Border blasters were an interesting phenomenon, but they are dependent on running on AM in order to get the kind of distance you describe. FM won't travel that far, no matter how much power you throw into it. It simply won't travel over the horizon except under rare propagation conditions.

And, to be clear, it's not the AM-ness or the FM-ness that makes it so, but the fact that AM broadcasting is done on some pretty low frequencies, around 1 MHz, and these will both diffract and reflect to reach places that an FM signal, two orders of magnitude higher in frequency, just won't go (though notably, the FM band is comparatively superior at getting inside of buildings).

So he's building a "cloud platform" for cars and he didn't bother checking to see if fast internet was available BEFORE purchasing the lease?

FTFA:

Katta’s Internet odyssey began on April 10, 2015 when he checked Comcast’s website to determine whether business Internet would be available at his company’s office in the Clyde Avenue Business Park. The website informed him, “Comcast Business is available at your address.” In fact, the website still provides that same message to this very day, albeit with some fine print that says customers have to “Call a Comcast sales representative to explain availability in your area.”

Over the next 10 days, Katta told Ars, he signed a lease for the new office space and spoke on the phone with two Comcast representatives. Each confirmed that SmartCar would be able to get Internet service.

That appears to be in the correct order, so I'm not sure what you're on about.

Comment Re:I'd prefer long range (Score 1) 99

Exactly. Let me offer some anecdotal examples.

My real world experience is that in my relatively flat residential neighbourhood, 400m is about the limit between handheld UHF radios (tried on both 450ish and 915ish MHz frequencies), ranging from 500mW to 7W. VHF (around 140-155 MHz) goes a little further under those circumstances (there are lots of trees in my neighbourhood, and trees have a larger negative impact on UHF than VHF).

At the same time, put one end on top of a hill, mountain, tower, building, or other tall thing, and the range, even at the same power level, becomes what they say on the package and often then some.

(Before someone asks, because radio nazis are everywhere, yes, all my radios are legal. I am a licensed ham, but also use MURS and FRS as well as some proprietary spread-spectrum radios on 915 MHz)

Sort of.

The way to get around it is to define the parameters tight enough to get what you want. For instance, adding this language: "The device shall feature a 4.3" AMOLED display. It shall be compatible with all CDMA networks, 802.11 a, b, g and n, and LTE bands 25, 26 and 41. It shall use the Android operating system and support one Micro-SDcard. It shall require a SIM for LTE connectivity, but not for CDMA connectivity." will pretty much knock things back to one specific version of one specific device, that being a Samsung S4 Mini that has been configured for Sprint (an SPH-L520).

Some manufacturers will even provide you with the verbiage to get exactly one particular specific product of theirs and no other.
