Wireless is a technology that transmits signal without using cables as the medium to communicate from one end to other(s) end. Communications via wireless can be anything from radio broadcasting, SOS signal from a ship at sea, or day-to-day Wi-Fi that we use to connect to the Internet. Actually wireless technology is a technology that already been in development for quite a long time, it developments already begun since late 19th century. Here is the timeline of the development of wireless technology:

#1 The concept of a wireless network is to be able to provide a broad range of coverage to a large geographical area wirelessly (Techtarget, n. d.). Further, a wireless network gives one an advantage to connect wirelessly to other devices in separate areas of coverage. In healthcare, a wireless network is used to improve access, reduce errors and deliver an accurate healthcare information anywhere and at any given period among patients and healthcare providers (IEEE, 2003). Mobile devices, such

COOPERATIVE COMMUNICATION Background We have introduced a new form of diversity for the concept of mobile communications system of cooperation. Cooperation by mobile phone users for each user is assigned. Cooperation can be considered as a new form of space diversity, antenna diversity in the transmission process, however, and other complications, Intermobiles noisy channels, each phone has sent a separate message. (W. Yu and T. Lan, 2007, pp. 2646–2660) According to A. Goldsmith (2005), wireless communications

their role.” • Inadequately secured wireless communication “Wireless security isn’t just a big issue for control systems, but for all uses, mainly because wireless is becoming so pervasive,” says Staggs. “It’s very easy to plug wireless in almost anywhere. However, you have to be able to find the signals and know if someone has put in a rogue point. “Before installing wireless, it’s important to do a complete assessment to identify the best areas for wireless use and ensure that leakage out of the

on all preceding generations of mobile communication along with fifth generation technology. Fifth generation network provide affordable broadband wireless connectivity (very high speed). The paper throws light on network architecture of fifth generation technology. Currently 5G term is not officially used. In fifth generation researches are being made on development of World Wide Wireless Web (WWWW), Dynamic Adhoc Wireless Networks (DAWN) and Real Wireless World. Fifth generation focus on (Voice

technologies and newly emerging concepts, the assumption and context may be broken by services provided by modern mobile devices equipped with various sensors and powerful computation-power, such as smart phones [4]. The advancement in mobile devices and wireless technologies has enabled the provisioning of services more flexible and diverse [5-7]. On one hand, The manufacturers of mobile devices have recently achieved break-throughs to extend mobile devices’

How is Bluetooth a modern technological application of physics? Introduction Bluetooth was invented in 1994 that replaces cable communications with wireless technology. (Ericsson, 1994) Bluetooth creates a wireless personal area network (PAN) that allows exchange of information among individuals and therefore is commonly used for short-range communication among mobile phones, laptops, PDAs and other portable and fixed devices. (Layton & Franklin, [date unknown]) Physics plays an important
