Understanding the Importance of Reliable In-building Wireless Coverage

May 2, 2024
Discover the significance of dependable in-building wireless coverage and learn why a reliable wireless connection is essential for seamless communication and productivity indoors.

In today’s connected world, reliable in-building wireless coverage is essential. It includes enabling people to be in touch and access critical services such as voice calls, text messages, and high-speed internet while being inside a building. For an office block, a shopping mall, or an apartment building, reliable in-building wireless coverage is fundamental to people’s communication needs. As indicated by a new estimate released by the Energy Information Administration, part of the Department of Energy (EIA CBECS), there are more than 5.9 million commercial buildings in the U.S.

Latest Advancements in In-Building Wireless Technology

Given the latest figures, which showed that the total number of mobile subscriptions climbed to approximately 8. 50 million, it is evident that mobile phones continue to be in the lead. In light of the growing dependence on mobile devices and the desire to be continually connected, in-building wireless technology has improved substantially over the last few years in businesses, organizations, and people’s daily lives. Let’s look at the latest advancements in this field, including new technologies, improved coverage and capacity, and enhanced user experiences.

5G Network

5G technology offers substantially faster download and upload speeds, which enhances the overall user experience of in-building wireless networks. The share of global mobile connections using 5G in 2022 stands at 15%. In addition, reduced latency allows for real-time communication and applications that necessitate instantaneous responses, such as IoT and virtual reality devices, are supported by 5G. 5G networks can support a larger number of connected devices at once. This is critical as the number of smart devices used in buildings is projected to grow.

Small Cells and DAS

In-building wireless technologies such as small cells and distributed antenna systems are essential for enhancing cellular coverage and capacity within premises. Small cells, which are low-power cellular base stations, are often deployed in high-traffic areas such as malls, office premises, and stadiums. Small cells are used to alleviate the strain on macrocellular networks by beam-forming areas under high traffic. Small cells are deployed both outside buildings and inside, supporting multiple wireless technologies such as 4G LTE and 5G.

DAS are distribution networks of antennas placed inside a building to disperse cellular signals. They are made up of a central hub or headend, which is linked to many remote units or antennas. The remote units link to the principal cellular network. DAS can boost cellular coverage and capacity by spreading the signal further and minimizing signal loss through building materials. DAS may provide support for several wireless solutions and handle both voice and data traffic.

Internet of Things (IoT)

The other key driver of in-building wireless technology is the Internet of Things (IoT). IoT assumes connecting various devices and systems within a building. It provides unimpeded communication and automation, which can drive efficiency and productivity and enhance the overall user experience. IoT produces a huge amount of data through the interaction of its devices, sensors, and systems. The data volume generated by IoT endpoints is expected to hit 72 ZB (zettabytes) by 2025. By analyzing this data, building owners and operators can access additional trends about space utilization, power consumption, and user activity at a more granular level. This provides them with more information and motivation to optimize building performance.

Challenges and Solutions

·      Signal interferences happen with walls, furniture, and other electronic devices, especially in an in-building facility. Although it likely has a boost signal, signal boosters are available to offer a stronger signal capacity that offers more coverage and less interference.

·      The current capacity and future capability in the in-building facility are nonexistent. Most DAS deployers require an equal distribution of the wireless signal, and in an in-building facility, the location simply lacks the capability to do so as the number of wireless users and devices inherently increases.

·      Implementing in-building wireless technology can be costly, especially in large buildings. It may, however, be reduced through shared infrastructure models in which multiple wireless service providers cooperate to install and maintain infrastructure.

Market Overview, Trends and Drivers

The In-building Wireless Market size is expected to be in a position of 125 Billion USD at the end of 2036, expanding at a CAGR of 11 percent through 2024 to 2036. The industry size of in-building wireless was USD 33 billion in the year 2023. Growing demand for continuous connectivity in addition to enhanced indoor coverage is expected to drive market expansion.

There is a growing demand for seamless indoor connectivity due to smart device and IoT market trends. Over 65% of people globally own a smart device and global IoT connections example, grew 19% in 2022, surpassing 15 billion active IoT endpoints. In-building wireless solutions can meet the surge demand because of their reliability and high-speed integration options, ensuring the growing demand for data-intensive applications and services is addressed.

Smart buildings are among the most common drivers of growth in the in-building wireless market. Their number is expected to rise from 46 million this year to 118 million by 2026, an increase of over 150%. Smart buildings are constructed according to the newest top-of-the-line technology trends and are as functional and automated as possible to increase efficiency, sustainability, and user comfort. In in-building wireless solutions, the technology aids the interconnection and communication of smart buildings.

The rise of collaborative networking technology is expected to bolster the Asia Pacific in-building wireless market. As an instance, the first trial of the G-SRv6 header compression solution was achieved via the joint effort from ZTE Corporation and China Mobile with the design and deployment of G-Ran. To achieve G-SRv6, the firms combined ZTE’s high-end router with a provider edge router and a service router to create a perfectly functioning networking solution. The rise in the need for large reliable wireless cellular connections in commercial and residential building surroundings stimulates market revenues in the region.

Despite the future of the in-building wireless market looking bright, it presents some challenges to the players involved. Some of the challenges include the demand for extensive infrastructure deployment to achieve full coverage and capacity. The other challenge is the growing concerns over security and privacy as the market becomes more connected.


In conclusion, in-building wireless coverage is paramount in today’s connected world. The benefits it offers to individuals and businesses cannot be overlooked. Strong and reliable wireless signals in buildings allow people to connect, access information, and communicate without any struggles. It boosts business productivity, improves customer experience, and supports the utilization of upcoming technologies. Investing in reliable in-building wireless coverage is a wise decision that will enable increased efficiency, customer satisfaction and success.
