Through this case study I am going to be investigating the different wireless communications that are available, and also how they could benefit Staffordshire Health Authority. I will look at previous and current wireless standards, their differences and the speeds they can provide. I will also consider the best standards to use when working with a network to support VoIP (Voice over Internet Protocol). Throughout the case study I will talk about the technologies that could work within our network environment, and others that would not be suitable or effective. Finally I will look at VoIP and how it will impact on Staffordshire Health Authority.
Discussion of Wireless Communications
When looking at wireless communications, there are many standards to discuss as there are so many types all used for different purposes. I am going to talk about a range of communications used for different ways to communicate; for example Bluetooth can be used to send files between mobile devices. Cellular broadband, which is used on mobile phones and tablets to be able to access the internet while out of reach of a Wi-Fi signal. I will also look at satellite, which can be used to provide Internet to remote areas and Wi-Fi which is widely used to access Internet and local networks without having to have a physical connection. I will finally assess WiMAX (Worldwide Interoperability for Microwave Access) that is used to provide Internet over a large distance.
Bluetooth was an IEEE (Institute of Electrical and Electronics Engineers) 802.15 standard, but the standard is no longer sustained. Bluetooth supports speeds up to 24mb/s as well as different power ranges, which allows it to travel over certain distances. Short range can travel 10cm, and then t...

...k, or it could be highly used and cause a great deal of strain on the network, resulting in upgrades needing to be made to cabling and equipment to handle the larger amounts of data travelling over the network.
When looking at the best standards to use for VoIP it is important to make sure the quality of the call is sufficient to be used in a business environment. For example if setting up a wireless based VoIP system you would need to make sure you’re using 802.11n or 802.11ac to ensure the bandwidth is able travel to reduce lag and jitter during the call. Also, when setting up a wired based system you will need to make sure you have a high-speed backbone to your network from the point of the switch managing the VoIP calls. This can be enabled by using gigabit links and also making sure you are using Cat 6 cabling to further reduce jitter, lag and dropped packets.
Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Our primary measure of value for this project will be in increasing use of the internet on the go for our employees by giving them direct wire-less internet service in their vehicles. The addition of wireless Internet service will provide on the go service to better assist with customer service and improve the quality of work for our employees. The added value of employee productivity while using the wireless service on their mobile devices and in vehicles will be difficult to measure, but using surveys to further measure the success of this project.

WiMax has the potential of replacing cellular networks, copper wire networks used by telephone companies, and the coaxial cable infrastructure use by cable TV while offering Internet Service Provider (ISP) services. Relevance of trend: Broadband wireless access (BWA) and in particular WiMax is being
The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.
The high level of capital required building a wireless and wireline infrastructure makes economies of scale or on densely populated areas essential to telecom

technologies such as Bluetooth and ZigBee which are used to carry the information from perception devices to a nearby gateway based on the capabilities of the communicating parties. Internet technologies such as WiFi, 2G, 3G, and 4G carry the information over long distances based on the application. Since applications aim to create smart homes, smart cities, power system monitoring etc.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.
Wireless is everywhere today whether at home working from your WIFI network to work where you might be linked a wireless network or even through your phone through a 3G or 4G network to connecting to an open wireless networks. As you can see for the most part people are connecting to wireless from the moment they leave their home till they get to work and then back. While wireless comm...
Information and Communication Technology (ICT) has been shown to be increasingly important in the education or training and professional practice of healthcare. This paper discusses the impacts of using ICT in Healthcare and its administration. Health Information technology has availed better access to information, improved communication amongst physicians, clinicians, pharmacists and other healthcare workers facilitating continuing professional development for healthcare professionals, patients and the community as a whole. This paper takes a look at the roles, benefits of Information and Communication Technology (ICT) in healthcare services and goes on to outline the ICT proceeds/equipment used in the health sector such as the
My mobile phone network coverage allows me to make a call wherever I want, and the call is never cut off by the network. Independent surveys show that it has the best signal quality with excellent call clarity. The network covers 99 percent of the population, and it has installed more transmitters than any other digital network company. They guarantee that they work the best; in fact, they will even add a free minute of talk time if the call is ever lost. International and off-peak calls are the cheapest in the area. The company has been voted number 1 in customer satisfaction for 5 years in a row.
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
