“…L wall is set to zero and F M to 28 dB to assure maximum link outage at 0. [64]. A large single-cell coverage area (0.43 square km) is reported at 1 Mbps and drops gradually to 0.36 square km at 2 Mbps with further decreases in the coverage area for increasing bandwidth.…”

“…Ting et al, [64] performed an insightful study on the use of IEEE 802.11n WLANs for multi-hop networks as the backhaul link in Malaysia's rural areas. Their study focused on maximizing the coverage and backhaul distance of IEEE 802.11n WLAN to enable various applications, e.g., to provide basic telephony access, Internet broadband connection, and community information access.…”

“…A reason for this lack of coverage is that user locations are primarily beside streets, harbors, rivers, etc. The authors in [64] reported that a maximal coverage of IEEE 802.11n with 4 spatial streams (SS) can reach up to 800 m at 50 Mbps with the use of directional antennae of 15 dB gain, which is appropriate for the back-haul link. The use of an antenna with 3 dB gain only lead to coverage of 400 m at 50 Mbps, which is appropriate for access links for mobile users.…”

“…Harsh weather conditions are more likely to damage the energy supply (solar panels, power regulators), e.g., due to thunderstorms or heavy snowfalls. Increasing the backhaul distance is more suited for rural environments with low user density, whereas maximizing the coverage area is more suited for sub-urban or urban deployment scenarios [64].…”

“…TDMA schemes are beneficial in longrange networks, but not in mesh-networks, due to lack of time synchronization among multiple hops [68]. The use of a larger number of spatial streams (MIMO) is beneficial to increase the coverage [64]. 2-stream works well for high MCS rates and long range ≤ 1800 m, whereas 3-stream only works at low MCS rate and short distances ≤ 300 m [62].…”

Several service applications have been reported by many, who proposed the use of wireless LANs (WLANs) over a wide variety of outdoor deployments. In particular, the upcoming IEEE 802.11ah WLAN protocol will enable a longer transmission range between WLAN access points (APs) and stations (STAs) up to multiple kilometers using carrier frequencies at 900 MHz. However, limitations of WLAN outdoor installations have been found of the plethora of WLAN protocols in experimental studies. This article summarizes the challenges and provides a comprehensive overview of suggested improvements. As the standardization of the IEEE 802.11ah is reaching its final stage, important protocol aspects as well as new features are to be outlined. Interference problems and issues with the WLAN configuration, the physical layer (PHY), and media access control (MAC) are of paramount importance in outdoor WLAN networks; thus, are discussed in detail. Further, we examine the reported upper boundaries in throughput and link reliability of long-range WLANs in different environments, including seasurfaces, unmanned aerial vehicles (UAVs) and tunnels. At the end of this study, we reflect on the major issues regarding sub-1 GHz (S1G) WLANs and propose avenues for further research.Index Terms-WLAN, IEEE 802.11ah, wireless sensor, sub-1 GHz, long-range, outdoor.

Since the inception of Wireless Local Area Networks (WLANs) in the year 1997, it has tremendously grown in the last few years. IEEE 802.11 is popularly known as WLAN. To provide the last mile wireless broadband connectivity to users, IEEE 802.11 is enriched with IEEE 802.11a, IEEE 802.11b and IEEE 802.11g. More recently, IEEE 802.11n, IEEE 802.11ac and IEEE 802.11ad are introduced with enhancements to the physical (PHY) layer and medium access control (MAC) sublayer to provide much higher data rates and thus these amendments are called High Throughput WLANs (HT-WLANs). In IEEE 802.11n, the data rate has increased up to 600 Mbps, whereas IEEE 802.11ac/ad is expected to support a maximum throughput of 1 to 7 Gbps over wireless media. For both standards, PHY is enhanced with multiple-input multiple-output (MIMO) antenna technologies, channel bonding, short guard intervals (SGI), enhanced modulation and coding schemes (MCS). At the same time, MAC layer overhead is reduced by introducing frame aggregation and block acknowledgement technologies. However, existing studies reveal that although PHY and MAC enhancements promise to improve physical data rate significantly, they yield negative impact over upper layer protocols -mainly for reliable end-to-end transport/application layer protocols. As a consequence, a large number of schools have focused researches on HT-WLANs to improve the coordination among PHY/MAC and upper layer protocols and thus, boost up the performance benefit. In this survey, we discuss the impact of enhancements of PHY/MAC layer in HT-WLANs over transport/application layer protocols. Several measures have been reported in the literature that boost up data rate of WLANs and use aforesaid enhancements effectively for performance benefit of end-to-end protocols. We also point out limitations of existing researches and list down different open challenges that can be explored for the development of next generation HT-WLAN technologies.
