Demand for mobile data is soaring, and microwave is seen as the primary transport medium in rural and suburban areas. Aviat’s WTM 4000 enables double capacity (2+0) microwave links by housing two transceivers, two diplexers, and a 3dB coupler in one compact all-outdoor solution.

With the current landscape of network economics and challenges associated with capacity and spectrum, having multiple tools for link deployments, capacity growth, and future-proofing are necessary. In this blog, we’ll discuss the concept of Microwave Multi-Band, or the use of two different microwave frequency bands over one link, and specifically the combination of 6 GHz and 11 GHz.

With tower outsourcing increasing, operators can minimize tower lease costs by reducing the size of their microwave antennas with higher system gain radios.
The evolution of applications, services and demands on private broadband networks are creating new requirements for coverage and agility, which will require a new breed of transport for backhaul. The backhaul network must be smarter, simpler and more cost effective to be able to handle the challenge of connecting any device, anywhere.

Papua New Guinea, or PNG, is one half of the island of New Guinea, along with offshore islands, located in the South Pacific immediately to the north of the Australian continent. The country is rugged and heavily covered by dense rainforest, which presents enormous challenges when it comes to establishing a national communications infrastructure. In most cases, deploying fiber routes is simply not practical nor affordable. Wireless is the only answer in these cases.
Figure 1: SDN will not significantly reduce microwave CAPEX costs.
Software-defined networking (SDN) promises to drastically simplify how transport networks deploy, operate and get serviced. Reducing OPEX remains a significant factor for implementing software-defined networking. Automating service creation, traffic and bandwidth control, and network management as well as reducing maintenance complexity of routing protocols remain areas where it will simplify backhaul and lower OPEX. The only questions seem, “When will this happen?” and “How much will it save?” And what about CAPEX? Can we expect reduction in purchase price of microwave backhaul based on such a migration?

Throughout Africa a wind of change is blowing as mobile network operators ponder, and in many cases implement, a wave of network modernization. The trigger for this is multi-faceted. Booming subscriber growth, introduction of new data services and arrival of new undersea fiber optic cable links are combining to strain existing network infrastructure to the breaking point.
Booming Mobile Subscriber Growth
According to the GSMA , as of September 2011 Africa has overtaken Latin America with 620m mobile connections, making it the second largest mobile market in the world after Asia-Pacific. The number of connections has more than doubled over the past four years, with growth expected to continue at the fastest rate of all global regions over the next four years.
First Voice, Now Increasingly Data
Most networks across Africa were built many years ago to serve the initial rollout of 2G/GSM mobile networks that were designed to provide basic voice services. Many operators have since introduced data services using EDGE, 3G WCDMA, and, more recently 3G HSPA, putting an incredible strain on these networks. These data services can be vital for the operator, as they are often supporting premium, prepaid subscribers or new fixed line data services being offered for small and medium-size businesses.
One example of network modernization in action is in East Africa, where a mobile network operator saw subscriber numbers increase 9 percent in 2011, with 3G customers increasing more than 85 percent. This operator was also offering fixed data services to private and corporate customers through the deployment of WiMAX base stations collocated with the existing mobile sites. All this new data traffic was growing exponentially and fast outstripping the legacy backhaul network capacity. The operator also had to ensure that existing voice traffic was protected.
Priorities Driving Network Upgrades
Today, several priorities are driving network operators to upgrade their networks including the need for:
- Increased capacity
- More efficient use of backhaul spectrum resources
- Support for increasing volume of Ethernet/IP-based traffic
- Network Simplification
- Reduction in Capital and Operational Expenses
These five priorities are closely interrelated. For more details, download the complete article.
