We are just about finished with our new iPhone app for Tuner2. (More on that interesting tidbit in a later post.) It performs flawlessly around the LA basin where AT&T 3G coverage is good. The question is, though, how would it perform in the middle of the Mojave? Since I had to head to CES anyway, I got the chance to find out.
Last year going to NAB 2008, I created a baseline for myself using the Sprint phone. Its performance was pretty spotty once you left the metro. The Tuner2 app on iPhone was a completely different story. I won't say it was flawless, but I was able to listen to Radio Paradise (24Kbps aacPlus) with only 1 or 2 hiccups going up the Cajon pass and all the way out to Fort Irwin/Yermo and the agriculture checkpoint.
After that, I had to take a break to make some phone calls. Similar to the Sprint experience, the iPhone was pretty spotty once I returned, but picked up again at Baker and was solid once more when I came into view of the Nevada state line. Driving around Las Vegas to and from the show, it was just as solid as "normal" broadcast radio. (Broadcast radio, BTW, crackles more than you think if you pay attention to it.)
It is interesting to note that the performance of the Tuner2 iPhone app is inverted from Sirius XM satellite radio receivers. In the urban areas, the scatter creates dead zones for sat radio (especially for Sirius, which seems to have a weaker ground repeater network.) I was in a rental car near Washington DC recently and the sat radio in the car went silent as I waited for the light to change under an overpass. In the desert, the lack of obstructions gives you good sat radio reception. For 3G (AT&T and Sprint alike) the urban areas are well covered and things get spotty when you head out into the desert or rural areas.
Of course, in the end there is no comparison since we spend most of our time driving in the metros and more importantly, the variety of what you can get via the Internet far eclipses the programming on satellite radio.
