The company also said it would release new technology for adaptive active noise cancellation, "to deliver an improved user experience for earbuds with integrated ANC".
In a statement, Qualcomm said: "The new Snapdragon 4-series is designed to be truly global, supporting the rapid proliferation of 5G, which is already available with more than 80 commercial networks in more than 35 countries across Oceania/Australia, Africa, Asia, Europe, North America and South America."
In June, Qualcomm released a 5G capable 6-series chip, and said that it would help to reduce prices for devices that supported the new technology. Devices with this chip are expected to be available before the end of the year.
“The Snapdragon 4-series 5G Mobile Platform is designed to exceed expectations for the mass-market segment by bringing an assortment of predominately high- and mid-tier features to a broader audience. It will deliver on the promise of making 5G accessible to all smartphone users.”
Devices based on the 4-series 5G chip are expected to be available in the first quarter of 2021.
Motorola president Sergio Buniac said: “Motorola strives to bring smarter technology to all. With the extension of Qualcomm Technologies’ 5G Mobile Platform into the Snapdragon 4-series, we are positioned to deliver a more complete portfolio of 5G devices to our consumers, emphasizing our leadership in the 5G space."
OPPO founder and chief executive Tony Chen said: “OPPO and Qualcomm Technologies have closely collaborated on the expansion of 5G. We are very happy that Qualcomm Technologies is scaling 5G technology to the Snapdragon 4-series.
"We will continue to collaborate with Qualcomm Technologies to drive the large-scale adoption of 5G around the world.”
Lei Jun, founder, chairman and chief executive of Xiaomi, said, “2020 marks the year of 5G proliferation. In scaling the deployment of 5G, we have introduced several 5G smartphones powered by Snapdragon 8-series and 7-series 5G mobile platforms.
"Today, it is exciting to see Qualcomm Technologies expand 5G to the Snapdragon 4-series, accelerating 5G global commercialisation. Xiaomi will become one of the world’s first OEMs to introduce a 5G smartphone powered by the Snapdragon 4-series 5G mobile platform. This is another step forward in our long-standing collaboration with Qualcomm Technologies.”
About its new ANC technology, Qualcomm said: "Effective ANC performance is usually dependent on creating a tight seal once the earbud is placed into the ear which can cause discomfort and be difficult to achieve.
"Qualcomm Adaptive ANC is designed to reduce the dependency on forming a tight seal so a user doesn’t need to push or twist the earbud into the ear. Variation in fit can also occur depending on user activity, for example as a user is running, walking, or even moving their head.
"Qualcomm Adaptive ANC is designed to dynamically adapt performance in real-time according to the tightness of fit and the level of leak-through no matter how or where the earbuds are being used."
