NOKIA AHDB 474257A RRU (Radio
Remote Unit) is a key component in Nokia communication equipment and is mainly
used in the base station part of the wireless communication network. RRU is
usually used together with BBU (Building Baseband Unit, baseband processing unit)
to form the wireless part of the base station. Designed for low power
consumption, reducing operational costs. Easy to install and integrate into
existing network infrastructure. Support
network expansion and upgrades with minimal disruption.
The main functions of RRU include the
sending and receiving, modulation and demodulation of radio frequency signals.
It receives the baseband signal from the BBU, converts it into a radio
frequency signal and transmits it through the antenna; at the same time, it
also receives the radio frequency signal from the antenna, converts it into a
baseband signal and sends it to the BBU. This division of labor and cooperation
makes the base station design more flexible, and the location and number of
RRUs and BBUs can be adjusted as needed.
NOKIA AHDB RRU, as a product of Nokia,
usually has the characteristics of high performance, high reliability and good
compatibility. It may support multiple wireless standards and frequency bands
and can adapt to the needs of different operators and scenarios. At the same
time, as a leader in the communications industry, Nokia's RRU products usually
adopt advanced technology and design to ensure stable network operation and
high-quality services.
