5G Reduced Capability (RedCap), also known as NR-Light, represents a pivotal advancement in 5G technology. Designed as a streamlined version of 5G New Radio (NR), RedCap bridges the gap between high-performance 5G devices and low-power IoT applications. By offering a balanced blend of throughput, battery efficiency, and device simplicity, RedCap is poised to revolutionize industries ranging from healthcare to smart cities. A critical enabler of its success, however, lies in leveraging external antennas like POYNTING’s solutions to optimize reception and power efficiency.
Introduced in 3GPP Release 17, 5G RedCap offers reduced device complexity, making it cost-effective and energy-efficient for IoT applications. It targets use cases that do not require the ultra-high speed and low latency of full-fledged 5G but still benefit from its improved data rates, reliability, and efficiency.
Supporting video surveillance, industrial sensors, and smart manufacturing with reliable wireless connectivity.
Enabling wearable medical devices for remote monitoring and telemedicine.
Powering traffic management systems and environmental monitoring via connected sensors and cameras.
The Role of External Antennas in 5G RedCap Performance
One of the defining characteristics of RedCap devices is their use of simplified antenna configurations—usually a single transmit and receive antenna, although in some cases, 2x2 MIMO can be employed to increase performance. While this reduces complexity and cost, it can result in suboptimal signal strength in challenging environments. External antennas, such as those offered by POYNTING, are critical for addressing these challenges.
External antennas are designed to capture and amplify signals over a wider range of frequencies. POYNTING antennas, support ultrawideband frequency ranges, ensuring compatibility with 5GRedCap frequency bands and delivering superior connectivity, especially in areas with weak or fluctuating network signals.
With peak data rates of up to 150 Mbps (downlink) and 50 Mbps (uplink), RedCap relies on consistent signal quality to deliver its performance promises. Our external antennas and MIMO options amplify signals and minimize disruptions, ensuring steady throughput.
One of RedCap’s key advantages is its power efficiency. External antennas reduce the energy required by the device to maintain a stable connection, further extending battery life—a critical factor for applications like wearables and industrial sensors, especially those that are battery powered.
POYNTING’s wide range of antenna solutions makes them ideal for diverse RedCap applications. These include wearable devices, smart grids, video surveillance, smart-city applications, traffic management systems and environmental sensors.
POYNTING offers a variety of antennas tailored to meet the unique demands of 5GRedCap applications. Key features include:
As industries transition from LTE Cat 1/4 to 5G RedCap, the demand for affordable and efficient solutions will grow. RedCap’s ability to deliver up to 80% cost savings compared to full 5G, coupled with its reduced energy consumption, makes it an attractive choice for IoT. However, achieving these benefits depends on robust connectivity, which external antennas help ensure.
5G RedCap is set to transform IoT with its cost-efficient and energy-saving capabilities. Yet, its true potential can only be unlocked by addressing its inherent limitations in signal strength and power efficiency. POYNTING’s innovative antennas play a critical role in enhancing 5GRedCap performance, ensuring reliable connectivity, and maximizing battery life across applications like smart cities, healthcare, and industrial IoT. As 5GRedCap adoption accelerates, the synergy between advanced 5G technology and high-performance external antennas will redefine what’s possible in connected solutions.
