Microwave Transmission Engineering

Data transmission networks spanning across continents are forming the backbone of our information exchanges. They're used to vehicle and route data streams between the communicating parties. The OSI (Open System Interconnection) physical layer recommendation calls, in general, for a wireline (electrical or optical) or wireless (radio signal) transmission medium. The latter realized with microwave radio technology.

Since the early days of telecommunications, researchers and engineers have been weighing the pros and cons of the deployment of point-to-point microwave transmission versus the traditional wireline connectivity and later on fiber-optics. Possibly the strongest argument of the cons side supporters is the lesser reliability of the microwave transmission due to the propagation of microwave radio signals being adversely impacted by external factors such as bad weather conditions or changes in the atmospheric characteristics. However, as the microwave radio transmission may only be a small part of the complex end-to-end communication chain, its reliability contribution to the overall network reliability could be of negligible proportions.

The decision to rollout a MWTN (Microwave Transmission Network) may be of crucial strategical importance to non-incumbent network operators. Short turnover cycles, quasi independence from the infrastructure monopoly operators, flexible and expandable network architecture are just a few of many value plays offered by the MWTN solution. Thorough engineering and technical feasibilities studies on the initial MWTN rollout could give a clear picture on a number of financial and project related metrics. With the help of state-of-the-art MWTN planning tools, the network architecture could be aligned in a way to accommodate multiple layers of wireless access technologies as well as to guarantee enough room for future capacity growth and network expansion.

Wise Noble Limited will assist you in the completion of the following microwave transmission engineering tasks:

• MWTN rollout - also known as the initial infrastructure setup of the microwave transmission network. The main goal here would be to setup the data transport networks in a way to assure RAN connectivity, to guarantee a nominal transmission bandwidth and minimize bottlenecks. Along with the usual microwave link planning and engineering tasks we follow a strategical deployment approach revolving around meeting the end-to-end wireless network reliability targets and the evolution towards an all-IP environment. In addition, our solution will account for multi layer traffic shaping, short and long term prediction of behavioral trends, risk assessment and impact of spectrum shortages, just to name a few.
• MWTN optimization - or the follow up phase after the MWTN rollout is completed. The rapid growth in the number of MWTN elements during rollout naturally leads to a number of undesired side effects. Relying on a pool of live network KPIs (Key Performance Indicators), RAN KPIs cross-referencing, an elaborated optimization plan is established addressing performance laggards. Key component in the MWTN optimization plan is the implementation of solution milestones each addressing a specific engineering activity. This approach is necessary in order to minimize the impact on live network services and exercise strict control over costs.
• MWTN upgrade - driven by shorter depreciation cycles, increased computing capabilities and reduced power consumption of the hardware, migration to SRAN and all-IP transmission, wireless network operators around the world have been rushing to modernize their infrastructure by swapping or upgrading MWTN elements on a massive scale. As data networks around the globe leverage on a fixed set of date transmission technologies, global market players will not hesitate to frequently switch vendors to gain competitive advantages or simply to lower their OPEX. Carefully defined cross-platform mapping of a number of functional MWTN parameters will not only smoothen the vendor transition but will also guarantee the transmission network KPIs.
• MWTN audit - recently gaining on popularity among wireless network operators worldwide as more and more of MWTN rollout, -optimization and -upgrade activities are entrusted to third party contractors. The short project turnover cycles make it almost impossible to achieve high implementation quality standards. An independent professional review and overall assessment of MWTN KPIs and services will contribute to the instant benefit for the involved parties and ensure the transmission network viability in the long run.
