Communication Systems
Next-Generation Wireless Systems with Advanced RF Engineering
Communication systems are evolving rapidly, from 5G networks to emerging 6G technologies and Open RAN architectures. At Plextek, we combine 35+ years of engineering excellence with cutting-edge RF design and signal processing to create communication solutions that deliver superior performance in an increasingly competitive landscape. With our deep technical knowledge in proprietary protocol design and multidisciplinary systems integration, we help you differentiate your products in a market dominated by standard reference platforms.
From directional communications that dramatically increase network capacity to advanced modelling that optimises system performance before deployment, our expertise in RF engineering, antenna design, and protocol development helps businesses achieve competitive advantage through superior technical execution in industries where connectivity and performance are critical.
5G, 6G & O-RAN
In today’s democratised O-RAN landscape where most designs derive from standard reference platforms, differentiation comes through superior RF design, advanced signal processing, and multidisciplinary integration.
Our 35+ year track record in proprietary protocol design positions us to deliver the innovative RF and antenna solutions that enable competitive advantage in this transformed market.
Communication System Modelling
Modelling allows us to try out a wide variety of configurations, test how the system performs under difficult circumstances or evaluate novel techniques.
This can be done much more rapidly and at a lower cost than building an actual test network. It also allows us to try things which may be difficult to achieve or rare in the real world, find out how it scales or evaluate technologies which are not yet available.
Directional Communications
Directional communications represent a paradigm shift in radio communications and offers the potential to significantly increase wireless network capacity and make better use of higher frequencies that are being rolled out as part of 5G new radio.
Using advanced RF design and systems engineering, Plextek develops secure, effective and reliable directional communication solutions that address challenges such as interference and spectrum efficiency.
Protocol Design
Protocols underpin how we interact with each other – how we communicate, share information and provide services.
Humans are flexible enough to adapt them for different circumstances, from a simple request to pass the salt during a meal, to nations exchanging high-level diplomatic notes.
