  • What's better Wireless LAN or Bluetooth?

    Well, I'm considering establishing a wireless connection from my CarPC to the one I got at home. As I live in the 3d floor the main question for me is how far can I park my car to have access to the network.

    There are 2 main direction you could go:

    on the one hand WLan ($60 for 2 usb sticks) but you'll need an access point for the secure connection and it makes $70 more on the other hand you can buy 2 bluetooth dongles priced sth like $25 each. The newest one from theses toys can make about 330ft as far as I know.

    Does anybody have experience according to this topic? both bluetooth and WLan?

    for the range of bluetooth. 330ft is dead wrong, especialy with obstructions like walls.

      Bluetooth dongles with 2.4 freq can reach upto 100meters. Expansys.com has a good selection.

        Class 1 bluetooth devices have a theoretical maximum range of 100 meters, Line of Sight. If you're lucky, on a good day you'll get perhaps half of that reliably at any reasonable speed. If you have a couple walls and a car in the way, it will be reduced even further.

        802.11B/G is the way to go. The data rate is 12 times greater with 802.11B and 54 times greater with 802.11G.

        If you want to transfer several gigs of data , you have to use 802.11. Or let the transfer go for a few days.

        Get a USB 802.11 card and a wireless access point. It jacks into your home network and off you go. You're wasting your money on bluetooth for data transfer. Bluetooth has plenty of uses, but mass data transfer is not one of them.

          bluetooth would suck so bad for a wireless network. My phone drops connections to my laptop all the time and its only 2 feet away. Go with wifi its so damn cheap now

            Another thought. You mentioned security as a problem with 802.11.

            Having done research into WEP cracking. Anyone wanting to gain access to a wireless network with WEP encryption, would have to sit in your driveway for hours upon end capturing packets (a gig's worth or so) . The only time that a cracker could capture packets when you're sending information over the wireless network.

            I'm assuming you won't be using any other 802.11 devices other then the one in your car. This would mean someone would have to sit in your driveway for hours while you're sitting in your car, watching your data sync.

            I don't know about you, but I'd notice someone sitting in my driveway with a laptop for hours on end.

            If you STILL are worried about snoops, Use MAC address filtering. Then only the specific NIC cards you choose can access the network at all. Setting this up would take about 2 minutes.

              Ok guys, thank you for your answers. I'll look around for a good WLan device. What about usb dongles? Are they good enough to receive data from my home network?

                A usb device will probably be better then a PCI device. If it's USB, you can put it where you can get good signal, rather then having it attached to the back of your PC where it will get lots of EMI

                  I second the WiFi.

                  Why?

                  Coz that's what I use, I have a WAP indoors and a PCI wireless lan card in the PC, Have VNCserver set up on the car PC and then remotec ontrol it from indoors, to upgrade, update, or copy across MP3's.

                  currently speed is not greta but that's not surprising since the areiel is surronded by metal, but I will evetually mount the aeriel outside of the car.

                    I think most people have been using usb wireless LAN's, due to the nature of most people having Epia motherboards with limited pci slots. For data transfer to the car, I think usb is sufficient

                      I don't think so, but like fluffy said, you can put it anywhere you want to, to get a good signal. Plus, I'm sure that if you wanted to, you could remote-mount the aerial and extend a wire- it can't be that hard

                        I agree with the WiFi also. I'm using 802.11b at home and in the car. The access point is located in the center of my brick home. The carpc is useing a usb adapter. I'm also using a software package called Second Copy 2000. It transfers my mp3's to my car when ever it's in range. I have it set up to check the car files every 5 min, if it finds that the data on my car pc is not up to date with my home pc it will update the files automatically.

                          wifi is perfect for car use - you do not need an access point, you can run WEP on an ad-hoc ( 2 NIC's ) network, not only can I connect to computer a good 100meters away at 22mbit I can play LAN games with a friend a few roads away again at 22mbit - wireless rocks !!

                            I vote WiFi. I think that the best route is going USB, but I am not sure if there is a 802.11g USB one out yet. If so, go with it! I have a 802.11g PCI card, and it sucks becuase of the limits of the antenna. I am going to get an external antenna in the near future, so that clears that issue up. But if you use USB, you can easily use it on any computer which is nice. For range, perhaps 802.11a would be better because of the 5GHz bandwidth. I would use 'a' if I had a different AP (A/B/G).
