“EBlink’s FrontLink ™ solutions have the potential to change the way
mobile network operators deploy their networks in the near future. EBlink has proven that a distributed Radio Access Network approach was now feasible using wireless CPRI transport, without sacrificing network performance.” Stephen Bye – CTO, Senior VP Technology Development & Strategy
TCO comparison wireless fronthaul vs. fiber
Fiber
Wireless fronthaul
“EBlink
wireless fronthaul solution provides significant TCO advantage for remote RRH deployment, paving the way for new network architectures. ” Denis Fauconnier – 4G Product Management Director at Alcatel- Lucent
Wireless Fronthaul is always showing lower TCO versus a fiber based scenarios Higher TCO of fiber due to the cost of trenching for laying out a new fiber In case trenching is partially required (in the case existing fiber ducts are used), the TCO difference between fiber and wireless fronthaul decreases. However, the operator may have to incur additional lease costs to occupy the fiber duct Deploying fiber will in most cases required a larger lead time when comparing to the time to install a Wireless Fronthaul (e.g. city council permissions, time for civil works, etc.). This means that revenues that can be generated quicker with Wireless Fronthaul because of speed of deployment
Conclusion: •
Wireless Fronthaul is a key enabler for C-RAN and local C-RAN
•
Wireless CPRI is not obvious: many stringent requirements
•
Wireless fronthaul provides a flexible and costeffective interconnection between base band and Remote Radio Heads
•
mm-Waves bands are needed to support CRAN and 5G architectures
•
EBlink: leading Wireless Fronthaul, field proven solution, leading spectral efficiency (up to 7.37 Gbps CPRI )
•
EBlink participating actively in H2020 projects within the framework of 5G infrastructure PPP
