Comsol’s Pronk on the future role of wireless access in a mixed

The demand for wireless in high-density fibre areas of South Africa continues unabated. This is according to Brenden Pronk, chief commercial officer of Comsol, who says that, even in the most dense fibre areas, Comsol and its biggest ISP client continue to deploy a significant number of wireless links.

A review of the wireless deployments the company has been involved in over the past two years confirms that demand for wireless has been both constant and significant, he adds, with 69% of their wireless deployments during that time being within high-density fibre areas.

Comsol’s experience is that telcos and ISPs are using wireless as an interim solution while they wait through the long lead times associated with fibre, and most are keeping these wireless installations as their backup disaster recovery plans. However, some clients get tired of waiting for fibre and make the decision to keep wireless as their primary connection after all.

“This is because wireless is an increasingly sophisticated yet affordable solution, offering speed, reliability, and high levels of uptime, particularly if it is coming off licensed spectrum as ours does,” says Pronk.

The extensive deployment of fibre in metro areas has reduced the distance between available nodes and exchanges, so eliminating the need for multiple and expensive hops.

Add to this the fact that fibre deployment has made bandwidth cheaper due to both the larger backhaul capacities (intermediate links between the core network and sub-networks) and economies of scale on the respective carrier networks, and the cost of interconnectivity for a last mile wireless option is further reduced, he adds.

Fibre promises speed, performance and reliability, but it faces the challenges of long lead times, fixed infrastructure, high levels of feasibility failure, and high deployment costs, Pronk says. A last mile licensed wireless solution – the final stage of the connectivity process between the telco and the client – bridges the gap and provides a competitive and complementary service for the last mile access component.

He points out that a wireless last mile adds many commercial and strategic benefits:
