KYOCERA | April 19, 2022
Kyocera Corporation has developed a Transmissive Metasurface technology that can redirect wireless network signals in a specific direction to improve the coverage area and performance of 5G and eventually 6G networks. The Transmissive Metasurface will help deliver high-frequency millimeter-wave 5G and 6G to places where communication is impossible due to obstacles, expanding service areas beyond the capability of conventional Reflective Metasurface technologies used today.
The 28 GHz band used in 5G networks, and the higher frequency band being studied for 6G, have a high degree of rectilinear propagation. Signals often cannot reach locations where a direct line of sight to the base station is obstructed. Reflective Metasurface technology offers a very limited ability to change the direction of a signal to reach these areas. To solve this issue and expand performance, Kyocera developed a new Transmissive Metasurface technology that can redirect radio waves at smaller angles to extend targeted network coverage.
Features: Transmissive Metasurface Technology
1) Kyocera expands the direction in which radio signals can be redirected
Radio waves striking a conventional Reflective Metasurface device can be redirected at a wide angle, but not at narrow angles beyond the metasurface. Kyocera’s new Transmissive Metasurface technology is able to bend at narrow angles in order to avoid obstacles that may block transmission, expanding 5G and eventually 6G coverage even further. For example, a large building may block 5G network transmission, but Kyocera’s Transmissive Metasurface device can redirect the signal downward to reach smaller buildings behind and below for better coverage.
2) Proprietary Flexible Size Development
The area in which a Transmissive Metasurface can deliver signals is proportional to the size of the metasurface itself. Conventional technologies have been unable to develop a Transmissive Metasurface of sufficient size for practical use, but Kyocera can design any size using its proprietary technology, allowing greater flexibility. This makes it possible to install metasurfaces in more places, such as a home patio or apartment balcony.
5G Test Results
Kyocera tested its new Transmissive Metasurface using a 28 GHz band local 5G environment at its Kagoshima Kokubu Plant (Kagoshima Prefecture, Japan). Terminals were installed at two locations: Location A (reception power: -97 dBm), where signal strength is weak due to walls obstructing line-of-sight to the base station; and Location B (reception power: -67 dBm), where signal strength is high due to an unobstructed line-of-sight to the base station through a window. When a Transmissive Metasurface was installed outside the window at Location A, signal strength was -68 dBm, about the same as at Location B with its clear line-of-sight.
Kyocera is developing a Transparent Transmissive Metasurface that is more landscape-friendly and incorporates technological improvements to focus radio waves in specific locations and improve signal strength further. Additionally, the Company is developing a Reconfigurable Intelligent Surface (RIS)* that can create a smart signal environment to change the signal direction adaptively depending on the devices in use.
Kyocera Corporation the parent and global headquarters of the Kyocera Group, was founded in 1959 as a producer of fine ceramics (also known as “advanced ceramics”). By combining these engineered materials with metals and integrating them with other technologies, Kyocera has become a leading supplier of industrial and automotive components, semiconductor packages, electronic devices, smart energy systems, printers, copiers, and mobile phones. During the year ended March 31, 2021, the company’s consolidated sales revenue totaled 1.5 trillion yen (approx. US$13.8 billion). Kyocera is ranked #603 on Forbes magazine’s 2021 “Global 2000” list of the world’s largest publicly traded companies, and has appeared on The Wall Street Journal’s list of “The World’s 100 Most Sustainably Managed Companies.”

Ekinops | February 09, 2022
Ekinops (Euronext Paris - FR0011466069 – EKI), a leading supplier of optical transport systems and access network solutions, has delivered its first Ekinops360 ETSc, a new compact Optical Transport Networking (OTN) platform that enables a new Transport-as-a-Service (TaaS) model for service providers.The optical wavelength services market is expected to nearly double by 2028 with small and medium size enterprises (SMEs) expected to provide a majority of that growth with sub-10G services making up over half of a $7 billion market*.
OTN is the enabling technology to make this happen because it allows service providers to partition the capacity of a single optical carrier and sell it in sub-rate increments rather than requiring a customer to purchase an entire wavelength. OTN also allows the service provider to increase revenue by offering a premium, customized service level agreement (SLA) using secure, dedicated bandwidth and performance monitoring for each individual sub-rate service.
The Ekinops ETSc leverages this field proven technology using the latest advances in network processor chipsets to enable a new 'Transport-as-a-Service' (TaaS) model for service providers with the performance requirements that today's high capacity, high value services demand. OTN makes TaaS possible by allowing it to match the amount of bandwidth used to the client data rate for any size service from Gigabit Ethernet (1.25 Gbps) to 400GbE with dedicated resources end-to-end and rapid provisioning capability.
The Ekinops360 ETSc provides full OTN switch capability with scalability from 100Gbps to 6 Tbps to address the requirements of any network node from access to the core. As small as 1RU and with low power consumption, it can even be used as customer premises equipment (CPE) for Layer 1 services. Highly agile and flexible, the ETSc can be used for both new and existing infrastructure deployments as well as for service delivery. Initial interest came from a new North American Tier 1 customer and the ETSc is currently undergoing full field validation and integration into an open, multi-vendor SDN-controlled environment. The new OTN platform can also be managed by Celestis NMS, Ekinops' converged network management system that provides a single tool for end-to-end management of both Ekinops360 OTN and WDM networks.
"We designed the ETSc to be a flexible scalable, future-proof system using state-of-the-art technologies that can operate in open network environments, It will allow Ekinops to address new customers and applications that we couldn't with our WDM portfolio alone helping Ekinops achieve its stated goal of tripling transport revenue by the end of 2024."
-Vincent Munière, Group Chief Technology Officer and Vice President of Research & Development at Ekinops
