\tVerizon and AT&T expressed enthusiasm for open RAN at an industry conference devoted to the topic, but executives from both outlined hurdles which need to be cleared before they begin deployments.<\/p>\n

Speaking at the FierceWireless Open RAN Summit, AT&T \u00a0VP of network analytics and automation Raj Savoor said it expects to start indoor deployments of open RAN roughly a year from now.<\/p>\n

Trials are \u201cgiving us confidence\u201d in the technology, he explained adding much of the hardware AT&T is deploying in its network \u201cactually has the features of open RAN built into it\u201d.<\/p>\n

The software needed to \u201cunlock those capabilities\u201d is still in development, he noted citing the service management orchestrator (SMO) and RAN intelligent controller (RIC) as elements AT&T needs to be able to deploy.<\/p>\n

\u201cThere\u2019s a lot of active work in those areas\u201d.<\/p>\n

Adam Koeppe, SVP of technology planning at Verizon, explained it is \u201cfocused on commercialising an operationally sound open RAN architecture\u201d.<\/p>\n

\u201cGenerally speaking, there are economic, commercial and technical challenges inherent in the standards process\u201d. Koeppe listed objections from existing equipment suppliers, research and development required from smaller suppliers, a need for standardisation of management interfaces and a requirement for a structured approach to ongoing enhancements.<\/p>\n

The Verizon executive argued open RAN \u201cneeds to be a well-oiled machine and continue to deliver advanced RAN capabilities\u201d.<\/p>\n

Koeppe also noted the higher operational costs which may be associated with open RAN versus traditional architectures. \u201cThere will be increasing complexity and integration costs associated with integrating different components at scale and ensuring interoperability at the level of reliability that customers demand.\u201d<\/p>\n\n
