Eric Schlaepfer writes "Here's another great toy for your wish list! ICOM manufactures the highly advanced IC-R3 portable scanner/television set. Besides picking up radio stations in the frequency range of 0.495-2450MHz, the IC-R3 also receives regular television signals, amateur television, and wireless security camera signals."

There are several bands in the US, Europe, and Asia for cellular service; few overlap. CDMA isn't always at 1900.

The problem is that it used to be legal to build and sell a general coverage receiver that covered DC to Daylight. There were laws that restricted what you could do with some of signals you received, such as prohibiting disclosure to third parties, but the general principle was that any American was free to listen to anything transmitted on the public airwaves.
Enter cellular telephony (AMPS), which replaced the old mobile telephone service. Eventually, some bright bulb rediscovered that cellular telephone conversations were transmitted via UHF FM radio signals, without any encryption or signal security. Anyone with a UHF FM receiver, or an older VHF/UHF television set, could listen in on cellular phone calls. When the word got around to the general public that cellular calls were not private, the CTIA (cellular trade association) went nuts. This was a public relations problem that could hurt their sales and profits. Rather than fix the problem of broadcasting cellular calls in the clear, their "solution" was to lobby congress for a law that would prohibit sales of receivers that could listen to cellular telephone frequencies, and would criminalize the act of listening to a cellular telephone call. This was the first time that congress had made it illegal to listen to a radio signal. Of course, none of this made a damn bit of difference as to the security of a cellular telephone call. It just provided the illusion of security, which was all the CTIA was willing to pay for. It also gave a big stick to politicians who were embarrassed by the public disclosure of the contents of their cellular telephone calls. They could demand that the government prosecute the "criminals" who had the gall to embarrass them by publicizing their dirty laundry.

I'm a long-time HAM, and I also have one of the old scanners that gets cellular (old Radio Shack model), and many can be modified to receive cellular signals (though this is illegal... do a google for scanner mods and you'll see how easy it is).
The Cordless phone prohibition came later... I can't recall the year, but a hue-and-cry came about from people scanning the old 49.x mHz cordless phones. Naturally, the newer 900 mhz and 2.4ghz models with spread-spectrum require a bit more technical expertise than the old turn-on-the-scanner-and-listen routine. Even the Donald-Duck-sounding "scrambled" ones used a simple frequency inversion routine that you could easily decode (probably a DMCA violation these days).
The trunking radio systems put a brief dent in the scanning scene, but you can even get scanners to track those now.
Years ago, a buddy of mine lived in an apartment, and had an enormous dipole tacked up in the attic of his building, tuned specifically to the 49.x band... got every cordless phone for blocks. It was a rough neighborhood, so he sometimes got to hear the drug dealers doing business, and the ex-cons talking to their parole officers. I suppose that's the lazy man's way to get to know who your neighbors are BEFORE you invite them over for a neighborhood BBQ. However, before you run out and set up a similar rig, I can tell you that most people's conversations are relentlessly boring. Nosy, boring, and illegal... hardly worth it.

Its sensitivity is lacking, so unless it encounters a very strong video signal (especially on 2.4GHz, where a lot of wireless cameras broadcast their signals), do not expect a very watchable or even decodeable picture.
Secondly, the video screen eats the hell out of the battery life. You'll find yourself reaching for the AC adapter quite frequently. This device tends to use the LCD screen to display a lot of configuration/tuning information, even in non-video mode, so beware if you buy this to use as a general-purpose scanner.
After 10 months of R3 ownership, my feelings are still mixed. It's pretty cool to walk around and stumble on 2.4GHz video, especially from wireless security cameras, but as a general-purpose scanning receiver or for attempting to receive TV DX in these skip-prone months, it falls sadly short.

It's very difficult to create a tuning circuit (which all receivers have) that is very sensitive across a wide range of frequencies. I would guess that this receiver is most sensitive in the VHF/UHF or even 800 MHz bands. From the specs, it looks like the upper end of the range for the R-3 is 2540 MHz (2.54 GHz), which isn't necessarily the clear-cut end of receiving capability for the product, it's just where the engineers (or marketers) decided to print the cutoff because the sensitivity drops off quickly somewhere around there.
The solution might be a 'transverter' device which essentially acts as another IF stage in the receiver, mixing all input signals with a fixed frequency. The result is several sidebands, at least one of which is offset from the input signal by the value of the fixed frequency.
Example: You want to see a video transmission on 2.450 GHz, but the receiver is not sensitive there. You build a little circuit that uses a diode to mix the incoming frequency with a 1000 MHz signal generated by a crystal (good luck finding a 1GHz crystal
This technique is sometimes used by folks who really want to break US law and listen to cell-phone conversations. Nevermind that nowadays analog calls are nearly extinct. By law all receivers sold in the US must block tuning in of the cell-phone frequencies, which are around 850-900 MHz. (That's different these days with digital, but we're talking about analog.). Since nearly all receivers of FM audo use an IF (Intermediate Frequency, like the 1000 MHz signal we used above) of 10.7 MHz, users found they could tune to some multiple of 10.7 MHz below or above the cell phone frequencies and hear the 'images' of the calls. Nowadays scanner manufacturers extend those blocked frequencies to the image frequencies as well, so most folks are out-of-luck unless they build their own receiver for 850 MHz.

I know it's a battery hog but as for the signal strength issue on broadcast TV reception you might want to give your R3 a better antenna. If you are particularly aiming for UHF stuff, get one of those 800 Mhz antennas.

If you're running it at home on an AC adapter, then you're okay, but mobile is kinda limited with the effect video reception/display has on battery life.
Then again, if you're the kind of person that drives around with their laptop searching for wifi networks, you might be used to that kind of battery life already.
