Wireless LANs - What is Wireless Lan?
Wireless LANs - What is Wireless Lan?
Wireless LANs and wired LANs operate in much the same way at the physical
level. That is, they both use electrical energy to transmit data. One encodes its
data upon an electrical impulse in a wire, and the other encodes it upon a radio
or light wave.
With a waveform, the amount of data which can be transmitted is theoretically,
directly proportional to the frequency of the wave. For example, if a particular
piece of switching equipment in a transmitter is capable of encoding
(modulating) one bit of data per cycle, then a wavelength with a frequency of 10
kHz (ten thousand cycles per second) is going to carry ten times as much data
as a wavelength having a frequency of 1 kHz in the same period of time. This
holds true for as long as the switching equipment can match the frequency.
Some modulating methods make it possible to encode up to 4 bits on a single
cycle. Considering this and the high frequencies available, wireless LANs have
the potential to transmit data at very high speeds.
You can know more about Wirelesslan in some sites like this one.
As already mentioned, the characteristics of a wave change with respect to the
rate of frequency change. The higher the frequency, the more the wave takes on
the properties of light and the more it is absorbed or reflected. This has a
number of implications; the main one being the fact that as the frequency
increases the range of the LAN decreases due to the greater attenuation of the
signal. Also, the equipment used to transmit and receive radio waves begins to
strike some physical limitations as the frequency increases, so there is an upper
limit to its practical application.
There is a wide frequency range which could potentially be used for wireless
LAN communication. The range from about 200 kHz, through the microwave
range, all the way up to the top of the infrared range at around 200 THz could be
utilized. When selecting a range upon which to build equipment, consideration
must be given to the required throughput versus transmission range. As one
increases, the other decreases as mentioned previously. Greater range can be
achieved at any frequency by increasing the transmission power. However,
most governments impose strict controls on power output through their licensing
and regulatory authorities. A more efficient antenna or a directional one can
increase the range of any transmission, but this is nowhere near as significant a
gain as simply increasing the power.

Will this switch work for a home office and lan party situation?
ES 1024 24 PORT UNMANAGED SWITCH.
I want to have 24 ports for internet and lan. Can I just plug this in and go... If the difficulty of use is minimal, I would still by it, but I need advice before I buy.
the IT guy at our tech college said to get a switch... what is the difference between hub and switch?
Yep, it will do fine. Plug and play, no setup needed. Your IT guy is absolutely correct!
I'm somewhat stunned that so many people have got this wrong! A switch is ALWAYS preferable to a hub! And there's no need for a relatively expensive 3Com unit with a gigabit uplink in the scenario you describe.
The difference between a switch and hub can best be explained with an analogy. A switch is like using the phone in your office to call someone in the office down the hall. The communication is private. A hub is like yelling at him down the hall. Everyone hears it.
A hub copies all packets received to all ports whereas a switch only copies them to the port where the destination host is connected. Hosts connected to a hub can only transmit and receive sequentially. Hosts connected to a switch can transmit and receive at the same time. A switch is therefore much more efficient. A switched network can carry much more traffic than a network using hubs.
