Ookla’s Speedtest® data indicates that a router’s suboptimal placement can negatively impact in-home Wi-Fi.
The Gulf region has one of the highest levels of fiber penetration in the world. However, the persistent bottleneck for internet performance often lies within the home itself and specifically, the quality and placement of Customer Premises Equipment (CPE). Addressing this bottleneck can unlock the full potential of fiber and deliver the promise of gigabit fiber to a wider base of subscribers. We use Ookla’s Speedtest data to investigate the impact of CPE placement on home Wi-Fi performance using data from Qatar, Saudi Arabia, and the U.A.E., assess how different Wi-Fi standards influence this relationship, and provide practical solutions to mitigate the in-home performance gap.
Key Takeaways:
- Distance from the router and obstacles like walls can make Wi-Fi performance drop significantly. As a user’s device moves away from the Customer Premises Equipment (CPE) or is separated by walls, a device’s Received Signal Strength Indicator (RSSI) (measured in dBm) declines, deteriorating median download speed. Ookla’s Speedtest data shows that this relationship is not linear: it sets a ceiling where speed starts to level off, and conversely, a point beyond which performance degradation accelerates.
- Every new Wi-Fi standard introduced innovations that pushed both the maximum throughput ceiling and the RSSI breaking point further. Speed improvements for Wi-Fi 4, 5, and 6 generally plateau beyond –40 dBm. On the other hand, performance deteriorates rapidly below –60 dBm. Newer standards, namely Wi-Fi 6 and 7, extend the usable RSSI range before hitting the performance cliff.
- While Wi-Fi 7 is more data-efficient than its predecessors, its “breaking point” in the U.A.E. is reached at a shorter distance (i.e., stronger signal) than in Qatar and Saudi Arabia. Users in the U.A.E., known for its high urban density and the use of low-emissive (low-E) glass to reflect light and heat, experience accelerated degradation at around –55 dBm, which is likely due to co-channel interference and signal degradation. This shows that local environmental factors can influence RSSI breaking points.
- The choice of spectrum bands dictates the balance between high throughput and signal resilience against physical barriers. The 5 GHz band allows higher speeds but suffers from a sharp decline in performance, with speed deterioration accelerating below –60 dBm, resulting in a loss of 30% to 44% in speed over a 10 dB drop. Conversely, the 6 GHz band’s lack of congestion allows it to maintain very high speeds (often above 100 Mbps at –80 dBm), effectively compensating for its higher susceptibility to signal absorption.
In-home Wi-Fi throughput is directly correlated with signal strength
We previously identified that the indoor Wi-Fi network could be a bottleneck to delivering fiber’s high throughput. In Gulf countries, including Bahrain, Jordan, Qatar, Saudi Arabia, and the U.A.E., we saw download and upload speeds improve as ISPs introduced multi-gigabit plans and raised entry-level packages’ speed. The growing adoption of new CPEs that support Wi-Fi 6/7 standards is helping significantly boost the in-home broadband speed, but legacy Wi-Fi (Wi-Fi 4 and 5) remains a limitation for some users. The choice of a spectrum band (2.4 GHz vs. 5 GHz) also balances capacity and reach.
Beyond the CPE’s Wi-Fi standard and spectrum band, its physical placement and the inherent limitations of indoor propagation through obstacles, due to increased use of insulating materials and low-emissivity glass, impact the connected experience indoors. We use Ookla’s Speedtest data to assess the relationship between measured Wi-Fi download speed and RSSI (the power of the signal received by the end-user device). This metric serves as a proxy for the factors that could affect the relationship between the router and the user’s device.
We also look at how this relation shifts depending on the Wi-Fi generation (4, 5, 6, and 7) and the spectrum band used (2.4 GHz, 5 GHz, and 6 GHz). We identified fixed broadband CPEs where connected devices conducted multiple tests with different RSSI levels (between October 2025 and February 2026), and collected the corresponding median download speed readings.
RSSI measurements use a logarithmic scale where values closer to zero indicate a stronger signal. RSSI typically ranges from –10 dBm in direct proximity of the CPE to –90 dBm at the edge of the network. For the signal from the router to be accurately interpreted, it must arrive with enough power to be distinguishable from the background noise floor, defined as Signal-to-Noise Ratio (SNR) (this analysis focuses solely on RSSI).

The chart below shows a clear and consistent speed deterioration as RSSI values decline. In Saudi Arabia, a device receiving a signal of –30 dBm, indicating clear line-of-sight of the router, achieves a median download speed much higher than when the signal weakens to a range of –60 to –70 dBm, which can be caused by distance or a separating wall. Above –60 dBm, performance trends start to diverge considerably, reflecting differences in terms of fiber penetration levels, proportion of households with 500+ Mbps packages, and the share of CPEs with modern standards. The result is that users in Qatar and the U.A.E. achieve much higher download speeds than those in Saudi Arabia.

Dynamic Rate Shifting (DRS) explains this rapid decline in download speed. Wi-Fi devices automatically negotiate their Modulation and Coding Scheme (MCS) based on the link quality. When the RSSI is high (and the SNR is healthy), the system uses complex modulation, which packs more bits into radio signals, but they are extremely sensitive to interference and noise. At higher distances, the Wi-Fi system ‘downshifts’ from complex to simpler modulations to maintain connection stability at the cost of a lower bitrate, leading to eventual collapse as increased retransmission adds latency and jitter to the connection.
How Wi-Fi standards can alter the RSSI-speed equation
The impact of signal degradation is not uniform across all technology generations. Each successive Wi-Fi standard introduced innovations in modulation techniques and antenna design (as shown in the table below) to increase the maximum throughput ceiling and the resilience of the signal at the edges of the coverage area.
In this analysis, we focus on the rate of change in download speeds for a given RSSI range rather than look at the absolute throughput to account for differences between the three countries in terms of achievable median download speeds. This approach also excludes the effect of selection bias, for example, that faster broadband subscriptions are generally bundled with more modern CPEs.
Speedtest data represented in the chart below shows that Wi-Fi 4 performance is largely flat across a wide range of RSSI values higher than -40 dBm, creating an early upside ceiling. In Saudi Arabia, Wi-Fi 4 median speeds remain between 30 and 40 Mbps even when the device is close to the router (–20 dBm) and only begin to fall significantly when the signal drops below –60 dBm. In Qatar and the U.A.E., Wi-Fi 4 performance also hits a hard ceiling at around 50 Mbps; as the signal strengthens beyond –40 dBm, download speeds stop growing (excluding a few outliers), plateauing even when the device is very close to the router. This demonstrates the technical limitations of Wi-Fi 4.

Transitioning to Wi-Fi 5 marks a leap in terms of performance compared to Wi-Fi 4 with the use of the 5GHz band, a more complex modulation scheme, refining beamforming, and introducing MU-MIMO. This is reflected in the wider envelope with higher speeds in good-to-excellent signal conditions. However, speed improvements somewhat decelerate around –40 dBm with more incremental increases between 200 Mbps and 300 Mbps.
The chart below shows a steep decline in speed as distance (or number of obstacles) increases, starting from an RSSI of -50 dBm. For example, in Saudi Arabia, speed drops from 193.90 Mbps at –50 dBm to 99.07 Mbps at –70 dBm—a close to 50% loss over 20 dB. Similar rates of speed decline are registered for Qatar and the U.A.E. around this RSSI “breaking point”. This rapid decline can be attributed to the use of the 5 GHz band, which has shorter wavelengths that are more heavily attenuated by concrete and brick.

Wi-Fi 6 extended performance further than Wi-Fi 5, as it introduces a higher-order modulation technique (i.e., 1024-QAM), which yields a 25% gain in throughput compared to the previous standard. The chart below, based on Speedtest data, shows two clear inflection points for performance:
- When RSSI is above –45 dBm, speed improvements decelerate in Qatar and the U.A.E. and stabilize in Saudi Arabia. This shows that further signal strength, for example, by moving closer to the CPE, provides little to no benefit or even risks receiver saturation. Saudi Arabia trails Qatar and the U.A.E. due to lower Wi-Fi 6 adoption and a smaller share of 500+ Mbps median download speed samples.
- When RSSI is lower than –55 dBm, a steep decline in download speeds occurs due to increased packet losses and the necessity for retransmissions.

Wi-Fi 7, which incorporates the Multi-Link Operation (MLO) functionality previously detailed, enhances the foundations of Wi-Fi 6 with higher-order modulation (i.e., 4096-QAM) for a further 20% gain in modulation density, which translates into improved speed. As the current peak of wireless innovation, it offers the strongest potential, especially as Gulf operators roll out multi-gigabit home broadband packages.
While fewer samples were collected compared to earlier Wi-Fi standards, data shows that Wi-Fi 7 is most resilient at low RSSI levels, extending the range of excellent performance. For example, Qatar maintains high median speeds (exceeding 500 Mbps) in the –60 to –70 dBm range before the decline accelerates. In Saudi Arabia, even at an RSSI of –80 dBm (close to the noise floor where the connection is supposed to be unusable), the median download speed reached 75.81 Mbps, nearly doubling the performance of Wi-Fi 6 (39.11 Mbps) at the same level. The advanced modulation scheme, alongside features such as OFDMA, MLO, and Preamble Puncturing (see above), explains this resilience, allowing Wi-Fi 7 to maintain a usable SNR at lower power levels than its predecessors.
In the U.A.E., the ‘breaking point’ at which the deterioration of the network accelerates occurs significantly earlier than in Qatar and Saudi Arabia, with an RSSI of around –55 dBm, as shown in the chart below. Median speeds drop from around 641.61 Mbps at –50 dBm to 549.45 Mbps at –55 dBm, and continue to fall to 416.01 Mbps by –59 dBm. This behavior can be attributed to the prevalence of high-rise buildings in the U.A.E and high urban density, which leads to co-channel interference. Even with a strong RSSI of –55 dBm, a high noise floor from neighboring networks can lower the SNR and force the downshifting in modulation earlier than in less dense environments, like in Qatar or Saudi Arabia. The popular use of low-E glass also degrades the quality of the signal at relatively strong power levels because it causes severe multipath interference, which may confuse the receiver, and forces it to downshift its modulation, and as a result, reduce throughput.

How does the spectrum band impact Wi-Fi’s reach and performance
In addition to standards, Wi-Fi performance is dictated by the spectrum it uses. Wi-Fi 4’s advantage is that it propagates through walls and floors thanks to the use of the 2.4 GHz band, but it is extremely bandwidth-limited, offering only three 20 MHz channels and low throughput. In addition, this band can easily get congested by household appliances and neighboring Wi-Fi networks. Ookla’s data shows that, generally, 2.4 GHz download speed starts to level off at around –40 dBm to –50 dBm across all three countries. It should be noted that for a device to maintain a consistent RSSI, it should move much closer to the CPE when using 6 GHz (and closer with 5 GHz) compared to 2.4 GHz. That is why routers often transmit higher-frequency signals at a higher power level to compensate for the natural range loss.
The 5 GHz band increased the available bandwidth, supporting channel widths of up to 160 MHz, allowing much higher speeds but at reduced range and with lower penetrating capacity compared to 2.4 GHz. In Qatar and the U.A.E., we note an “acceleration point” at RSSI of –35 dBm, where throughput begins to improve rapidly as a device moves toward the router, taking full advantage of the inbound fiber line. At the other end, speed deterioration begins to accelerate sharply at –60 dBm for all countries. Median download speed drops by 44%, 40%, and 33% for the U.A.E., Qatar, and Saudi Arabia, respectively, over 10 dB between –60 dBm and –70 dBm.
The 6 GHz band (introduced in Wi-Fi 6E and Wi-Fi 7) supports wider 320 MHz channels and reduced interference, which pushes performance to multi-gigabit speeds. Ookla’s data show a non-linear relationship between download speed and RSSI, as well as different patterns between countries. For example, in Saudi Arabia and the U.A.E., speed starts to level off when RSSI is above –50 dBm, while in Qatar, it keeps increasing to touch 1.5 Gbps. Wi-Fi over 6 GHz maintains speed above 500 Mbps for Qatar and the U.A.E., even if the RSSI falls below –50 dBm, then speed deterioration accelerates once it crosses -65 dBm. Yet it remains very high (>100 Mbps at –80 dBm). This shows that while 6 GHz is more prone to absorption by physical barriers, its lack of congestion and more advanced modulation efficiency allow it to maintain very high speeds at further distances.

Practical solutions address last-mile bottlenecks in the Gulf region
The growing performance envelopes of modern Wi-Fi technologies and increasing levels of resilience to distance and obstacles underscore the importance of upgrading to modern CPEs. However, users should position routers strategically in the home to maximize efficiency. For example, by placing them in a central location, rather than in a corner, and, if possible, mounting them on a shelf or on the ceiling to avoid obstacles such as furniture. They should also keep them away from large metal objects, mirrors, and household appliances like microwaves that might operate in the 2.4 GHz band.
For large villas and apartments typical of the Gulf, a single router is probably insufficient. That is why a mesh network should be considered, as it extends coverage throughout the home. Most modern construction in the Gulf region is hardwired via Ethernet, which facilitates connecting the mesh nodes, bypassing concrete barriers entirely. Finally, allowing the CPE to dynamically select uncongested channels and activating ‘band steering’, which directs connected devices to the faster, less-crowded 5Ghz/6Ghz radio, can also help.
Local ISPs have also been active in ensuring Wi-Fi performance is optimal by offering mesh extenders during registration or upgrade phase, and deploying Fiber-to-the-Room (FTTR) solutions to provide undegraded gigabit access throughout the home. In addition to installing additional hardware, ISPs can validate Wi-Fi setup and performance at installation (or upgrade) time. In this scenario, a technician would perform an indoor site survey and measure RSSI and throughput (in addition to other parameters such as SNR) to advise homeowners on optimal CPE location. ISPs can also be more proactive and remotely run diagnostics to monitor the health of the home network and provide either guidance to end users on how to fix the problem or offer hardware upgrades.
Optimize CPE placement to bridge the gap between provisioned speed and realized performance
Ookla’s data shows that while high-speed fiber connectivity is widespread in the Gulf region, it is the indoor wireless network and surrounding environments that determine the speed that is experienced by end users.
Over the last two decades, successive enhancements were introduced in Wi-Fi standards, modulation techniques, and antenna design to make Wi-Fi reach new speed highs, support more devices, and be more resilient to interference and signal attenuation. This analysis provided evidence that the performance ‘ceiling’ and ‘breaking points’ were pushed further with every new standard. However, the physics of radio frequency propagation and the diverse architectural constraints of Gulf homes suggest moving away from a one-router, one-size-fits-all approach toward more intelligent router and mesh placement, continuous monitoring, and reconfiguration to ensure that the wireless link is as robust as the fiber optic link that feeds it.
