PTP Backhaul’s Vital Link

By    October 30, 2013

Connecting the unconnected continues to appear in the news cycle. One week ago, awarded US$2 million to the De Novo Group to bring affordable Internet connectivity to rural parts of California. But in all of the articles and white papers I’ve read on the topic of universal connectivity, backhaul is rarely brought up – strange, given that it’s the starting point of any new network architecture. Internet connections in any community or environment can only be established with a point-to-point (PTP) backhaul link that connects the global Internet to a new network hub. If a provider’s backhaul link is underperforming, every subscriber downstream is affected. This is why it is incredibly important for a provider’s PTP modules to be supremely reliable and available on a 24/7 basis. At the very least, it would save companies thousands of angry calls to their customer service lines!

Because PTP is a necessary conduit and networks have a variety of needs and masters, we pride ourselves in being able to offer a varied portfolio of PTP products. Network architects always start with these two questions in mind – “Who am I connecting? Where are they?” The answers determine which PTP solutions are put into place. Cambium Networks’ family of PTP wireless access and backhaul radios includes modules that operate in unlicensed and licensed frequencies; provide long or short links; and have high or low capacity. When a network’s requirements change, legacy PTP links can simply be moved and repurposed within the network as needed: Nothing is ever wasted.

One of our long-term customers, Guadalupe Valley Electric Cooperative (GVEC), whose coverage area spans a 3,500-square-mile swath of central Texas, built the network of its dreams with a garden variety of our PTP products: PTP 300, 500, 600 and 800 systems. GVEC’s solutions were tailored to its needs as a provider of electricity and high-speed wireless Internet to businesses and residents. For example, the PTP 300 provides communications to a third-party banking customer, and 15 PTP 800 radios provide backhaul to the cooperative’s electric substations and throughout the overall communication system. Many of GVEC’s subscribers were left behind when larger carriers uprooted their operations so it is committed to providing reliable, high-quality access on a consistent basis. We are happy to aid in this noble cause and look forward to the imminent unveiling of an attractive addition to our PTP portfolio.
