Helios ® RF Repeater sistem yang dirancang untuk memecahkan masalah sinyal ponsel lemah, yang jauh lebih murah daripada menambahkan Base Station baru ( BTS) . Sistem operasi utama Repeater RF untuk menerima sinyal rendah-daya dari BTS melalui frekuensi radio ( RF) transmisi dan kemudian mengirimkan sinyal diperkuat ke daerah mana jangkauan jaringan memadai. Dan sinyal mobile juga diperkuat dan dipancarkan ke BTS melalui arah yang berlawanan.

Sesuai dengan kebutuhan Anda untuk frekuensi kerja, Anda dapat memilih jenis Helios ® RF Repeater:

Band Selective RF Repeater Sistem: untuk memperkuat semua sinyal di seluruh band ( bandwidth Berbagai tersedia atas permintaan)

Wireless RF Repeater Channelized
Sistem: untuk memperkuat sinyal ditransmisikan hanya oleh 1 atau 2 atau disesuaikan 4 atau 6 atau 8 channel ( Sebuah band sempit dengan frekuensi pusat disesuaikan)

In-built AGC & ALC function be able to ensure easy installation without setting
Unique max AGC60dB firmware to ensure stable operating on moving platforms such as ship or trains
Compact size and light weight, easy to install on wall or pole
High working gain as Min. 90dB
Output power + 30dBm - + 43dBm for large coverage application
Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
2 RS232 or RJ45 ports provide links to laptop for local setting and monitoring by built-in web interface.
Built-in wireless modem ( Option) for remote monitoring by SMS, GPRS or TCP/ IP.
Details repeater parameters and status can be monitoring by built-in web interface, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR etc.

High gain linear power amplifier technique with reliable performance

Applications:

To expand signal coverage of fill signal blind area where signal is weak or unavailable.

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

The RFR is mainly applicable to such case:

The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than -70dBm;
