Certainly! In May 2024, Rakuten Mobile is making significant strides in deploying its mobile network using the “Platinum Band” in Japan. Here are the key details:
Platinum Band Allocation: The 700 MHz band, also known as the “platinum band,” was allocated by the Ministry of Internal Affairs and Communications on October 23, 20231. This band has unique properties, allowing it to maintain a strong signal even in the presence of obstacles like buildings or indoors.
Deployment and Technology: Rakuten Mobile will deploy base stations using mobile network radios developed by Nokia Solutions & Networks G.K. in the 700 MHz platinum band. These Nokia mobile network radios are small, lightweight, and energy-efficient. Leveraging its expertise in building the world’s first fully virtualized, cloud-native mobile network compatible with Open RAN, Rakuten Mobile aims to promptly start operating base stations in this band. By using a next-generation Distributed Unit (DU) developed by its subsidiary Rakuten Symphony, Rakuten Mobile can easily deploy the radio in its virtualized, Open RAN network. The newly deployed antennas compatible with both the 1.7 GHz band and the 700 MHz band will coexist alongside existing 1.7 GHz radios, allowing for prompt operation through software updates.
Benefits and Customer Satisfaction: Rakuten Mobile aims to realize a high-quality mobile network by optimally combining the allocated 700 MHz platinum band with its existing 4G and 5G frequency bands and roaming. The deployment will start in urban areas with high user volume and traffic. Rakuten Symphony will collaborate with Nokia to provide these radios to customers in select markets worldwide.
In summary, Rakuten Mobile’s deployment of the platinum band aims to enhance network capacity, improve user experience (especially indoors), and provide cost-effective services across Japan. |
