Nokia 473439A.202 FXEF Flexi series base stations

Nokia 473439A.202 FXEF is a three-channel 240W Remote Radio Unit (RRU) operating in the 1800MHz frequency band under the Nokia Flexi series. Specifically designed for Nokia NSN base stations, it supports 3G and 4G networks and serves as a core device ensuring efficient signal transmission of wireless communication base stations. Based on product information circulating in the market, the detailed introduction is as follows:

I. Core Technical Parameters

As a 3-pipe Radio Frequency Module (RFM), this product features a core highlight of 240W power output and is specifically adapted to the 1800MHz frequency band. Widely used in 4G network construction, this frequency band balances signal coverage range and transmission speed, making it well-suited for multi-scenario communication requirements. Although specific interface configurations are not fully disclosed through public channels, as a radio frequency unit of the Nokia Flexi series, it is typically equipped with data transmission interfaces compatible with baseband units, multiple antenna interfaces, and standard power supply interfaces. These configurations enable core functions such as signal conversion, antenna signal interaction, and stable power supply.

II. Compatibility & Adaptation Characteristics

As a dedicated radio frequency device for Nokia NSN base stations, it can seamlessly adapt to core modules such as baseband processing units of Nokia Flexi series base stations. A complete communication link can be established without major adjustments to the existing base station architecture. Meanwhile, as a model under the Nokia 473439A series, it shares universal installation specifications with other accessories in the same series, reducing the adaptation difficulty for operators during equipment replacement and capacity expansion, and improving operational efficiency.

III. Application Scenarios

This device is widely used in 3G and 4G base stations built by Nokia, suitable for the construction of communication base stations in various scenarios such as dense urban areas and suburban regions. In urban areas, it can support high-traffic user communication services and ensure stable, non-latency signals. In suburban scenarios, it can help achieve wide-range signal coverage. Additionally, it is a common spare part in base station operation and maintenance. When the original radio frequency unit of a base station encounters issues such as power attenuation or signal transmission failures, replacing it with this device can quickly restore the base station's communication capability and minimize network downtime.

IV. Product Supply, Packaging & After-Sales Service

Both brand-new and refurbished products are available on the market, with prices varying among different suppliers. Negotiable pricing is also available for some bulk purchase orders. In terms of after-sales service, some suppliers offer a one-year warranty, and all products for sale undergo comprehensive inspections to ensure performance compliance. The product adopts standard export packaging to meet the protection requirements during long-distance transportation, while customized packaging services are also supported. Transportation is usually carried out through international courier channels such as DHL and FedEx. The delivery cycle for small-batch orders is typically 2-4 working days, and the delivery time for large-batch orders can be negotiated.
