The first smartphones with MediaTek’s satellite connectivity are also being launched at MWC, and the company said that more devices would be unveiled in the coming months. MediaTek is also sharing its next-generation 5G New Radio NTN (NR-NTN) technology for the next wave of satellite-enabled devices.
Satellite networks aim to fill gaps in mobile coverage, offering a reliable way for devices to communicate in remote locations. With satellite-enabled smartphones, consumers will be able to stay in touch in situations where there has traditionally been no connectivity; but this technology will also enable users to request assistance in emergency situations.
At present, the biggest market opportunity for 3GPP NTN technology is smartphones, although there is a growing demand for satellite connectivity in IoT applications such as agriculture, forestry, and logistics. The automotive industry is also expected to be a major market for satellite communications technology in the coming years.
“Two-way satellite communications on smartphones and other devices will usher us into a new era of connectivity and open up new possibilities across many different verticals,” said JC Hsu, Corporate Vice President and General Manager of MediaTek’s wireless communications business unit. “Our standalone MT6825 chipsets, which are based on the 3GPP NTN open standard, can be integrated into any flagship smartphone to deliver a seamless satellite connectivity experience.”
MediaTek’s satellite communications portfolio will look to target both IoT-NTN and NR-NTN technology based on the 3GPP 5G specification for Release 17 (R17). IoT-NTN is suitable for messaging since it is designed for low data rate connections, while NR-NTN allows for higher data rates that can support video calls and other applications.
Since satellite networks can currently only support IoT-NTN on a mass scale, the initial wave of satellite-enabled smartphones and other devices powered by MediaTek will be designed for two-way satellite messaging services.
MediaTek is currently working with Bullitt to bring the world’s first commercially available devices with 3GPP NTN technology, utilising the MT6825 chipset to connect to the Bullitt Satellite Connect platform. This includes the Motorola defy 2 and CAT S75 smartphones; and the Motorola defy satellite link, a compact and lightweight Bluetooth accessory that allows Android and iOS devices to connect to the Bullitt
According to Bullitt its Satellite Connect service will provide users with access to two-way satellite messaging, location sharing, and emergency SOS in more places around the world.
The forthcoming NR-NTN chipset from MediaTek will allow devices to support services with higher data rates like navigation and real-time communication.
As satellite networks build capacity for NR-NTN over the coming years, this is expected to open up a range of new consumer, enterprise, and industrial use cases as smartphones, IoT devices, and vehicles can take advantage of reliable connectivity everywhere.
To make it easy for brands to integrate two-way satellite communications into smartphones and other devices, MediaTek’s IoT-NTN solutions are standalone chipsets that can be added to any 4G or 5G device. The chipsets utilise the open 3GPP R17 NTN standard, rather than proprietary solutions. For OEMs, the advantage of the standard is that once a device has been certified for 3GPP R17 IoT-NTN it can be used on any IoT-NTN compliant network.
Additionally, mobile network operators can partner with service providers to offer roaming services or establish their own satellite networks that support the standard.
In addition to the benefits of supporting 3GPP R17 NTN, MediaTek’s MT6825 IoT-NTN chipset has a number of other features. It can connect to Geosynchronous Equatorial Orbit (GEO) constellations, which could be converted into 3GPP NTN compliant network easily and are widely available now on the orbit. To provide a seamless experience, MT6825 allows devices to automatically receive messages from satellites, unlike other solutions that require users to manually check for messages. The chipset has low system requirements, is very power efficient to provide greater battery life, and comes in a highly integrated design that helps accelerate time to market.
