HELIOS Digital Off-Air Repeater

Advanced Bi-Directional Amplifier (BDA) devices useing SDR (Software Defined Radio) technology for precise radio traffic management. Unlike simple amplifiers, Helios digital models offer full signal control at the level of individual channels and timeslots. The device operates as a wireless connection to a base station (BTS) without the need for fiber optic cables: - Donor Antenna: Receives the signal "over the air" from the base station. - Digital Filtering: Based on an FPGA and DSP platform, it ensures high separation from adjacent channels and minimizes interference. - Service Antenna: Distributes the amplified signal to a remote area (or inside buildings, tunnels, underground parking lots, shopping malls, etc.).

Independent Processing: Supports up to 16 independent channels.
Timeslot Control: AGC/ALC and Squelch operate independently for each channel and each time slot (per timeslot).
Minimum Latency: Group Delay is just 12 μs, which is crucial for maintaining synchronization in TDMA networks.
Gain and Power: Minimum operating gain is 85 dB, and RF output power can range from 30 dBm to 40 dBm, depending on selected option.
