Unfortunately, I do not think there is a specific length by which wireless audio transmitters transmit and after searching the web for a long time, I have not found anything of it.
how far are you able to access your wireless
FM GPS Transmitters use radio frequencies to track and locate objects from far away. They are more so common in vehicles and cellphones: http://www.gpstrackingdevice.net/Accurate-Tracking-With-FM-GPS-Transmitter-Devices.html
It will depend on the strength of the signal. It will also depend on if you are using wireless g or a wireless b access point for your wireless services.
100m
Don't get dazzled. It's radio. You have a radio receiver in your car. The three XM satellites and about 900 ground repeaters have radio transmitters. They transmit radio from the transmitters to the receiver in your car. Except for some updates in technology, the frequencies used, and the fact that you have to pay for it, as far as you the driver are concerned, XM is the same thing that's been going on since Motorola first took a radio out of a kitchen and put it in a car.
about 10 meters
It means your Netgear wireless router or Netgear wireless card (your computer) are too far from one another for the wireless connection to work.
You are too far from the router.
100 ft
You need a wireless router and if the lake is far a wireless range booster.
The range of a wireless microphone will depend on the product itself. The normal range of a wireless microphone may vary from 300 feet to a 1000 feet.
Wireless n has a highter bandwidth and range. Wireless n is therefore recommended. Note that the download speed on most internet connections is far less than what both wireless n and wireless g can handle.
