5g nsa speed

Last updated on 
  1. 5G Network Architecture:
    • 5G NSA is a transitional deployment strategy, where 5G is deployed alongside existing 4G LTE infrastructure. It doesn't have a standalone core network; instead, it relies on the existing 4G infrastructure for certain functions.
  2. Dual Connectivity:
    • NSA uses a concept called dual connectivity, where a device simultaneously connects to both 4G and 5G networks. This allows for faster data transmission as both networks can be utilized concurrently.
  3. LTE Anchor:
    • In 5G NSA, the LTE (Long-Term Evolution) network serves as an anchor for control plane functions. The control plane is responsible for managing signaling and connection setup. The LTE anchor helps in managing the initial connection establishment and other control-related tasks.
  4. Data Transmission:
    • For data transmission, the user plane (actual data transfer) can utilize both 4G and 5G radio interfaces simultaneously. This enables higher data rates and lower latency compared to using either 4G or 5G alone.
  5. Carrier Aggregation:
    • Carrier aggregation is a key technique in 5G NSA. It involves combining multiple carriers (frequency bands) to increase the overall bandwidth available for data transmission. This is achieved by aggregating LTE and NR (New Radio) carriers.
  6. Higher Frequency Bands:
    • 5G introduces higher frequency bands, often referred to as mmWave (millimeter-wave) frequencies. These bands offer higher data rates but have shorter range and may be more susceptible to obstacles. In 5G NSA, these higher frequency bands are used in conjunction with existing LTE bands to enhance overall network capacity and speed.
  7. Massive MIMO (Multiple Input Multiple Output):
    • 5G NSA networks often deploy Massive MIMO technology, which involves using a large number of antennas at base stations to improve spectral efficiency and increase the data throughput. This technology is particularly beneficial in crowded urban environments.
  8. Beamforming:
    • Beamforming is another technique used in 5G to improve signal quality and coverage. It involves focusing the radio signal in specific directions, targeting the user device more precisely. This helps in achieving higher data rates and better connectivity.
  9. Low Latency:
    • 5G NSA aims to provide lower latency compared to previous generations. The use of advanced technologies, such as shorter transmission time intervals and improved signaling procedures, contributes to reduced latency in data transmission.

5G NSA achieves higher speeds through a combination of dual connectivity, carrier aggregation, the use of higher frequency bands, advanced MIMO technology, and other techniques designed to enhance data rates and reduce latency. It leverages the existing 4G infrastructure while introducing new technologies to pave the way for the full-fledged 5G Standalone (SA) deployment in the future.
