    wireless network
  • (Wireless Networks) Connection of modules together to transmit information without the use of physical connection by wires.
  • (Wireless networking) For a modest investment, you can set up Internet access in your home or office, and broadcast it to computers in other parts of the building without running wires.
  • Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes are implemented without the use of wires.
    signal strength
  • refers to the total amount of power of RF received by the receiver. This is divided into useful signal, referred to as EC/I0, and the noise floor which is useless.
  • In telecommunications, particularly in radio, signal strength refers to the magnitude of the electric field at a reference point that is a significant distance from the transmitting antenna. It may also be referred to as received signal level or field strength.
  • Signal Strength is the strength of the radio waves in a wireless network.
    meter
  • A race over a specified number of meters
  • The fundamental unit of length in the metric system, equal to 100 centimeters or approximately 39.37 inches
  • measure with a meter; "meter the flow of water"
  • the basic unit of length adopted under the Systeme International d'Unites (approximately 1.094 yards)
  • any of various measuring instruments for measuring a quantity

Did you know that your cable signal gets stronger as the weather gets colder? Here's a graph of signal strength on my cable modem from the last month. The bump at the end comes from the cold snap in the last day, where it was around 32°F (0°C) at 6 PM yesterday, then got down to about -5°F (-21°C) around 12 hours later. You can also see that the temperature had been getting warmer gradually in recent weeks. The orange peaks toward the middle of the graph were occurring around 7 AM on cold mornings in February where the temperatures were around zero degrees Fahrenheit. Blue is transmit power (lower is better). Orange is receive power (higher is better, though it shouldn't really go past +8 or +9). It appears that the received signal more than doubled in strength (since dBmV uses a logarithmic scale, as far as I can tell). Roughly the first half of the graph covers a period when I was having lots of trouble with my cable signal. About a week into the graph, I had someone come by to fix it, but it seems that the issues weren't fully resolved until about a week later.

Here's a graph of signal strength on my cable modem from the last day, where it was around 32°F (0°C) at 6 PM yesterday, then got down to about -5°F (-21°C) around 12 hours later. At one point around 2 AM, the cable modem went offline for a few minutes -- it seems that either it or the upstream device wasn't able to keep up with the changes. Blue is transmit power (lower is better). Orange is receive power (higher is better, though it shouldn't really go past +8 or +9).
