This if of course, assuming proper shielding was used in the cell phones and hotspots to reduce RF leakage.

Sorry, Solid, That is not the way interference works. The third harmonic of 1700 MHz is right in the band. All it needs is a non-linear mixer and voila, interference. Loose aluminum hardware makes a great non-linear mixer. High power RF mixing in the input to a receiver can also produce the same effect. 800 + 2*2100 also comes out on a frequency that can interfere.
