Wireless sensor network

fixed interval the PC Master sends request to the Wireless sensor node through the sub master for Data collection. The request send by the PC Master is in the form of frames. The frame which is transmitted by PC master will contain both the sub master id & the wireless sensor node id from where the data should be retrieved. The sub master receives the frame is then check for the wireless sensor node id and then it retransmit to the wireless sensor node as it is. If one of the sub masters become…

Adair, E, and Peterson, R. (2012). Biological Effects of Radiofrequency- Microwave radiation, IEEE Transactions on microwave theory and techniques, Vol 54 (3) Sources of radiations in the modern world include mobile phones, radar installations, transmission pillars, and microwave heaters. These technological developments have made life faster and convenient. The ability to save time had greatly enhanced human capital capacity to be more productive. Adair and Peterson studied different forms of…

(for example by a bathrobe or a blanket), the system fails to work. There are other disadvantages of the IR-based solution: for example the transmitters tend to consume a lot of power so battery life is shortened if transmissions are frequent. • Network-based methods i) IEEE 802.15…

3.8: Benefits and Limitations of RFID: Though RFID is not likely to entirely replace commonly used barcodes in the near future, the following advantages suggest to additionally apply RFID for added value of identification: • Tag detection not requiring human intervention reduces employment costs and eliminates human errors from data collection, • As no line-of-sight is required, tag placement is less constrained, • RFID tags have a longer read range than, e. g., barcodes, • Tags can have…

Wireless technologies have transformed our lives greatly. Until a few years back, we needed a wired computer connected to telephonic ports to get internet access. Nowadays, mobile phones are used for super-fast internet, with applications ranging from banking to movie ticketing. This wireless technology helps reduce cost and also increases mobility. Devices are shrinking in terms of their size and are growing in processing speeds. 4G is the fourth generation of broadband mobile technology after…

To assistance of several multimedia services, have higher data rate to wireless communication system. The necessity of high bit error rate (BER) wireless communication with high channel capacity and reliability, multiple-input multiple-output (MIMO) system is a desired method. In the multifunctional wireless communication application, MIMO antenna system should have compact structure and high isolation [2]. Numerous technique have been proposed…

With the development trend of wireless communication, the main application scenarios of D2D communication in 5G network are as follows: Local service Local service generally can be understood as the user side of the business data is not through the network side (such as the core network) and directly for the local transmission. A typical case of local business is the application of social, social characteristics can be regarded as the application of adjacent D2D technology application based on…

Rogers Communications wireless telecommunications revenue are divided into 4 different segments (network, equipment, prepaid and postpaid) (1). The overall revenue for wireless telecommunications at RCI for 2014 is $7.305 billion which is 56.3% of RCI’s overall revenue. The prepaid segment generated $317 million of revenue in 2012 which makes up 2.5% of RCI’s overall revenue (GTF). The postpaid segment of wireless generated $6.402 billion in 2012 which makes up 50.8% of RCI’s overall revenue…

can also track the movement of a vehicle or person. So, for example, a GPS tracking system can be used by a company to monitor the route and progress of a delivery truck. A GPS tracking unit uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction. So, a GPS tracking system can potentially give both real-time and…

BLUETOOTH TECHNOLOGY Introduction As with time, our need becomes our necessity. And it is said that, Necessity is father of all Invention. With time we need wireless technology that can replace cables such as Wi-Fi, Bluetooth. Bluetooth is also cable replacement technology that can connect different computer devices with a short-range wireless radio connection. It has wide areas of applications. Some of it’s features is • Low Complex Architechture, • Power Consumption is low • Less Price •…
