Inside ORS SDR

 

Schematics

 

Transceiver: analog to digital

 

FPGA: glue with PCIe

 

PA: TX (number of UEs)

  • previous TX chain: AD -> LNA -> PAs (x2) -> TDD switch -> Filter -> antenna
    • pro : had only 1 filter for both RX and TX
    • cons : filter is very big (to support RF output power) and it is adding 1.5dB loss 
  • current TX chain: AD -> LNA -> Filter -> PAs (x4) -> TDD switch -> antenna
    • note that only the TDD switch must be correctly sized for RF power (currently HMC784)
    • we have now 4 "small" filters (2 for RX and 2 for RX)

LNA: RX (range)

  • previous RX chain: Antenna -> Filter -> TDD switch -> LNA -> AD
  • current RX chain: Antenna -> TDD switch -> Filter -> LNA -> AD
  • possible improvements:
    • selective LNA depending on the freq (currently it is generic 0-6GHz LNA)
    • even thinner band for filter 

Mechanics: dissipation and interference

OSS/BSS: plug-and-play

Roadmap

 

ORS Roadmap

B46/N46, 100 Mhz, 2x10W, PTP via PTM

 

10 W PA

 

ORS derivatives

  • Built-in UE (ex. NR, starlink, Wifi)
  • Multiple frequencies (ex. 2T2R B38 + 2T2R N77)
  • More layers (ex. 4T4R, 8T8R)
  • More power (ex. 40W)
  • Support other vendors to adopt ORS design 
 

Carrier grade features

 

Performance

  • We already supply tier-1 telcos and hyperscalers
  • Most extensive 3GPP coverage for RAN (incl. NTN)
  • Tested with CISCO, Nokia, Huawei, Ericsson cores
  • More than 512 UEs (NR) tested on a single ORS
  • More than 1024 UEs (NR) simulated
  • Built-in NMS/OSS/BSS
  • 3GPP KPIs
 

Base Band Unit (BBU)

Public vRAN (D-RAN or C-RAN) • up to 192 LTE RUs or 32 NR RUs per BBU

AMD • Hygon • Intel • CPRI Split 8 • (eCPRI Split 7.2)

 

Radio Unit (RU)

Plug-and-play firmware • end-to-end test • CPRI • O-RAN

 

Strategic accelerator: independence in 3 months
