Explanation
The sentences read that 3G is a long-range technology, high-bandwidth tasks cannot use 3G, Bluetooth is short-range, and Bluetooth is low cost.
The first blank is long, because 3G mobile networks reach over wide areas through cell towers.
The second blank is high, because activities needing high bandwidth exceed what 3G can supply.
The third blank is short, because Bluetooth links devices only over a short distance of a few metres.
The fourth blank is low, because Bluetooth is a cheap, low-power way to transfer data.
This gives the order long, high, short and low for the four blanks.
