Design of a brand new digital microwave radio for high capacity data transmission (super-pdh)

Latvia, sweden and lithuania will cooperate to develop a new super-pdh digital hierarchy radio for the 24ghz - unlicensed - frequency band. Use of alternative solutions and technologies will allow for designing this product with target markets in eastern europe and africa.

Over the past five years, the telecommunications sector has rapidly changed. Initially it was characterised by a dramatic decline in capital investment in telecommunications and wireless data communications sectors, while in the last two years, the industry's leading corporate consolidation has been aggravated by competition in the market and brought to a sharp decrease in product prices. Project partners over the years have strengthened its reputation as a direct provider of microwave solutions (instead of a complex product supplier, which includes, for example, communications tower construction), and it has been able to establish a stable range of clients worldwide. The project’s main participant in recent years has been looking for ways to maintain its radio engineering tradition of uniting with the opportunity to implement innovative microwave solutions. In this way, project partners have decided to take on the design of brand new super-PDH (Plesiochronous Digital Hierarchy) radio equipment for data transmission in the unlicensed radio frequency of 24 GHz (Giga Hertz). With the new challenges, project partners plan to carry out research work in a new market segment - 24 GHz band - the frequency unlicensed in the greater part of the world and used for radio astronomy and radio-locator data. To develop these products, project partners need to follow specific standards for these frequencies - EIRP (equivalent isotropically radiated power). It has a fixed transmitter power flow, which can be transmitted through the air, while down in small output. The radio communication systems, equivalent isotropically radiated power (EIRP) - the power of the theoretical isotropic antenna (that evenly distributes power in all directions), are ensuring the highest power density and the maximum antenna gain direction. EIRP can take into account losses in transmission lines and online, which also includes a gain antenna. EIRP is often stated in terms of decibels, dBi (decibels isotropic emitting radiation with the same antenna-in-power). EIRP allows comparisons between different emissions, without regard to their type, size or form. By knowing the real EIRP and antenna gain, we can learn the real power of the broadcast and the radiated field strength. This standard defines a maximum transmitter power flow, which may be transmitting on the air (up to 20 dBi), while also providing for its low power output, which in turn means that the maximum distance between the devices is a few kilometres, and thus is assumed that, depending on the country’s legal situation, the solution could be used for small power amplifiers. The solution could be a small duplex shift which is technically difficult to create. Project partners based on their experience are planning to implement a new research and development project to create such a product mainly for export to Africa where there has been great interest in such a microwave solution. All three project partners have taken part in new and specific radio production. The first innovative quality for the product is its unique ability to provide up to 100 Mbps of data transmission based on traditional technologies. The other important project tasks would be the introduction of super-PDH significant improvements due to project partners’ adapted chip, and the ability to provide data transmission frequency where the client is using a chip, and most of the target markets are not substantially used. The project partners have shared their competencies within scientific research, design and product development and will mainly use their knowledge and resources for development of this high capacity microwave radio solution. RIGA TECHNICAL UNIVERSITY will participate and support research activities for both commercial project partners. It will be responsible for evaluation of research made by the main participant and will participate in testing new product components to find the most suitable materials. The main participant SAF TEHNIKA JSC is responsible for research into carrying out technical solutions for new equipment design. The main participant will also provide the construction of the first prototype for microwave radio equipment. FORTEK IT will participate in the definition phase by developing a technical task and specifications according to demand in the market. After prototype construction, FORTEK IT will test this equipment in LITHUANIA. The project consists of a definition phase and technical construction phase. The partners are going to implement the project during 2009, as stated in the Protocol of Intentions. The international cooperation for LATVIA and LITHUANIA has several aims - FORTEK IT will have a possibility to provide products in the market earlier than other manufacturers; RIGA TECHNICAL UNIVERSITY will apply results of their fundamental research on a commercial scale; SAF TEHNIKA will get common knowledge for construction of products that are in high demand in the market.
