You might wonder how data is transmitted from one point to another - case in point, a text message, a call or even an email message. The process is referred to in the industry as mobile backhaul. Also known as wireless backhaul, mobile backhaul is the use of wireless communications to get data to and from an end user to a node. Nodes could either be connection points, end points or redistribution points for data transmission. Mobile backhaul can also refer to the transmission of data over a wireless route, thus “wireless backhaul”.

If you’re looking for an anatomical analogy, think of mobile backhaul as the limbs of the body connecting the backbone, or core network, to a series of smaller sub-networks. Taking a cue from the analogy, the core network would serve as the ‘spine’ while the sub-networks would refer to the fingers and toes.

Basically, information travelling from a wireless tower to a mobile switching center is the portion we consider as the mobile backhaul. Within the context of satellite communication, mobile backhaul refers to getting data to a point where it can be distributed over a wider network. Web browsing, phone calls, SMS and even online games travel the mobile backhaul portion. Examples of mobile backhaul technology include the Ethernet and free space optics.

However, the most popular and common form of mobile backhaul is via microwave systems. This refers to point-to-point microwave radio relay transmission which is a technology used in transmitting digital and analog signals. It is also commonly used by major broadcasting companies to get video, as well as audio materials, for live event coverage or on-site news reporting. There are many other uses of mobile backhaul. Companies offering the technology include services like public wi-fi hotspots backhaul, IP video surveillance security systems and even public safety network redundancy. However, mobile backhaul portions are under increasing pressure with the rise of mobile devices like smartphones. Bandwidth-intensive broadband applications affect the performance of mobile backhaul networks. Companies offering wireless technology offer solutions to bolster the capacity of mobile backhaul networks at a lower cost and an increase in flexibility. Providers have also considered switching to more effective packet-based networks for their mobile backhaul technologies instead of the traditional time-division multiplexing networks.

Technologies requiring more and more bandwidth have led to the development of mobile backhaul systems that ensure real-time, end-to-end insight into network performance. Developments include support for 3G and 4G services that can handle the increased demand of e-commerce, Internet and video traffic. The primary benefits of the technology have focused on cost-effectiveness and relative performance.

Another situation where there is a need for mobile backhaul include cellular services requiring long-range broadband. Often, the wireless route is preferred in such instances wherein the normal route is unavailable or even overtaxed. Gadgets, especially smartphones, are offering more data needed to be downloaded or transmitted, through applications like video conferencing. By eliminating the need for a wired infrastructure, mobile backhaul covers a smaller amount of space while providing “Last Mile Connectivity” to expand the wireless range even to the remotest of locations.

Like VSAT systems, mobile backhaul services can be deployed almost anywhere because of the little need for physical infrastructure. Whether as a service provider or end user, mobile backhaul presents the most effective and affordable solution to communication needs that require large amounts of data transmission coupled with expanding bandwidth demand. Mobile backhaul can seamlessly evolve to accommodate network changes while handling existing technologies. Overall, it’s a technological investment that offers not just potential but tangible capacity to expand, adapt, connect and most importantly simplify wireless network coverage.
