Huawei UBBPd5 — universal baseband processing unit
- Part number
- UBBPd5
- Manufacturer
- Huawei
The UBBPd5 is the mid-tier d-series baseband board, carrying GSM, UMTS, LTE FDD and NB-IoT. It is physically identical to the UBBPd6 in form factor and port count, which is why the two are frequently offered interchangeably. They are not interchangeable: the d5 has no LTE TDD support whatsoever, and carries roughly half the capacity of the d6 in every other dimension.
