The demand for mobile broadband services is putting increased pressure on LTE mobile operators. Simply deploying LTE base stations to provide LTE coverage is only part of the solution. Radio network optimization is widely accepted as a means of improving capacity and performance in a cost-effective manner. The Wray Castle LTE Optimization course enables optimization engineers to identify key parameters which can be tuned to provide peak performance demanded by subscribers. Many optimization engineers will have cut their teeth on GSM and UMTS networks. But LTE is a relatively new technology with its own unique radio characteristics. This training course...

The Wray Castle Microwave Link Planning course is structured as a thorough step-by-step guide through the practical aspects of the link planning process. A series of exercises, students will design and plan a microwave link network to reinforce the learning gained in the theory sessions. Availability and reliability, path profiling and clearance criteria, power budgets, rainfall and multipath fading, diversity techniques, and frequency planning are all the key topics covered. The course focuses on the ITU-R models for calculating rainfall fade depth, the impact of the melting layer, selective fading (signature method), enhancement or “up-fades” and space and frequency diversity improvement. Other...

The Wray Castle Strategy and Technology – Positioning for 5G training course rapidly builds a range of competencies critical to maximising the opportunities being presented by both digital transformation and the adoption of 5G and advanced technology concepts. The 5G initiative provides the focus for the next digital revolution that encompasses connected innovation and the increasing digitalisation of a wide range of industries, as well as advanced connectivity and communications. It provides the foundation for transforming business models and positioning; the customer proposition and focus; and the technologies that underpin that transformation. However, aligning strategic technology choices to take full advantage of...

The Wray Castle GSM-R Engineering Overview is a unique course tailored to those involved in railway networks and GSM-R. GSM-R is the railway enhanced version of GSM - the Global System for Mobile communications. Originally a European initiative promoted by the International Union of Railways (UIC) to provide seamless pan-European radio communications for railway traffic traversing international borders. The UIC collaborated with ETSI (European Telecommunications Standards Institute) to specify a system that has now been adopted worldwide. The Wray Castle course introduces the work of the UIC and ETSI in developing a standards based technology specifically for railway operators. It introduces the...

The term ‘Unified Communications’ describes any communications system, usually a business system, which encompasses a broad range of technologies and applications that have been designed, sold and supported as a single communications platform or as one entity. Unified communications systems generally enable companies to use integrated data, video and voice in one supported product. Unified communication systems typically include the means to integrate real-time or near-real-time unified messaging, collaboration and interactive systems. For example, a single user can access a variety of communication applications such as e-mail, SMS, video, voice and others through a single user mailbox. Additionally, unified communications...
