milliwatt

The digital milliwatt is used in place of separate test equipment.

For example, dBm indicates power measurement relative to 1 milliwatt.

The limit is increased from 1 milliwatt to 1 watt or a thousand times increase.

Signal power is often measured in dBm (decibels relative to 1 milliwatt).

Note 2: 0 dBm0 is often replaced by or used instead of digital milliwatt or zero transmission level point.

Wireless engineers talk about signal strength in terms of power: dBm, or decibels to the milliwatt.

"One-tenth of one percent of one milliwatt is one microwatt, isn't it?

The digital milliwatt is stored in ROM.

Power levels vary widely (from 1 milliwatt in a Bluetooth node to 1 kilowatt in a microwave oven).

A typical laser pointer outputs about five milliwatts of light power, whereas a typical hearing aid for people uses less than one milliwatt.

Both of the above types of beacons usually include an auxiliary 25 milliwatt beacon at 121.5 MHz to guide rescue aircraft.

The project entails a number of 40 milliwatt beacon transmitters at a frequency of 7.023 MHz being operated by amateurs across the country.

In the Bell System, central offices provided this type of service on a dedicated telephone number (102 type Milliwatt line) for remote subscriber line testing.

FRS devices have a maximum power of watt (500 milliwatt) effective radiated power and integral (non-detachable) antennas.

For example, dBm indicates a reference level of one milliwatt, while dBu is referenced to approximately 0.775 volts RMS.

Billing itself as the "hundred-thousand milliwatt of the River City", KAGU broadcast a 100 watt signal throughout Spokane.

In digital central office installations, the Milliwatt test facility was implemented using a synthesized version of the 1004 Hz signal, see digital milliwatt.

"It's going to take every milliwatt of power we've got in this hookup to tap his beam, but I think I've got Helmuth direct instead of through a pirate-ship relay!"

"This will give us more processing per millimeter and milliwatt than anything else out there," predicted Mr. Lange, zeroing in on the space and energy constraints that most device designers struggle with.

For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dB V/m) or in decibels above a reference level of one milliwatt (dBm).

Class II lasers, from half of one microwatt to one milliwatt, used as lecture pointers and for laboratory demonstrations, are dangerous only to someone who stares directly at them for longer than one-quarter second.

Now a researcher at the Massachusetts Institute of Technology has devised a processor for cochlear implants that he says consumes only about half a milliwatt, one-tenth of the processing power of current devices.

Traditionally associated with the telephone and broadcasting industry to express audio-power levels referenced to one milliwatt of power, normally with a 600 ohm load which is a voltage level of 0.775 volts or 775 millivolts.

This is particularly important for some units of measure - for example a hearing aid requires about 1 mW (milliwatt) while the central air conditioning unit in a large office block might require 1 MW (megawatt).

A dBm of zero (which is next to impossible unless you suddenly find yourself climbing halfway up a tower) would be one milliwatt of power, and for every 3dBm going down into the negatives, that power is being cut in half.
