Search snippet preview: The Ericsson KRC 118 75/1 R2C is an outdoor remote radio unit built for cellular network infrastructure, delivering stable RF performance and simplified integration to cut field deployment and maintenance overhead.

The Ericsson KRC 118 75/1 R2C is a high-performance outdoor remote radio unit (RRU) engineered to support modern mobile communication networks, designed to work seamlessly within Ericsson RBS series base station architectures. As a core radio transceiver component, KRC 118 75/1 R2C converts digital baseband signals into radio frequency outputs and receives uplink signals from user terminals, enabling flexible distributed network coverage across urban and rural sites alike. Network system integrators frequently mount the KRC 118 75/1 R2C directly on tower crossarms or rooftop antenna brackets, eliminating the need for bulky shelter-based radio hardware and shortening RF cable runs to reduce signal attenuation.

This unit stands out as a trusted spare part for operators managing legacy and mid-generation mobile infrastructure. Many telecom asset teams rely on the KRC 118 75/1 R2C to replace end-of-life hardware during incremental network upgrades, avoiding costly full-site overhauls. Its compact, passively cooled aluminium chassis balances power density with environmental resilience, making it suitable for sites with limited mounting space where traditional indoor radio cabinets cannot be installed. While distinct from ABB DO810 and ABB I/O modules used within distributed control system parts, this Ericsson radio unit often shares supply chain workflows with industrial automation spare parts procurement teams sourcing critical hardware for remote site operations, alongside ABB AC 800M control system components for hybrid industrial and telecom edge deployments.

The Ericsson KRC 118 75/1 R2C integrates robust RF amplification, built-in monitoring diagnostics and efficient passive thermal design to minimise field failure risks over long operational cycles. The all-aluminium extruded housing delivers superior heat dissipation without dependence on cooling fans, removing a common point of mechanical failure found in fan-cooled radio hardware. Comprehensive onboard diagnostics continuously track power draw, temperature, RF output levels and link status, allowing network operators to schedule preventive maintenance instead of reacting to unplanned outages.

Modular hardware architecture simplifies field servicing; technicians can swap a faulty KRC 118 75/1 R2C within minimal site access windows without reconfiguring adjacent baseband equipment. Fibre-based CPRI connectivity enables flexible separation between radio and baseband processing, supporting distributed network layouts that optimise coverage planning. Integration with existing Ericsson RBS infrastructure is straightforward, with firmware compatibility aligned to standard network management platforms. Although designed for telecom infrastructure, the procurement workflows for this radio spare mirror processes used to source ABB I/O modules and ABB AC 800M hardware for industrial sites, where fast availability of validated spare parts directly limits operational downtime. Compared with older RRU generations, the KRC 118 75/1 R2C offers improved power efficiency, lowering long-term site energy expenditure for operators running large fleets of remote radio hardware.

The KRC 118 75/1 R2C serves as a foundational radio element for macro and micro cellular mobile network deployments across diverse operating environments. Mobile network operators deploy the unit for urban macro tower sites, suburban coverage expansion, and rural remote sites where mains power stability and rugged environmental tolerance are critical. Oil & gas remote field sites, mining operations and large-scale water treatment facilities often deploy this Ericsson RRU to build private cellular connectivity for site communications, pairing alongside distributed control system parts and industrial automation spare parts to support unified site monitoring infrastructure.

Brownfield network upgrades represent one of the biggest use cases for the KRC 118 75/1 R2C. Operators rely on this unit to replace ageing radio hardware without rebuilding existing tower structures, drastically cutting civil engineering costs and site downtime. It is also widely used for highway corridor coverage, smart city infrastructure and campus-wide private mobile networks. Unlike indoor radio solutions, the IP55-rated enclosure removes the requirement for climate-controlled equipment shelters, which is invaluable for temporary construction site communications and remote wind farm installations where building permanent shelters is economically unviable.

Before installing the KRC 118 75/1 R2C, field engineers must verify the mounting structure meets the specified static load requirements and confirm adequate clearance around the heat sink to preserve passive cooling performance. Proper low-resistance earth bonding is mandatory for surge protection, and all fibre and RF cabling must be fitted with waterproof connectors to maintain the unit’s IP55 ingress rating. Site planning should account for cable bend radius limits on CPRI optical leads to avoid irreversible fibre damage during tower installation.

Routine maintenance for the KRC 118 75/1 R2C prioritises visual inspection of connector seals, heat sink surface debris and mounting bolt tension every six to twelve months. Operators should regularly retrieve internal event logs via the network management system to track thermal fluctuations and intermittent link faults, supporting data-driven preventive maintenance. Back up active unit firmware prior to replacement or site reconfiguration to speed up commissioning of spare hardware. If persistent error codes appear following cable integrity checks, full unit replacement is recommended, as field repair of internal RF circuitry is not supported by Ericsson specifications.

Chengdu Sunshine Xi He Electrical Equipment Co., LTD provides a one-year warranty and eligible free replacement service for the Ericsson KRC 118 75/1 R2C, separate from the original OEM manufacturer warranty. Customers may initiate warranty claims via official sales communication channels, including email and WhatsApp support lines. Every unit undergoes complete pre-shipment functional testing before dispatch, and our team can supply matching datasheet documentation and serial-number trace verification upon request. The warranty covers confirmed manufacturing and transport defects detected under standard operating conditions; damage caused by improper installation, lightning surges, unapproved firmware modifications or harsh environmental overexposure falls outside warranty coverage. Should failure occur within the warranty term, our technical team supports remote troubleshooting and expedited spare part delivery to minimise network site outage duration.
