What data communication technology uses low power radio waves to transmit data?

Answer 1

There are many data communication technologies that use low power radio waves to transmit data, including:

• * CDMA (used in most cell phones)
• * FM (used in Family Radio Service walkie talkie)
• * frequency-hopping spread spectrum (FHSS) (used in Bluetooth)
• * direct-sequence spread spectrum (DSSS), used in IEEE 802.15.4, which in turn is used by ZigBee, MiWi, 6LoWPAN, etc.
• * amateur radio operators often try "QRP" operation (very low power) with many different communication technologies: CW (Morse Code), AM audio, FM audio, PSK31 and Hellschreiber digital text chat, and etc.

Answer 2

From the way your question is worded, it seems that you're looking at a list of

choices, but not sharing the list. Our Department of Clairvoyance remains

shuttered and dark since the recent government shutdown, so without seeing

the list, there's no way for us to point out the correct choice from the list.

If the list includes 'Bluetooth' or 'Wifi', either of those would be a pretty good

answer. In fact, they're both good answers even if they're NOT on the list.

Answer 3

All of them.

Seriously.

Examples include:

AM radio, FM radio, TV, police radio, taxi radio, fire radio, sheriff's radio, ambulance radio,

live TV from our reporter on the scene, GPS, garage-door openers, microwave ovens,

keyless car-locks, cordless phones, cell phones, smart phones, Bluetooth, WiFi, WiMAX,

microwave communications links, mobile data systems, internet around the house from a

router in the basement, Sirius-XM radio, satellite TV, TV through the little dish on the roof

of the garage, short wave broadcasts from Radio Moscow, Muzak in the elevator or the

supermarket, phone calls from the airplane, pilot to tower, internet in flight, weather-

alert radios, and "Atomic" clocks and watches.

They're all using the technology that used to be called "wireless" a hundred years ago,

until some sharp young ad-man came up with the new snazzy word ... "radio".

Answer 4

Any wireless router, WiFi card in a laptop, Bluetooth ear-thingy, smart phone,

HD radio station, digital TV station, or modern microwave transmitter does that.

Answer 5

Yes, just like cell phones, televisions and radios, wireless networks use radio waves to transmit data.

Answer 6

Wi-Fi and Bluetooth technology.
