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
