Wi-Fi antenna boosters provide a relatively inexpensive and practical alternative to paying for cell phone carriers' subscription programs. In urban areas where free Wi-Fi hot spots are fast becoming ubiquitous, a £13 booster might double or even triple the range of a laptop's Wi-Fi capability. For truly stellar performance that increases range by a factor of 10 or more, however, a slightly larger investment is in order.
