Digital Dual Band RF Repeater
Helios® Digital Dual Band RF Repeater is a cost-effective and intelligent solution that solves the last mile coverage problem, and dual band operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz and supports all major wireless technologies include GSM, EDGE, DCS, CDMA, UMTS, LTE FDD.
The design adopts SDR (Software Defined Radio) technology based upon our FPGA & DSP (Digital Signal Processing) platform. It enables on-the-fly filter & Bandwidth configure/upgrade by software without expensive hardware upgrading. Built-in individual Gain and ALC setting for each sub-band for multi-technology application (e.g. GSM/UMTS) for single or multi-operator applications.
The Repeater is connected via coaxial cable to a Donor Antenna and Service Antenna or DAS. The Donor Antenna is placed outside the building where it has access to a BTS signal, and the Service Antenna or DAS are placed in the building where they can extend radio coverage to the areas lacking coverage.
Key Feature
