Wireless communication technology

Contactless communication techniques have been developed using mainly electromagnetic waves in several frequency ranges, propagating in the air. Examples of wireless communications technologies are Wi-Fi and FSO, whose importance and...

A WLAN is a ubiquitous and broadband wireless resource that uses low-bandwidth channels that meet the requirements for reliable and robust communication with speeds of up to 54 Mb/s. It is developed between sensors and gateways that are scattered at a distance of 30—50 m indoors or 100—200 m outdoors. WLANs are deployed over urban, suburban, and mral environments, and the main wireless communications technology is Wi-Fi, usually covering two bands, one in 2.4 GHz and one in 5.2 GHz. 

In this chapter the use of WSNs for the monitoring of various sporting activities of an athlete has been studied, with the main focus on the selection of the optimal wireless communication technology for the interconnection of the (vital) signs and sensors worn by athletes. For this reason, the performance characteristics of various modem wireless communications standards and technologies were presented.

Double resonance techniques, on the other hand, of which the earliest was ENDOR (described in Chapter 1), have greatly benefited from advances in signal processing technology, of the sort now employed, for example, in wireless communication systems.

Digital management of hidden danger mode, in the already built information management platform of cod mine enterprises has been widely used. At present, the underground wireless network communication technology has been mature, relying... 

Several drivers lie behind this pattern. Eor telecoms, the need to issue substantial amounts of long-term debt reflected the vast technological changes that swept over the industry at the end of the last millennium. The rapid spread of wireless communications led to the wave of partly debt-financed mergers among the major telecom service providers. In order to...
