The Potential of Open Radio Access Networks in In-Building Wireless
In-building wireless solutions are becoming more attractive not only for the consumer market but also for enterprise digital transformation as 5G expands the boundaries from the consumer market to enterprise domain. Therefore, the cost of the cellular infrastructure and its associated capabilities should be flexible to enable Mobile Network Operators (MNOs), venue owners, and enterprises to select the best-of-breed equipment, reducing the Total Cost of Ownership (TCO) while meeting the coverage, capability, and capacity requirements of each specific use case. To date, Distributed Antenna Systems (DAS) and integrated small cells are well known in-building wireless solutions that effectively address coverage and capacity indoors. However, disaggregated small cell networks with open interfaces have the potential to make commercially viable the adoption of in-building wireless in medium and small multitenant buildings and enterprises, where DAS deployments could be expensive.
