Finding affordable and unified wireless backhaul can be very challenging in a developing region such as Africa, say experts in this area of ICT network infrastructure, and is forcing mobile operators to possess broad skill sets to effectively handle the different components of the system.

One of the reasons why it represents a challenge is because different segments of the network (small cells backhaul, macro cell backhaul, aggregation metro and long haul) are often built with incompatible equipment from different vendors, says Amit Ancikovsky, regional director for Africa at Ceragon Networks, a global wireless backhaul specialist.

The company is focused on transmission capacity required by mobile and fixed-line carriers, and private network operators to deliver voice and data services.

Unified wireless backhaul is key to improving staff productivity and operational efficiency says Ancikovsky. "A unified wireless backhaul solution streamlines planning, deployment, operation and maintenance skill set."

Why is this relevant to Africa? "The more efficient your operation is, the more you can invest in providing high quality service to your subscribers, enhancing average revenue per user and reducing churn," says Ancikovsky. "Enhanced productivity, as well as many capacity boosting, power saving and future proofing capabilities are key to increasing operational efficiency."

Africa has arrived at an interesting juncture in terms of its technology development and Ceragon Networks' view is that the continent is undergoing modernisation and the processes involved present an opportunity to streamline operators' staff skill sets.

Addressing fragmented support

The fragmented scenario in which various technologies from different vendors are meshed cannot always be prevented. Ancikovsky explains that not all vendors have a unified wireless backhaul solution to cover all wireless backhaul needs, including backhaul for smart cells, short haul, metro and trunk/long-haul.

From the point of view of the African continent, the upgrade of Radio Access Network infrastructure, characterised by the introduction of 3G or 4G, for example, is a unique opportunity to streamline and future proof wireless backhaul infrastructure.

Of course cost is always a consideration when it comes to technology procurement and application, specifically for businesses in emerging markets, Ancikovsky acknowledges, but he makes the point that it is necessary to review the total cost of ownership of the candidate solution before selecting the best fit for the network.

"While equipment price is important, factors such as reducing related CAPEX/OPEX for achieving better operational efficiency, future proofing the network for peace of mind and having a more reliable network for better service quality have to be evaluated in order to make the right decision," he continues.
