The decentralized and open characteristic of the internet, along with the mobility and portability of mobile communication, and the interactivity of the internet and mobile communications all have been grafted to enable the creation of wireless internet in our lives, bringing about a lot of change. However, existing system management software solutions show limitations in time and space, as well as problems such as uncertain error messages, and also difficulty providing swift assistance or real time emergency support. Therefore, a wireless remote control system has been designed and implemented in this thesis, which is capable of managing and monitoring remote systems using mobile communication devices (Mobile Phone, PDA, Smart Phone, Webpad) for realtime control. The implemented real time wireless remote control system provides remote server management functions, error or event message functions, log record functions, authentication function via mobile devices and system performance evaluation function classified by client transaction.

This study was performed to avoid the chemical spraying environment condition during spraying operation for operator's safety through the development of a remote controlled speed sprayer. The summerized results of this study are as followings. 1. The developed VHF electric wave remote controlling system which could operate sixteen type of operation conditions with the circuit channels of 234 was highly adaptable to speed sprayer for the remote control. 2. The commerical wireless telephones adapted the DTMF type electric wave remote control system need not the tranceiver. 3. The wireless electric wave remote control system combined with one-chip microcomputer, which are low cost with compact in size, could be adaptable to the remote control of the speed sprayer for the wheel steering and speed control system, and to the remote control chemical application system.

An unmanned speed sprayer was developed using a remote control and an inductive cable guidance systems to protect operators and environment from hazardous pesticides. The sprayer consists of a remote control system, an induction system, obstacle detectors, control actuators and an one-chip microcomputer. The sprayer can be operated by the induction guidance and/or remote control. The following summarize characteristics of the developed speed sprayer. 1) Both the remote control and the induction guidance operation were possible with the developed speed sprayer. 2) Sixteen functions of the forwarding, backing, halting, steering, 3-way valve for nozzles and fan operating etc. were utilized on the remote control system. 3) It was concluded that the DTMF method, having less transmitting error, performed better than the FSK method for an agricultural remote controller. A radio station may be necessary. 4) The digital inductive guidance system, consisting of five low-impedance detection coils and a window comparator circuit, performed better than the analog detecting system, guiding route using inductive voltage differential from tow detection coils.

Remote management and control system for LMDS wireless CATV network which is being developed at SK Telecom is developed. This system is composed of central control division located at head center and remote units for remote transceivers equipped in base stations and repeaters. It monitors the state of the remote transceivers and controls the operations using PSTN for iterface. Remote transceivers whould be equipped in pairs, and the operations are exchanged automatically in case of emergency situations. the remote units are designed not only to perform commands form central control division, bet to inform emergency situations such as disorder and power failure. This system works well, which is established at Central research center in SK Telecom with remote units such as BTX, PPTX, and PPRX. This system could be utilized in other applications requiring remote control through sligh modifications.
