Frequently Asked Questions

Can the signal penetrate walls and buildings?

FAQs | Xwire
Yes, the signal can pass through walls and buildings, depending on what the wall is made of or what is in the wall. Walls with sheet metal covering may reflect the signals, so the radio waves will not penetrate it. Also walls with lots of wiring and poor wiring insulation may cause interference and degradation of signal, and hence, poor performance.

Will the signal travel through walls?

Purdue University Calumet | CTIS - Wireless
Yes. CalNet uses radio waves, which can pass through glass and standard walls. It can also travel around corners, so you can still receive a signal on the other side of a more solid barrier (metal and cement are harder for the 2.4GHz signal to penetrate). No. Bluetooth is a 1Mbps (Megabits per second) standard for connecting small devices in close proximity, like connecting a palmtop computer to a cell phone. CalNet uses IEEE 802.

Do buildings interfere with the GPS signal?

Auto Nav 2000 Plus, Inc. - FAQ
GPS requires "line-of-sight" to receive signals from the satellites. Tall buildings, other large objects such as tress or covers even overpasses can cause interference with GPS receptions. Re-acquisition will occur once the obstacle has been cleared, only takes a matter of second, which, again, is why most of the vehicle navigation systems have more then one method for navigation purposes such as Dead Reckoning features.

Will the signal go through trees and buildings?

KWISP Frequenty Asked Questions
In most cases you will need a clear line of sight to the tower. Microwaves at frequencies of 2.4 and 5.8 GHz do not travel well through foliage and solid objects. We do have 900 MHz NLOS (non line of sight) equpment in selected areas with a lot of trees.

Will the inert gas effect penetrate through walls? What stops the effect?

Inert Gases FAQ
Yes, the effect penetrates through walls. The 70% or so of the people who can consistently feel the effect report being able to sense it passing through all materials, with one exception: lead. A thick (1/4" or more) sheet of lead seems to stop the "beam" from the device.

How far can sunlight penetrate into the ocean?

Oceans FAQ
Significant sunlight can only penetrate 100 meters freely. Because seawater is relatively transparent, about 5% of sunlight penetrates to a depth of 262 feet (80 meters). However, if the water contains significant amounts of silt, algae or other factors, the penetration depth can be reduced to 164 feet (50 meters) or less. Learn more about the ocean light zone.

Can my wireless signal pass through floors, walls, and glass?

Actiontec
The surrounding physical environment can have varying effects on signal strength and quality. The denser an object (a concrete wall compared to a plaster wall, for example), the greater the interference will be. Concrete or metal-reinforced structures cause a higher degree of wireless signal loss than those made of wood, plaster, or glass.

What is the penetration ability of the signal through walls/ceilings/objects?

BigSecurity.com | Support
Our standard 700 feet LOS (line of site) system can typically penetrate 6-8 interior walls with ranges up to 400 feet and is designed to work comfortably in a 5500 square foot home or office. The signal penetrates most solid objects, including glass, plastic, wood, fiberglass and some metals. The denser a material, the more the signal is weakened.

Do trees and buildings interfere with a wireless Internet signal?

Execulink Telecom - Support Centre - Internet FAQ's
Yes, both will diminish the signal. For that reason you will need a clear line-of-sight to one of our access points. Yes and no. Large amounts of rain or snow may 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 or snow storm.

Gameplay - Hardwar FAQ
Certain key buildings can be targeted from the local services menu. You can select target from messages. Alternatively, fly close to the building, targeting it, and lock the target for future reference. For new pilots, finding anything in the fog of Titan is difficult, particularly in the larger craters such as Downtown. Try to remember how a few important buildings relate to different tunnel mouths. You may find it useful to refer to maps of Titan, which can be found here: http://www.capsu.

edit] Why do I get bad signal / traces in city centers / near big metal buildings?

FAQ - OpenStreetMap
For a GPS to work and achieve some accuracy it needs to receive at least three satellite signals. Often when in city centers there are many tall buildings that can block these signals and stop the GPS from being able to work out where it is. There may also be multi-path effects from the material making up the buildings around you, whereby signals bounce off them so the receiver actually thinks it is somewhere in the buildings around.

What do the signal names 'signal 0', 'signal 1', ... mean?

Frequently Asked Questions about PhysioNet
noted in the answers to the previous two questions, signal names recorded in header files describe the signals in each record. In rare cases, however, this information is missing, usually because it was not preserved when the signals were recorded. Names of the form 'signal N' are default signal names used in such cases; they may appear in header files explicitly, or they may be displayed by PhysioToolkit software if no explicit signal names appear in a header file.

What is a signal?

FAQ
Technical indicators generate various types of signals based on such events as the crossing of two lines, a line crossing an important threshold, or a particular pattern such as divergence between the price and the indicator. These events may provide an early warning of a price move and often provide investors with specific buy and sell signals.

How does it penetrate?

AminoGenesis Skin Cap Products
Firstly, AG has a controlled viscosity, which becomes less and less viscous as shear force is applied. Secondly, the electro static properties are correct and compatible with the skin's natural electro static charge. Thirdly, AG temporarily reduces skin surface tension to allow penetration. Lastly, the molecules in the entire product are small enough in size and weight to allow penetration.
