- U Mobile will deploy next-generation 5G indoor coverage across 20 IGB properties, bringing seamless indoor connectivity to malls, offices and hotels.
- The initiative highlights the growing demand for indoor 5G and raises questions about cost, tenant value and multicarrier access.
What happened: U Mobile partners with IGB to roll out indoor 5G across key buildings
Malaysia’s U Mobile has agreed a significant infrastructure partnership with real estate giant IGB Berhad to deliver 5G in-building coverage across 20 of IGB’s high-traffic properties. The sites — which include major shopping centres such as Mid Valley Megamall and The Gardens Mall — account for more than 70 per cent of IGB’s retail, commercial and hospitality spaces nationwide. By bringing next-generation 5G connectivity deep inside these buildings, the companies aim to support smoother mobile experiences for tenants, visitors and workers.
The properties involved span malls, office towers, hotels and mixed-use complexes in major urban centres including Kuala Lumpur, Johor Bahru and Penang. Once deployed, the indoor network is expected to improve building management and operations, enhance digital engagement for retailers and visitors, and unlock more advanced use cases such as augmented or virtual reality shopping experiences and personalised promotions.
Under this collaboration, U Mobile will also make its indoor 5G access available to other telecom operators, enabling their customers to enjoy the same coverage without duplicating infrastructure. U Mobile executive leadership has emphasised that this is part of its broader commitment to expanding next-generation connectivity in line with Malaysia’s digital transformation goals. IGB leadership described the deal as strategic, future-proofing its real estate assets as connectivity becomes an expectation in world-class developments.
This indoor initiative builds on U Mobile’s wider 5G rollout plans. Earlier in the year, U Mobile has been working with partners such as OCK Group to accelerate in-building coverage and intelligent infrastructure deployment nationwide.

Why it’s important
As mobile users increasingly demand strong data performance not only outdoors but also inside buildings, in-building 5G coverage is emerging as a key battleground for operators. Urban retail centres, large offices and hospitality venues often suffer from weak signals due to structural barriers, and seamless internal coverage can improve customer satisfaction, tenant retention and operational efficiency.
Deploying advanced indoor coverage at scale, however, presents both technical and economic challenges. The cost of building distributed antenna systems and small cells throughout large complexes can be high, and returns on investment depend on tenant uptake, enhanced digital services and potential rental premium justifications. There is also a question of who ultimately benefits most: tenants, visitors or the property owner. Operators must balance the cost of deployment with expected gains in customer loyalty and revenue, particularly when networks are offered wholesale to competitors.
Another debate revolves around multicarrier access. Allowing other telcos to use U Mobile’s infrastructure could reduce duplication and drive cost efficiency, but it also raises complexities in terms of service quality agreements, shared network load and pricing. How these arrangements will work in practice is yet to be fully demonstrated.
