You could never get any further from your car than the length of the handset's cord.

Why do mobile phones use microwaves and not radio waves?
Microwaves ARE radio waves, just very high frequency radio waves.
Some newer phones use a higher frequency (800 to 1900 MHz, aka ultra high frequency) to avoid interference from other broadcasting signals and from various types of machinery.
* The term "microwave" refers to wavelengths that correspond to frequencies from about 1 GHz (1000 MHz) to 30 GHz, which has been used for line-of-sight communication relay links. Cellphones do not use the same frequencies. (3 to 30 GHz is designated "super high frequency.")
it sounds like hes playin games, he might hav a really good explanation but i doubt it, or he may not have the heart to tell u. if i was u i wouldn't even text him sayin ur not txtin him agen, if he really likes u then he will txt or email u, if u havnt heard nothin in a couple of weeks then u no how he really felt. thing is you never chase a guy as now hel feel you were being needy and that makes guys run a mile, chill out and don't scare them away

How can you find out who is harassing you on your cell phone when they are also calling from a cell?
you can't cell phone companies have privacy laws they have to follow. If the harassing was considered dangerous the police can get involved to get the name of the person.Your best and easiest solution is to just change your cell phone number and be cautious of who you give your new number to.
ANSWER but this isn't entirely impossible. if you give your number to your friend and then your friend gives it to another person who says they only have good intentions, your number can spread like wildfire because the other person may use it for "cruel intentions".
Can a power signal be an energy signal?
a signal can never be both energy & power signal because they are mutually exclusive
How do microwaves disperse during path loss between communication towers?
Because of the wave nature of electromagnetic waves, it's impossible to radiate
them from a 'launching structure' that has finite dimensions, and expect them
not to spread wider as they proceed over a great distance. So we must picture
any electromagnetic transmission ... whether it's light, radio, radar, microwave,
X-ray, etc. ... as a cone of energy as it proceeds from the transmitter, beginning
with a small cross-section as it leaves the launcher, and growing wider and wider
as it proceeds.
Realizing this, we now have a constant, fixed amount of power, propagating
across a surface area that gets bigger and bigger as we move farther and
farther from the source. So for a receiving antenna of any given size, it makes
sense that the farther the receiver is from the source, the less signal power
it's able to intercept, since that power is spread over a progressively larger
area as the distance increases.
People will also hasten to mention that there are many things all around in
the natural environment that absorb power from the signal, such as trees,
buildings, atmosphere, rain, clouds, soil, etc. They are correct, but these losses
are only a very small part of the weakening of microwave signals with distance.
By far the greatest factor is the geometric spreading with distance, described
above.
How do you dial a UK cell from the US if 011-44-79xxxxx doesn't work?
In your question, it looks like you didn't dial all the digits. A UK mobile phone number, as dialed from a US or Canadian landline phone, is of the form 011-44-7AXX-XXXXXX-#, where A=4,5,7,8,9 and X is any digit. Pressing the # key at the end tells the telephone switch not to wait for any more digits.
More generally, to dial any UK telephone number from the US, substitute the prefix 011-44 for the trunk prefix 0 of the UK domestic telephone number.
