Network Virtualization -

Networks have passed the point where they need to evolve to meet the growing demands placed upon them, not only for the insatiable demand for modern services but for an ever-increasing number of connected devices requiring uninterrupted connectivity. Software Defined Networking (SDN) and Network Functions Virtualisation (NFV) have made inroads into the deployment and management of communication networks. They provide an agile and scalable solution to meet changing demands in minutes, which would previously have taken days or weeks to resolve. By taking hardware that can be virtualised and deployed on a common infrastructure with shared networking resources, efficiencies can...

LTE -

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...

Transport Industry -

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...
