Nokia AYGE 475647A: Multi-GNSS Dual-Band Antenna for 4G/5G AirScale Synchronization

Introduction

Precise time and phase synchronization is the backbone of reliable 4G LTE and 5G NR mobile networks. To maintain stable signal transmission, low-latency communication, and seamless cross-site handover, base stations require high-accuracy GNSS timing references in diverse and harsh outdoor environments. The Nokia AYGE 475647A is a professional telecom-grade integrated GNSS receiver and active antenna, specially engineered for the Nokia AirScale base station ecosystem. It is a core synchronization component for new network deployment, equipment upgrading, and field replacement of faulty timing devices.

Different from traditional split-type antenna and receiver solutions, the Nokia AYGE 475647A integrates GNSS receiving circuits and antenna modules into one compact, weatherproof dome housing. Adopting L1/L5 dual-band reception and supporting multiple global satellite constellations, it effectively eliminates ionospheric interference, resists signal attenuation and shielding, and delivers ultra-stable timing and positioning performance for cellular base stations. The upgraded variant AYGE 475647A.101 is fully compatible and interchangeable with the standard model for all AirScale application scenarios.

FAQ:

Q1: What is the main purpose of the Nokia AYGE 475647A?
A1: It is a dedicated GNSS synchronization device for Nokia AirScale base stations. Its core function is to provide high-precision time, frequency and phase synchronization reference signals for 4G and 5G cellular networks, ensuring network stability, low latency and seamless user handover between different base stations.

Q2: What GNSS satellite systems does this antenna support?

A2: The device supports four mainstream global navigation satellite systems, including GPS, GLONASS, Galileo and BeiDou. The L1/L5 dual-band design effectively resists environmental interference, improves positioning and timing accuracy, and maintains stable signal reception even in urban canyon scenarios with partial signal shielding.

Q3: Is AYGE 475647A.101 different from the standard AYGE 475647A model?

A3: There is no functional difference between the two models. The .101 suffix represents a minor hardware revision and optimization. The two versions are fully interchangeable in AirScale base station deployment, compatible with all matching host equipment and installation accessories.

Q4: Can this device be used for non-Nokia base station equipment?

A4: The Nokia AYGE 475647A is customized and optimized for the Nokia AirScale ecosystem with exclusive interface and protocol adaptation. It cannot be directly used for base stations of other brands without professional interface modification and program adaptation.

Q5: Is the Nokia AYGE 475647A suitable for long-term outdoor operation?

A5: Yes. It adopts a professional outdoor waterproof and dustproof dome structure, with excellent weather resistance and environmental adaptability. It can operate stably for a long time in complex outdoor telecom site environments, resisting extreme weather such as high and low temperature, strong wind, rain and snow erosion.
