Major Contributers to the Wireless Telecommunications Association

In 2012, Apple sold approximately 125 million iPhones, accounting for more than half of the company's earnings. The company has no debt and is not affected by the financial impact of interest rates. According to Taube (2013), Apple's value is $ 98.3 billion, first ranked among the world's most valuable brands after last year's ranking rose 129%. A potential threat to Apple is to maintain the growth of the global smartphone market. According to BI Intelligence and Apple, the iPhone sells a number of products, but sales growth is different from the smartphone market (Ballve, 2013).

The telecommunications market can be broadly divided into two divisions. The first is wired communication and the other is wireless communication. Wireless communication is currently the most popular technology from its simplicity and sportiness. Regular wired landline phones, cable television cable networks, and wired network connections are major versions of cable telecommunications products. Meanwhile, wireless Internet connections such as mobile phones, Wi - Fi technology, and general wireless services are important examples of wireless telecommunication systems.

Wireless operation allows impractical or impractical services to be performed using wires such as telecommunications. This term is used generically in the telecommunications industry and refers to a telecommunications system (eg, a radio transmitter and a receiver (eg, a radio transmitter and a receiver) that uses some form of energy (eg, radio waves, acoustic energy) to transmit information without using wires Machine, remote control, etc.). . . In this way information is transmitted over short distances and long distances

Wireless networks are a way to avoid expensive processes as homes, telecommunications networks, and commercial facilities for introducing cables into buildings or as connections between various device locations. Wireless communication is typically used to implement and manage wireless telecommunications networks. This implementation is done at the physical layer (layer) of the OSI model network structure. For terrestrial microwave - terrestrial microwave communication, we use transmitters and receivers on the earth as well as satellite antennas. The ground microwave is in the low gigahertz range that limits all communication lines. The relay stations are about 48 kilometers (30 miles) away
