In LoRa applications or using Helium hotspots, the following situation often occurs: Helium hotspots cannot receive other hotspot information, or data sent through terminal nodes cannot be transmitted to the LoRaWAN server, resulting in very low coverage of Helium hotspots. Therefore, we need to use an external antenna to change this situation!
Why do I need an external/outdoor antenna?
This is not difficult to understand with the help of an external antenna, because Helium hotspots mainly rely on interaction with other hotspots to achieve coverage. As we know Helium hotspots include radio communication systems, like mobile phones or two-way radios. Therefore, only the signal is strong enough to receive more data. Simply put, it needs to receive the RF of other Helium hotspots in order to increase the coverage of the hotspots. Therefore, the key point to improve the coverage of Helium hotspot is to enhance the signal. At this time, we need to use an LoRa antenna outdoor.
However, the use of an external antenna does not mean that we can install an antenna, but we have to choose a "good antenna" based on the real-time situation and make reasonable use of it to better receive signals and expand the range of hot spots. read more
Before, we introduced what is a LoRaWAN gateway, the composition of the LoRaWAN gateway, and its working principle.
After understanding this theoretical knowledge, today I will help you to choose a LoRaWAN gateway correctly?Generally speaking, there are two points to consider when choosing a LoRaWAN gateway.
First, Whether the functional features of this gateway meet your needs, and second, what are the main deployment scenarios of this product and how to use it.This article takes the LoRaWAN gateway of the RAK series as an example and analyzes the power consumption, number of channels, antenna, range and other aspects, so that everyone can quickly choose the correct and suitable gateway.
For example: suitable for indoor and outdoor or for personal development and business.Read full article here - https://wp.me/p82TdK-4Q
