Sandra asks…

How cell phone connected should you stay when you're on vacation?

My boyfriend always has his cell phone and bluetooth on him, even on vacations. The phone isn't for business use. He constantly takes calls from his friends during vacation to discuss normal stuff like Halo 3 or who's the most underrated rookie in the NFL. I think it interrupts our vacation since he zones out when he receives calls and slows down our group.

Almost every vacation picture he's in has his bluetooth in it (I remembered to ask him to put it in his pocket for the other pics). I ask him to call his friends in the hotel when we have down time but he says stuff like “This is what technology is for. It's no big deal.”

Are the phone calls excessive for a vacation?

Is having your bluetooth (it's a big one!) in vacation pics tacky?

dknol answers:

Keep cell phones handy in case of an emergency, but don't use them for stuff that's not important. What's the point in taking a vacation if you're going to waste it on the phone? If he wanted to talk to his friends on the phone, he could've done that at home!

WiFi is wireless, Blue Tooth is for connecting any type of Blue Tooth devise to a laptop from a external Blue Tooth key board, head set to a smart phone etc.
Wi-Fi (also spelled Wifi or WiFi) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. Http://
Bluetooth, is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecom vendor Ericsson in 1994,[2] it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

How does bluetooth work with a mobile phone ?

I have quite an old mobile at the moment which does not have all of the fancy gadgets on it. I am hoping to change it for a more up to date model.

How does Bluetooth work?

In the world of Bluetooth wireless technology, there are no wires and virtually no limits. Bluetooth operates on a 2.4GHz band that’s available everywhere, so no license or subscription is necessary. Using adaptive frequency hopping (AFH), the signal “hops” to various frequencies to help ensure your signal is secure. Additionally, Bluetooth products use 128-bit encryption and a PIN code upon the first connection, giving you a secure connection every time.
Unlike other wireless technology, such as infrared, the devices you want to synchronize don’t have to be facing each other to make the connection. As long as two Bluetooth enabled devices are within a specified range of one another, the connection will be made. This means you can talk on a wireless headset with your mobile phone stashed in the other room, access data from your PC on your mobile phone, or wirelessly stream music from your iPod to your home stereo. The possibilities are truly endless!

Operating range for Bluetooth enabled devices depends on the class. Class 1 devices have a range of 100 meters (300 feet) and Class 2 devices have a range of 10 meters (30 feet). Class 2 devices are most commonly found in mobile devices.

George asks…

How can i share dial up connection using bluetooth?

How can i share dial up connection using bluetooth between two computer please tell me step wise in window 7 and window xp

dknol answers:

Bluetooth is not intended to be used for robust network sharing the way that you are trying to use it.

Do share a dial-up connection, you should use a TCP network technology like ethernet (either using a switch, or direct PC-to-laptop connection via crossover cable), or WiFi (using a wireless access point, or direct PC-to-laptop connection via ad-hoc connection).

Windows XP has a wizard that takes care of the sharing for you. Just right-click on the network connection you want to share, go to properties, go to Advanced, and check the “Share this ocnnection” checkbox. Your laptop should be configured for DHCP. Your laptop will find your desktop PC, and configure its settings to connect to the desktop PC and share the dial-up connection.

If you do these steps manually, you will need to bridge your two network connections (dial-up connection, plus whatever connection you are using to connect between laptop/PC), assign a static IP to both your desktop and laptop computers on the same subnet, and set the “Gateway” of your laptop's TCP settings to the IP address of your desktop.
