Taiwanese chipmaker MediaTek, in collaboration with Verizon and Ericsson, has recently completed data and voice (VoNR) sessions over Verizon’s 5G network using Ericsson’s new reduced capability (RedCap) software and MediaTek’s RedCap testing platform.

This breakthrough technology is expected to pave the way for the development of lower-complexity and lower-cost New Radio (NR) devices, such as consumer wearables, fitness trackers, and mobile medical devices.

Verizon states that this innovation will not only benefit devices that require voice connections, but also enhance the performance of Internet of Things (IoT) solutions, including video surveillance, industrial sensors, and smart grids, on the Verizon 5G network.

These devices typically transmit and receive smaller amounts of data compared to smartphones and wireless routers, and the efficient paths demonstrated by the new software and light chipset could lead to the creation of smaller, lighter, and more energy-efficient devices with longer battery lives.

During the trials, both data and voice sessions were conducted using 5G over the C-band TDD spectrum and the 850 Mhz FDD spectrum. Verizon highlights that the introduction of NR RedCap devices will expand the 5G ecosystem, offering similar data rates to 4G LTE-enabled devices but with improved latency, device energy efficiency, and spectrum efficiency. Furthermore, this technology has the potential to support advanced 5G NR features, such as enhanced positioning and network slicing.

The 5G spectrum encompasses a wide range of bands designed for specific communication purposes. Low-band 5G enables long-distance communication, while high band is ideal for short-distance communication. MediaTek and Verizon’s successful trials focused on the higher bands within the 5G NR spectrum, operating between 410 MHz-7125 MHz or 24250 MHz-52600 MHz.
