1.2 Bluetooth application
Bluetooth is designed to operate in an environment of many users. Up to eight devices can communicate in a
small network called a piconet. Ten of these piconets can coexist in the same coverage range of the Bluetooth
radio. To provide security, each link is encoded and protected against eavesdropping and interference.
Bluetooth provides support for three general application areas using short-range wireless connectivity:
Data and voice access points. Bluetooth facilitates real-time voice and data transmissions by providing
effortless wireless connection of portable and stationary communications devices.
Cable replacement. Bluetooth eliminates the need for numerous, often proprietary cable attachments for
connection of practically any kind of communications device. Connections are instant and are maintained
even when devices are not within line of sight. The range of each radio is approximately 10 m, but can be
extended to 100 m with an optional amplifier.
Ad hoc networking. A device equipped with a Bluetooth radio can establish instant connection to
another Bluetooth radio as soon as it comes into range.
1.3 Bl uetooth Standards Documents
The Bluetooth standards present a formidable bulk—well over 1,500 pages, divided into two groups: core and
profile. The core specifications describe the details of the various layers of the Bluetooth protocol architecture,
from the radio interface to link control. Related topics are also
Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:
Bluetooth also uses a wireless technology that enables communication between compatible devices. Bluetooth uses a standard 2.4 GHz frequency what allows all Bluetooth-enabled devices to be compatible with each other.
Provides great flexibility as it allows sharing of documents with other devices such as printers in other rooms, uploading files to a desktop computer from a cellphone wirelessly and allows for online streaming.
“Tethering” is the sharing a smartphone network connection with another device and allow connections to the Internet via the other device’s connection (Hoffman, 2013).Tethering is frequently used to access the Internet on a laptop using a smartphone data connection (Hoffman, 2013). One item that most people do not realize is they can also tether over Bluetooth and this will consume much less battery power than Wi-Fi would (Hoffman, 2013).
Party Plates Company has established the need for a new proposal with wireless technology. Team B will research some marketing tools that will assist Party Plates in meeting their goals of advancement in sales and certain goals. This proposal will focus on wireless technology that will be beneficial to the party plate business. Team B will also provide the pros and cons to these wireless technologies and justification of the choice to incorporate them into Party Plates Company. In the proposal, Team B will also include a spreadsheet presenting the equipment needed for using the technologies and the costs
A networking framework in which devices communicated with each other by first going through an Access Point (AP). In infrastructure mode wireless devices can communicate with each other or can communicate with a wired network. With one AP is connected to wired network and a set of wireless stations it is referred to as a Basic Service Set (BSS). An extended service set (ESS) is a set of two or more BSSs that from a single sub network. Most corporate wireless LAN operates in infrastructure mode because they require access to the wireless LAN in order to use services such as file services or printers. A cellular network or mobile network is a wireless infrastructure base network distributed over land areas called cells.
Once the embedded system is up and running, the user has to pair the android smart phone with the HC-05 bluetooth module. For the pairing process between the android device and Bluetooth, run the application and click on connect option. From the drop down, search for a new device, Bluetooth module will appear as HC-05 , add the module to pair. The BT passkey is 1234 .If the paring is done and outcome is listed as “connected to HC05”, then the pairing is successful. If the android device is ten meters away from the device, the outcome is “not connected” and the pairing is failed.
In comparison to other radio systems, multi-site trunked radio systems provide the best coverage. Multi-site
An access point is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.
reach longer ranges. Through gateway devices, it is possible to connect the wearable devices on
This report fulfills the specific requirement for documentation as specified in FIT 5083 Assignment 1. In this technical report, we will identify the various steps and techniques used in deployment of wireless network. Initially, what is networking or network infrastructure? Networking mean to connect two or more devices and configure them in such a way that they can communicate with each other. In networking, network infrastructure means to connect the software and hardware part rather than actual connection between two devices. Now days, wireless network connections are highly on demand because it’s easy to access and it does not require any cabling structure.
Bluetooth is a convenient way of communication in the modern society as it has many benefits for both individuals and companies.
2. What are the three areas defined for the IEEE 802.11 standard? Physical Layer (PHY): The method of transmitting the data, which may be either RF or infrared (although infrared is rarely used.)
Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
In practice, there are some devices on market do not reach devices may reach up to several meter. The normal spot for IrDA communications is from 5cm to 60cm away from transceiver
