“…Some studies of IEEE802.15.4g already exist. Sum et al [ 13 ] evaluate the performance of a WPAN when using the IEEE802.15.4/4e/4g for SUNs through simulations. Dias et al [ 14 ] deploy a WSN in office/canteen/warehouse buildings in a smart grid application, and evaluate the performance of a single radio setting (O-QPSK, 250 kbps, 2 MHz channel bandwidth).…”

IEEE802.15.4g is a low-power wireless standard initially designed for Smart Utility Networks, i.e., for connecting smart meters. IEEE802.15.4g operates at sub-GHz frequencies to offer 2–3× longer communication range compared to its 2.4 GHz counterpart. Although the standard offers 3 PHYs (Frequncy Shift Keying, Orthogonal Frequency Division Multiplexing and Offset-Quadrature Phase Shift Keying) with numerous configurations, 2-FSK at 50 kbps is the mandatory and most prevalent radio setting used. This article looks at whether IEEE802.15.4g can be used to provide connectivity for outdoor deployments. We conduct range measurements using the totality of the standard (all modulations with all further parametrization) in the 863–870 MHz band, within four scenarios which we believe cover most low-power wireless outdoor applications: line of sight, smart agriculture, urban canyon, and smart metering. We show that there are radio settings that outperform the “2-FSK at 50 kbps” base setting in terms of range, throughput and reliability. Results show that highly reliable communications with data rates up to 800 kbps can be achieved in urban environments at 540 m between nodes, and the longest useful radio link is obtained at 779 m. We discuss how IEEE802.15.4g can be used for outdoor operation, and reduce the number of repeater nodes that need to be placed compared to a 2.4 GHz solution.

“…Documents in [1,9] show the interrelated domains of smart grid/utility and outlining the communications entity in the field area network for SUN. In [2,10], we have recorded extensive and detailed performance evaluation on both the IEEE 802.15.4g frequency shift keying (FSK) and orthogonal frequency division multiplexing (OFDM) PHY layers. Optimization and enhancement on system design were studied in [11][12][13][14].…”

This paper presents the experimental performance evaluation results of the IEEE 802.15.4/4g/4e Smart Utility Networks (SUN) in applications suited for outdoor environment. SUN is an advanced wireless communications network designed for reliable, low data rate, and low energy consumption networks for command-and-control applications like utility service, sensor network, and so on. IEEE 802.15.4g/4e is the international standard for SUN supported by multiple utility providers and product vendors. In this paper, a comprehensive field test was conducted by employing the implementation we have developed to evaluate the performance of the SUN devices based on IEEE 802.15.4/4g/4e standard. The output power of the implementation is 250 mW for extended range, reducible to 20 mW for short-range scalability and battery preservation. Results showed that in an outdoor line-of-sight environment, the achievable one-hop range of a 50 kbps SUN device was 450 m. Next, in a non-line-of-sight environment involving typical residential concrete building, the communications could be established penetrating obstructions to reach above the 11th storey, reaching the performance degradation limits at the 20th storey. Next, the network of the SUN system was proven to be capable of supporting a typical multihop tree network in a dense populated building, meeting the required performance by the standard.

“…Unlike these existing works, this paper presents the design of an experimental OW MIMO system based on which empirical models are derived. Such approach without any theoretical development has been widely adopted in previously published papers in this journal as well as others, to name a few [10][11][12][13][14]. The novelty of this paper includes the design and building of several experimental OW MIMO systems and the derivation of the relationships between BER and distance/ displacement using different modulations by using curve-fitting based on BER measurements.…”
