Wireless Protocols: Which to choose

Posted on 2004-11-16
Last Modified: 2013-11-09
Could someone sum the pro's and con's of the wireless versions (a,b,g,etc...). I am switching to wireless at my house. There will be both mac and pc's on the lan. Is one of the protocols the emerging standard? Are any of the others becoming obsolete? What would you recommend.

Thanks for your time.

    That is a good place to describe the differences in the technology.  Personally, I would recommend getting 802.11g equipment as it is both backwards compatible with 802.11b hardware and it's just as fast as 802.11a.

    Thanks, please answer my two questions above.

    Also concerning that link, what does it mean by Capacity: 3 channels?

    b is slower than a and g.
    a is better than g as the signal of g easily affect by other quipment

    but the use of a is restricted internally

    802.11g Ethernet is the latest technology out on the market today.  As said above it is compatible with B and sometimes with A.  Check the equipment specs.

    Here are some useful sites on the subject.

    The main one:
    802.11b vs. 802.11g, or Wireless What Should I Get?  -----> not sure this will direct you to it, but this was the link.  If not, just look for thee title at the beginning of this line on the site.

    When they say G is compatible with B, do they mean you can have 2 users, one with a B card and one with a G card both running through a G router?

    Accepted Solution

    Ok. 802.11G uses the same frequency as 802.11B so if you have an 802.11G access point (usually integrated w/ your router) then either type of client can use the access point. Further an 802.11G client card can access either type of access point.

    Ultimately you have no existing investment so compatibility is moot, go with what works best for you and use that solution throughout.

    now the difference between 802.11A and B : B has WAY more range than A but A has WAY more speed than B.
    802.11G is a "best of both worlds" solution that has the range of B and the speed of A. 802.11G effectively renders 802.11B obsolete.

    The big concern is that both 802.11B and G use a very common frequency (everything from your microwave to your flourescent lights bleed over) whereas 802.11A uses a less common frequency and thus CAN be usefull for areas where 802.11G doesn't work well due to interferance.

    OVERALL recommendation: 802.11G. it has the range of B and the speed of A. the frequency congestion isn't enough of a negative to counter that positive.

    Mac vs. PC doesn't matter. an access card is an access card. Mac brand air pods, air ports or whatever their marketing them as will be able to access an access point that is also accessed by a PC. effectively it's the same as a network card
