If a company has an Ethernet based LAN with 50 workstations and a server, And wish to add another 10 PCs to the network, Running additional cable to support this is not an option due to location and cost involved. What is the best wireless technology for that A B G or N and why? Thank you. Well, I have your answer right here. The answer depends on your location and the area for the new computers. I know that many will automatically say use N as it is the newest and the fastest of the wifi connections. That MAY be the correct technology to use in many cases. It will be the fastest of the ones available BUT it MAY NOT BE for your installation.. 802. 11a may be a good choice. Several think it is the oldest and slowest wifi, but that isn’t true. It is 5. 8 gig and does have a somewhat shorter range due to the frequencies used. BUT it also has the LEAST amount of interference. If you have an area with lots of wifi, then 802. 11a may well be the best choice if the area you need to cover is within a single building. The Pros of 802. 11a – fast maximum speed (full 54mbs); regulated frequencies prevent signal interference from other devices. Has reduced outside interference from all other wifi technology. Is a good choice for businesses in many cases. The Cons of 802. 11a – highest cost; shorter range signal that is more easily obstructed (can be overcome with multiple AP’s) A wireless survey of the area you want to use would be the way to really find out which one to use. If there isn’t too much other wifi in the area then N will be the faster of all these. On local networks that makes a big difference, for net access it doesn’t make much change between any of these. The Pros of 802. 11n – it has the fastest maximum speed and best signal range; it is more resistant to signal interference from outside sources but it is not immune. The Cons of 802. 11n – the standard is not yet finalized; costs more than 802. 11g; the use of multiple signals may greatly interfere with nearby 802. 11b/g based networks.

  1. “A” range is too short
    “B” is almost obsolete
    “G” is most common
    “N” offers highest speed

    I would go with 802. 11 n because it offers fastest speed for accessing files on the file server and other network resources.

  2. N – have a read of the full 9 yards – not only higher speed but better coverage with MIMO technology.

  3. Agreed that “N” is the best in your situation.

    If u get an “N” router it is compatible with “B” “G” and “N” network interface cards. So if some of your stations happened to have “G” cards the network would still function fine.

  4. 802. 11a is referring to a private, company-based networks. Often secure and not available to the public.

    802. 11b is about to bite the dust.

    802. 11g is the best and can cover 15 feet adequately from the wireless output point.

    And yes, 802. 11n is the dust that 802. 11b is about to bite.

  5. either N or G.
    G is slower but much much cheaper
    N is faster and you get far greater range than G, so if the computers are going to be a bigger distance from the router use N. The only problem with N is it can get expensive.
