Why radio communication?

Dependence on satellites or fixed infrastructure presents various operational vulnerabilities, which could make it challenging to achieve effective strategic communication. Radio communication offers a unique solution that is self-owned, self-controlled and less vulnerable to jamming and destruction.

Traditional radio communication uses high frequency (HF), very high frequency (VHF) or ultra-high frequency (UHF) radio waves to transmit information from one radio to another. The transmissions in these frequency bands vary greatly in range and quality, making each band appropriate for use in different situations.

VHF and UHF radios operate well within a relatively short range and typically give clear transmissions. However, line-of-sight is required as the signal paths can be hindered by terranean objects and vegetation. This includes buildings, mountains and forests. Furthermore, VHF and UHF communication are not suitable for use in deserts, tundra or grasslands where the distances are too great.

HF communication, on the other hand, is a staple for use in remote areas and was the primary means of long-range communication before the launch of satellites. HF radio waves reflect off the ionosphere, a series of ionised layers high above the atmosphere, to provide beyond-line-of-sight communication. This form of propagation enables HF transmissions to be sent and received over hundreds or even thousands of kilometres, making it particularly well-suited for maritime applications. Although inherent low data rates and potential eavesdropping pushed this technology to the backseat, HF is making a comeback with an infusion of new digital technology. Wideband HF, digital signal processing and improved link security offer a reliable, cost-effective alternative to satellite communications and allow users to rediscover the benefits that HF radio communication has to offer.

Product Divisions

RapidM serves various clients in the global market, including system integrators, radio makers and resellers who, in turn, serve navies, militaries and governments, as well as industrial, civil and commercial users around the world. We supply our clients with an extensive range of products and services, divided into four distinct product segments below.

Naval and strategic operations require interoperability among a diverse set of radio communication systems. This enables allied nations to operate in synergy and successfully manage complex missions. RapidM knows the ropes and can assist system integrators in navigating their way through this dynamic domain with our continually expanding range of maritime communication products. Our high-end data modems, ALE controllers and ARQ protocol units offer exceptional levels of performance. Our products also fully comply with emerging and relevant industry standards, including ISO, IEC, CE and interoperability standards such as MIL-STD-188-110B and 110C; MIL-STD-188-141B, 141C and 141D; and STANAG 4538, 4539, 4539/TDMA, 5066, and 4691.
Secure, reliable and robust communication is crucial for the success of operations in volatile tactical and joint situations. To command, control, and support forces, our continually expanding product range provides secure digital voice, position, and messaging services, even between diverse and mixed-vendor radio equipment. Our products are highly secure, keeping data and information protected to meet the demands of evolving operational situations. Leading-edge waveforms and exceptional product design further provide our rugged products with unmatched reliability and well-integrated services, enabling everyone to stay in the know.
Because the safety of your citizens is a priority, our governmental and security communication products empower your agencies, police, first responders and paramilitary forces to do their best work and keep your people protected. These products provide cost-effective proprietary HF data communications, as well as standards-based solutions for 2G ALE andMIL-STD-188-110B. The RA range of products improves communications reliability and offers secure long-range and beyond-line-of-sight voice, position and data services over existing HF and VHF radio transceivers.
Radio makers are faced with ever-expanding functional and performance requirements when developing HF and V/UHF radios. To meet these changing demands, RapidM’s range of embeddable modules provide next-generation digital capabilities to new and existing designs at minimal integration effort and lower overall project cost. As a further aspect of RapidM’s commitment to our clients, we provide various associated services, including integration support and product adaptation. These services are supported by our strong assurance of supply, giving leading radio makers the ability to manage the supply of their resources and reliably fulfil demand.
