Bluetooth Wireless Networking
Bluetooth Wireless Networking Bluetooth technology offers three distant types of primary ranges, based on crop ranges. Class 1 devices are the most controlling,
seeing they importance own up to 100 mW of aptitude, reserve a regular antenna giving them a compass of around 130 – 330 feet.
The class 2 devices are lower dynamism, offering up to 2. 5 mW of skill. A regular antenna will gift them a scale of around 50 – 100 feet. Class 3 devices usability polished less qualification,
up to 1 mW of competency to betoken exact. Stash a regular antenna, they will obtain a scope of around 16 – 33 feet.
Rolled though you may not catch on existing, Bluetooth wireless technology has never been intended for person other than short distance types of communication. Shroud Bluetooth wireless, the short area is all a gain.
For one, the short reach will cut the quarters of monkey wrench between your devices and those that belong to others who are nearby. Overall, this is a basic type of security, designed to protect you and your devices.
Secondly, the lower competency used for short compass means a longer battery oomph. Most Bluetooth devices will arouse their gift from a battery, suggestion that element you amenability halt to never cease the battery enthusiasm is very same material.
The wireless networking offered by Bluetooth is in truth among the highest, identical though palpable uses short scale communication. Bluetooth is used shadow wireless controllers, the internet, and even wireless headsets.
For the best in short range technology, Bluetooth is extremely hard to beat. If you ‘ ve never tried Bluetooth before, now is the time. It ‘ s the best with wireless networking, especially for those who enjoy hands free talking on their cell phone.
Other wireless technology such as Garmin GPS utilizes complex wireless systems that let you know where you are, on any place in the world.
Multicast Wireless?
Multicasting is the process of broadcasting a huge number of routing packets to multiple destinations with the use of fewer networks. Multicasting when used over wireless networks like cellular telephones is known as multicast wireless.
As mobile companies all over the world upgrade their wireless networks to enhance the efficiency of new functions like mobile TV or IPTV,
the bandwidth usage goes up dramatically, leading to the need for multicast wireless technology.
Although the concept of wired multicasting, like ATM multicasting and IP multicasting, is still popular in some areas, it won’t be very long before wireless multicasting takes over the world.
Universal Mobile Telecommunication System (UMTS) is the preferred architecture that will promote third-generation mobile telecommunication systems.
UMTS is an offspring of the second-generation mobile telecommunication system (GSM). UMTS is geared to provide higher bandwidth radio access, especially for packet-data-based traffic, in addition to conventional voice services.
UMTS can provide maximum bandwidths ranging from 64kb/s – 2Mb/s. Enabling UMTS for different and concurrent high-bandwidth users, thereby reducing cost, will require multicast wireless protocols to be in place.
Multicast wireless technology replaces the older technology with only a few infrastructural changes.
To begin with, existing routers must be upgraded to include a specific multicast routing application in place of the older, traditional algorithms.
When we speak of wireless multicasting, the most important medium of communication or broadcasting is the omni-directional antennas.
Multicasting is generally conducted through what is known as source-based multicast trees. The multicast tree operates on a number of algorithmic structures.
The source-based mediums may need the receiver’s addresses and topology data. DVRMP and MOSPF are some of the best examples of the algorithms that are traditionally used in the process, especially for video broadcasting.
All wireless broadcasting or multicasting processes are guided by a bunch of multicasting network protocols.
Wireless multicasting technology has triggered a tremendous curiosity in the minds of technocrats across the world. As mentioned earlier,
the main reason for this is the rise in the number of mobile service provides, as well as the new functions and applications that are being integrated into mobile networks and wireless Internet connections.
Moreover, communication dysfunction is harmful for basic and necessary services like the military, so the introduction of multicast wireless has made staying connected both easier and more effective.
Cheaper broadcasting means many television channels can reach out to millions across the globe via IPTV and mobile TV broadcasting.
In retrospect, it is clear that the need for multicast wireless was always present, but the realization has set in a bit late.
The purpose of having a wireless multicasting procedure is to maximize the security levels that were often found lacking in wired multicasting.
Don’t be surprised if you see a constant growth in the quality of various broadcasting services now that they have wireless multicasting to fall back on.
Bluetooth – A Latest Achievement In Mobile Technology!
Bluetooth is a networking technology mainly invented to eliminate the usage of wires or cords for getting connectivity between two devices.
They do not need huge power supply which is considered as very ideal for battery-based devices like mobile phones. This new technology depends up on two things namely radio frequency technology and protocol software.
Bluetooth enabled devices has the stuff to transmit data between the other devices wirelessly.
Things to be considered at the time of transmitting data between two Bluetooth enabled devices:
• The amount of data to be sent
• The type of communication
• The radio frequency etc.
Why this wireless technology has been known by a strange name called “Bluetooth”?
Harald Bluetooth is the name of a Danish king who ruled Denmark during 1900s. In the memory of his name, this technology has named as “Bluetooth”.
IT was he who tried to consolidate Denmark and a part of Norway during his time. It has the ability to offer connection between devices like:
• Mobile phones
• Laptops
• Computers
• Printers
• Digital Cameras
• Video Game Consoles etc.
The main purpose of getting wireless connection between these devices is the transmission of data between compatible devices.
This technology has been operated with the support of radio waves with the frequency up to 2.4 GHz. It can support multi point instead of just point to point. You can make use of this technology in to a confined area from 10 to 15 meters apart.
This wireless technology can offer you data transmission speed up to 1 to 2 MB per second.
You can talk wirelessly with your headset or listen to your MP3s with a set of Bluetooth wireless stereo headphones and also, get your favourite pictures onto your PC for editing or send them straight to the printer without wire connections.
This technology is designed to have a very low power consumption. We can connect different devices across different platforms and can expect more speed especially in future.
Another advantage of Bluetooth is that it can automatically detect and communicate with other Bluetooth devices without any user input.
Bluetooth Applications
With Bluetooth being very popular with wireless, it’s no wonder there are many applications available for the technology. Below, you’ll find the applications for Bluetooth.
1. Wireless networking between laptops and desktop computers, or desktops that are in a confined space and little bandwidth is needed.
2. Peripherals such as mice, keyboards, and printers.
3. Cell phones with Bluetooth technology have been sold in large numbers, as they are able to connect to computers, PDAs (Personal Data Assistant), and various other devices. The standard also includes the
support for more powerful and longer range devices.
4. The transfer of files, images and MP3, between mobile phones.
5. Certain MP3 players and digital cameras to transfer files to and from computers.
6. Bluetooth technology headsets for smart phones and cell phones.
7. Data logging equipment that transmits data to a computer via Bluetooth technology.
8. Sony Playstation 3 and Nintendo Revolution will both use Bluetooth technology for their wireless controllers.
For Bluetooth, there are literally hundreds of different applications and devices available for you to use or purchase.
As you may already know, Bluetooth is the most popular wireless technology in the world. It’s very reliable, very dependable, and very hard to crack into.
There are many other applications for Bluetooth in development now, many of which plan to take the wireless age to the next level. Video game systems are using Bluetooth technology as well, for their wireless controllers. This is great news for gaming fans, as Bluetooth offers the best in wireless data transmission.
If your curious about applications for Bluetooth that are still in development, you can search on the internet. You can find all sorts of information, especially when it comes to Bluetooth. As the future arrives, you can expect Bluetooth to bring bigger and better things.
The Bluetooth Solution
The technology of Bluetooth will take small area networking to the next level by removing the need for user intervention and help keep transmission power very low to preserve battery power. Each transmission signal to and from your cellular phone will use just 1 mw of power, giving you plenty of space on your battery to talk.
Bluetooth is a networking standard that will work on two levels:
1. It will provide agreement at the physical level, as Bluetooth is a radio frequency standard.
2. It will provide agreement at the level of protocol, where products will have to agree on when bits are sent, how many are sent, and how the parties in conversation can be sure the message recieved is the same one that was sent.
The major draws to Bluetooth is the fact that it’s wireless, inexpensive, and automatic. There are other ways to get around wires, including infrared. Infrared uses light waves of a lower frequency than the human eye can, and is normally used in television remote controls.
The technology of Bluetooth is intended to get around the problems that normally come with
infrared systems.
The 1.0 older standard of Bluetooth has a max transfer speed of 1 MB a second, while the 2.0 Bluetooth standard can manage up to 3.0 MB a second.
To make things better, 2.0 is compatible with 1.0 devices. As a solution to wireless, Bluetooth will eliminate the need for messy cords, keeping everything nice and neat.
It’s perfect for those who like to talk on cell phones, as you no longer need to hold the phone next to your ear – which is great for those who travel a lot.

Creating a Wireless Desktop
We live in an age of technology and as such we are always looking for ways to make life easier or ways to make things look better.
In the home or office (or even the home office) making things look better involves getting rid of clutter. This is where the wireless desktop comes into play.
No wires means less clutter and because when using Bluetooth wireless devices line of sight is not needed, you can use your desk space to its optimum with no worries.
There is more to the wireless desktop than you might think as well. You will all be aware that you can get a wireless keyboard and mouse.
But wireless technology and Bluetooth in particular stretches much further than that. Your mobile phone if a recent one will probably have Bluetooth technology built into it. This means that you can easily connect it to your PC.
Companies such as Logitech offer software that really gets your mobile phone and your PC working together. Synchronization is just one aspect of this, but how about being able to type an SMS text message on your keyboard and send it without having to touch your phone.
This is all possible with the power of Bluetooth.
Communication with your mobile phone is not the only method of contact with Bluetooth. You can also get Bluetooth headsets that work with
Microsoft Messenger so you can add an easy chat functionality to your desktop. As new products come on the market Bluetooth becomes more and more popular. Peripheral devices such as Printers and Scanners can now be found.
The Wireless Keyboard and Mouse
This is the first device that you will probably buy for your wireless desktop. This is the basic starting point and probably the most effective.
The keyboard and mouse wires cannot be hidden away from sight as they have to be straight in front of you. plus limiting the mouse wire can mean limiting the mouse movement as well.
So A wireless keyboard and mouse will give you a better looking desktop as well as freedom to move your keyboard where you want it. You can have it on your lap or anywhere else in range.
Having a wireless mouse will also help in gaming. Most wireless mice are just as responsive as corded ones and your wire wont snag at that vital moment when online gaming.
Wireless Printers
While printers are not being produced as wireless as yet. The idea is very much being worked on. Currently what you can by for your
USB connected printers is a two small connecters that plug into your printer and USB port which connect together like a wireless network. Its almost a wireless USB connection if you like. I doubt that is how it will be described though.
The advantages of the wireless printer as well as the lack of wires behind your PC is the range can be increased as well as you being able to place your printer in a place where a USB cable would be unsuitable to travel.
A second advantage would be that connecting your printer to a wireless network for sharing will be much easier.
Wireless Networking
I think the biggest advantage of wireless technology has to be Wireless Networking. While Bluetooth technology is does not have the range in which to be affective at networking computers together. RF technology is still used however and is very easy to setup.
For a simple network (peer to peer) on two computers all you need is two wireless networking cards setup to the same channel. More complex networks can also be setup using a server and workstations. Anything you can do with a wired network you can do with wireless technology.
While we keep saying that the main advantage of wireless technology is that you don’t have wires lying around everywhere, this is more true than ever when we are talking about wireless networking.
When your computers are likely to be located in different room, the last thing you want is for wires to be laid around your home or office being an eyesore. Plus should you wish to move your computer at anytime, you don’t have to re-route the wires connecting your network together.
Security on Wireless networks is set by adding a name for your network which all computers on that network must be assigned to connect to, plus then you can add a password to keep unwanted intruders out from your files.
Software firewalls are also recommended on wireless connections (as well as wired) just for added security against unwanted virus’ or Adware/Spyware.
Wireless Headphones / Microphone
Wireless headphones are readily available from many manufacturers. These are really one of the most practical uses of wireless technology behind the networking.
Wireless headphones allow you to freely listen to your music, game or whatever noise your PC is making anywhere in your room without the restriction of wires.
Even if your wires are long enough they will still be a little dangerous stretched across the room. And we all know you like to dance around your room listening to your favourite tracks.
A set of wireless headphones could save you a few quid on broken items that your headphone wires have snagged on and brought crashing down to the floor :).
Wireless Speakers
Wireless speakers are poking out of the woodwork and those of you that have a 5.1 or above sound system will just how many wires are involved in that setup.
Not only do you have connection to the computer but each speaker is connected to the sub / power box and and you also have the volume control to deal with.
At time of writing this the US seem to have a decent supply of wireless speakers where as only a few can be found in the UK.
I am very sure that wireless speakers will become a lot more popular in the UK over the next couple of months.
Wireless speakers will remove loads of wires from the back of your computer. Using a 5.1 wireless system will allow you to place your speakers in the perfect position without any restrictions or ugly wires running along your walls or floor.
