“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 analysis: macro sector extension TCO analysis: micro sectors densification

• 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 cost-effective interconnection between base band and Remote Radio Heads

• mm-Waves bands are needed to support C-RAN 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
