Nextivity CEL-FI GO G43 Complete Set – Multi-Operator LTE / 5G DSS Cellular Booster
This CEL-FI GO G43 Complete Set provides a professional solution for simultaneous multi-operator indoor cellular coverage. It is based on the Nextivity CEL-FI GO G43 and supports LTE, 5G DSS and 2G (GSM).
Unlike low-cost wideband repeaters, the G43 operates in a channelized, band- and operator-selective manner. Only the frequencies actually used by each mobile network operator are amplified – network-safe, interference-free and carrier-grade. This technical approach is the key reason why CEL-FI systems clearly outperform typical wideband solutions, especially in professional environments.
Complete Set Highlights
-
Multi-operator booster – supports up to 3 operators simultaneously
- LTE / 5G DSS / 2G (GSM)
- Supported bands: B1, B3, B5, B7, B8, B20, B28L, B40
-
System gain up to 100 dB (carrier-grade)
-
3× TELEVÉS PRO-5000 outdoor directional antennas (one per operator)
-
Combined indoor output signal via 2 server ports
-
Band- & operator-selective – not a wideband repeater
System concept – separate reception, combined indoor distribution
The CEL-FI GO G43 features three donor inputs, each connected to a dedicated TELEVÉS PRO-5000 outdoor directional antenna. This allows each mobile network operator to be received independently from the optimal direction and base station.
Inside the unit, an integrated combiner merges all amplified operator signals into a single combined output signal. This signal is then distributed indoors via two server antenna ports. No external combining or additional RF components are required.
Scope of Supply – Complete Set
-
1× Nextivity CEL-FI GO G43 multi-operator booster
-
3× TELEVÉS PRO-5000 outdoor directional antennas, each with 7.5 m fixed cable
-
1× TELEVÉS indoor antenna with 2 m fixed SMA cable
-
1× H155 coaxial cable, 10 m – SMA female ↔ SMA male
-
3× adapters: SMA female → N male
Flexible indoor antenna connection
-
Direct connection: indoor antenna connected directly using the 2 m cable
-
Extended connection: indoor antenna plus additional 10 m H155 cable for optimized placement
- Outdoor antennas are installed separately and aligned individually per operator
Coverage & Typical Applications
Typical indoor coverage: approx. 1,000–1,250 m² per system (depending on building structure, frequency bands and antenna layout).
- Office and administrative buildings
- Hotels and hospitality
- Retail and commercial properties
- Buildings requiring coverage from multiple operators
- Facilities with GSM-based emergency or legacy services
Notes
- Supports LTE, 5G DSS and 2G, but no native 5G NR (SA/NSA, e.g. n78)
- For true 5G NR mid-band coverage, we recommend the CEL-FI GO G51
- Operation of cellular signal boosters generally requires approval from the respective frequency holder
Optional remote monitoring & maintenance by Haider Telekom GmbH available (project-dependent, additional costs apply).
Haider Telekom – Why we deliberately rely on CEL-FI technology
As a specialist for professional cellular coverage solutions,
Haider Telekom GmbH deliberately relies on
channelized, band- and operator-selective systems such as CEL-FI –
and consciously not on simple wideband repeaters.
| Technical Aspect |
CEL-FI (Nextivity) |
Wideband Repeater |
| Amplification principle |
Selective & channelized |
Unselective across entire bandwidth |
| Operator separation |
Clean, controlled processing |
Uncontrolled mixing of signals |
| Network compatibility |
Very high (network-friendly) |
Highly dependent on environment & tuning |
| Signal quality |
Carrier-grade level |
Inconsistent |
| Long-term stability |
Very high |
Often unstable when networks change |
Our philosophy:
Stable networks, clean signal processing and solutions that technically come
as close as possible to professional carrier in-building systems –
even if this investment is higher than with simple wideband solutions.
