Wireless Backhaul & 3G Network Economics
The profitability of emerging 3G data services over new mobile broadband networks is under threat from the cost structure inherent in legacy, voice-oriented backhaul architectures, forcing operators to accelerate investment in next-generation access and metro transmission systems.

This report examines factors driving change in mobile backhaul networks and analyzes the evolution paths of key technologies that could deliver greater capacity to the cell site, at far lower cost per bit, than is possible today.

The rollout of services over high-speed 3G High Speed Packet Access (HSPA) and CDMA2000 1x Evolution-Data Only (EV-DO) infrastructure represents a vast change in performance for the cellular industry, and could generate a requirement for tens, or even hundreds, of Mbit/s of backhaul capacity at the cell site. Traditional leased-line architectures, however, are unable to scale elegantly and cost-effectively to meet this demand. As a result, operators must investigate alternative access transmission mechanisms, from self-built microwave to digital subscriber line (DSL) and Metro Ethernet.

To optimize cost/performance ratios, the long-term vision is to move all cellular transmissions to IP/Ethernet networks. But the sector must also look to migrate more than a decade’s worth of installed time-division multiplexing (TDM) and Asynchronous Transfer Mode (ATM) infrastructure, putting the focus squarely on multiservice platforms as operators evaluate their "buy versus lease" transmission choices.

Sample research data from the report is shown in the excerpts below:

With all major operators looking at how best to meet future transmission needs, surveys indicate a near-unanimous view that spending on transport infrastructure is set to increase. The results of an online poll carried out by Light Reading are shown in the chart below. (Operator-specific responses are included in the full report.)
