 4G‚ 3GPP Long Term Evolution‚ WiMAX and HSPA+. MIMO technology leverages multipath behavior by using multiple‚ “smart” transmitters and receivers with an added “spatial” dimension to dramatically increase performance and range. MIMO allows multiple antennas to send and receive multiple

A mobile phone (also known as a cellular phone‚ cell phone‚ and a hand phone) is a device that can make and receive telephone calls over aradio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator‚ allowing access to the public telephone network. By contrast‚ a cordless telephone is used only within the short range of a single‚ private base station. In addition to telephony‚ modern mobile phones also support a wide variety
