Most of wireless adapters have the same range. There are more expensive versions which support longer range. You need to read the manual for your laptop to find out the range for the wireless adapter you have. Also very often advertised range does not lay even close the real life value. For the most applications and cases built-in adapter should do just fine.

By 4g technology, I am assuming wireless internet access. MacBook's come with Wifi built in but not with 4G. Since there are several 4G service providers and each has a proprietary USB adapter, it is better not to have the 4G technology built in to the MacBook.
