Overview

8862AS1800 is Part of ZTE’s ZXSDR R8862A remote radio (RRU) platform. It supports GSM / UMTS / LTE (multi-mode) operation depending on configuration. Two transmit channels (2T) and four receive channels (4R) is typical among R8862A variants. The “S1800” designation implies this variant is optimized for the 1800 MHz band (LTE band 3 / GSM 1800) in many markets.

Electrical / Power

• The module likely operates on –48 V DC (common for RRUs) (some supplier listings for 8862AS1800 indicate this).

• Power consumption will depend on mode, load, and configuration; typical values for R8862A family (other bands) are on the order of hundreds of Watts under load.

• gross weight ~13 kg for the 8862AS1800 unit (packaged) in some product catalogs.

Mechanical / Environmental

• The R8862A family typically uses a compact, weather-hardened outdoor enclosure.

• Operating temperature range in related R8862A documentation: –40 °C to +55 °C (for many band variants)

• Protection: outdoor grade (likely IP65 or similar) typical for RRUs of this class.

Interfaces & Connectivity

• Optical / digital interface (CPRI or equivalent) for connection to the Baseband Unit (BBU). Standard R8862 supports CPRI links (various rates).

• RF ports: antenna interface ports for transmit and receive (2T / 4R) in 1800 MHz band.

• Control interface: management, status, alarm ports (Ethernet or proprietary) typical for RRU architecture (as per R8862 family).

Performance

• Bandwidth support: the R8862A series supports multiple LTE channel bandwidths (1.4, 3, 5, 10, 15, 20 MHz) in many variants.

• Output power: For other R8862A variants, the transmit power per channel can reach in the order of 60 W per TX chain in some modes. (Thus total 2×60 W, depending on region, cooling, configuration).

• Noise figure, isolation, linearity, etc., are not found in public sources for the S1800 variant.
