Breaking down LTE adoption barriers

The communications industry should consider new ways of leveraging legacy technologies to move forward with LTE, according to Nicolas Hauswald, Director of Sales and Marketing at ETELM.

Speaking at Critical Communications World 2018 in Berlin, Hauswald said that barriers preventing users from deploying LTE could be removed by using an integrated solution rather than an interconnected solution.

According to Hauswald, private LTE has been a hot topic for several years but few deployments have been seen in the field.

This is partly because of the technical, operational and financial challenges raised by TETRA and LTE interconnection, he said.

“There are many challenges to overcome when looking at ways to connect TETRA and LTE users, including performance, features, interoperability, management, maintainability, security and costs of operation,” Hauswald commented.

“These challenges are creating barriers for users to deploy LTE.”

According to Hauswald, an integrated solution is a new approach to interconnection.

“By allowing TETRA and LTE to interwork in a unified way, the integration is not limited to the application layer and for optimum performances and maintainability, base stations from both technologies are connected to a single core and a single database,” he said.

“All the switching intelligence is centralised and both technologies appear at the radio level. In addition, all interfaces are standardised.”

Hauswald said this approach brings:

• the financial benefits of a single network
• an optimised solution for technical performance
• an answer to operational challenges
• an operational fit for hybrid solutions.
