High-speed dial-up works using radio waves to connect to the internet wirelessly. In the past, wired connections were faster but only allowed one device to connect at a time. The invention of wireless LANs allowed multiple devices to connect simultaneously for the first time. Early wireless LANs were much slower than wired connections due to limitations in radio wave strength and receiver sensitivity, but modern wireless LANs can achieve speeds equal to or greater than wired connections. This has made high-speed wireless internet access practical for business use.

2. High-speed technology
Any radio is full on this earth we are living.
Did you know that the radio is evolving? By
now, you can connect to the Internet at a
very high speed has become possible.

3. Communication technology
Because they were connected to the Internet
by cable, in the old days, the speed is fast.
Sometimes, however, if wired, and can not
connect to the net only one at a time, it's the
radio was invented.

4. Characteristics of Wireless LAN
The invention of the wireless LAN has been
unable to connect to the Internet at the same
time only about one block at a time until now,
we can now be connected at the same time at
the same time. Also, when wired, but it has
become a large number of cable anyway, I
have succeeded in that little.

5. previously Wireless LAN
Wireless LAN until now has succeeded in
reducing the cable wired than when indeed, is
the difference between wired and, what was
very slow communication speed. I think that is
a likely reason is that, as I think it did not match
the strength of the radio waves and radio
waves, the sensitivity of the device for it.

6. Current Wireless LAN
Unlike today's wireless LAN and wireless LAN
traditional, wired speed does not change with
time, I was able to connect to the Internet at a
speed or more. As a result, in the business
side, has become possible to work go
smoothly.
