Types of Cell Phone Boosters
Cell phone boosters are either Wide-Band or Carrier Specific. Wide-Band has some limitations as they are regulated to operate on specific frequencies and bands. This limiting requires an already high performing outdoor signal and a very specific installation. These boosters operate as Verizon signal boosters, AT&T signal boosters, T-Mobile signal boosters, and Sprint signal boosters all at the same time. This boosts the signal for all of those carriers on all of their 2G, 3G, and 4G LTE networks and it will even work with the new 5G networks when those are released.
Carrier Specific boosters do not face these limitations as they very rarely interfere with other signals. However, as their name implies they only operate with specific carriers. This has many limitations. First and foremost switching carriers will interfere with the signal boost provided by a carrier specific booster. Also, any guests or visitors you have over that do not share your network and carrier will not receive the signal boost.
While it is often tempting to use the carrier specific boosters because they are often more affordable many signal booster users prefer to use wide-band cell phone signal boosters.
