Full Benefits of Nokia AHDA PN 474739A

Enhanced Coverage in Band 8: Specifically designed to operate on Band 8 (typically 900 MHz), providing excellent wide-area coverage and strong in-building penetration. This is crucial for extending network reach, especially in rural or suburban areas.
Improved Uplink Performance: With 4 receivers (4R), the RRH offers superior uplink sensitivity. This means the base station can effectively receive signals from mobile devices even at the cell edge, leading to better voice quality and data rates for users further away from the site.
Efficient Downlink Performance: The 2 transmitters (2T) with a 120W output power provide a robust downlink signal, ensuring good data speeds and service quality for connected users within the cell.
Cost-Effective Coverage Solution: Band 8 operation often requires fewer cell sites to cover a large area compared to higher frequency bands. This can lead to lower deployment and operational costs for mobile operators.
Part of the Modular AirScale System: As an AirScale Radio Remote Head (RRH), it benefits from the modularity and flexibility of Nokia’s AirScale platform. This allows for easy integration with other AirScale components and future network upgrades.
Energy Efficiency: Nokia’s AirScale products are generally designed with energy efficiency in mind, helping operators reduce their power consumption and environmental footprint.
Compact and Lightweight Design: RRHs are typically designed to be relatively compact and lightweight for easier installation on towers, rooftops, and other locations. This simplifies logistics and reduces installation time and costs.
Support for Multiple Radio Technologies: While primarily for LTE on Band 8, AirScale RRHs often support software upgrades to accommodate future radio technologies, ensuring a degree of future-proofing.
Improved Network Reliability: Distributed architecture with RRHs can enhance overall network resilience. If one RRH experiences an issue, other parts of the network can continue to operate.
Facilitates Network Densification: While providing wide-area coverage, RRHs can also be part of a densification strategy, especially when combined with other frequency bands and cell layers.
