There are two kinds of personal trackers available in the market. Ones that uses cellular signals, they operate using a mobile phone carrier and another which uses radio signals. A major disadvantage of the former is that that they work only in areas where there is 3G mobile phone coverage and in addition, have an ongoing service charge for the tracker. Radio wave trackers do not have a service charge but have a longer range and the signal transmission is limited to a handheld receiver. Though they have their pros and cons, these devices are almost indispensable in today’s fast paced world.
