Wirelessness – what tha? dual band? 2.4 or 5GHz “n”?

Having been doing some shopping for a wireless network of late I thought I’d try and discover what the whole “dual band” ‘n’ router thing was and why I would benefit from buying one especially since the costs are much higher than a single band ‘n’ model. In the process I’ve learned a lot more about bandwidths and the pro’s and con’s of 2.4GHz versus a 5GHz band. I didn’t know the draft ‘n’ specification includes both radio frequency bands; furthermore, it doesn’t necessarily require operation on both. Yes, that means it could be either one and this is of course pretty important to connecting a transmitter with a receiver (networking). I’ve also learned that there aren’t many 5GHz ‘n’ products on the market if there are any at all.  Let me Google that for you.  I’ve also learned that the promise of a 5GHz HOV styled expressway for wirelessness is in reality less than fantastic in that the higher bandwidth 5GHz doesn’t penetrate through walls as well nor go quite as far as 2.4GHz.

Here’s some more 5GHz food for thought – http://blogs.zdnet.com/Ou/?p=411

The next ongoing discovery was that Linksys (and others aka NetGear do the same) sells and promotes their simultaneous “dual band” expensive high-margin router (WRT610n) promising the ability to get better HD video streaming and oimagenline gaming performance on the relatively empty 5GHz band versus the crowded 2.4GHz band. …that sounds great The hollow and empty promise truth is that Linksys doesn’t sell a single 5GHz N network adapter (WMP300N is 2.4GHz) except for notebooks; you aren’t going to be throwing a simple adapter into that gaming rig box at your or your boy’s desk. That’s right and you are probably now connecting the dots. …all hype and no delivery Worse yet, you cannot easily find what band their “N” adapter offerings operates at (whether 2.4GHz or 5GHz); at least not from any of the product literature, spec sheets, and packaging that I’ve looked over (some mfg’s do provide this). Lacking a desired decent desktop adapter card, your only option then is to purchase another 5 GHz router and use it as a bridge with its wired ports.  In fact this is kinda what NetGear is selling as a “kit”.

bah humbug!  …this is one frustrated & frequency fatigued shopper

  1. Ahh, This is the same question and frustration I have been trying to understand, thank you for your blog.

    I have even spoken to CISCO who was confused about whether thier dual band router would operate in 2.4 and 5 with my laptop inbuilt adapter, eventaully deciding that I would have to purchase one of theirs to get the best result.

    what a con these are, and I’m sure they will sell well as the promotions look great, I almost bought a dual band router, almost.

  2. Thanks , for blog ,,,,, instresting to note ,,,,,
    That I am from Australia , yes the LAND DOWN UNDER ,,,, and if you ever bought one of these products:
    MS Office , Windows , Netgear Routers , Linksys Routers ,,, etc etc ,,, you would have seen this “weird orange/reddish” page inserted into the PRODUCT PACKING /Boxes in the above mentioned products…….

    Ok ok what it THAT PAGE ABOUT ::::

    its called the LEMON LAW paper!! ie , if any products claims and or workings DONT WORK LIKE the description or SPECIFINATIONS CLAIM it to be , then you GET YOUR MONEY BACK…. yes you get your money back and you get to keep the product, free ( if u wish)

    so am wondering when the REAL LEMON LAW that USA/ Canada claims to have will be enforced ,,,,, am sure most of you’s would get the point here ,,, right ? !!!!

    and to digress for a bit !!!

    As a added example ::: 720/p resolution LCD/Plasama tv !!! Only USA has such things , and yet its still called ” HIGH DEFINATION TV !! > I am still amazed that the LAND OF OBAMA(my hero) still selling these things ‘under HIGH DEFINATION TV !!
    note my CRT screen on my desk that I bought in 1992 was doing 720p resultion , that still sits there showing me my CAD drawings very very well , even today , and I never paid those ‘usa high def prices’ even back in 1992 ~~~

    so good luck and best wishes for JUNE launch date for REAL HIGH DEF….

    Giday matey !
