简要描述：
RRU 4499 B1/B3( KRC 161 787/1) The Ericsson Radio 4499 B1/B3 (Model KRC 161 787/1) is a powerful dual-band Remote Radio Unit (RRU) designed for LTE Band 1 (2100 MHz) and LTE Band 3 (1800 MHz).Part of Ericsson’s latest Radio 4499 Series, this RRU provides high output power, superior coverage, and multi-standard support (GSM, WCDMA, LTE). It enables mobile operators to deploy efficient, compact, and flexible macro cell networks optimized for both capacity and coverage.
The Ericsson Radio 4499 B1/B3 is a dual-band macro radio designed to support LTE Band 1 (2100 MHz) and LTE Band 3 (1800 MHz) simultaneously. It belongs to Ericsson’s Radio 4499 series, offering high power, high performance, and flexibility for multi-band macro cell networks.
It supports multi-technology compatibility (GSM / WCDMA / LTE) and is engineered to deliver excellent coverage, capacity, and spectral efficiency for urban and suburban deployments.
Dual-Band Capability: Simultaneously supports Band 1 + Band 3 (2100 + 1800 MHz) deployment, allowing operators to combine coverage and capacity bands.
4T4R MIMO Architecture: Offers 4 transmit and 4 receive channels per band, enhancing throughput and reliability.
High Output Power: Can deliver up to 4 × 80 W (total) without fan, enabling strong signal reach across both bands.
Multi-Standard Support: Supports GSM, WCDMA, and LTE in each band, facilitating smooth evolution and network integration.
Outdoor Robust Design: Designed for outdoor use, with rugged enclosure, suitable for macro cell site deployment.
Flexible Mounting / Connectivity: Offers fiber connectivity to baseband units and flexible installation options.
Alarm & Interface Support: Includes external alarm inputs, grounding points, field alarms, etc.
