There are several types of Wireless networks. However,
they can be broken down into very specific needs to help you determine
what you are looking for in your wireless system.
If you have several computers inside of an office
and you wish to connect them wirelessly, it is very simple. Each
computer, whether it is a desktop or notebook will need a wireless
You will need an access point on your primary internet
connection or router. You will need a wireless card for your other
Wireless Card for Desktop computers.
- WaveRVII for notebook computers. or the Notebook Wireless Kits
bridge for servers or Ethernet type computers.
Desktop computers will require a PCI Wireless Card
that inserts into the back or your computer or even our custom solutions.
Notebook computers require either a built-in wireless
card (which comes standard in most notebooks now), or you can get
a much longer
range WiFi card and antenna from RadioLabs. Another popular solution is the WaveRVII, high power 200mW output notebook system.
We offer 2 different kits, long range B and long range
b/g/super g. If you are linking buildings, see the Wireless
Bridge system we offer.
Here is the real difference and may make up your mind
as to what you need. You do not need 802.11G, Super G or anything
else if you just want a simple, high speed internet connection.
802.11B cards operate on a very well known, very stable,
proven industry standard. The speed is 11MBPS. This is lightning
fast, especially when you consider that the fastest cable modem
has a download rate of 1.5 MBPS, 7.3 times slower than the 802.11
speed. In fact, a T1 line operates at even a slower speed.
You know that little icon that shows up and says you
are connected at 54MBPS? Well, it’s definitely not telling
the truth! In fact, you can be connected at a billion MBPS on some
alien technology card, yet you are never, ever, ever going to connect
to the internet at any speed higher than the internet connection…
I don’t care who you are. If you are using a 54 MBPS card
and connected to a Cable modem and you are surfing the web... you
are surfing the web at ONLY 1MBPS +/- .5 MBPS depending on your
carrier. DSL is worse, but I'm not going to get into that.
Sure, tell me you are connected to wireless, your
little window on your computer pops up and says you are connected
at 54MBPS and you are running DSL.. great, I’ll rip you up
with a 2MBPS connection, a “B” speed card with a Cable
The speed indicator is the biggest misconception in
wireless… It is a total marketing scam and should be outlawed
nationwide. I know I am going to draw a ton of heat for this, but
this has absolutely got to stop!!! The Mimo stuff, sure, it’s
fast if you are transferring a huge file on a closed network system,
guaranteed.. I love it for that reason. But, the speed, technology
and the A/B/G/N standards are just totally crazy!
Here’s an example of what can happen with your
network if you have no clue what’s happening:
802.11B – The first standard
adopted.. and the best!!! 11MBPS, Ultra stable with the correct
stable equipment will smoke anything on the market. “Tortoise
and the Hair” type thing. It lopes along and is totally stable.
My #1 choice and the only standard you will find at hotels, wifi
hotspots, Internet service providers stable wireless links and almost
anything you find out there in the community. It’s ‘da
Bomb and it’s what you should use if you are not transferring
massive files, at close range, in your office. 802.11B is the stuff
to use and will be for a very long time! (as a side note, I didn’t
like the fact that slower was better either, but it’s pretty
awesome!) For the best 802.11B
Notebook kit, please check out our notebook
wifi kit. You won't be upset if you purchase it.
802.11G – This is the current
standard for high speed wireless connect and what the market is
touting. It is really good if you are trying to use it for transferring
big files from a notebook or office computers, where someone doesn’t
want to run a CAT-5 cable. It will lope along at about 1/5th the
speed of a directly connected Ethernet cable and get your files
transferred. However, if you have interference, no external antenna
or you are trying to back up your hard drive at the same time as
someone else on the network.. give up!! Make some coffee, move your
computer closer and have a good night! I love the technology, but
I hate the stupid understanding in the community that G is better
than B, because it’s just not true unless you are sitting
next to your computer. See my Latency explanation below. Our new
WaveRVII WiFi High power card will give you 802.11B and G at the

like cordless phones. Cool stuff, developed a very long time ago
by a famous actress Hedy Lamar during WWII. Yes, this technology
was designed for weapons, specifically torpedoes. The technology
was invented to eliminate signal jamming. It breaks the signal up
and spreads the signal throughout a certain signal range. So, if
it was developed for Jamming, it will probably help eliminate interference
in your wireless system. Go figure!
802.11G = OFDM = Orthogonal Frequency
Division Multiplexing. Wow, huge word! What in God’s name
does that mean? Without getting all Geek on you, that’s a
more advanced, yet more interference prone form of communication
for digital data transfer. More data sent through the air requires
more complex ways of sending data. OFDM breaks the signal down into
little chunks, transmits separate parts of the data out over separate
frequencies and then, god forbid someone turn on a microwave oven
in the next room and scatter your data all over the place. However,
a High Quality card is “Smart” and can take that interference
and change frequencies and channels. RadioLabs only sells “G”
type cards which have this capability. If you go to some major retailer
and find a wireless USB adapter that will do “G” speed
and you are only getting 1 MBPS and ultra-low speed connect, don’t
call us until you toss it in the garbage!
802.11A = Same thing as the “G”
standard, but it’s currently done at 5.8 GHz and the band
is much less cluttered. Really cool stuff and it works. If you are
doing direct shots, contact us for your solution.
802.11N = Mimo… This technology
uses multiple antennas to basically steer the antenna, route the
packets to an individual client, increases the speed and is backwards
compatible to all of the older standards. However, “N”
is meant to be used at close range at increased speeds. I am sure
the technology is going to do well, but I am still skeptical. I
will take the old “B” speed now, with a good antenna
and make long range connections.
There is one last thing I have to explain in this
article, for everyone looking for wireless range. LATENCY!
No matter if it is a radio signal, a laser, the light
coming off of the Sun or a Charged particle Ray shooting through
space… nothing goes faster than the speed of light!
You can have your ULTRA high gigabyte, super –
ultra speed million dollar network system, with the latest technology
and whatever. Hell, you could invest 1 billion dollars into a wireless
bridge for a 10 mile link. With the current technology.. good luck!
You run into a problem “The Speed of Light”. Good luck
on that one buddy… If I could figure out a way to speed up
light faster, I definitely wouldn’t be writing this article
or working with wireless. You cannot and will not get your single
radio network to go faster than 11MBPS at more than 20 miles, especially
considering path-loss. This is a completely different matter and
we will deal with this in a separate article. You can increase your
packet size, but if you have a problem in the packet it will take
a while to correct.
The speed of light is really really fast! It travels
at 186,200 Miles per second. But now technology has advanced to
the point that it’s pretty slow now. Ok, figure you are sending
56 million bits (little on and off signals), through the air at
the speed of light. Great.. congratulations! You’ve just now
violated the speed of light. Those bits can’t travel that
fast when you get out 5-10 miles. The bits are now having errors
and colliding with each other when the radios talk back and forth.
With only using a single wireless access point or router, this problem
won’t be solved as long as I am alive.
