Wireless Help?

Question

Good day. In school, a wireless connection was installed recently but is restricted to students working or people generally working in the IT Department which is on level 2. I have the access number to use the wireless. I understand the wireless connection is only picked up on level 2 and once u past that area, it get weak and picks up nothing at all. One of my classrooms on level 3 is right above the wireless source. I wud like to kno if wireless can pass through concrete since it is a concrete floor. The wireless connection is 40-50MB per sec. If it does pass thru concrete, what wud in yur estimation the connection will be? and thanks! Laterz.

Answer 1

Yes, wireless connection can pass through concrete but you have to consider these:

1. the thicker the concrete, the weaker the signal.

2. It also depends on how high the ceiling of the 2nd floor to the 3rd floor. Same principle, the higher the distance, the weaker the signal.

3. If the radio signal of the wireless is strong you have a fair chance of getting it.

Remember, even if you have the pass code (WEP key), you might not be able to you it if they only allow the MAC address of a computer.

GOOD LUCK!

Answer 2

Speed is not affected directly. The signal strength is.
The signal strength is 1/r^2 (r squared, where r is distance.)
The concrete adds more distance "r", so the signal strength becomes weaker. The receiver on the computer can not establish "link" so it will try other channels (spread spectrum),
and tries to "lock in" to a channel with more power.
As the signal levels drop further, then it becomes ambient noise. The wireless connection on the PC will say no wireless networks found. The other logical step is to increase the level of the transmitter and hence reducing bit rate. I have seen bit rates as low as 1 MPS for 802.11g networks. The next thing you can do is add an wireless amplifier to strength the signal level. This method works really good. You will on a 802.11g 54MPS and very good to excellent signal strength will be presented.

Answer 3

I am sorry to have to tell you this but wireless signals do not pass through cement easily at all. It will interfere in connectivity to an extreme measure. Which is why many use concrete in their walls at offices when using wireless connections. It provides a barrier to the network.

Sorry to tell you but it just will not provide enough connectivity for you to have a good solid connection, if any connection at all. I hope you have a good day.

Answer 4

WiFi can pass through concrete but is generally greatly weakend by it. How fast your connection is going to depend on the signal strength. The only way to know is to try it.

Answer 5

if you have a good router on a 10 gb ethernet card for the router to link up to it will pass by anything you can be on the 25 floor of a hotel in nyc and use your laptop in the car on the street the wireless is not restricted

Answer 6

Hello,
I currently have a network running at your speed and i have setup many for family and friends and they all go through concreat walls. It does not really affect your connection speed although it may affect it a little bit but it depends on the qualitly of the wireless newtwork you are using.
