What is a Lora gateway and what does it do? LoRa gateways use different frequency extension factors and different frequency extension factors, and can therefore theoretically demodulate multiple frequency extension factors in the same channel. Gateways and web servers are connected via standard IP, and endpoints communicate with one or more gateways via a single hop.

What is a Lora gateway and what does it do?
LoRa gateways use different frequency extension factors and different frequency extension
factors, and can therefore theoretically demodulate multiple frequency extension factors in the
same channel. Gateways and web servers are connected via standard IP, and endpoints
communicate with one or more gateways via a single hop.
1. What is a LoRa gateway?
A LoRa gateway is located at the core of a LoRa star network and is the information bridge
between the terminal and the server (Server), and is the transceiver of multiple channels.
LoRa gateways are sometimes called LoRa base stations or LoRa concentrators, which have
different definitions but are actually the same meaning.
LoRa gateways apply different spreading factors, two orthogonal sets of different spreading
factors, and are therefore theoretically able to 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, and all the terminal communications are double communications, in addition to the system
upgrade software remote control upgrade, etc.
2. What is a LoRa gateway characteristic?
(1) What is a LoRa gateway classification?
The current gateway types and definitions are different.
For example, according to the different application scenarios, can be divided into the indoor
gateway and outdoor gateway;

According to the communication mode, it can be divided into the full-duplex gateway and
half-duplex gateway;
At this stage, the definition is not the same and the types of gateways are not the same. The
international LoRa alliance released the specification technology of wireless network connection -
LoRaWAN according to the LoRa protocol, and the release of this specification technology has
promoted the LoRa technology to carry out large-scale networking solutions. At this stage, there
are also several companies in China promoting the development trend of LoRaWAN technology.
(2) What is a LoRa gateway capacity?
Gateway capacity refers to the ability of the gateway to receive the number of packets in a
certain period of time.
Theoretically, LoRa gateways support the advantages of LoRaWAN's high capacity, flexible
networking, and low cost for large project deployment.
LoRa network can access thousands of nodes, and the number can be flexibly increased or
decreased according to the project demand, with good network scalability.
Low component cost, free communication fee, low overall operation cost, and obvious
advantages in large projects.
Theoretically, a single SX1301 chip has 8 channels and can receive up to 15 million packets per
day in full compliance with LoRaWAN protocol.
If an application sends packets at a frequency of 1 packet/hour, a single SX1301 chip constitutes a
gateway capable of accessing 62,500 end nodes.
Of course, this is only a theoretical value, and the number of terminals accessed by the gateway
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.
3. What is a LoRa gateway access points determinants?
The number of nodes accessed by LoRa gateways depends on the channel resources that LoRa
gateways can provide and the channel resources occupied by a single LoRa terminal.
If the LoRa gateway adopts the Semtech standard reference design and the gateway adopts the
SX1301 chip, 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).
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 frequency, the number of bytes
sent by the terminal, 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.
4. What is a LoRa gateway terminal?
In addition to gateways, we also need to focus on LoRa terminals.

LoRa terminals are the components of a LoRa network and generally consist of devices such as
LoRa modules and sensors. loRa terminals can be battery powered and can be located remotely.
Each LoRaWAN protocol-compliant endpoint can communicate directly with a
LoRaWAN-compliant gateway to enable interconnection.
5. What is a LoRa gateway antenna?
The LoRa & LoraWan antenna gateway antenna includes so many antenna types such as PCB Lora
antenna, Fiberglass Lora antenna, Rubber duck Lora antenna, Magnetic mount Lora antenna, etc.
The LoRa & LoraWan antenna gateway antenna mainly operates in 433 MHz, 868 MHz, 915 MHz,
etc.
