Movandi Demonstrates 5G mmWave Connectivity for Cellular Vehicle-to-Everything Communications
May 24, 2021
Movandi, a provider of 5G millimeter wave (mmWave) technology, announced a successful demonstration of mmWave repeaters, delivering 5G cellular vehicle-to-everything (C-V2X) communications for the next generation of connected cars.
Per the company, a Movandi BeamXR powered mmWave repeater installed inside a car enabled greater than 10x performance gains with an average throughput of 1.5 gigabits per second (Gbps) on the Verizon 5G Ultra Wideband network. Test results showed a 25X throughput improvement of a typical 4G LTE service and was conducted on behalf of an industry partner. Watch the video demo as Movandi drives in high-density service areas in San Jose, California, as a typical truck or vehicle would be used.
According to the company, the 5G mmWave spectrum unlocks an order of better performance through much higher data rates and lower latency than can be achieved by the sub-6 GHz spectrum. This performance can enable the low latency and high throughput needed to deliver the mobile connectivity and services required by sensor-laden connected cars, which generate terabytes of data for cloud-based AI systems and predictive algorithms to enhance safety and collision avoidance systems.
As the industry transitions from 4G to 5G, however, some service providers view sub-6 GHz technology as the only feasible 5G option for mobile connectivity in cars. One assumption is higher-speed mmWave technology is too difficult to implement in fast-moving cars where steel and glass materials pose barriers to mmWave signal penetration. The short range and lower data rates experienced by users of 5G mmWave-enabled handsets while on the road illustrate this challenge.
According to Gartner, the attach rate of 5G interfaces in embedded automotive telematics will increase from 0 percent in 2019 to 51 percent by 2029. The automotive market will drive 5G adoption for the Internet of Things (IoT), reaching almost 180 million connections in connected cars by 2029.
Movandi has demonstrated that its BeamXR mmWave powered repeaters integrated in vehicles can solve these challenges, enabling continuous ultra-wideband connections in urban areas with 5G access points spaced approximately 1,000 meters apart. Also, per the company, today’s typical 5G coverage areas, next-generation Node B (gNB) base stations are often deployed 500 meters apart. Coverage is also limited to within very close proximity of a gNB, while BeamXR powered mmWave repeaters extend coverage and provide an ideal handoff between gNBs to maintain continuity. By using mmWave repeaters inside cars, 5G connections with 1.5 Gbps data speeds can be achieved with gNBs placed farther apart (1000 meters or more), enabling low costs by reducing the number of gNBs deployed along roadways.
BeamXR powered repeaters are designed to provide seamless 5G ultra-wideband coverage for end users and edge computing systems in infotainment control panels, whether the car is moving or stationary. The repeaters manage tight coordination with the base station and maintain continuous coverage at highway speeds while completing handoffs among gNBs in sub-seconds. A single repeater can support multiple mobile phones or modems inside a car and provide a 5G backhaul to the cloud for autonomous vehicles. According to the company, Movandi repeaters also reduce mobile phone power consumption and minimize mmWave radiation inside the car.
Movandi offers 5G mmWave reference designs, demos, and trial opportunities to help customers reduce development costs and accelerate time to market.
