On May 3, US satellite communications provider DISH Network officially announced that it will use Samsung’s 5G O-RAN virtualized radio access network (vRAN) and radio unit (RU) equipment. Among them, the RU will support massive MIMO, and DISH’s frequency division duplex (FDD) and time division duplex (TDD) modes.
It is reported that DISH Network will soon launch 5G network services based on O-RAN architecture. John Swieringa, COO of DISH Network, said that Samsung’s software and hardware solutions will provide multi-directional assistance for DISH Network’s expansion in the 5G network field. An indispensable part of field expansion, Samsung’s innovations in vRAN and O-RAN technologies can help DISH Network provide consumers and enterprises with open and interoperable 5G cloud services.
Besides, threeStar will also provide 5G terminal equipment for DISH Network. Currently, DISH Network is using the Samsung Galaxy S22 to test 5G network services, and DISH Network plans to continue to use Samsung mobile phones as a test platform throughout the network deployment process.
In fact, Samsung is not the exclusive supplier of DISH vRAN. It is reported that in addition to Samsung, DISH Network has cooperated with Intel as early as 2020, and adopts Intel Xeon scalable processors, Ethernet 800 network cards, vRAN accelerator ACC100 and related software services.
According to public information, O-RAN, or Open Radio Access Network, is a concept of interoperability and standardization based on RAN elements, including the unification of white-box hardware and open-source software elements for different vendors. interconnection standard. The O-RAN architecture integrates a modular base station software stack on off-the-shelf hardware, allowing baseband and radio unit components from discrete vendors to operate seamlessly together.
O-RAN underscores the streamlined 5G RAN performance goals through the common attributes of efficiency, intelligence and versatility. An open RAN deployed at the network edge will benefit 5G applications such as autonomous vehicles and IoT, effectively support network slicing use cases, and enable secure and efficient over-the-air firmware upgrades, among others.
