Lora Indoor Antenna SMA Antenna

Description

What is Lora Indoor Antenna SMA Antenna?

The Lora Indoor Antenna SMA Antenna CTRF-ANTENNA-AP-8593-10110-SMA-B Antenna is an SMA male connector Rubber Duck Antenna Omnidirectional Lora antenna with a 2.5dBi gain 10x110mm size Lora indoor antenna manufactured by C&T RF Antennas Inc.

At present, the network layer protocols based on LoRa technology are mainly LoRaWAN, and there are also a small number of non-LoRaWAN protocols, but the communication system networks are all-star network architectures, as well as simplifications and improvements based on them.

It mainly includes the following 3 types.

(1) Point-to-point communication.

One point to one point-to-one-point communication, mostly seen in early LoRa technology, point A initiates, point B receives, can reply or not reply to the confirmation, and the frequency between multiple groups is recommended to be separated, purely using the LoRa modulation sensitivity of high characteristics, currently mainly for specific applications and pilot nature of the project.

The advantage is that it is the simplest, and the disadvantage is that there is no networking.

(2) Star network polling.

One-point-to-multipoint communication, N slave nodes take turns to communicate with the central point, upload from the node, wait for the central point to receive and return the confirmation, then the next node starts uploading again until all N nodes are finished and the cycle is over.

The structure is still essentially point-to-point communication, but with the addition of time-sharing processing, the frequency points between N slave nodes can be separated or reused.

The advantage is the low cost of a single project, the disadvantage is that it is only suitable for applications where the number of slave nodes is not large and the network real-time requirements are not high.

(3) Star network concurrency.

One-point-to-multipoint communication, multiple slave nodes can communicate with the central point at the same time, the slave nodes can randomly report data, and the nodes can automatically take frequency hopping and rate-adaptive technology according to the external environment and channel blockage.

Logically the gateway can receive different rates and combinations of signals with different frequency points, physically the gateway can receive 8, 16, 32, or even more ways of data at the same time, reducing the conflict of a large number of nodes when uplinking.

This reduces the probability of conflicts when a large number of nodes are uplinked. The system has great extensibility and can be built separately and cross-grouped. The LoRa field mainly refers to LoRaWAN technology.
