The intelligent lighting control system is one of typical applications of the Internet of things. The method of intelligent lighting control system based on industrial wireless technology is proposed in the paper. It used proposed three-point-control technology, and adjusting the brightness of lamps, turn on/off the lamps and a part of fault detection can be realized. At the same time, it can greatly reduce the cost of system. It will be useful to engineer and researchers.

Wireless networks offer mobility and elimination of unsightly cables and utilize radio waves or microwaves to maintain communication. It is rapidly growing in popularity for both home and business networking. Wireless technology keeps on improving and at the same time the cost of wireless products are continuously decreasing. The demand for ubiquitous personal communications is driving the development of wireless networks that can accommodate mobile voice and data users who move throughout buildings, cities, or countries. The objective of this chapter is to provide the fundamentals of wireless networks so that the general readers can be able to easily grasp some of the ideas in this area.

This research studies the effects of wireless mobile phone technology on technology transfer and economic growth, and its distributional consequence in Nigeria. After deregulation of telecom industry, wireless technology has become widely available in Nigeria  The current study argues that the availability of wireless technology helps to reduce the cost of learning and implementing world technology frontier and thus that it promotes smoother transfer of technology from technologically-advanced countries to Nigeria and brings significant growth in the economy. Using a multi-sector Schumpeterian growth model, thus, it explains the relationship between the cost of technology transfer and economic growth. The model generates two equilibria where the low equilibrium has zero growth. This study shows that a group with low cost of technology transfer is likely to achieve the high growth equilibrium while a group with high cost of technology transfer is likely to achieve the low growth equilibrium. Using the industry-level and the state-level data, the study found that the availability of wireless technology increased transfer of technology measured by the volume of imports and spurred growth in Nigeria. Moreover, the research found that the benefit of the wireless technology is greater for lower income groups and thus the technology helped to reduce distributional inequality of economic benefit.

In large numbers of the industrial sectors, wireless networking technologies are acquiring rapid endorsement on account of their cost-adequacy, improved unwavering quality, and adaptability. A wireless network can be characterized as a network of devices, meant as hubs. Their essential usefulness is to corporately detect, accumulate, measure, and distribute data in the general climate. Wireless methods communication without the utilization of wires other than the recieving wire, the Ethernet, and the ground replacing wires. For a few industrial activities, wireless technology bears the cost of savvy and compelling availability arrangements. Utilizing wireless technology there are numerous advantages, for example, distant offices, cycles and field activity which brings about improving productivity, personal time, quicker and more accurate data assortment.

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

The imaging performance of the light optical lens systems has reached such a degree of perfection that nowadays numerical apertures of about 1 can be utilized. Compared to this state of development the objective lenses of electron microscopes are rather poor allowing at most usable apertures somewhat smaller than 10-2 . This severe shortcoming is due to the unavoidable axial chromatic and spherical aberration of rotationally symmetric electron lenses employed so far in all electron microscopes.The resolution of such electron microscopes can only be improved by increasing the accelerating voltage which shortens the electron wave length. Unfortunately, this procedure is rather ineffective because the achievable gain in resolution is only proportional to λ1/4 for a fixed magnetic field strength determined by the magnetic saturation of the pole pieces. Moreover, increasing the acceleration voltage results in deleterious knock-on processes and in extreme difficulties to stabilize the high voltage. Last not least the cost increase exponentially with voltage.
