Huawei BBU3900, BBU5900 and baseband boards

The baseband unit is where a Huawei site's capacity actually lives, and because it is a chassis populated with plug-in boards rather than a single sealed product, most enquiries are for a specific board rather than a whole BBU. That distinction matters commercially: replacing a failed baseband processing board is a fraction of the cost of a new cabinet, provided you can identify the board and confirm it is supported by your software release. The items listed here cover BBU3900 and BBU5900 chassis alongside the UBBP, WBBP and UMPT board families that populate them.

How to read these part numbers

Huawei board names describe function rather than sequence. `UBBP` is universal baseband processing, `WBBP` is the earlier WCDMA-specific baseband, `UMPT` is universal main processing and transmission — the control and transport board — and `LMPT` is its LTE-only predecessor. The trailing letter and digit indicate generation and variant, so UBBPe6 and UBBPg1 are different capabilities within the same family, and UMPTa2 and UMPTb1 are successive generations. The `03` eight-digit code is the ordering reference; the `WD2D...` string is Huawei's internal configuration code and is the most precise identifier when a model name is ambiguous.

Ordering notes

Specify the board family and the exact generation letter, because capacity differs substantially between variants within one family. Confirm which BBU chassis the board will go into and, critically, your software release — Huawei enforces board and release dependencies, and a newer board in an older release will not commission. Also confirm how many cells and carriers the board must serve, since that determines whether the variant you have identified is adequate. If you are expanding rather than replacing, tell us what is already fitted in the chassis and how many slots remain.

Lifecycle and availability

WBBP boards and the BBU3900 chassis are end-of-sale, available as new surplus or refurbished. UBBP boards and the BBU5900 remain in wider circulation. Export-control screening applies as it does to all Huawei items; we confirm per transaction.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.

New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.

Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.

Condition is confirmed in writing on every quotation before you commit to an order.

Warranty

Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.

Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.

Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.

Frequently asked questions

Some UBBP variants are supported in BBU3900, and some are not — it depends on the variant, the chassis revision and your software release. Give us all three and we will confirm before quoting.
