Cellular Coverage Repeaters
2G / 3G / 4G / 5G · multi-band multi-standard · off-air, fibre and BTS-coupled
Multi-band, multi-standard cellular repeaters for 2G, 3G, 4G and 5G networks, in off-air, fibre-coupled, SDR digital and BTS-coupled configurations. Band and standard combinations are configured per project rather than fixed into a model number, because coverage projects vary in band set, channel count and power class.
Exact model numbers, verified parameters and certification status are provided on request. We do not publish cellular model numbers publicly because the band and standard configuration is project-specific.
- Band and standard combinations are project-specific — a fixed model number would misrepresent the configuration you actually need.
- Several configurations are not yet third-party certified, and the certification status differs by frequency band and standard.
- Publishing a model list now would freeze combinations that are still being finalised with carriers.
Generations and bands supported
Band codes follow 3GPP so they match exactly what your carrier and regulator use in correspondence.
- G8 (900 MHz E-GSM)
- G3 (1800 MHz DCS)
- W1 (2100 MHz)
- W8 (900 MHz)
- W5 (850 MHz)
- B1 (2100 MHz)
- B3 (1800 MHz)
- B7 (2600 MHz)
- B8 (900 MHz)
- B28 (700 MHz)
- B20 (800 MHz)
- B41 (2500 MHz TDD)
- B38 (2600 MHz TDD)
- n1 (2100 MHz)
- n3 (1800 MHz)
- n7 (2600 MHz)
- n8 (900 MHz)
- n28 (700 MHz)
- n41 (2500 MHz TDD)
- n78 (3300–3800 MHz C-band)
Multi-standard combinations are written with consecutive generation letters — for example GLN = GSM + LTE + NR. TDD and SDL/SUL variants are quoted separately because they are not the same radio configuration.
Coupling forms and bandwidth types
These are configuration choices rather than separate product families — one platform covers several.
Coupling form
- AOff-air (RF)
- FFibre-coupled (optical)
- DDigital fibre (SDR-based)
- BBTS-coupled
Bandwidth type
- BBand-selective — amplifies the whole band
- CChannel-selective — passes only configured channels
- SSub-band — passes a configurable slice within the band
Channel-selective units with per-channel AGC and squelch are used where the band is congested and full-band amplification would raise the noise floor.
Power tiers — configured per project
Output power is configured per project rather than fixed in the model number, so the same platform serves very different deployment sizes. The tiers below follow the ETSI repeater classification and the 3GPP small-cell ranges.
| Tier | Downlink | ETSI repeater class | 3GPP cell class | Typical use |
|---|---|---|---|---|
| P20 | 20 dBm | Local Area | — | Single room, basement, utility duct |
| P23 | 23 dBm | Local Area | Femto | Home, single-office |
| P27 | 27 dBm | Local Area | Pico | Small building, part of a workshop |
| P30 | 30 dBm | Local Area | Pico | Commercial floor, retail hall |
| P33 | 33 dBm | Local Area / Medium Range | Micro | Whole building, mall, office block (common indoor ceiling in China) |
| P37 | 37 dBm | Medium Range | — | Campus, park, hospital |
| P43 | 43 dBm | Medium Range / Wide Area | — | Wide-area, rural, roadside |
| P46 | 46 dBm | Wide Area | Macro | Large-area coverage, base-station class |
ETSI TS 138 106 caps rated passband output power as: base limit + X, where X = 10 × log(ceil(passband bandwidth / 20 MHz)). More bands means less power per band — quoted power is the total rated power, not per band.
Regulatory power limits by market
Uplink is the constrained direction — a repeater must not raise the phone's transmitted power beyond what the network allows. Limits below are published figures; the operator agreement for your site always governs.

Send the requirement, not the model number
Tell us the bands (by 3GPP code), the generations to support, the coupling form, the power class and the coverage target. If your project requires certification in a particular market, say so — we will tell you what is realistic rather than quoting a lead time we cannot meet.
Full datasheets, verified parameters and certificate status are issued on request.
