communications has changed people’s lives over the years. It’s become a fundamental of existence in each home, enterprise, or public spaces such as hospital, educational organization, airport and hotel. The demand of wireless technology drives people to go in depth to understand the fundamentals of wireless and how to improve it to get faster and securer communication. IEEE 802.11, the standard of the wireless communication technology developed by the Institute of Electrical and Electronics Engineers (IEEE) for wireless local area networks (WLANs) between a user and access point (AP), or between two wireless devices. (Intel). It first started by developing a connection between home and the office for local area connection, which give a maximum data rate of 2Mbps per AP which increased to 11 Mbps per AP and known as IEEE 802.11b. After that a newer updated versions came up known as IEEE 802.11g and IEEE 802.11a to provide maximum data rate of 54 Mbps. Furthermore, IEEE 802.11n was a newer version came up after 802.11 a/g to give a data rate up to 600 Mbps. These…
Case Study: New College, University of Oxford New College simplifies wireless access while increasing visibility and security New College was looking for a new security automation and orchestration solution. The IT office at New College realized that although their homegrown authentication and registration solution had succeeded for many years, new security measures were needed because of student-driven demand for campus-wide wireless and wired connectivity. Among other capabilities, New College…
Stakeholder Concerns In order to optimize and upgrade the Leonard Cooper Network, I will have to understand and solve the current concerns of the stakeholders. The results from the interview conducted on four stakeholders indicate that: the existing network sometimes gets congested, collisions proliferate, and the network’s throughput slows down when the teachers report simultaneously on attendance and check emails. The existing bandwidth of the network is 10Mb and the fifty networked printers…
quality video streaming, more advanced client devices, data backup, and VoIP. As 802.11n was the standard wireless protocol to supporting everyday devices and applications, the ratification of 802.11ac has progressed in technology and its impact in wireless networking. Within just three years after the ratification of 802.11ac, this technology has become the new advanced Wi-Fi standard in the wireless ecosystem. Due to it being the most advanced standard available in today’s market, there is…
It indicates the radio frequency band utilized 2.5GHz for IEEE 802.11b, IEEE 802.11g, or IEEE802.11n, and 5GHz for IEEE 802.11a [20]. Most buildings like a University or an office building have already distributed WiFi hotspots that provide whole building coverage as network access point. Devices which employ Wi-Fi technology include personal computers, video-game consoles, smartphones, digital cameras, tablet computers and digital audio players. That the infrastructure cost and user device…
The 802.11 is the standard protocol for wireless networks, which includes WEP (wired equivalent privacy). The standards committee for 802.11 left many of the difficult security issues such as key management and a robust authentication mechanism as open problems. The standards they have established have many flaws that have led to a number of practical attacks. With the increase number of wireless technology there is an increase in the range of places people can perform their business. As a…
When an individual is looked at his/her background instead of his actually ability then there is a strong public response that is stopping the company to pick that individual. Men and women face different barriers when joining non-traditional occupation support. According to the article, “Men: A growing minority?”, the author says that, “Other experts agree that the field needs a diversity of viewpoints, but point out that it 's not only the male perspective that is underrepresented in…
2. The IEEE 802.11n:- The IEEE 802.11n standard, appear in 2008, And become popular because the jump in data transfer rates from about 54 Mbps to nearly 600 Mbps. The IEEE 802.11n standard was officially completed in 2009 but most of the technical features were ratified in 2007. Most companies supported for the creation of a 60 GHz based standard for WLANs to succeed the 802.11n standard, and a lot of attention and effort was devoted to this activity. However, it was soon realized that the 60…
802.7 IEEE 802.7 is a sub-standard of the IEEE 802 which covers broadband local area networks with a coaxial cable. This standard was developed for cable internet companies. e. 802.11 (a, b, g, n) – Wireless Network Standards 802.11 is the collection of standards setup for wireless networking. They include four different standards including; 802.11a, 802.b, 802.11g and the most recent standard 802.11n. Each standard uses a frequency to connect to the network and has a defined upper limit for…
enable network at home or at office. 2. HISTORY AND DISCOVERY OF WIFI Figure: Wi-Fi trademark In 1997, the institute of electrical and electronics engineers (IEEE) develop a set of standards required to setup the wireless communication between computers and pre existing networks including networks at home and office. Wi-Fi has mature and grown immensely fast changing the face of computing and communication in the world. First let we look out the history of…
