While carriers continue to expand their coverage areas by adding more towers on land, water showcases a hassle for providing adequate coverage for the passengers on boats. To deal with this problem specifically, cell phone boosters are designed wherein they take weak signal from land based towers, amplify it and broadcast it to the passengers on the boat. For a better and faster reception while docked or out on the water, the best option for the passengers would be a marine cell phone signal booster. A marine signal booster works by using an external antenna mounted on the boat which receives a cell signal from the closest tower, that is then passed to an amplifier, and then broadcast the boosted signal to the cabin via an inside antenna. The system also works in reverse when a call is being placed from a phone on the boat.
The three major prominent marine signal booster kits being the SureCall Flex2Go Marine Kit, that boosts 2G and 3G for most major carriers, the Wilson Mobile 4G Marine Kit, which boosts 2G, 3G and 4G LTE for most major carriers, and the Cradle booster, which is meant for only one phone at a time. The Wilson Mobile 4G Marine Kit boosts voice calls, 3G data and the new 4G LTE networks for the major carriers in North America to the inside cabin of the boat or marine vehicle. It has the strongest mobile amplifier allowed by the FCC, but if there is a very weak outside signal, the coverage area may extend only a few feet from the inside antenna.
The Sleek 4G cradle booster will boost the 2G, 3G and 4G LTE signals of all major carriers for one individual device at a time. The device should generally sit in the cradle at all times to receive boosted signal, hence requiring speakerphone or a Bluetooth headset for voice calls. The SureCall Flex2Go Marine Kit normally boosts voice calls and 3G data to the inside cabin of the boat or marine vehicle. It is believed to have the strongest mobile amplifier allowed by the FCC. The coverage area extends only a few feet from the inside antenna if there is a weak external signal.
Important point to be noted is that a marine signal is solely meant for its use within the boat living area and not the deck. If a booster is being used on the deck, then the signal from the internal antenna can be transmitted back to the external antenna, causing oscillation or feedback, which will immediately shut down the system. A marine signal booster provides greater convenience for voice calls and data usage, as well as peace of mind in case of emergency situations.
