At Carritech, we understand that when you buy used telecom equipment, you want the same reliability and performance as you’d expect from new hardware — but without the new equipment price tag. That’s why every Remote Radio Unit (RRU) we sell goes through a comprehensive refurbishment process. From the moment the units arrive at our facility to the moment they leave for our customers, we ensure they meet our strict standards for quality, cleanliness, and functionality.
Why RRUs Naturally Require More Refurbishment Than Other Units
Remote Radio Units are installed in some of the harshest environments in the telecom network — mounted high on towers, rooftops, or exposed to roadside conditions. Over time, they face constant exposure to rain, dust, wind, extreme temperatures, and in some cases, pollution or salt from coastal air. Unlike indoor telecom equipment that operates in climate-controlled spaces, RRUs endure years of weathering, vibration, and handling during installation and removal. This often results in dirt build-up, faded casings, corrosion on connectors, and cosmetic wear that is much more pronounced than other network hardware. For these reasons, RRUs arriving at our facility usually require more intensive refurbishment to bring them back to a standard that meets both our performance criteria and our customers’ expectations for appearance and reliability.
Arrival and Inspection
When RRUs arrive at our warehouse, they often show signs of heavy use — dirt, dust, paint marks, scuffs, and general wear from their time in the field. Our first step is a full visual inspection, checking for physical damage, missing parts, external contamination (dirt, corrosion, etc.), cosmetic defects, and any obvious signs of operational failure. We log the condition of each unit before beginning any refurbishment work, so we can track the transformation from start to finish.
We also power each of the units on to ensure that the product is viable for sales before refurbishment begins.
Deep Cleaning and Cosmetic Restoration
Appearance matters. Customers buying refurbished RRUs want something that looks as good as it works. We carefully clean each unit, removing dust, dirt, and debris, stickers, labels, and tape residue, paint marks or graffiti, and surface oxidation. If required, we also recondition the casing — polishing, repainting, or replacing outer shells to restore a professional, “like new” appearance.
Final Quality Check
Before an RRU is approved for sale, it passes a final quality inspection to confirm no visible defects, all required components are present, and the unit meets Carritech’s quality and performance standards. Only then is it carefully packaged and prepared for dispatch.
Packaging & Shipping
All of our RRU units are packaged within made-to-measure boxes, meaning we reduce the need for excess padding materials that damage the environment. All units are then securely palletised read for safe and secure shipping to our customers.
External Testing
When our customers require us to provide full test reports for the units, we send the RRUs off-site to our external laboratory where they are fully tested. Each unit has its own test report produced which will show all the key checks that have been carried out during the testing process.
