Through this case study I will look at the different wireless communications available and also the benefits they could bring to the Staffordshire Health Authority. I'll 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 technologies that might work in our network environment and others that would not be suitable or effective. Finally I will look at VoIP and its impact on the Staffordshire Health Authority. Wireless Communications Discussion When considering wireless communications, there are many standards to discuss since there are so many types all used for different purposes. I will talk about a series of communications used for different ways of communicating; for example Bluetooth can be used to send files between mobile devices. Cellular broadband, used on mobile phones and tablets to be able to access the Internet when the Wi-Fi signal is not reachable. I will also consider satellite, which can be used to provide Internet in remote areas, and Wi-Fi, which is widely used to access the Internet and local networks without having to have a physical connection. Finally, I will evaluate WiMAX (Worldwide Interoperability for Microwave Access) used to provide Internet over long distances. Bluetooth used to be an IEEE (Institute of Electrical and Electronics Engineers) 802.15 standard, but the standard is no longer supported. Bluetooth supports speeds up to 24 MB/s and different power ranges, which allows it to travel certain distances. The short range may travel 10cm, so t...... half the paper ......k, or it may be heavily used and cause a large strain on the network, resulting in the need for upgrades to cables and equipment to manage the greater quantities of data traveling on the network. When looking for the best standards to use for VoIP, it is important to ensure that the call quality is sufficient for use in a business environment. For example, if you are setting up a wireless-based VoIP system, you should ensure that you use 802.11n or 802.11ac to ensure that the bandwidth is able to travel to reduce delay and jitter during the call. Additionally, when setting up a wired system, you need to make sure you have a high-speed backbone to the network from where the switch handles VoIP calls. This can be enabled by using gigabit links and also making sure to use Cat 6 cabling to further reduce jitter, delay and lost packets.
