Benefits of Nokia AHHB PN 474252A

Excellent Wide-Area Coverage: Operating on the 800 MHz band (Band 20) provides superior propagation characteristics, enabling extensive coverage with fewer cell sites. This is particularly beneficial for rural and suburban deployments.
Improved In-Building Penetration: Lower frequency signals like those in Band 20 penetrate building materials more effectively, leading to better indoor coverage and a more consistent user experience inside homes and offices.
Enhanced Uplink Performance: The 4 receivers (4R) offer excellent uplink sensitivity, allowing the base station to receive weak signals from mobile devices at the cell edge more effectively. This translates to better voice quality and data rates for users farther away from the tower.
Robust Downlink Performance: The 4 transmitters (4T) with a 160W output power ensure a strong and reliable downlink signal, providing good data speeds and service quality to users within the coverage area.
Cost-Effective Rural and Suburban Deployments: The wide coverage provided by Band 20 means fewer cell sites are needed to cover large areas, leading to lower capital expenditure (CAPEX) and operational expenditure (OPEX) for mobile operators in less densely populated regions.
Part of the Modular AirScale System: Being an AirScale RRH, it integrates seamlessly with Nokia’s other AirScale baseband units and software, offering flexibility and scalability for network evolution.
Energy Efficiency: Nokia’s AirScale products are designed with energy efficiency in mind, helping to reduce power consumption and environmental impact.
Compact and Lightweight Design: RRHs are generally designed to be relatively small and light, simplifying transportation, installation, and tower loading requirements.
Support for LTE and Future Technologies: While primarily used for LTE on Band 20, AirScale RRHs often have the capability to be software-upgraded to support future radio access technologies, ensuring a degree of future-proofing for the investment.
Improved Network Reliability: The distributed architecture of RRHs contributes to better overall network resilience. If one RRH experiences an issue, other parts of the network can continue to function.
補完更高頻段 (Complements Higher Frequency Bands): Band 20 can be used as a coverage layer that complements higher frequency bands (used for capacity) in a heterogeneous network deployment, providing a consistent experience across the entire cell.
