Answer
the first cordless phones operated around 48Mhz as well as baby monitors and the like...and were easy for people to listen in on your conversations.. it was not uncommon for a baby monitor to pick up your conversation, or for 2 cordless phones to hear each other....

the 900 Mhz phones solved some of those problems... but people with radio scanners (police scanners) could still listen in on your calls...

DSS technology stopped that... and many newer 900 Mhz phones come with DSS...

also most 2.4Ghz phones have DSS or FHSS, aside from that, most radio scanner equiptment only goes up to 1.3Ghz - however these phones may interfere with WiFi

5.8Ghz phones also normally come with DSS or FHSS... and again are outside the range of most radio scanners.... however, because they are a higher frequency the range is less...

DECT phones operate within the 1.9Ghz range, are immune to interference from other devices, and provide the best range, clarity, and security...

so the only way that a neighbor can listen in to your conversation with a cordless phone that you purchace today would be if you bought a 900Mhz phone that did not have DSS....

which of the following is not an example of radio technology? answer choices below!?

a.baby monitors b. cellular phones c. internet d. both b and c e.all of the above.


Answer
Dear Andrea M.,
Answer is a. baby monitors. Baby could be monitored by CCTV (Close Circuit TV). While cellular phones and internet are examples of radio tech utilization. Cellular phones works use radio wave in frequency around 800, 900, 1800, and 1900 MHz, while several internet connections use radio wave as well, eg. through satellite, or through cellphones (EDGE, GPRS, 3G, 3.5G).
Thank you very much Andrea M.
