Business case
making the backhaul business case for VectaStar
Introduction
Cambridge Broadband Networks has developed comprehensive business case modelling tools which can be used to evaluate the OPEX and CAPEX savings for an operator’s specific network, given the relevant network-specific parameters.
OPEX, CAPEX, and OPEX saving comparisons from Western Europe data
Using typical UK prices for services and equipment, the relative costs of the three key backhaul technologies, in Western Europe, are shown in the graphs above.
In this case, an operator would achieve a positive Return on Investment (RoI) in 1–2 years for a replacement VectaStar network (in a replacement network the CAPEX investment must be funded by OPEX savings alone to achieve a positive RoI) or a single year in an expansion network (where CAPEX savings can be considered as well as OPEX).
Conclusions
VectaStar’s point-to-multipoint architecture results in a backhaul network with fewer radios and fewer antennas on roofs and masts. This translates directly into reduced CAPEX and OPEX for the operator. The increased spectral efficiency and inherent ability to accommodate high peak rate traffic loads without wasting spectrum, offers a scaleable solution for high capacity 3.5/4G network migration.
With IP and E1 optimisation and pseudowire support for core IP network connectivity, VectaStar offers a solution for the immediate problem of bandwidth expansion and a migration path towards a future all IP network, without the need for a ‘fork lift’ upgrade.
- VectaStar saves operators money compared with Point-to-point microwave and Leased Line transmission.
- VectaStar is the only platform capable of aggregating all current and future access technologies.
