Wireless technology is one of the most common technologies used in our day to day life. As wireless technology is very much easier to implement rather than wired, day by day its application is increasing. Through the continuous development of wireless communication technology it is now highly used in wireless equipment controlling. That is we can control our electronics and electrical equipments from a certain distant part. In this paper a multipurpose radio controlled car is designed with nRF24L01 wireless transceiver module, Arduino Uno R3 and DC motors to monitor risky areas.

This work aims at developing wireless communication medium a mid two nodes by using Encryption and Frequency Hopping techniques. Data Encryption is done by using Cryptography. One of the major challenges in data communication network is security. This issue becomes more critical if there is connectivity during resource sharing. In our paper, we discuss data encryption using RSA algorithm to make certain that data is confidential. Using this algorithm, sender is allowed to generate public keys to encrypt the information and receiver is been shared with a private key using a protected database to decrypt the same. An erroneous private key will decrypt the protected data but to a different form from the actual data. The data we choose for being a key, method of distributing it are vital issues in algorithms. Hence Cryptography is used to convert the message block into a private key and Frequency Hoping is done by using the Spread Spectrum technique. Also the classification of cryptographic algorithms is outlined in this paper.

Wireless data communication technology under industrial environment is a new development trend in recent years, applying wireless technology to the field of data collection can solve problems and shortcomings caused by wired network, such as cabling, faulty inspection difficulties and so on. Safe operation of mine hoist matters much to the safety of mine production. As a result of the lack of detection measures hoist overload occurs from time to time, it poses a greater threat to safety in production. Combing sensor technology with emerging wireless communication technology, the wireless data transmission technology program that takes P89LPC935 MCU as cored controlling component is designed and provided in this project, constructing a new type of real-time monitoring system for main shaft hoist load.

Spatio Temporal

The efficiency of wireless systems to transmit information in a complex interference situation is one of the main indicators of the effectiveness of the system, which can be characterized by the probability of an error in the transmitted message. This characteristic depends on the interference situation of the communication channel and the nature of the signals propagation in the medium. If the medium has a multi-path character, the signal interferes with the receiving antenna, causing signal fading. So the developer of wireless communication devices is faced with the task of increasing the noise immunity of the system. It can be increased in various ways, for example, by using adaptive processing algorithms for spatio-temporal signals. In this paper we solve the problem of improving noise immunity in wireless communication systems by applying an algorithm of adaptive spatial-temporal signal processing in the receiver based on an adaptive antenna array, which allows spatial filtering under conditions of a complex pattern of signal propagation in a channel with reflections. Calculation of weights for the adaptation algorithm in the article is based on the theory of eigenvalues and vectors of the spatial correlation matrix.
