Bluetooth 's Speed And Coverage Range

Cell phones have changed the communication game forever, for better or for worse. With the presence of cell phones, distance is no longer a communication barrier. Talking to family thousands of miles away can now be done with the touch of a few buttons. The cell phone has brought the world closer together than it ever has before, and it is arguably the most unique technology humans have ever created. Many past creations have had comparisons, such as cars to horses and airplanes to birds. In contrast, “nothing in the animal world could allow humans the power bestowed by the cell phone” (Katz 1). There is no animal with the ability to communicate with another animal across thousands of miles within seconds. The cell phone is unlike anything we have ever created, and it is creating opportunities we never could have dreamed of.

I. Introduction: What if every cell phone in the world crashed? How would society communicate? How would one know when someone’s birthday is without getting a notification for it? Some people wouldn’t even know when to get up each morning. Thirty years ago, these questions would be easily answered, but it would have taken separate resources to solve each issue. Most tasks nowadays, however, are done by using this single device. The overuse of cell phones in modern day society has caused quite

The functional requirements of the BS is a data communication with Tier 1 devices, sufficient computing power, and \ac{WAN} accessibility. In most of the research, however, a single computing device with a network tool for the Internet or combined device configuration, such as a PC with a gateway or wireless router, and smart phone, has used as Tier 2 system due to its simplicity and effectiveness \cite{leijdekkers2008self, jin2009hearttogo, monton2008body, pandian2008smart}. The modern wearable and mobile devices, such as a smart watches and smart phones, can be employed as a \ac{cDAQ} in Tier 1 due to it has enough computing power and storage capacity to handle the data, as well as a \ac{BS} of Tier 2 when they support the Internet connection

Bluetooth is designed to operate in an environment of many users. Up to eight devices can communicate in a

Bluetooth was invented in 1994 that replaces cable communications with wireless technology. (Ericsson, 1994) Bluetooth creates a wireless personal area network (PAN) that allows exchange of information among individuals and therefore is commonly used for short-range communication among mobile phones, laptops, PDAs and other portable and fixed devices. (Layton & Franklin, [date unknown])

This shows one of our first steps to becoming hands free. Now, I don’t think that we will ever be completely hands free but with my set of Bluetooth headphones, I have the capability to call from them and talk through them without having to touch my phone that’s pretty hands free! This type of device can make our everyday lives easier and better or just more enjoyable by driving,commuting to work, going on a run, workouts, chores around the house or just for fun! Most can be used for multiple things like gaming, music and recording. These, I am sure would be looked at like basic headphones in the future, but i hope it will show where some of their new gadgets started from and give new ideas to the next generation of

Bluetooth technology was the creation of the Bluetooth Special Interest Group. This groups was founded by five major corporations from different countries to develop communication system that could be used world-wide. Ericsson, Nokia, IBM, Intel, and Toshiba, founded the Bluetooth Special Interest Group (SIG) in February of 1998. (Morrow, 2002) Microsoft, 3Com, Lucent, and Motorola later joined the group in December 1999. Now the group of nine members is called SIG Promoters. There are no plan as of now to add any other member to the group. (Morrow, 2002)

The field is of developing significance because of the expanding dependence of PC frameworks in most societies. Computer frameworks now incorporate a wide assortment of "keen" gadgets, including cell phones, TVs and little gadgets as a major aspect of the Internet of Things – and systems incorporate the Internet and private information systems, as well as Bluetooth, Wi-Fi and different remote system.

Under this, there are eight goals. The first goal is support for data and voice by the air protocol. Secondly, it has the ability to create ad hoc connections so that Bluetooth devices can detect the available devices surrounding them and establish connections. The third goal is the ability to withstand. Another

So when I was in preschool, we had this gadget that allows us to communicate even though we are far from each other. It was similar to what Alexander Graham Bell invented where in it had two tin cans and was connected by a string. The string was able to transfer sound waves back and forth the tin cans. So then I had an interest of having my own gadget during those days. Later on, I owned my first gadget when I was 7. I had Nokia 3310 back then. It was a basic phone that mainly functions for communication. It was simply used to have an ease when it comes to communication. Then after, improvements were made and they were able to make a lighter one. Not only having it lighter but they were able to project colors other than black and white in the gadget’s screen which is similar to what I had when I was 9. It was a Motorola WX265 which is basically a flip phone. Also they were capable of allowing the sharing of files wirelessly between two phones with the help of Bluetooth and they were successful in installing MP3 systems inside a phone. At the same

frequency offsets in the subcarriers, the orthogonality among the subcarriers breaks and this causes intercarrier interference (ICI). The second drawback, is that

Bluetooth and Wi-Fi are two branches of the same tree. They only differ in the way they are used. Bluetooth is used to transfer data between devices, which are placed near to each other, without the use of cables. Terminology of Wi-Fi is quite the same but the range of distance between the devices could be quite large. A typical Wi-Fi network that is being used in a household could have a range of 200m but a Wi-Fi network that is being used by a business firm could transfer data in several kilometers.

The companies of computer science and telecommunications needed to develop an opened, low cost interface to make easier the communication between devices without using cables. This is the origin of the technology which key name is "Bluetooth". This is a fact nowadays, but now another problem arises and is that there are a lot of standards and technologies, incompatible between them. What we need now is a universal, valid device for the connection of all kinds of peripheral, and that works in a transparent way for the user. This is Bluetooth.

It is no doubt that almost everybody hears about IP address. Nowadays it is widely spread all over the world. IP address is shortened form of Internet Protocol (IP) address. A TCP/IP network is identified by IP address for device or computer. Internet and devices are connected with each other through IP protocol with sending information to each of them IP address. The IP address is not in computer, router, it is in field of interface. Nowadays we have got two types of IP address. These are IPv4( fourth generation of Internet protocol) and IPv6( sixth generation of Internet protocol).

This become difficult when other close by devices are also using that frequency. Using Bluetooth, poses potential security problems because it is less secure comparatively. A range of attacks, such as packet injection, can undermine Bluetooth broadcasts.
