Power increase - meaning the total amplification of a repeater with Logarithmic scale a 30dB gain represents a one thousandfold signal However, since the decibel scale is measured on a The operators) offering gain around 100dBm (ICE function is welcomedĪs an improvement of the radio isolation between donor and serviceĪntenna). High-power models (not home usage - smart and expensive technology of Many of the more expensive models provide over 50dB.
Models (typically band selective) now provide 20dB - 50dB gain and
Suitable for commercial as well as home use.Īlso, something about technical theory about amplifiers:Īll models will include a signal amplifier. Multiple cell phones to use the same repeater at the same time, so are The more advanced models often also allow The signal, and retransmits it locally, providing significantly Signal, which is then transmitted to an amplifier unit which amplifies Use an external, directional antenna to collect the best cellular Rebroadcast cellular signals inside the building. These are similar to the cellular broadcast towers used forīroadcasting by the network providers, but are much smaller, usually Reception antenna, a signal amplifier and an internal rebroadcastĪntenna.
The wireless telecommunications industry, is a device used forīoosting the cell phone reception to the local area by the usage of a This means that the antena now is irradiating the double of the signal is was irradiating before(in this case 3dB up).Ī cellular repeater, cell phone repeater, or wireless cellular signalīooster, a type of bi-directional amplifier (BDA) as commonly named in It boosts the signal that feeds the antenna, I mean, instead of going 10 power unit(just exampling, it is actually messed on miliWatts or dbm) to the antena, the amplifier now boosts it to 20 power unit. If the booster is connected to the same antenna as before, how could Just on the link you pointed there is a "How it works" link.
