Your Questions About Bluetooth Technology Uses

Ken asks…

How does the Xbox 360 wireless controller connect to the Xbox?

I was wondering what technology it uses. I know it isn't bluetooth, but I have a wireless mouse and I was wondering if I could connect the controller to the mouse's adapter, rather than purchasing a Microsoft adapter for it…
I recently discovered that the wireless headset uses 2.4 GHz radio technology, and it said it uses the same stuff from the Xbox Controller, so i guess that's it!

dknol answers:

You are wrong about the fact. It indeed is bluetooth. It uses bluetooth technology to connect the wireless controllers.

How would a dog whistle affect bluetooth performance?

Ok, may sound silly but as I know bluetooth uses sound waves, right? I imagine at the high frequency range … (short distance, intensity of signal). A dog whistle uses similar? frequences…
Could I change the interaction between two bluetooth connected devices using a dog whistle (or a similar device with a high frequency output) ?

dknol answers:

You are mistaken. Bluetooth uses radio waves.

Bluetooth is the name for a short-range radio frequency (RF) technology that operates at 2.4 GHz and is capable of transmitting voice and data. The effective range of Bluetooth devices is 32 feet (10 meters). Bluetooth transfers data at the rate of 1 Mbps, which is from three to eight times the average speed of parallel and serial ports, respectively.

How much battery life does using the internet browser on an Env3 use up? What are some battery saving tips?

I like to use twitter & facebook on it. How fast will it drain my battery? anyways to save battery other than keeping it on low brightness?

dknol answers:

Not sure about the battery life on internet. I grabbed this from a yahoo article…..

Dim It

The brighter your screen, the more juice you're using. If you're in a dimly lit room, turn down your screen's brightness.If you use your smartphone to play music, lower the volume.

Stop Searching

It is great that you can use Bluetooth technology to connect your smartphone to a headset, or use Wi–Fi to speed up the downloading of e–mail messages. But when you're not using that headset or not near a Wi–Fi hot spot, turn off those features on the phone.

Skip a Generation

Your smartphone is also continually looking for a cellphone signal. If you're in a weak signal area, your phone must work even harder to find one, decreasing battery life. If you know that there is no coverage in your area, turn off your portable device's mobile capabilities

Check Mail Manually

Mobile smartphones can check for e–mail messages and instant messages automatically. Or they can be set to “push” notifications as soon as they arrive in your server's mailbox.

Both strategies can be power hogs. To increase your battery life, turn off push and increase the interval between when the phone checks for new messages. Or better, set up your phone to check for messages manually.

Jenny asks…

What is the difference between WiFi and bluetooth?

Does either (or both) use RF, or are the Infrared (or something totally different.) I am aware already that each is a corporate logo and is not necessarily descriptive of what it actually is.

dknol answers:

RF and network speed….

Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 frequencies. Bluetooth is limited to about 35 feet and 2-3Mbps….

Wi-Fi uses both single carrier direct-sequence spread spectrum radio technology (part of the larger family of spread spectrum systems) and multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology. The regulations for unlicensed spread spectrum enabled the development of Wi-Fi, its onetime competitor HomeRF, Bluetooth, and many other products such as some types of cordless telephones. Roughly 2.4Ghz regarding the frequency.

WiFi Speeds are significantly higher- a good theoretical maximum with current technology is about 320 Mb/s… Good luck actually achieving that, but it is theoretical, right?

How to access internet from a bluetooth enabled laptop to Samsung Corby mobile?

Hi all,

Please let me know the steps to access internet from a bluetooth enabled laptop to my samsung Corby via bluetooth.

Thanks in Advance

dknol answers:

Sorry to say but one cannot network using a bluetooth connnection. This is probably because bluetooth 2.0 (the one corby uses) is still not that fast enough to transfer small data packets rapidly (it was primarily designed to transfer medium sized continous files, not very tiny discontinous data packets), another problem is that today's windows computer still run on the services and technology of the earstwhile msdos which cannot acesses a bluetooth connection as a linking connection, windows fools the dos to think that the bluetooth device is connected to the computer through serial port, & thus you can transfer small amount of data.

Data packets are those very small files which make your computer or phone the part of the internet.

Simply speaking, Bluetooth was made to send small files between devices and not for networking, try using the data cable provided.

Thanks for going through my boring tech rubbish.
