30W-ICS Repeater: Interference Cancellation System (ICS) Repeater is a personal network enhancement device with inbuilt Interference Cancellation System ICS Repeater system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low power signal from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.

A DAS is a system of managed hubs and remote antennas that distributes a wireless signal to a series of connected indoor or outdoor multi-band, multi-technology radio heads. ... A main hub takes that signal, digitizes it, and distributes it to other hubs and radio heads via a high-bandwidth fiber optic network

Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc. Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.

The RF front-end stage of the communication system is composed of passive devices such as a filter, a duplexer, a power combiner, an RF connector, and an RF switch. These passive devices are designed to maintain the possible linear characteristics in the operating range, but they have practically nonlinear characteristics. Passive intermodulation occurs when two or more different frequencies are used as inputs to a passive device having nonlinear characteristics. This phenomenon is called Passive IM (PIM). Intermodulation (PIM) signals are added as unwanted noise to an uplink band in a mobile communication system, which is a major noise source that deteriorates the signal to noise ratio (SNR). Therefore, the intermodulation (PIM) signal, which may cause a lot of losses in terms of operation, maintenance, and frequency use efficiency of the mobile communication system equipment, should be removed. A system for removing an intermodulation (PIM) signal existing in an uplink band of a mobile communication system is called a PICS (Passive Intermodulation Canceller System).

The Single Band LTE Repeater is a cell phone signal booster system made up of antennas, cable and a signal amplifier that takes an existing cell signal, typically found outside your home or office, amplifies the signal and then broadcasts it to an inside area that has a weak or no signal.In order for the system to work, there must be an existing, stable outside signal for the system to receive and amplify It can be applied at meeting rooms, conference rooms, museums, galleries, theaters, concert halls, churches, temples, restaurants, classrooms, training centers, factories, banks, trains, bus and more Places that require silence, confidentiality and information security

A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals. The repeater device features easy installation & operation, build-in indoor antenna and no interference. It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.
