Have you heard the buzz about Multi-Band? Multi-Band combines traditional microwave channel alongside an E-Band (80 GHz) channel, joining the capacity of the latter with the high availability of the former. Multi-Band makes E-Band carrier-class over longer distances, making it a much more viable and deployable solution for 5G backhaul.
Without becoming reality, 5G mobile communications have already captured the imagination of operators and technology providers. So can the general public catch up with the hype soon? We’ll see. Meantime, behind-the-scenes mechanics of prepping for 5G continue, building on prior technologies. At each step of the evolution of backhaul infrastructure, different challenges cropped up.

Aviat Networks Chief Product Officer Ola Gustafsson talks about SDN 5G backhaul during AfricaCom 2016.
The most pressing business need in many networks deals with delivery of new services.The biggest evolution today in the backhaul network is the trend toward integration of IP/MPLS intelligence into microwave. Software-defined networking (SDN) remains another more recent trend in backhaul. However, as we’ve posted many times, integration of IP/MPLS intelligence into microwave systems provides a number of benefits. These include lower cost, fewer boxes to buy/deploy/maintain and better network performance overall such as lower latency and better reliability.
Through various innovations, wireless transport technology has consistently surpassed capacity demands through 2G, 3G and 4G transitions and remains on trajectory to continue in a 5G network. Reliability of wireless backhaul products has never been better, and costs continue to decline especially relative to fiber-based options. From a product point of view, many good and reliable options exist that cover all frequency bands and form factors to solve the problem of backhaul, small cell and other sub-applications.

In many wireless networks, transport engineering looks after the microwave radio function while the IT department has domain over IP equipment. These two organizations started independently and grew separately over many years. It did not seem that there was any problem with this arrangement.
However, it led to the selection of equipment—radios and routers—that worked really well on their own but had no awareness of one another. Not surprisingly, these technology solutions did not perform together optimally.
