Wireless Backhaul Explained: The Proxim Tsunami 8100 Series

With the speed at which Internet usage and bandwidth is increasing, Wireless Backhaul has become imperative for corporations who rely on reliable, secure and fast Internet connectivity.

What is Wireless Backhaul? Imagine a human skeleton. The spine of the human skeleton is connected to the hands and feet of the body, via the limbs- the arms and legs. So, in the context of backhauling, the backhaul links in a Network are the limbs, acting as a go between; transmitting data between the core network (the spine), and the EDGE networks (the hands and feet).

A core network is the central part of a telecom network that provides various services to customers who are connected by an access network. An EDGE network (Enhanced Data rates for GSM Evolution) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM.

Traditionally, Backhaul networks have transmitted data between the core and EDGE through physical mediums, such as Ethernet cables, fiber, and copper wires. However, the ever-increasing demand for Internet service, and for the consistent quality of such service has resulted in providers constantly needing to upgrade their wired backhaul systems in an attempt to keep up.

However, Wired Backhauling is extraordinarily costly, takes months to install and scalability is limited in rural and densely populated areas. Wireless backhauling on the other hand, offers a lower cost of installation, simpler maintenance, and an achievable ROl within 6 months. Wireless systems are not hindered by geographical obstructions, enabling them to scale most areas and be installed anywhere. The Wireless alternative is also capable of powering terminal devices, unlike Wired Backhauling networks, which are unable to carry the electrical power needed to power them.

Contrary to popular belief, wireless services can also offer increased security for users as they encompass superior authentication and encryption techniques. They are also available to operate in non line of sight (NLOS) environments. One can also prevent the wireless signal from being interrupted by harsh weather conditions through thorough link budget analysis, to determine the appropriate antenna strength, and further improve reliability in the face of the elements.

A further advantage of wireless backhauling is that it offers a greatly increased range and reliability, up to 70km per link, exhibiting high data throughput over long distances, ensuring robust transfers. Latencies less than 3 ms are also now attainable through wireless, enhancing the quality of service, which is especially noticeable whilst streaming real time video and using IP based applications.

Wireless systems are also able to coexist alongside wired systems, creating a “Hybrid Backhaul” scenario.

An example of wireless backhauling in action is for building-to-building connectivity. Large corporations such as universities and hospitals, which are spread across several buildings, all demand the most robust and reliable connectivity. It is not cost effective to connect these buildings through cables or fiber, especially in urban environments. Wireless Backhauling offers a much more economical and efficient alternative, and remains flexible enough to adapt and expand in response to any structural expansion.
The most reputable company to use backhauling communications is Proxim Wireless. Proxim has over 20 years experience in the exclusive market of wireless innovation. Their Tsunami series offers service second to none.

For example, the Tsunami QB-8100 Series offers 300Mbps data rates, drawing on Proxim’s proprietary Wireless Outdoor Router Protocol (WORP), an incredibly cost-effective and high performance alternative to deliver wireless performance in excess of 4G products on the market today.

Another Tsunami range product to take note of is the Tsunami MP-8100 Series. This was the industry’s first PtMP product to provide dual Gigabit Ethernet ports with PoE out, making it the first solution capable of powering IP video cameras or additional radios for even greater ease of deployment.

The cost of the transition to wireless will pay for itself within a few months, and proves to be a more reliable, maintainable and efficient option than the cumbersome wired alternatives.
