Just my 2 cents on WiFi...
Solo uses 2.4 GHZ radio, and uses the WiFi protocol so that it can connect to other things (like tablets). I know it sounds like others don't use this same radio frequency and technology, but things like "Lightbridge" are really the same under the hood.
They work the same wirelessly. In the case of DJI, after the video is transmitted wirelessly to the controller, they make a USB (serial) connection from the controller to the tablet. Using this 2.4 GHZ frequency and technology is necessary for a few reasons, some of which have to do with what frequencies are available and can be used without a license, and others having to do with radio signal propagation properties allowing the data and the distance.
Regardless of what it is called though... It is the same frequency, with the same interference, and limitations, etc..
As an example, the only radio difference between stock Solo and Phantom is the power output of the radios. I am not positive on the exact details, but I believe the stock radios in Solo are 500mw, but are degraded to 400mw in setup (I could be wrong on these exact details) and DJI uses 800mw radios. This results in the distance differences. Simple as that.
For what it's worth, add on antennas greatly improve Solo performance, have less dropped signals, etc.. They range form $8 to $100. The radios in Solo (both controller and copter) are also standard min PCI cards (different than DJI which is proprietary) and so can be swapped for standard 800 mw mini PCI cards without any other changes. These cards are in the $30 range.
People that do this regularly report distance capabilities of 2+ miles. Standard WiFi booster amps, box antennas, etc. can also be added, and people that do that have reported distance of greater than 5 miles (though I defy anyone to be able to see line of site that far).
There is nothing wrong with using "WiFi" and electrically (and due to regulations) there are few alternatives. If you are having problems at very short range, it "could" be interference, but more likely there is just something wrong. It is impossible to know what it is without looking deeper, though there is a set of calibrations that are known as "stick calibration" (but are actually much more) that have fixed this problem for several people.
