Wireless network

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…

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…

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…

1) Linked Cluster Algorithm (LCA) [5], [6], [7]: LCA, was one of the initial clustering algorithms evolved. It was primarily developed for wired sensors, but later applied in wireless sensor networks. In LCA, a unique ID number is allotted to each node and has two means of becoming a cluster head. The first way is that if the node has the greatest ID number in the set including all neighbor nodes and the node itself. The second way is to assume that none of its neighbors are cluster heads,…

Plantronics voyager Bluetooth headset When you start searching for wireless headsets on the internet, you would get confused as there are numerous options available. However, if you have the correct priorities, you would be able to choose the correct headset without any kind of problem. Once the factors which you need to hold at the highest level of importance is company reputation. If a headset brand does not have a positive image, do not consider it to buy headsets even if you are getting them…

issues in sensor networks was presented by (Arif Mahmud and Rahim Rahmani, 2011) at the IEEE International Conference on Computer Science and Network Technology while the first architectural proposal was presented by (Luo et al., 2012) in the form of Software Defined Wireless Sensor Network (SD-WSN). Up until now, very limited research work is carried out in this area. Some of the notable, proposed architectures for using SDN in WSN are: • Software Defined Wireless Sensor Network (SD-WSN) •…

Wifi is used all over the world. Every wonder how it was made? Hedy Lamar created frequency hopping in the 1940s which lead to wifi. She created the frequency hopping technique for the navy, but when she explained it to them they said it would never work. So Hedy Lamar gave her patent to the Navy and never earned a penny off her invention. She died at the age of eighty six and did not get much credit for her idea. Now, wifi is used everyday by millions of people. Hedy Lamar made a huge impact in…

External Environment Analysis Analyzing the external environment of Verizon, requires the use of PESTEL and Porter’s five forces model. Threat of Entry: Low threat. New entrants don’t present a problem to Verizon. Establishing a wireless company is expensive, it requires a substantial amount of capital, work and resources, and additionally it requires to comply with government regulations that could take a high number of years to comply with, something that dissuades new comers. Power of…

Internet of Things, also widely referred to as IoT denotes the internetworking of physical devices with software, network connectivity and sensors that enable them to communicate. The physical devices include buildings and vehicles. These physical devices are embedded with actuators, electronics, network connectivity and sensors that enable them to collect and exchange data leading to an infrastructure of the information society. Through the sensors and internet connectivity, Internet of Things…
