Your office has great Wi-Fi. So why are employees still complaining about mobile signal?
Modern offices have never been more digitally enabled. High-speed fibre, enterprise-grade Wi-Fi, cloud-based applications, smart building systems and collaborative technology are now expected features of a high-quality workplace. Businesses have invested heavily in creating environments designed around a workforce that is more mobile, flexible and digitally dependent than ever before.
Yet there is a familiar frustration that persists in office building. Employees walking towards a window to make a mobile call. Calls dropping when someone moves into a meeting room. Visitors unable to get a reliable signal at reception. Authentication texts taking too long to arrive. Mobile data disappearing as soon as someone enters certain parts of the building.
Wi-Fi and mobile coverage are not the same thing. They perform different roles, operate on different networks and solve different problems. A fully connected workplace needs both.
We have changed the office, but have we updated the infrastructure with it?
Hybrid working has changed when and why people come into the workplace. Fixed desks have given way to flexible spaces. Meetings increasingly combine people in the room with colleagues joining remotely. Cloud applications have become central to day-to-day working.
At the same time, the role of the mobile phone has expanded. It is no longer just for making calls. Employees use their phones for messaging, authentication, collaboration, banking, travel, building access and countless other services throughout the working day. Visitors and contractors may rely almost entirely on their own cellular connection while they are in a building.
Reliable mobile connectivity is now a fundamental part of the digital experience people expect from a modern workplace. But while expectations have changed, investment in workplace technology hasn’t always kept pace.
Wi-Fi is now a standard consideration when designing or fitting out an office. Mobile coverage, however, is often approached differently, with an assumption that a strong outdoor signal will naturally translate into reliable coverage indoors.
What does good indoor mobile coverage actually look like?
The best connectivity is often the connectivity nobody notices. People don’t walk into an office and celebrate the fact that their phone has signal. They just expect it to work.
Good indoor cellular coverage means employees, tenants and visitors can use their mobile devices naturally throughout the building. Making calls, sending messages and accessing data without having to find the nearest window or rely on Wi-Fi. But delivering that experience consistently isn’t always possible from the outdoor mobile network alone. In many buildings, dedicated indoor mobile infrastructure is needed to bring cellular coverage inside and distribute it where people actually need it.
Depending on the building, this could be a Distributed Antenna System (DAS) or an indoor small-cell solution. The right approach will depend on the size and layout of the property, the number of people using it, the existing infrastructure and the needs of its occupiers. Ultimately, it means mobile coverage can be designed into the building and managed as part of the wider digital experience, rather than simply being left to chance.
Why great Wi-Fi isn’t enough
This brings us back to an important question: if an office already has excellent Wi-Fi, why does it also need reliable indoor mobile coverage?
The answer is that Wi-Fi and cellular networks serve different, but equally important, purposes within a modern workplace. Wi-Fi provides the high-capacity local connectivity that supports corporate networks, laptops, collaboration platforms, smart building systems and an increasing number of connected devices. Cellular coverage, on the other hand, gives people direct access to the public mobile networks they use every day for calls, messaging, mobile data, authentication and their personal devices.
While there is some overlap between the two, one should not be expected to compensate for weaknesses in the other. A strong Wi-Fi network does not remove the need for reliable mobile coverage, just as good cellular coverage does not replace the role of Wi-Fi within the workplace.
The most effective approach is therefore to consider Wi-Fi and cellular as complementary parts of the same digital experience. When both work well, employees can move around the office without having to think about how they are connected, while visitors can use their phones naturally without needing to join a private Wi-Fi network simply to stay connected.
For landlords, developers and occupiers, the question should not be whether to invest in Wi-Fi or mobile coverage. It should be how both can work together to create a building where people can connect reliably and easily, wherever they are and however they choose to work.
Why neutral host infrastructure matters
There’s another important consideration for landlords and developers, everyone using a building won’t be on the same mobile network.
Providing strong coverage for one operator might work well for some people, but it doesn’t solve the problem for everyone. In a busy, multi-tenant office, employees, visitors and different organisations could all be using different mobile providers. That’s where a neutral host indoor mobile network can make a difference.
Instead of installing separate infrastructure for individual operators, a neutral host approach uses shared infrastructure designed to support multiple mobile networks within the same building.
For landlords, developers and occupiers, this creates a much simpler and more joined-up approach. One managed indoor infrastructure platform supporting multiple operators and providing a more consistent experience for everyone using the space. This is particularly valuable in multi-tenant buildings, where landlords have no control over which mobile provider an employee, tenant or visitor chooses.
Ultimately, the indoor network should work for the people using the building, regardless of which mobile operator they happen to be with.
The most connected buildings are designed around people
As offices continue to evolve, so will expectations of the digital experience they provide. The conversation therefore needs to move beyond whether a building has Wi-Fi, fibre or 5G. These technologies all have an important role to play, but what really matters is the experience they create for the people using the building.
Can someone make a reliable mobile call from their desk? Can a visitor stay connected without having to join a private Wi-Fi network? Can people move around the building without losing service?
These are the things people notice, not the technology working behind them.
For landlords, developers and occupiers, that means thinking about Wi-Fi and cellular coverage as complementary parts of the same digital experience. Each serves a different purpose and the strongest workplaces are designed to make both work well.
At WIG, we design, build and operate dedicated indoor mobile networks that work alongside existing Wi-Fi infrastructure, providing reliable multi-operator cellular coverage throughout buildings. Wi-Fi and cellular don’t need to compete for the job of connecting the modern workplace. The best buildings are designed with both in mind.
