5G FWA presents a lower-cost alternative to fibre to the home and delivers comparable speeds.

Very soon, there will be a new entrant to the connectivity landscape in India for home service—5G otherwise known as Fixed Wireless Access (FWA). This latest rival to traditional broadband internet will bring a great deal of expectation, particularly as FWA in conjunction with 5G will offer a scalable, cost efficient high-speed broadband technology with a wireless connection to provides the last mile. It is a market that is also anticipated to grow exponentially over the next five years: Globally, FWA connections are set to rise threefold providing broadband to over 800 million people by 2027, and reach US $88.5 billion, with a compound annual growth rate of 99.3%.

The rising demand for high-speed internet connectivity with lower latency will accelerate the new era of 5G FWA market expansion. In fact, 5G FWA is seen as the answer to the greatly anticipated, as yet unsatisfied, demand for high-performance broadband in regions where service is still lacking—specifically the rural area.

Part of the appeal of 5G FWA is down to the fact that it presents a lower-cost alternative to fibre to the home (FTTH) and delivers comparable speeds. In contrast to the costly and time-consuming process of digging trenches and installing fibre across various locations, FWA uses radio waves to create a connection between existing cell towers and antennas located on or in customer’s homes or businesses.

With such high revenue expectations for 5G FWA, mobile operators will rapidly seek ways to capitalize on this new opportunity. From a network planning perspective however, FWA is a marked departure from what mobile operators are typically used to and getting it right first time will be vital to ensure a good customer experience. There are therefore a number of new dimensions to take into account when planning FWA networks, including 5G customer premise equipment, new spectrum challenges, and customer KPIs. These add certain complications to the typical cellular planning scenarios. With all of the complexity and potential for planning difficulties, what are the key considerations for 5G FWA that mobile planners and engineers need to take into account as they prepare for this new service?

Height matters

In a traditional mobile network, it’s generally taken as fact that all devices are located approximately one to two meters above ground for the majority of the time. As a result, mobile signals have been optimized for various domains and spaces – for example, a person’s car, desk, kitchen counter, pocket and so on. With mobile operators now planning services for an indoor experience, this could also extend to connecting an assortment of ‘fixed’ devices located in high-rise apartments and office buildings. In these types of settings, it is essential to employ propagation models that account for various heights. When it comes to considering ‘what if’ types of scenarios, mobile operators will benefit from running their simulations in 3D to account for various heights.

Hardware becomes more conspicuous

The introduction of 5G FWA requires additional planning considerations by the operators. They need to account for FWA supporting rooftop antennas, antennas on building facades and indoor fixed terminals (or Customer Premises Equipment (CPEs)), etc. Planning tools need to be able to determine how many FWA CPE terminals are required per location and where to place them.

Choice of spectrum

5G FWA offers operators several spectrum options. Mid-band is typically the spectrum of choice today, but millimeter can also be used, and it is especially useful in an urban context.  At the same time however, its idiosyncratic nature makes it slightly more challenging to work with. Operators need to know how service is impacted depending on which spectrum band is used. For instance, if the operator opted to use another frequency, they would have to understand in advance what that would look like, and how various CPEs would perform with different frequencies.

KPIs gain new importance

Mobile operators delivering high-speed fixed broadband will need to meet certain performance KPIs. It’s essential to be able to analyse and view these on a map to help predict the user experience as part of the planning process. Planning engineers are required to know certain facts in advance: whether they have a strong enough or sufficient signal strength and signal quality; whether they have sufficient throughput; whether they analyse these KPIs by location and per CPE. Only with this certainty can operators be sure they can deliver on their promises.

New customers, increased revenue

Fundamentally, the main draw of 5G FWA from an operator’s perspective is the potential to add a significant number of new subscribers, and as a result, greatly increase revenues. As interest grows amongst prospective customers and they begin to reach out and explore their options, customer care agents will need to be able to answer questions about coverage and serviceability which will require them to have access to accurate, real-time information.

The arrival of 5G FWA brings numerous advantages, but it will also place mobile operators in unknown territory from a planning perspective. To help them navigate this environment they need the right support. The primary concern involves CPE modelling and reporting. This then becomes the substrate on which optimal 5G FWA networks can be designed. The right tools are also helpful for addressing the technology hurdles commonly associated with FWA planning processes, including 5G outdoor and indoor fixed terminal placement. Simultaneously, such tools are also key to unlocking advanced coverage and traffic analysis, combined multi-technology planning, site selection, and ‘what-if’ scenarios.

FWA is undoubtedly a disruptive technology that will drive revenues and business growth in the years to come – to guarantee its success, operators will have to play close attention to the planning and optimization.
