Your Questions About Bluetooth Technology Uses

James asks…

What are some nice old cars (so to speak ) that have good technology and look nice ?

I know the 2007 Nissan Altima has a smart key and Bluetooth and looks nice. What are some other kinds of car no matter the make or year ? Also some that wouldn't cost much used. Yes I'm looking to buy a used car if your wondering. Thank you.

How do I connect to the Internet on my Compaq nw8240 mobile workstation?

Ive just installed a fresh copy of Windows Vista ultimate, and I cant figure out how to connect to the internet. It has a bluetooth device installed listed under Network Devices in the device manager. Do i have to use the bluetooth device to connect to the internet? If so, how do I do that?

Can a normal wireless mouse work on bluetooth?

I was wondering whether if a normal wireless mouse work on the bluetooth network on my computer, i was wondering this because wireless mice work on 2.4ghz and the bluetooth frequency also runs on 2.4ghz frequency and so maybe i could buy a wireless mouse without having to give up a USB drive for the stupid receiver. it would also save me quite a bit of money :P

any answers apreciated

dknol answers:

Sorry topu. Though the frequencies may be the same the data protocol aren't.
Neither is the bandwidth.

here's an answer from concerning the pros and cons of RF and Bluetooth:
Well, first of all, bluetooth *is* rf. So, you really mean bluetooth vs. Non-bluetooth.

There are various non-bluetooth technologies available.

Bluetooth uses frequency-hopping in the 2400 mHz band. It was designed to use relatively little power and be reasonably resistant to interference. One advantage is that it is the only rf technology currently used for wireless mice and keyboards that is standardized across manufacturers.

A disadvantage of any 2400 mHz device is that they are competing with a wide variety of devices – wireless phone, WiFi, and your microwave oven.

Most traditional wireless mice and keyboards do not frequency-hop and use a single channel for the keyboard and one for the mouse. (Some older equipment may come with a single-channel transceiver, which can talk only to a mouse or keyboard. These are 27mHz. They compete with Citizens Band radio and some other low-power unlicensed devices. (Letsee, remote control for model planes, etc. Would be one.) I've used Logitech wireless mice and keyboards for years, and never had a problem with battery life. However, some newer fancy models can run down batteries quickly. They are not interchangable between brands. Ironically, despite lacking frequency-hopping, these seem to be amoung the least affected by interference, because the Citizens Band has fallen into disuse.

On batteries – if the device has high consumption, use rechargables. If the device has low consumption, use regular alkalines. The problem with rechargables in low-consumption devices is that rechargables have a short shelf-life. Alkalines will last longer. Some devices give you no choice, and have proprietary rechargables. They do that because they are high consumption.

Some mice now use 2400 mHz, frequency hopping, but use proprietary standards – not bluetooth, and not WiFi. There is some interchangability within the same manufacturer. For example, Logitech has compatible desktop mouse, notebook mouse, and presentation pointer. You have to look carefully at the packaging for the 2400 mHz designation. I have the Logitech MX610 left-handed mouse, which is 2400 mHz. I got it only because it's the only left-handed mouse available. It's fairly susceptable to interference, despite frequency-hopping. I can't use it when I am running the microwave oven in the next room. The battery life is very good, though I have read complaints from others.

There also are IRDA (infrared) keyboards, and these are interchangable. Not sure if there are IRDA mice.

I actually went back to a wired keyboard, as I wanted to try a Model M (not a real IBM, but the currently-manufactured licensed product from Unicomp) which I really like. It's the mouse where you really need wireless. I always found the cord to get in the way.

Frequency-hopping and mice/keyboards does not necessarily mix well. Frequency-hopping depends on the fact that if there is interference on one frequency, there won't be on another. The device randomly hops around to different channels. The problem is, if there IS interference, then there has to be a re-transmission. Works well for streams of data that can be buffered (audio, video) and OK web browsing, etc. Problem with mice/keyboards is that users expect real-time response – you don't expect to hit a key or move the mouse and sometimes have a delay.

Hope I've helped.

Good luck and safe computing!

Daniel asks…

What is a good iphone 4 accessory for someone who is not technologically inclined?

I never used an iphone. Out of principal i stay away from the things; but i'm purchasing a gift, and need to expertise with the iphone market.

The receiver isn't really familar with technology. So something that will help their use of the iphone.
bluetooth headsets, large battery pack, leather cases are pretty much out of the question.
What other suggestions do you have?

dknol answers:

How about an iTunes gift card, so that they can download some music or apps.

Or if you're on a lower budget, maybe a Bumper or Dock from Apple (other cheaper ones are also available).

Or if your budget is lower still, a screen protector?

Hope this helps
