What is the difference between the QUATRA 4000 and the QUATRA 4000i?
There are two variants available for the Cel-Fi QUATRA 4000:
Cel-Fi QUATRA 4000:
- The QUATRA 4000 is FCC Part 20 certified. It supports bands 2,4,5,12,13, 25.
Cel-Fi QUATRA 4000i:
- The QUATRA 4000i is FCC Part 90 certified. It supports bands 2,4,5,12,13, 25, 26, 30, 41, and 71.
Can I use the QUATRA 4000 system outdoors?
Cel-Fi QUATRA 4000 is for indoor use only and it should not be used outdoors.
How does the QUATRA 4000 work?
Cel-Fi QUATRA 4000 is a powerful cellular signal distribution solution. Cel-Fi QUATRA 4000 is fundamentally comprised of a Network Unit (NU) and up to six (6) Coverage Units (per NU). The Network Unit takes the donor input from up to four (4) carrier signal sources. The signal source can be off-air (over-the-air (OTA)) from the macro network, or delivered via a small cell. Each port is carrier specific and can be either off-air or small cell driven.
The NU receives the source signal, digitizes the RF, and distributes it over two Category (Cat5e) cables (per CU) to the CU. The CU converts the digital signal back to RF, boosts it, and transmits from its RF port to provide cellular coverage at the location.
What are the QUATRA 4000 key features?
- Carrier Grade, FCC-certified Smart Signal Booster
- Support for AT&T, Verizon, T-Mobile and Sprint
- Relays two (2) bands per operator, simultaneously
- Independent donor ports for each operator allows for independent antenna optimization
- Single combined (CU) server port enables driving either a serving antenna or passive DAS field
- 100 dB max system gain
- 140MHz total relay bandwidth
- 6 channels x 20MHz
- 2 channels x 10MHz
- Support for up to six (6) CU via Cat5e cable
- N-type RF connectors (donor and server)
- Internal modem for remote management (SIM slot access)
- Up to 100m distance between NU and CU
- QUATRA Range Extender (QRE) extends the NU to CU distance by 100 meters
- 20-22dBm uplink power per operator per band
- 16dBm downlink power per operator per band
Can you combine both donor antenna feeds?
Yes, if the donor signal is coming from the same direction.
What is the USB on the back of the QUATRA 4000 used for?
The USB on the back of the QUATRA 4000 NU is for COMPASS Connection. The USB on the back of the QUATRA 4000 CU is for Nextivity use only.
What is the SFP+ module dock on the NU used for?
This port will be used for future fiber expansion.
Can the QUATRA 4000 LTE modem and LAN Port be connected at the same time?
Yes, the LAN connection has priority over the modem, however the modem may serve as a backup.
How many antennas can I use with a QUATRA 4000 CU?
It all depends on the type of application, we recommend up to four antennas depending on cable losses.
Can I extend the NU to CU cables more than 100 meters?
Yes.
My CU lights are all solid green, but my system is not relaying?
All of the CU lights will turn solid green once the CU starts relaying one channel, give the system some time to start relaying the additional channels.
