Wireless Backhaul Saves Capital, Operating Expense

Mobile service providers may not have either the money or the time to move to fiber for backhaul, and even if they have the money, fiber facilities might be available where they need it, argues Monica Paolini, owner of Senza Fili Consulting.

Wireless backhaul can save mobile operators a great deal of money, Senza Fili Consulting says.

Wireless backhaul requires a higher initial expenditure than leased fiber, but subsequent operating expense is lower. This makes wireless backhaul a more expensive solution than leased fiber in the first year, in developed markets.

In a developed market, wireless backhaul can save mobile operators 26 percent over leased fiber, and 42 percent over built fiber over ten years. In an emerging market, service providers save 59 percent over leased fiber and 68 percent over built fiber.

By deploying wireless backhaul initially and gradually transitioning to fiber, operators can reduce the net present value of their backhaul upgrade by seven percent in a developed market and 31 percent  in an emerging market, compared with leased fiber access.

In developed markets, wireless backhaul produces savings of 14 percent over built fiber, with savings of 27 percent in an emerging market.

The analysis suggests that when mobile service providers have access to spectrum, they may save money by initially deploying a wireless backhaul solution that is paid off in a short period, and moving to fiber gradually at a later time, when and where it becomes available or cost effective, or when the operator is ready to deploy it.

Mobile service providers may not have either the money or the time to move to fiber for backhaul, and even if they have the money, fiber facilities might be available where they need it, argues Monica Paolini, owner of Senza Fili Consulting.

A solution, she argues, is to use wireless backhaul first, then gradually transition to fiber as facilities are available and as bandwidth needs require fiber.

Wireless backhaul requires a higher initial expenditure than leased fiber, but subsequent operating expense is lower. This makes wireless backhaul a more expensive solution than leased fiber in the first year, in developed markets.

After the break-even point in the second year, though, wireless backhaul costs less. In the emerging market scenario, wireless backhaul is the lowest-cost solution from the start, a white paper suggests.

In a developed market, wireless backhaul can save mobile operators 26 percent over leased fiber, and 42 percent over built fiber over ten years. In an emerging market, service providers save 59 percent over leased fiber and 68 percent over built fiber.

By deploying wireless backhaul initially and gradually transitioning to fiber, operators can reduce the net present value of their backhaul upgrade by seven percent in a developed market and 31 percent  in an emerging market, compared with leased fiber access.

Nokia Siemens Networks Publishes Book on Mobile Backhaul

By 2015, mobile operators will be paying €13 billion a year for backhaul leasing. Operators also face the challenge of high costs as they upgrade backhaul networks to support high data rates, often involving a change in backhaul technology, as well as adding capacity.

These are big reasons for operators to look at ways to claw back some of the cash outflow by setting up their own cost-efficient mobile backhaul, Nokia Siemens Networks argues in a new book, Mobile Backhaul.

Helping people to understand better how to set up backhaul to effectively support mobile radio technologies was the mission that Nokia Siemens Networks took on in its new book, Mobile Backhaul (Wiley 2012).

The first publication to take an end-to-end view of the complete subject, the book looks at both the radio network and IP network sides of the equation. Of course, radio networks have been covered before and IP networks have also been written about extensively, but never as part of a cohesive whole that explores the importance of both aspects to the mobile backhaul system.

Ethernet Access Device Sales Up 17% in 2011

The Ethernet access device market grew 17 percent in 2011 over 2010 and is forecast to grow 81 percent between 2012 and 2016, says Infonetics Research.

The key trend driving demand for Ethernet access devices (EADs) is rapid service provider rollout and customer uptake of Ethernet connections and services, Infonetics says.

Fiber EADs currently make up 70 percent of all EAD purchases; copper EADs (Ethernet over TDM bonded circuit, or EoTDM EADs, and Ethernet First Mile bonded copper, or EFM EADs), make up the remaining 30 percent.
