VeriSilicon and Innobase introduce the second-gen Yunbao series modem IP, featuring 5G RedCap/4G LTE dual-mode support.
VeriSilicon, a leading provider of comprehensive wireless communication solutions, has launched the Yunbao 2 modem IP, a second-generation dual-mode 5G NR RedCap and 4G LTE modem designed for cost-sensitive and power-efficient Internet of Things (IoT) and mobile device segments.
Overview of Yunbao 2
The Yunbao 2 is a dual-mode 5G NR RedCap and 4G LTE modem IP, targeting applications in wearables, industrial IoT, smart home, augmented reality/virtual reality devices, and other battery-powered or low-cost mobile devices that benefit from reduced complexity and power. The technology node for the Yunbao 2 typically synthesizes for advanced low-power processes, with the exact node depending on customer implementation.
Area
Yunbao 2 is optimized to minimize silicon footprint, significantly smaller than full-featured 5G modems. While exact silicon area figures depend on foundry and specific configuration, typical RedCap modems from similar IP providers range between 1.5 mm² to 3 mm² in advanced nodes like 7nm or 12nm. The simpler architecture for RedCap devices helps in reducing logic and memory, leading to smaller area and cost.
Power Consumption
Yunbao 2 is engineered to meet the stringent power envelope for small battery-operated devices. Typical power consumption could be in a range of tens to low hundreds of milliwatts when active, with efficient sleep modes for idle states. Power reduction techniques include support for Power Saving Mode (PSM), Enhanced DRX (eDRX) from 4G/5G standards, efficient protocol processing, and hardware acceleration for baseband functions.
Transmission Rates / Throughput
The Yunbao 2 supports mid-range throughput suitable for many IoT and wearable use cases rather than peak gigabit-class rates. Peak data rates typically up to a few hundred Mbps can be achieved under RedCap specifications. Support for lower bandwidth channels than full 5G NR reduces complexity, while LTE Cat 4 or Cat 6 equivalent throughput ranges (up to around 300 Mbps downlink) depend on configuration. The modem seamlessly switches between 4G LTE and 5G NR modes to conserve power and extend coverage in less dense 5G areas.
Key 5G Features
The Yunbao 2 modem IP is designed to support 3GPP Release 17 RedCap, targeting reduced complexity devices. Key feature highlights include narrower band bandwidths reducing receiver complexity and power consumption, lower number of antennas, and support for OFDMA-based NR modulation. The modem also supports Standalone and Non-Standalone Modes, advanced modulation schemes, flexible subcarrier spacing and numerology, and uplink and downlink MIMO (though reduced compared to full NR modems).
