rakuten 4g

Last updated on 

Rakuten Mobile is a Japanese telecommunications company that has been working on deploying a 4G (fourth-generation) wireless network. However, please note that developments in the field of telecommunications may have occurred since then, and it's advisable to check for the latest information.

In a general technical sense, 4G technology refers to the fourth generation of mobile network technology, succeeding 3G (third generation). Here are some key technical aspects related to 4G networks:

  1. LTE (Long-Term Evolution) Technology:
    • 4G networks are primarily based on LTE technology, which provides high-speed wireless communication.
    • LTE allows for faster data transfer rates, lower latency, and improved spectral efficiency compared to previous generations.
  2. Frequency Bands:
    • 4G networks operate on various frequency bands, including both lower-frequency bands (sub-1 GHz) for better coverage and higher-frequency bands (1-6 GHz) for higher data transfer rates in specific areas.
    • The use of multiple frequency bands allows for a balance between coverage and capacity.
  3. Multiple Antenna Technologies:
    • MIMO (Multiple Input, Multiple Output) technology is commonly used in 4G networks. It involves the use of multiple antennas for both transmitting and receiving data, which improves data rates and network performance.
    • Beamforming, a technique that focuses the signal in specific directions, is often used to enhance signal strength and quality.
  4. IP-Based Architecture:
    • 4G networks are based on an IP (Internet Protocol) architecture, enabling seamless integration with the internet and supporting a wide range of multimedia services.
    • IP-based networks facilitate a more efficient use of resources and enable a smoother transition to future technologies.
  5. Packet-Switched Networks:
    • 4G networks utilize packet-switched networks, where data is divided into packets and transmitted separately. This contrasts with circuit-switched networks, offering more efficient use of network resources.
  6. Backhaul Infrastructure:
    • The backhaul infrastructure of a 4G network is crucial for connecting cell sites to the core network. Fiber-optic cables are commonly used for high-capacity and low-latency backhaul connections.

Regarding Rakuten Mobile's specific implementation of 4G, the company has been known for its innovative approach, including the use of virtualized and cloud-native network architectures. Rakuten has aimed to build a cost-effective and efficient network infrastructure to provide high-quality wireless services.

For the most accurate and up-to-date information, I recommend checking the latest technical documentation or announcements from Rakuten Mobile or relevant telecommunication authorities in Japan.
