Description
What is a 3 dBi 868 MHz SMA Antenna?
The 3 dBi 868 MHz SMA Antenna CTRF-ANTENNA-AP-0868-13197-SMA-W Antenna is an 868MHz Omnidirectional antenna designed 13x197mm size 3 dBi gain SMA rubber duck antenna manufactured by C&T RF Antennas Inc.
The Omni Antenna 3 dBi 868 MHz SMA Antenna White Color Rubber Duck Antenna is very suitable for indoor-outdoor Lora & LoraWan node and gateway applications.
LoRa Gateway Access Point Determinants
The number of nodes accessed by a LoRa gateway depends on the channel resources that the LoRa gateway can provide and the channel resources occupied by a single LoRa terminal.
If the LoRa gateway uses the Semtech standard reference design, the number of channels is fixed at 8 uplink channels and 1 downlink channel. Once the number of physical channels is determined, the channel resources that the LoRa gateway can provide are also determined.
(The number of channels varies by gateway design. AUGTEK gateways can achieve 8 uplinks and 4 downlinks.)
The channel resource occupied by a single LoRa terminal is consistent with the time the terminal occupies the channel, which is also closely related to the packet-sending frequency of the terminal, the number of packets sending bytes, and the spreading factor of the LoRa terminal.
When the packet frequency and the number of packet bytes sent by a LoRa terminal rise, the time that the terminal occupies the channel for sending and receiving increases, and more channel resources are taken up.
When the LoRa terminal uses a larger spreading factor, the signal can travel farther, but at the cost of taking more time to deliver a unit byte of information.
In addition to gateways, we also need to focus on LoRa terminals.
A LoRa terminal is an integral part of a LoRa network and generally consists of devices such as LoRa modules and sensors.
LoRa terminals can be battery-powered and can be remotely located.
Each LoRaWAN protocol-compliant terminal can communicate directly with LoRaWAN-compliant gateways, thus enabling interconnection.
