Alcatel-Lucent RRH1900-4X45 Remote Radio Head

Description

Product Introduction & Engineering Value

The Alcatel-Lucent RRH1900-4X45 is an outdoor remote radio head for 1900 MHz PCS cellular infrastructure. Its 4×45 W configuration places the RF electronics close to the antenna system while the associated baseband equipment handles the digital processing. Alcatel-Lucent documentation identifies the unit as a 1900 MHz PCS RRH with four 45 W RF channels and a 65 MHz reference.

This is an exact-match replacement item. The RF band, channel configuration, baseband pairing, optical interface, power arrangement, software compatibility, and site configuration all need to agree. Field records also identify 109787622 as an associated Alcatel-Lucent part number for this RRH.

Technical Specifications

The Alcatel-Lucent technical manual gives physical dimensions of approximately 637 × 272 × 282 mm for the 1900 MHz 4×45 W RRH.

Identification note

Do not confuse the RRH1900-4X45 with the Alcatel-Lucent RRH1900 4×40 W variant. The manufacturer’s documentation lists these as separate 1900 MHz PCS configurations, with the 4×45 W version specified for a 65 MHz configuration.

Field Application & the “Trench” Experience

A radio replacement can look successful right up until the sector is brought back into service.

Consider a site where one RRH1900-4X45 fails. The replacement powers on and the fiber link comes up, but the sector remains unavailable. The engineer then discovers that the replacement was provisioned against the wrong radio configuration, or the RF path and baseband pairing were not checked before the swap.

For this equipment, the correct commissioning sequence matters. Verify the radio model, sector assignment, BBU/RRH relationship, optical connection, DC power, antenna path, alarms, and software compatibility before declaring the replacement successful.

The RRH1900-4X45 is documented in real-world cellular tower inventories alongside other Alcatel-Lucent RRHs, confirming its use as outdoor radio equipment in deployed wireless infrastructure.

Specific application scenarios

• 1900 MHz PCS macro-cell sectors requiring four-channel remote RF transmission.
• Outdoor distributed base-station deployments where the radio head is mounted close to the antenna system.
• Legacy Alcatel-Lucent cellular network maintenance where an exact RRH replacement is required to restore an existing sector.

Transparency SOP: QA & Testing

For New Surplus RRH1900-4X45, a proper inspection should include:

1. Identity verification
Confirm and, where applicable, associated P/N 109787622.

2. Mechanical inspection
Inspect the enclosure, mounting points, RF connectors, fiber interfaces, power connectors, and weather seals.

3. Environmental inspection
Look for corrosion, water ingress, damaged seals, oxidation, or evidence of prolonged outdoor exposure.

4. Power test
Apply the correct DC supply using an approved test environment and verify normal startup.

5. Optical/network test
Verify the communication link to compatible baseband equipment where test equipment permits.

6. RF verification
Check the four RF chains using suitable calibrated telecom test equipment.

7. Alarm verification
Check for hardware, temperature, power, optical, and RF-related alarms.

8. Documentation
Record the serial number, hardware revision, test equipment used, and actual test results.

For an outdoor RRH, physical condition matters. A clean-looking enclosure does not prove that the RF or power sections are healthy.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Confusing 4×40 W and 4×45 W versions

Alcatel-Lucent documentation identifies separate 1900 MHz 4×40 W and 1900 MHz 4×45 W configurations. Do not approve a substitution based only on “RRH1900.”

⚠️ Trap #2 — Forgetting the baseband relationship

An RRH is part of a larger radio architecture. Before replacement, document the BBU configuration, sector assignment, optical connection, and software release.

PRO TIP: Photograph the RRH label and every connected cable before disconnecting the unit. Record which fiber and RF connections belong to each sector.

⚠️ Trap #3 — Treating outdoor condition as cosmetic

Check for water intrusion, corrosion, damaged seals, and connector contamination. These issues can produce intermittent faults that are difficult to reproduce on a bench.

⚠️ Trap #4 — Accepting “power tested” as RF tested

A radio that boots is not necessarily capable of transmitting correctly on all four RF paths. Ask specifically whether the supplier tested the RF chains.

Dynamic FAQ

What is Alcatel-Lucent ?

It is a 1900 MHz PCS Remote Radio Head configured for four 45 W RF channels with a 65 MHz reference bandwidth.

What is the associated Alcatel-Lucent part number?

Available parts references associate 109787622 the .

Is this a 4T4R radio?

The 4X45 designation and Alcatel-Lucent documentation identify four 45 W RF channels. The exact MIMO/sector configuration should still be confirmed against the site’s radio architecture rather than inferred solely from the model name.

Can another 1900 MHz RRH replace it?

Not automatically. Verify RF power configuration, bandwidth, baseband compatibility, software/firmware, optical interface, antenna configuration, and site provisioning.

What should I verify before purchasing a New Surplus unit?

Confirm the complete model, associated part number, hardware revision, serial number, RF configuration, physical condition, and whether the unit was actually RF-tested. Request photographs of the actual RRH.

Can an outdoor RRH be tested without installing it on a tower?

Basic electrical and communications testing can be performed with appropriate laboratory or telecom test equipment. Full RF validation requires suitable calibrated equipment and an appropriate test configuration.

Does New Surplus include the site’s radio configuration?

No. The physical RRH and the network’s provisioning/configuration are separate. Do not assume that a replacement contains the configuration of the failed field unit.

What warranty should I request?

Specify the warranty period, New Surplus condition, serial-number traceability, RF test scope, optical/communication test scope, and return terms. For this RRH, I would specifically ask whether all four RF channels were function-tested, rather than accepting only a power-on test.
