Licensed microwave links offer exclusivity to frequencies in the 7GHz to 40GHz spectrum. Many of them are also animated. Apart from issues such as Fresnel zone, rain fade, and multipath fading which require proper consideration during the path loss calculation, there are also other factors causing interference such as installing the radios adjacent to other radios which would greatly affect the receiving sensitivity of the radio (like when you try to hear a weak voice when standing beside a big speaker that is playing music). The planning of a link must take into account cost, equipment availability, and Line of sight propagation availability. This figure shows the % of bits of data with errors vs the total number of bits that have been transmitted during a period of time. Microwave Network Design 187 Professional Engineering 6X9 / Microwave Transmission Networks / Lehpamer / 122-2 / Chapter 5 microwave links that do not need to be individually licensed. A Microwave link design methods; frequency planning, link budget, Rain fading, fade margin, outages and availability The required capacity (bandwidth throughput) of a point to point microwave link is a key design parameter. Point to Point links are transparent, acting as an extension of the Ethernet backbone or segment. Others can benefit, too.

On Point To Point Microwave Link Today. Microwave networks provide reliable point-to-point and highly directional communication that maximizes your RF transmission. There are also a few frequency bands that are “license-free” – mainly 2.4GHz, 5GHz and 24GHz. For businesses, a point to point microwave link can be revolutionary. While these license-free bands are in much greater use, professional solutions more depend on utilizing licensed frequencies which would guarantee a free-to-use spectrum greatly improving link reliability. Besides Sir J. C. Bose also developed the world’s first solid state point contact detector working at millimeter wave, However, my search on man-in-the-middle attacks on these networks has returned nothing other than occasional mentions on … Microwave link design is a specific sort of engineering in the broader field of communications. Microwave links transmit data between two pre-defined locations. READ PAPER Because Microwave uses a higher frequency band, the capacity, throughput, and reliability of Microwave networks is well proven and understood to be very efficient throughout the telecommunications industry. Design and implementation of a successful and reliable point to point microwave link requires good theoretical knowledge about RF design and antennas, as well as good deal of practical experience. It is intended to be used in conjunction with the Recommendations that are maintained by Radio-communication Study Group 3 to assist in the design of terrestrial point-to-point links. There are now many computer applications that can accurately predict the line of sight and path loss however a visual survey by an experienced engineer is also necessary. Enquire. The concepts mentioned above are the primary information you can ask an implementer to make sure they have the required knowledge and expertise. – Rapid Deployment longitude of these points are used to design with the link planner software. 5 Key Factors for a Stable Microwave Link.

Atoll Microwave is a state-of-the-art Point-to-Point and Point-to-Multipoint Microwave Link Planning Software. However like any other solution and probably more than many others, establishing a reliable and high-quality microwave point to point link can be quite challenging, and if it is not properly designed and implemented, it can cause major quality issues such as lower throughputs, link instability, and longer than expected latency. Clipping is a handy way to collect important slides you want to go back to later. The quality of a point to point microwave link can be determined by below measurements: This ratio is measured by dB and shows the strength of signal vs the noise level for that frequency channel. This is the actual amount of data that can be transferred per second and is expressed by bits per second – for example a bandwidth throughput of 100 Mbps means about 100 megabits of data can be transferred by the link in every second. RAy is a high-speed point-to-point microwave link, suitable for links in the most challenging conditions.. This parameter is expressed in % and determines for what % of time the link has been established over a certain period of time, usually in a 12 months period. TETRA Radios vs GSM and Wi-Fi – What is the Correct Choice? But this is not possible in lower frequencies and two independent radio links should be installed with sufficient frequency and space diversity.

If you need to connect two networks separated by a public road, for example, you might find that regulations restrict you from running cables above or below the road. 27 Full PDFs related to this paper. WTM 6000 and TRuepoint 6500 trunking microwave radios The clear line of sight, choosing an appropriate frequencies which may be used for a specific distance, and path terrain condition, are just few out of several factors that should be considered in designing. Copyright © 2019 Vizocom Company. The line of sight can be limited by natural or man-made obstacles and also by the earth’s curvature which limits the practical distance of microwave links to 50-60kms (which would call for 100m tower heights and large dish antennas to achieve). Interference and fading is another issue that if not handled correctly, can considerably affect the link reliability. A reliable microwave link should have link availability as good as 99.999%. Microwave Link Design - PTP Transmission 1. To use a frequency, a license should usually be obtained from the legal authorities of the country. The reliability of the link can be greatly increased by applying redundancy. You can change your ad preferences anytime. The power consumption is considered for the purpose of subscriber at the receiving site of microwave link. It allows designing large microwave link networks, according to the ITU standards. As the capacity increases, you would need to design the link for a higher SNR, resulting the need for stronger equipment and antennas. Why Businesses in Iraq Need to Leverage Services for VSAT in Iraq for Robust Communications? Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications.Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy.. a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth. – No ROW Issues The higher the frequency, the higher the available capacity but at the same time, the effective range is lowered and the link would be more susceptible to rain or high humidity. The maximum distance between the locations is depends on the antenna size (gain), frequency band, and link capacity, and can vary from a few meters to several kilometers. Below are 5 key factors you would need to ensure about for having a reliable and stable microwave link: Microwave links range from 2.4GHz to 42GHz spectrum.
