Telecom equipment repairing in Bangladesh — what actually fails
Bangladesh sites run mixed Huawei, ZTE, Ericsson, Nokia and microwave radios in heat, humidity, unstable AC and lightning. The usual failures are PA/LNA damage, VSWR trips, DC-DC collapse, clock/sync loss, IF/modem faults on IDU/ODU pairs, water in ODU housings, and corroded connectors — not “software only”. A Dhaka engineer who can open the board, meter rails, and replace RF/power components saves the swap-out cost of a new RRU or microwave ODU.
HovorTech is a Dhaka service and repair center: intake, ESD bench, component-level diagnosis, soak test, then return with notes. We do not sell grey-market cloned radios as “repaired”.
RRU Repair and telecom RRU Repair
RRU Repair (Radio Remote Unit / Remote Radio Head) is the most searched telecom hardware job in Dhaka. Typical RRU work:
- No power / dead DC input / blown protection and DC-DC stages
- TX low power, PA overheat, VSWR alarm, RX sensitivity drop
- CPRI/eCPRI optical link down, SFP cage or PHY faults
- Over-temperature, fan and heat-sink path, moisture ingress
- Board-level PA, LNA, pre-driver, bias and control MCU repair
Bring the RRU model, serial, alarm screenshot and whether the mate BBU still sees the radio. HovorTech telecom RRU Repair covers 2G/3G/4G radios used on Bangladeshi BTS sites.
Telecom BBU Repair
The BBU (Baseband Unit) is the indoor brain: baseband processing, clock, transmission and RRU control. Telecom BBU Repair at HovorTech includes:
- Main control / baseband board not booting
- Clock, GPS/1588 sync and backhaul card faults
- Power module, fan tray and backplane issues
- Optical/electrical port failure toward RRU or transmission
- Component-level repair of PMICs, FPGAs support circuits, PHY and memory where feasible
BBU software reload is not a substitute for a burnt power rail. We separate hardware fault from configuration so commissioning teams are not sent to a dead chassis.
Telecom IDU Repair and IDO / indoor microwave unit
Microwave indoor units are IDU (Indoor Unit). Many search boxes type IDO — same class of indoor modem/IF equipment paired with an ODU. Telecom IDU Repair covers:
- No traffic, high BER, modem unlock, IF cable fault
- IDU not seeing ODU (power on IF, telemetry, mute)
- Ethernet/E1/STM tributary ports down
- PSU, fan and control-board component repair
Send the IDU/IDO model with the matching ODU type and a photo of LEDs or NMS alarms.
Telecom ODU Repair and Microwave service and repair
The ODU (Outdoor Unit) sits on the tower or rooftop with the antenna. Water, lightning and VSWR kill ODUs. Telecom ODU Repair and full Microwave service and repair:
- ODU dead, no 48 V / IF DC, lightning FET and gas-tube damage
- TX mute, low RSL, high MSE, unlock after rain
- Gasket, waveguide, O-ring and connector corrosion
- PA/LNA and synthesizer board-level repair where parts exist
- IDU+ODU pair test before the unit goes back to site
HovorTech is a Telecom device Service center in Dhaka for licensed and unlicensed microwave, plus related indoor switches that sit behind the IDU.
Old optical power meter repairing
Field teams still use older handheld optical power meters (OPM) and light sources. When the InGaAs detector ages, the ADC drifts or the battery rail dies, readings lie and fiber jobs fail. HovorTech repairs old optical power meters:
- No display, keypad, or charging
- Unstable dBm, offset, or dead wavelength (1310/1490/1550 nm)
- FC/SC adapter, detector window, and connector barrel
- Calibration check after repair (bring a known-good source if you have one)
Brands commonly seen in BD fiber crews: EXFO, Grandway, Deviser, Joinwit, Shinho, local OEM meters. Tell us the model; old does not mean unrepairable.
Fusion splicing machine repairing
A splicing machine (fusion splicer) that will not arc, will not align, or burns electrodes stops OSP and FTTH work. Service includes:
- Arc fail, electrode wear, dirty V-groove and mirrors
- Core/cladding alignment motors, cameras and heaters
- Battery, inverter and high-voltage arc board
- Firmware stuck / boot loop (hardware first, then software)
- Oven, stripper and cleaver related faults when bundled
Fujikura, Sumitomo, INNO, Darkhorse, Signal Fire and similar kits used in Bangladesh can be booked in. Do not ship with loose electrodes in the chamber.
Telecom switch repairing
Telecom switch here means carrier and ISP Ethernet/aggregation switches, industrial PoE, and small OLT/ONU-side switching — not a PABX sales counter. Failures we see:
- No boot, corrupt bootloader vs dead PSU (we separate the two)
- SFP/SFP+ cages, PHY, and one-port-dead boards
- PoE controller and magnetics damage after surge
- Fan, RTC battery and management CPU rails
If the box still boots, bring the config backup. Component level repairing of the PSU and PHY often returns a switch that “only needed a new unit” according to the vendor quote.
SDR software commissioning
SDR in Bangladesh telecom talk covers two jobs, and HovorTech supports both sides of the bench:
- Software Defined Radio (SDR) lab: GNU Radio / USRP-class radios, RF front-end bring-up, driver and firmware load, spectrum checks for training, R&D and custom links.
- SDR BTS / software-defined base station commissioning: radio parameters, RRU-BBU pairing, frequency/PCI/power, VSWR and VSWR-related hardware vs software, and site acceptance after a repaired radio goes back.
Commissioning without hardware repair leaves VSWR and PA faults in place. Repair without commissioning notes sends a unit back that the NOC cannot integrate. We document alarms, versions and test results so your SDR software commissioning team can close the ticket.
Personal telecom design and development
Personal telecom design and development at HovorTech is small-run and custom work — not a factory EMS brochure:
- RF/IF breakout, bias-T, and test jigs for RRU/ODU benches
- Alarm, fan and power-supervisor boards for shelters
- Optical-to-electrical helpers, LED/status panels, and cable adapters
- Schematic-level reverse of a dead board when the OEM file is gone (for repair, not cloning a vendor radio)
- Firmware dump / MCU support circuits when the board is yours to maintain
Share the goal (repair jig, monitoring, training SDR, site gadget), voltage, and enclosure. We design around parts we can actually source in Dhaka.
Component level repairing — the core method
Every item above lands on the same method: component level repairing. That means microscope, hot air, rails, RF path, not “board swap and hope”.
| Layer | What we do |
|---|---|
| Power | DC-DC, hot-swap, surge, fuse, MOSFET, electrolytic and MLCC |
| RF / IF | PA, LNA, filters, bias tees, synthesizers where parts exist |
| Digital | PHY, MCU, clock, memory, FPGA support (not pirate FPGA bitstreams) |
| Optical | SFP cages, drivers, meters, splicer cameras/arc |
| Mechanical | Gaskets, fans, connectors, waveguides, V-grooves |
This is the same Dhaka engineer / Engineer Bangladesh bench used for industrial board repairing — applied to telecom radios and tools.
