What is bluetooth and how do I use it?
I got a new cell phone to replace my old out dated one. As a businessman I need to be able to stay on top of the latest technology. My new phone has bluetooth. What is it? What's it do?
Bluetooth is a device that lets you answer and talk on your cell phone in a hands free mode. It
attaches to your ear. You just push a button on the earpiece to answer the phone. It lets you answer your cell phone without actually having to hold the phone in your hand.
Can different wireless technology connect?
Can Ultra Wide Band Technology and Bluetooth sync together to transfer media files? Also can Zigbee be used for other purposes than monitoring energy consumption?
ZigBee has a variety of uses.
How is WiFi different to Bluetooth?
As title thanks. Ok they use different frequencies. What else? What's the big deal of making Bluetooth a separate ‘technology‘ from just conventional WiFi?
Bluetooth and WiFi® are both wireless technologies that use radio frequency (RF) waves to create networks, but they’re used for fundamentally different purposes. Bluetooth’s main purpose is to temporarily link an individual’s personal devices together over short distances, while WiFi’s purpose is to link multiple computers together over longer distances.
Although Bluetooth and WiFi both create networks, Bluetooth creates a Personal Area Network (PAN) by generating low frequency radio waves that all Bluetooth-enabled devices in the immediate area can join to be interoperable. You might think of this as a “shroud” surrounding an individual user. A Bluetooth headset, for example, allows hands-free cell phone use for driving or working. Other types of personal devices can swap files, synchronize data and even share access to the Internet through an Internet-enabled laptop, cell phone, personal digital assistant (PDA) or iPod®.
A Bluetooth network can also be used to send files from your laptop to your desktop, or from your laptop to your printer. If a machine does not come with Bluetooth capability built-in, adapters are available. Most adapters make use of a Universal Serial Bus (USB) port, but other types of adapters are also available.
WiFi also uses radio frequency (RF) waves, but its protocols are designed to connect multiple computers. In the case of a business, WiFi allows many computers to communicate with each other without stringing cable between them, saving considerable money and time in the installation process. Computers operating over the WiFi LAN can share databases, files, programs and resources including printers, scanners and fax machines. The computers might also share Internet access, though this isn’t a requirement of a LAN.
A home WiFi network is almost always setup to share Internet access among all computers in the household, while it may or may not be configured to share files and resources. Between Bluetooth and WiFi, Bluetooth is much easier to use for swapping files between computers at home, and even for sending files to a nearby printer. There is virtually no setup involved in establishing a Bluetooth network, while a LAN requires some configuration and know-how to allow sharing of files and resources.
Since Bluetooth works with battery operated devices, it most commonly uses a low-powered Class 2 radio to broadcast the RF network, generating a weak signal that doesn’t extend effectively beyond 30 feet (~10 meters) or so. Class 1 Bluetooth can reach 10x further, geared towards connecting home devices powered by electricity. WiFi also comes in different flavors and architectures, currently meeting or exceeding the 300-foot (~100m) range.
Bluetooth and WiFi each follow specific protocols and standards that make it easy for manufacturers to design and market Bluetooth and WiFi products that will be interoperable with other brands and products that support the same standards. For example, as of winter 2008 the current Bluetooth standard is 2.0 and the newest available WiFi standard is 802.11n, faster than the previous standard, 802.11g. When shopping for network-capable devices, be sure they support the desired standard and version.
Another way that Bluetooth and WiFi differ is that WiFi is supported by modems and routers, while a near-infinite range of products might support Bluetooth. Personal devices and home entertainment products are forever evolving, making interoperability a highly desired feature. Perhaps the biggest commonality between Bluetooth and WiFi is that both technologies are incredibly useful and widespread; in homes, businesses, government, and in virtually every aspect of life.
What's the bluetooth channel that using it fot searching,sent and recive ?
The bluetooth works on 2.4 GHz frequency that send and recieve through it .
heard of this Egyptian technology before?
no offense i am proud of my ancient Egyptian civilization :)

>So, not to be outdone, in the weeks that followed, American

>One week later, the

i have posted two Egyptian jokes of that type before .. check out my history and read them ;)
Hope you don't mind but I have copied and posted this one up at University in Australia
It will be a definite hit with all the Pro's,Lecturers and other students. I am sure it must have been originally written by someone experienced in researching Egypt's incredible history.
Another big thanks for brightening up our day!!
Apologies to the questioner
I am directing this at another answerer.
But what the ? Does, the theme of this joke have to do with taking surveys.
You are another one of these that uses the site just to flog their “enterprises”,that is not what this is about. GET IT!
Go away and flog your scams on surveys and polls or whatever, where ever!
