No, the frequency isn't necessarily all that different. Some 4G Bands are even below typical 2G/GSM Bands.
The major difference is how the multiple access and Modulation is done.
2G uses short, narrowband, high power bursts. It's the interval of these bursts that causes the interference, not the carrier frequency.
