Challanges

Results

Throughput –All OK Latency – All OK Availability – All OK MTBF – All OK Jitter – All OK Ranges from 150 – 500Mbps dependent on vendor

Performance

SLA Targets - Wide range of alignment types Manual vs Auto vs Any Bracket types effect install times. DC vs AC.

Installation

Time/Complexity

Some Management Systems more developed than others. Power cycling/ reliability requires subcontractor on short SLAs

Operations

Issues Wireless Backhaul

Enhanced TPut Power

Higher frequency attenuated by rainfall/humidity. Not sufficient to effect PHY rate 60 GHz impacted by street works in line of sight (Christmas lights)

Environmental

•  The  Fastback  IBR  uses  MIMO  for  maximum  throughput  performance  

•  Transmit  and  receive  antennas  leverage  polariza>on,  spa>al  and  angular  diversity  maximising  link  robustness  

•  FDD  radio  enables  simultaneous  TX  &  RX  and  monitor  channel  for  fast  interference/radar  event  mi>ga>on  

•  The  result  is  an  AnyLoS  radio  system  that  works  with  direct,  refracted  and  reflected  radio  signals  

Typical  IBR  results  

25  

•  Fastback  IBR  delivers  high  throughput  across  a  wide  range  of  scenarios  and  degrees  of  obstruc>on  

•  Capacity  rarely  drops  below  200Mbps  –  even  in  urban,  high-­‐obstruc>on  situa>ons  

•  Latency  is    typical  <500μsec  •  Rain  has  negligible  effect  •  Long  LOS  distances  can  be  

achieved  in  rural,  urban  mul>-­‐story  and  over  water  scenarios

Conclusions  

26  

•  Fastback  IBR  radio  and  antenna  design  enables  AnyLoS  capability  from  a  single  radio  product  

•  NLOS  performance  rarely  dropped  below  200Mbps  capacity  and  latency  is  typical  <500μsec  –  even  in  high  obstruc>on  scenarios  

•  Fastback  met  small  cell  backhaul  trial  SLA’s  in  all  weather  condi>ons  (rain,  wind)  

•  Only  solu7on  that  provided  LOS  and  NLOS:  reduces  installa7on  complexity  and  number  of  links
