868MHz Dipole Antenna SMA Antenna

Description

What is 868MHz Dipole Antenna SMA Antenna?

The 868MHz Dipole Antenna SMA Antenna CTRF-ANTENNA-AP-0868-13197-SMA Antenna is an Omni dipole antenna designed 3 dBi gain 868MHz SMA antenna 13x197mm size plastic rubber duck antenna manufactured by C&T RF Antennas Inc.

The 868MHz Dipole Antenna SMA Antenna is very suitable for indoor-outdoor Lora & LoraWan node and gateway applications.

What is a LoRa gateway?

LoRa gateways are located at the core of a LoRa star network, are the information bridge between the terminal and the server (Server), and are the transceivers of multiple channels.

LoRa gateways apply different spreading factors, two orthogonal sets of different spreading factors, and therefore can theoretically modulate and demodulate several data signals with different spreading factors in the same wireless channel.

The connection between the gateway and the cloud server is carried out according to the standard IP, and the terminal communicates with one or several gateways according to the single hop, all the terminal communications are double communications, in addition to the system upgrade software remote control upgrade, etc.

Features of LoRa gateway

Military-grade LoRa modulation technology is used, which greatly improves the communication distance and communication stability; large single packet, single packet supports up to 197 bytes, adapted to Modbus;

Simple and efficient power supply design, support power adapter or crimping method, support 10~36V power supply; transmitting power up to 5W, all technical indicators reach European industrial standards;

Adopt temperature compensation circuit, frequency stability better than earth 1.5PPM.

Operating temperature range: -40 ℃ ~ +85 ℃, adapt to a variety of harsh working environments, true industrial grade products;

All aluminum alloy shell, compact size, easy installation, good heat dissipation; perfect shielding design, good electromagnetic compatibility, strong anti-interference ability; power reverse protection, over-connection protection, antenna surge protection, and other multi-protection functions, greatly increasing the reliability of the radio;

Powerful software functions, all parameters can be set by programming: such as power, frequency, air rate, address ID, etc.; ultra-low power consumption, the watchdog current is only 23mA (power-saving mode and sleep mode power consumption is even lower);

Built-in watchdog and precise time layout, once the abnormality occurs, the module will automatically restart and can continue to work according to the previous parameter settings.

The capacity of the LoRa gateway

Gateway capacity is the ability of the gateway to receive the number of packets in a given time. Theoretically, a single chip with 8 channels can receive up to 15 million packets per day in full compliance with the LoRaWAN protocol.

The number of gateway access terminals is ultimately related to the number of gateway channels, the frequency of packets sent by terminals, the number of packets sent bytes, and the spreading factor.
