thus building trust within the workplace. Verizon Wireless is listed as one of the best companies for workers to seek employment because of this strong model of positive interrelations with its employees, flexible working schedules, and incentives for employees to further their careers (“Working Mothers names Verizon Wireless among 100 best firms,” 2008). By appreciating and encouraging individual interests within the company, Verizon Wireless builds a collective mental model of every worker’s…

Linear Network Coding (LNC) computational complexity makes it unsuitable for practical use in devices that operate on battery power, such as mobile phones and wireless sensors. The triangular pattern based packet coding scheme is performed in two stages. First, redundant “0” bits are selectively added at the head and tail of each packet to make sure that all packets are of uniform bit length. The packets are then…

Even though VANET is considered as a type of MANET, it has its own particular features that make it different from MANET. These characteristics include: 1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m. 2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

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…

high data rate wireless communication, etc. Instead of radio frequency, VLC uses light, to transfer data. The visible light spectrum is unlicensed and 10,000 times larger than the range of radio frequencies. It can be used as an alternate to the existing radio based wireless communication technologies or in hybrid. Moreover, Integrated VLC resolves issue of load balancing in existing wireless…

characteristics of the wireless communication channel. The simplest model is the protocol model in which two nodes can communicate with each other iff they locate in each other’s communication range Rc. Further, in order to capture other disruptive physical characteristics of the wireless channel (e.g., the multiple path fading, and the interference, etc.) rather than only the diminishing effect of the transmission distance, the authors in [Gupta and Kumar 2000] modeled wireless channels…

frequency spectrum resource is utilized. The efficient use of spectrum is analyzed in terms of coverage area, capacity and reuse distance. OFDMA is a very potential multiple access technique, which will be the key technique for the next generation of wireless communications (4G). In this paper the QoS parameters of OFDMA i.e. spectral efficiency [Erlangs/MHz/m2], system capacity is estimated and also compared with the WCDMA. The other important parameters…

We are aiming to develop a device which is useful for both deaf and dump. We introduce a new device “SILENCE BREAKER”. It consist of a Camera, Micro Projector, Mobile computing device and a bluetooth headset. The synchronized action of all these components helps the dump and deaf for proper communication. The Silence Breaker recognizes the gestures of the dump and generates voice signal corresponding to it. In the case of deaf, the device captures the oral sounds and converts to gestures which…

with friends or families. Also, a type of technology that is used frequently is the Internet. The Internet allows people to connect with people and can gain facts that are essential for people to live. Nurse uses technology such as the Internet and wireless devices to communicate in their field. Also, it makes nurses life’s easier than tracking down a colleague to know what to do if something terrible happens such as someone falling of the bed. Besides making the nurses life easier, the…
