Microwave Video Links
Navtech offer a variety of microwave video links to suit individual applications. Please read the descriptions below to help you decide which of our generic solutions may be tailored to your system needs.
Analogue Links
Analogue links rely on tried and tested technology that has been perfected and proven for many years. Analogue radios are typically cheaper than their Digital companions and generally consume less power. Analogue links are perfect for long range links and short range line of sight applications alike.
Navtech now even offer a diversity receiver for analogue giving your analogue transmitters a new lease of life for those built up areas and particularly work inside buildings.
COFDM Digital Links
Navtech offers a comprehensive range of COFDM-based digital microwave links that enable video and data to be wirelessly transmitted without the limitations of conventional analogue FM links. Multipath picture break-up is effectively eliminated by the use of COFDM which spreads data over 2000 different carrier frequencies contained within 6, 7 or 8MHz channels. Advanced error correction algorithms together with the latest multiple-antenna diversity reception methods provide an extremely high level of transmission robustness and data integrity. These systems enable reliable non ‘line of sight’ links to be achieved by making use of reflected signal paths and with the increased ‘sensitivity’ of the receivers, an increase in range performance of up to four times can be achieved when compared to conventional analogue FM equipment.
