It depends on six factors:
1. Transmitter power,
2. Transmitting antenna,
3. Receiving antenna,
4. Receiver sensitivity,
5. Frequency and type of operation,
6. Any land or obstacles between the two radios.
The deep space probe that passed by jupiter, neptune and the outer planets was still sending from billions of kilometres away.
A small iPod FM transmitter, such as the ones used to broadcast fro an iPod to a car radio have a range of less than ten metres.
2.4 GHz Wi-Wi can have a range as small as one room (depending on building construction) or hundreds of kilometres with large antennas sited on mountain tops.
Generally? Don't believe sales hype - ask somebody who uses similar equipment, or ask to test the gear yourself under the conditions you expect to use it in.

Another contributor provided a benchmark:
As of December 2010, the Voyager I spacecraft, launched by NASA in September 1977,
is still operating, and communicating with earth by radio, from its position on the 'edge'
of interstellar space, presently about 10.6 billion miles from us.

Do radios need signal?
no
How do motorola 2 way radios transmit a signal?
Two way radios should be set at the same frequency. Then, 2 or more persons can communicate with each other via those radios, by pressing buttons and speaking.
What frequency do two way radio use?
They are not always different. If the communication is between two radios directly, only one frequency is used. This is called simplex operation. It works fine because only one radio is transmitting at a time. When two radios communicate through a repeater to increase the distance, the repeater must simultaneously receive from one radio while retransmitting the signal to the other radio. A single frequency would not work because the repeater would only hear its own output. So, two frequencies are used. This is called duplex operation. The above information is partially incorrect. Simplex and duplex do not refer to how many frequencies are used. They refer to the way traffic (data and voice) are sent and received. The reason for different receive and transmit frequencies is for retransmitting (like stated above) and for satellite communications. Satellites receive on one frequency, then modify, amplify, and retransmit the signal on a different frequency to prevent bleedover.
Will Sirius Satellite Radios work downttown surrounded by high rises?
Yes, the signal will not be interrupted by tall buildings.
Where can one buy cheap DAB radios?
DAB is a digital radio that can pick up a digital broadcast signal. Places like Tesco's, Sainburys and Argos usually have DAB Radios in stock at very reasonable prices.
Do radios need signal?
no
Why do radios and communication equipment fail?
Signal interference, blocked signal, antenna problems or electrical faults.
Traveling with Motorola two-way radios?
Yes, 2 way radios will operate without cell-phone coverage. They transmit and receive their own signal, so they will be fine. The range varies depending on the quality of the radio, but most standard sets are good to about 1 mile.
Where does wireless transmit and receive signal from?
It has an access point which transmit signal to the client and receive.

What are the advantages that digital radios have over FM and AM radios?
Digital offers better quality, particularly in marginal signal conditions.http://www.thenakedscientists.com/HTML/interviews/interview/1000068/

How far does the signal reach for a cb two way radio?
Typically, the signal that the cb two way radios can transmit would go up to a few miles on a good day. However, the likelihood is more likely that the signals will only travel one or two miles.
Do radios have to have an earth connection?
When a radio receives a signal, that is not the same as the creation of an electric circuit, and no electricity needs to be returned by way of the ground, as in most forms of wiring. If you were floating in the air, suspended by a hot air balloon, you could still receive radio signals. An earth wire enhances the signal strength. Large broadcast transmitters still use an earth for efficiency. Modern, portable radios, have much improved tuning and detection circuits and so do not need an earth to work. Early radios and crystal sets, need an earth because of the inefficiency of the tuning circuits.
How far is the cape hatteras signal visible?
how far is the signal visible in miles
Can I use an existing radio with XM radio?
Legacy radios receive RF radio signals.Satellite Radios operate at the Microwave spectrum and require completely different receivers.
Will Sirius Satellite Radios work downttown surrounded by high rises?
Yes, the signal will not be interrupted by tall buildings.
