Frequently Asked Questions

Can weather / lightning affect the Wireless Internet signal?
Your speed may decrease by up to 50% during torrential downpours of 6" per hour or more. Luckily, this type of rain is very rare in our coverage areas, happening fewer than 3 to 4 times per winter. Wireless links are not affected by fog, smog, or non-torrential rain. However lightning can and does affect wireless signal- including cell phone signals. Lightning strikes kill all transmissions within the strike vicinity. The transmissions resume immediately however and will re-transmit the lost data if possible. If not the session will re-instate and you will have to resend the data.


What can affect the Wireless Internet signal?
Our signal will penetrate the walls of most buildings. It will not pass through live trees. The general rule of thumb is that the radio signal will pass through anything that doesn't contain water.


How does the weather affect WebPerception's Internet Service?
The effects of weather on wireless radio signals vary based on the frequency (2.4ghz, 5ghz, etc.) used and the distance the signal travels. With the frequencies and distances in our network, signal degradation due to rain, snow, or fog are negligible. However there are 3 or 4 times each winter when the skies open and it pours that you will see, if you're actually at your computer, a slowdown. Since downpours never last long neither will the slowdown.


Can other equipment interfere with a wireless Internet signal?
There are known issues with interference, including (but not limited to) amateur radios, baby monitors, other microwave towers or antennas, garage door openers, and other 2.4 or 5ghz wireless devices. If you have a 2.4ghz cordless phone you will need to keep any phone or base station at least 10 feet away from your WiFi router.


Are there any health or safety concerns with the wireless signal?
The technology used by WebPerception operates at very low power levels, less than a cell phone, and much less than the amount that is emitted by your microwave oven. Also, radio frequency power drops dramatically as you move away from the power source. Typically, our antenna would not be placed where any person would be able to stand right in front of it for any significant period of time.


Do trees and buildings interfere with a wireless internet signal?
Yes, both can diminish the signal strength. For that reason you will need a clear line-of-sight to one of our tower or repeater sites. Large amounts of rain diminish the signal, but wet weather also evens the air temperature. This reduces problems with interference issues such as fade drift, thereby increasing your speeds. At most you may see a 10% reduction in speed during a heavy rain storm.


Why does the wireless WiFi signal in my home keep disconnecting?
Performance of any wireless device can be affected by interference from other devices like baby monitors, cordless phones, microwave oven, and your neighbor's WiFi networks. Please change your wireless channel to 1 or 11 to see if the signal strength improves. (Keep reading below.)


How can I increase signal on my wireless connection?
You may want to consider changing your router to channel 1 or 11. Channel 6 is the most commonly used channel for 2.4ghz devices (including cordless phones, wireless keyboards and mice). In most cases you will get the maximum range on channel 1. Make sure that the router in question is positioned in the highest point available. For example, if the building is two stories high, you need to place the router on the second floor - not the first floor. You should never place the WiFi device on the floor under your desk or TV... (Keep reading below.)


What is the coverage area of a WiFi signal within the home?
The wireless signal of a standard Wireless Access Point (WAP) will cover a radius of 150 feet in the home or office environment but you must deduct 50 feet for every wall the signal passes through. Beyond 150 feet wireless signal strength will become weaker and data rates will drop. Actual performance may vary depending on the conditions at the location where the Access Points are installed. There are newer Long Range Access Points (LR APs) that can cover 300 feet but you still need to deduct 50 feet per wall. You may need more than one LR AP to get the best coverage.
Here are the signal losses from typical homes and offices in dB:

Human body 3
Cubicles 3 to 5
Window, Brick Wall 2
Brick Wall next to a Metal Door 3
Glass Window (non tinted) 2
Clear Glass Window 2
Office window 3
Plasterboard wall 3
Marble 5
Glass wall with metal frame 6
Metal Frame Glass Wall Into Building 6
Metal Frame Clear Glass Wall 6
Metal Screened Clear Glass Window 6
Wired-Glass Window 8
Cinder block wall 4
Dry Wall 4
Cinder Block Wall 4
Sheetrock/Wood Frame Wall 5
Sheetrock/Metal Framed Wall 6
Office Wall 6
Brick Wall 2 to 8
Concrete Wall 10 to 15
Wooden Door 3
Metal door 6
Metal Door in Office Wall 6
Metal door in brick wall 12 to 13
Note that each time the WiFi signal goes through one of the above you must deduct the loss. A typical WiFi Access Point (WAP) transmits 20dB so as the signal passes through the above in your home or office deduct the loss and soon you will see why you may need more than one WAP. The above can also help with WAP placement in your home or office.

What is wireless Internet?
Wireless Internet is exactly what it sounds like. WebPerception connects you to the Internet via a high-speed wireless radio. Data is encapsulated and sent over a radio frequency to the next radio where the data is unencapsulated and sent further on its way. Unknown to most people is that every day almost all of the data sent across America and the world travels some of the way wirelessly! Data sent over a 35 mile link on WebPerception's network will travel that distance, round trip, in less than 1 millisecond (one thousandth of a second).
