Teltonika TRB255 LTE Gateway
TRB255 is an industrial LTE (Cat M1) / NB-IoT / EGPRS Gateway equipped with GNSS receiver, Ethernet port, durable 16 pin connector block. It has all essential features for an industry in one package: secure power connector, I/O ports, serial communication, fast and reliable internet connection. TRB255 can be used to integrate modern and legacy industrial equipment in one solution and with a wide range of software features such as LTE Cat M1, NB-IoT, SMS control, Firewall, open VPN, IPSec, Remote Management System (RMS), and FOTA support. With backwards compatibility to EGPRS (2G) network, legacy industrial devices can be upgraded for extended use and support of LTE Cat M1 and NB-IoT ensures long lifecycle.

| Signal Improvement Solutions (Cellular) |
| Teltonika TRB255 LTE Gateway includes an antenna port to attach external cellular antennas. See below for different options for high gain and high performance indoor and outdoor antennas to improve the signal strength and indoor coverage. Additionally, see below for RF bidirectional amplifiers/ distributed antenna systems/ repeaters/ small cells to further improve indoor coverage without directly attaching pigtail/ cable the device. |

Because the Teltonika TRB255 LTE Gateway device has an external antenna port you could use the high gain external antenna kits above to boost your signal. However, if your outdoor signal is very weak, or you require a very long cable run to get from the outdoor antenna to the device (long runs lead to large signal loss) consider using an RF bidirectional amplifier/ repeater suitable for the supported bands and cellular operator to boost your indoor coverage: LTE Antenna Boosters/ RF Bidirectional Amplifiers/ Repeaters/ Relays |

STEP 1: Determine what frequency bands your operator uses here, then click on the frequency band link to view the best ranked cellular antennas compatible with the frequency band that both your device and your cellular operator supports. Your Teltonika TRB255 LTE Gateway operates on these frequency bands: Cellular, LTE Band 1, LTE Band 2, LTE Band 3, LTE Band 4, LTE Band 5, LTE Band 8, LTE Band 12, LTE Band 13, LTE Band 18, LTE Band 19, LTE Band 20, LTE Band 28, LTE Band 39.
STEP 2: Determine the cable length you need from the outdoor antenna to the Teltonika TRB255 LTE Gateway and configure your length here (select N-Male on both ends)
STEP 3: Determine if you need a lightning protection device. If you do, you will need a jumper cable.
STEP 4: Order the pigtail for your modem below:
STEP 5: If the pigtail's Connector 2 is FME-F you will need an N-Female/FME-F adapter to mate to the N-Male cable in step 2. Alternatively, select an N-Male/FME-M cable in step 2 above (more expensive and less re-usable) to avoid requiring this adapter.
