This book provides descriptions of the key types of wireless systems along with explanations of their functional parts. You will discover how mobile radios (subscriber stations), base stations, wireless networks and gateways work together to provide communication services. The fundamentals of wireless technologies and their terminology are described along with how the radio frequency spectrum is divided, the basics of radio frequency transmission and modulation, antennas and radio network operation.

You will learn about the different types of mobile telephone systems including cellular telephone, land mobile radio (LMR), cordless telephony and wireless PBX (WPBX). Explained are the key types of wireless personal area networks (WPANs) including Bluetooth and UWB. Discover how wireless LANs such as 802.11 WLAN are evolving to offer ultra broadband data transmission speeds.

Learn how and why broadcast television, radio broadcast and wireless cable TV systems are transitioning from in way analog systems to two-way digital multimedia communication systems. Descriptions of paging systems are provided and you will discover how paging systems are evolving from one-way numeric messaging to two-way interactive information services. The key types of satellite systems are covered including GEO, MEO and LEO systems.

An overview of fixed wireless systems including point to point microwave, wireless cable, and broadband wireless is included. Discover how WiMax systems operate and how it can provide data transmission speeds up to 155 Mbps at distances of 15 km or more.

Mobile Radio Functions

This diagram shows a block diagram of a mobile radio transceiver. In this diagram, sound is converted to an electrical signal by a microphone. The audio signal is processed (filtered and adjusted) and is sent to a modulator. The modulator creates a modulated RF signal using the audio signal. The modulated signal is supplied to an RF amplifier that increases the level of the RF signal and supplies it to the antenna for radio transmission. This mobile radio simultaneously receives another RF signal on a different frequency to allow the listening of the other person while talking. The received RF signal is then boosted by the receiver to a level acceptable for the demodulator assembly. The demodulator extracts the audio signal and the audio signal is amplified so it can create sound from the speaker.

Bluetooth System

This diagram shows Bluetooth devices that have created temporary connections. In this diagram, the personal digital assistant (PDA) device is synchronizing (deleting, changing, and adding) addresses with a laptop computer. The laptop computer is also connected to the Internet through a Bluetooth enabled access node. A mobile phone is also synchronizing its phone book listing with the laptop computer. However, because it is out of direct range of communicating with the laptop, it communicates through the access node. The mobile phone is also communicating with a wireless headset.

Mobile Telephone System

This figure shows a mobile telephone system. The wireless network connects mobile radios to each other or the public switched telephone network (PSTN) by using radio towers (base stations) that are connected to a mobile switching center (MSC). The mobile switching center can transfer calls to the PSTN.
