EBlinksFrontLink 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.

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 TCOdifference between fiber and wireless fronthaul decreases. However, the operator may have toincur 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 installa Wireless Fronthaul (e.g. city council permissions, time for civil works, etc.). This means thatrevenues that can be generated quicker with Wireless Fronthaul because of speed ofdeployment
