In general, however, we could summarise them as follows:<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Indoor vs Outdoor Use<\/strong> &#8211; Are there many walls or floors in between LoRa devices? What material are they made of?<\/li>\n<\/ul>\n\n\n\n<div style=\"height:1px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Environmental Topography<\/strong> &#8211; Are there mountains or buildings that may interfere with sending or receiving signals?<\/li>\n<\/ul>\n\n\n\n<div style=\"height:1px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Device Interference<\/strong> &#8211; Are there many devices transmitting simultaneously in a small area?<\/li>\n<\/ul>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>LoRa uses sub-Gigahertz radio waves, so they <strong>may pass through some obstructions<\/strong> based on the material they are made of. In other cases, however, those waves will be absorbed or reflected before they reach their intended recipient. Thus, using LoRa in a crowded urban environment may yield you around 2 to 3 km of coverage, compared to about 5 to 7km in rural areas.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>As a general rule, <strong>elevating LoRa devices<\/strong> by placing them on rooftops or higher altitudes will help to improve their transmission range! Other factors, such as &#8211; you guessed it &#8211; <strong>antenna properties<\/strong> can also significantly impact transmission range!<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<div style=\"height:1px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>LoRa Antenna &#8211; What does it do?<\/strong><\/h2>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>For any kind of wireless transmission, LoRa included, there is a transmitter and a receiver. When Device A wishes to communicate with Device B, it will convert the data it wants to send into a radio wave, which the transmitter then emits outwards. The receiver on Device B then receives this radio wave and demodulates it into data that an on-board computer can understand.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><a href=\"https:\/\/www.seeedstudio.com\/Grove-LoRa-E5-STM32WLE5JC-p-4867.html\"><img decoding=\"async\" src=\"https:\/\/lh3.googleusercontent.com\/M160TuW1IbcZQ-lyPb8x1vt2kWreEuFgsmxA2HHf7FX7QGAMQbr842UExL0Ia5_Ia0UK8KmlsyDJJ2KwARrIeeswjtlVmdiwdrNtGMqFJ1NZSwslEenzG1YRgCQgLvQuBEThd8Iw\" alt=\"\" width=\"600\"\/><\/a><\/figure><\/div>\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>A LoRa antenna works closely with the transmitter and the receiver during this process of transmission and reception. In transmission, the transmitter supplies an electrical signal to the antenna, which then emits the signal as radio waves. During reception, on the other hand, an antenna intercepts some power from a radio wave, which is amplified by the receiver.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>While antennas do not create radio energy, they play a <strong>critical role in diverting, directing or concentrating<\/strong> radio wave transmission in a particular direction. In doing so, they can <strong>significantly improve both transmission range and quality<\/strong>, which just might be the boost you need for your LR network! In fact, this directional feature is an extremely important property of antennas &#8211; known as antenna gain!<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Antenna Gain<\/strong> measures the degree of directivity of the antenna\u2019s radiation pattern:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Omnidirectional antennas are designed to transmit and receive radio waves in all horizontal directions equally, whereas;<\/li>\n\n\n\n<li>Directional antennas direct radio waves in a specific direction more than others.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Thus, antennas that have high gain will enable you to achieve longer range and better signal quality in LR communication, but must be aimed specifically in the direction of the receiving antenna. Although low-gain antennas have shorter range, it is less important to be concerned with the direction of the antenna, making it easier to build mesh networks. As a result, your choice of antenna will largely depend on the specific LR communication scenario that you have in mind.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Seeed\u2019s <\/strong><a href=\"https:\/\/www.seeedstudio.com\/Lora-Fiberglass-Antenna-860-930MHz-5dBi-600mm-p-4927.html\"><strong>LoRa Fiberglass Antenna<\/strong><\/a><\/h2>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>If you&#8217;re looking for a LoRa antenna to enhance your LoRa communication systems, you should definitely consider Seeed&#8217;s LoRa Fiberglass Antennas, which have been <strong>specifically designed<\/strong> for use with LoRa radio bandwidths (860MHz &#8211; 930MHz).

Since the material itself does not conduct electricity, fiberglass antennas still have a conductive element included within the antenna to transmit the radio signals. For example, in the case of Seeed\u2019s LR Fiberglass Antenna, that conductive element is copper.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Where a fiberglass antenna truly shines is the enhancements to build quality as a result of the fiberglass material. Fiberglass has extremely high tensile strength, making it resistant to bending and breaking. Additionally, it has high vibration resistance, thermal insulation, electrical insulation, chemical resistance, water non-observant (does not absorb water) and is UV radiation insensitive, which makes it <strong>extremely suitable for operating in harsh outdoor conditions<\/strong>.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>For this reason, fiberglass antennas are often used over traditional steel antennas for outdoor applications like moving trucks, since the rigidity of the material allows the antenna to stay upright even at highway speeds! This also allows the antennas to be mounted on the outside of such vehicles to reduce any losses in transmission range or quality.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<div style=\"height:1px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Long Range Applications with LoRa <\/strong><\/h2>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>LR excels in long-range transmissions and is already being used in many industries to achieve IoT applications in numerous industries.
