Flanger for PCS Backhaul
Increasingly, PCS operators are looking for ways to minimize their backhaul expenses, while still maintaining a reliable link. In North America a large percentage of T1 circuits are leased lines from the telephone company, with the traditional alternative being licensed microwave radios. In the former, the result is an expensive monthly recurring charge to the local carrier, whereas in the latter, there is a substantial upfront expense both in terms of time (labor) and equipment.
So, when Greg Selig, the director of operations and engineering for Airadigm Communications, went looking for wireless T1 replacement technology, he turned to Flanger by Memorylink. Mr. Selig was focused on two things: ensuring that the PCS operator’s GSM network remained up and running, and seeing to it that every dollar he spends on infrastructure delivers the highest possible rate of return. What he discovered with Flanger, was both superior reliability and astonishing ROI rolled into one neat little package.
Flanger by Memorylink has been designed from the ground up to work with cost-effective license-free Ethernet radios. Airadigm installed an initial test link in a relatively difficult radio frequency environment, using Motorola Canopy radios and the Flanger multiplexer. “Flanger was simple to install in our GSM network, with no interruption of our network services through the wireless T1 link”, said Kenneth Hoeffle, Airadigm President and COO. “Flanger is a reliable product that will save Airadigm a substantial amount of money over time by replacing leased-lines”.
Since the initial successful trial, Airadigm, which operates throughout Wisconsin and Iowa under the Einstein PCS name, has replaced a significant number of leased links as well as installing the solution for new build-out. The product is now an important piece of the company’s backhaul strategy, working in plug and play fashion alongside the Ericsson GSM infrastructure in the Airadigm system.
Another GSM operator has selected Flanger to deliver backhaul links for a group of Cingular (ATT) affiliates throughout the Midwest. BugTussel LLC works with small regional operators to deliver roaming and retail PCS services in areas where the economics dictate the services be delivered at the best possible cost while maintaining stringent network performance requirements. To achieve this, the company turned to Memorylink’s Flanger, and continues to deploy this solution, primarily with Motorola radios alongside Nokia Ultrasight infrastructure, to deliver backhaul links throughout a four-state region.
And it’s not just the ideal solution for GSM systems. The company has successful deployments in numerous CDMA systems across North America, stretching from Alaska to Florida, and with numerous infrastructure vendors and radio manufacturers.
While PCS backhaul is perhaps the most demanding of applications, and Memorylink’s demonstrated success in this space validates the superiority of the product, Flanger is also being used extensively for connecting pbx systems, T1/E1 replacement and extension for telcos, and remote emergency/disaster recovery.
Customers who use Memorylink’s Flanger will tell you it delivers TDM1 over IP with an unmatched combination of price and reliability.
Since 1998 Memorylink has been delivering innovative communication solutions, allowing customers to communicate in new, creative, and cost-effective ways, by delivering voice, video, and data over wireless links.
