interoperable connected objects with radio-frequency identification (RFID) technology (Li , Xu , & Zhao, 2014). The words “Internet” and “Things” means an inter (Gartner, 2016)connected world-wide network which is based on sensory, communication, networking, and information processing technologies which can be a new version of information and communications technology (Li , Xu , & Zhao, 2014). As per (Yiu & Yau ,…

comparing Li-Fi and Wi-Fi considering various aspects. LI-FI is a visible light technology to achieve high speed wireless communication by using visible light to transfer data. It acquired this name due to its similarity to WI-FI which utilizes radio waves for transfer of data. WI-FI is great for extensive wireless coverage in buildings but has severe limitations for high density wireless information coverage in limited space and has radio waves interference issues; While Li-Fi greatly…

large portion of the global communications infrastructure is represented by wireless technology, it is vital to understand overall broadband trends and the role between wireless and wire line communication technologies. Several times both wire line and wireless technologies competed with each other, but generally, they are complementary to each other. For the most part, core infrastructure and backhaul transport for wireless networks are based on wire line technologies, whether copper wire or…

The important characteristics of IR is that it can’t penetrate walls or other opaque materials. Typically, with an IR-based system, a receiver is placed in every location in which a tagged device might be found. The tagged device emits IR light, and if the tagged device is in the same room as a receiver its position is known. The major advantage of an IR-based system is that as the oldest and most installed positioning technology, solutions are generally available from a variety of sources…

When the iPhone was launched, BlackBerry had a better quality phone on the market and had larger sales in the market and great brand reputation but soon they were falling due to the lack of marketing. BlackBerry spent and continues to spend significantly lower amounts ($41.3 million) on marketing, about 10 times lower than Apple ($400 million) and 8 times lower than Samsung ($334 million) in 2012 (Bennett, 2013). While BlackBerry shares something in common with Apple that their devices are ran…

in other regions. ZigBee is used for long distance transmission between devices in wireless mesh network. It has low cost, low data transfer rate, short latency time, comparing to WiFi standards. The technology uses the RSS method to estimate the distance between two or more zigbee sensor devices[36] . 2.5.3 Short Distance Wireless Technology 2.5.3.1 Bluetooth Bluetooth is intended to enable short range wireless communication between devices. Bluetooth communicates utilized radio waves with…

As a Telecommunications Network Specialist with many years of experience, I have identified three trends notably buzzing and propelling technology overdrive. These trends are the implementation of Cloud Computing/Networking, Radio and television (analog to digital migration), and the innovation of 5G Network infrastructures. Industry codes for the following telecommunications branch are NAICS: 51791, 517312, 515111 and Research codes: ISO 15-1143.01…

1.1 WIRELESS SENSOR NETWORK (WSN): Wi-Fi sensor networks (WSN), once in a while called wireless tool and actuator networks (WSAN), are spatially disbursed autonomous sensors to monitor bodily or environmental situations, which include temperature, sound, pressure, and so forth. and to cooperatively pass their expertise through the network to a major location. The extra brand new networks are bi-directional, additionally sanctioning control of device activity. The improvement of wireless…

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…
