Permanent Link to Qualcomm launches 3 dual-frequency + NavIC smartphone modules
New modules enable entertainment, advanced connectivity features and next-generation artificial intelligence
Qualcomm Technologies has launched three new mobile platforms — the Qualcomm Snapdragon 720G, 662 and 460 — to enable enhanced user experiences across connectivity, gaming and entertainment.
The new mobile platforms support dual-frequency (L1 and L5) GNSS to improve location positioning accuracy and robustness. The system-on-chip solutions also support the Indian NavIC (Navigation with Indian Constellation).
Seven constellations. For the first time supported on mobile, the Qualcomm Location Suite now supports up to seven satellite constellations concurrently, including the use of all of NavIC’s operating satellites for more accurate location performance, faster time-to-first-fix (TTFF) position acquisition, and improved robustness of location-based services.
“ISRO is satisfied with the efforts of Qualcomm Technologies Inc. towards incorporating NavIC and we urge OEMs to leverage it for future handset launches in India,” said K. Sivan, chairman, ISRO. “The availability of NavIC across multiple mobile platforms will help enhance the geolocation capabilities of smartphones in the region and bring the benefits of this indigenous solution to Indian consumers for their day-to-day use.”
The new modules also enable fast 4G connectivity speeds, deliver key Wi-Fi 6 features and integrated Bluetooth 5.1 with advanced audio via the Qualcomm FastConnect 6-series subsystems.
Artificial Intelligence. Designed to deliver new and improved AI user experiences across photography, voice assistants and virtually always-on scenarios for increased contextual awareness, the new platforms also feature the Qualcomm AI Engine and Qualcomm Sensing Hub.
“While we see a fast adoption of 5G across geographies globally, we do recognize the phenomenal boost that 4G has given towards enabling broadband connectivity for Indian consumers. 4G will continue to remain a focus area for Qualcomm Technologies for regions like India, where it will stay a key technology for connectivity,” said Rajen Vagadia, vice president and president, Qualcomm India Pvt. Ltd. “Our goal is to enable our partners to continue creating solutions that offer seamless connectivity access and exceptional mobile experiences, that consumers can count on.”
“Today’s smartphone users want fast, seamless connectivity, advanced features and long-lasting battery life,” said Kedar Kondap, vice president, product management, Qualcomm Technologies, Inc. “This expansion of our 4G lineup enables our partners to offer sophisticated solutions that meet global demand and enable a remarkable gaming experience across multiple tiers and price segments.”
