“…What is missing is work that evaluates IEEE802.15.4g OFDM experimentally, and assesses its suitability for lowpower wireless mesh-based Smart Building solutions. Lee et al [18] are, to the best of our knowledge, the only authors who have done a similar study, on a home-made implementation of IEEE802.15.4g OFDM (combining a 32-bit micro-controller, an FPGA and a radio frequency ASIC). Their article is, however, focused on the feasibility of a smart home utility service using IEEE802.15.4g FSK and OFDM.…”

This paper compares the performance of two IEEE802.15.4 physical layers in the Smart Building context: 2.4 GHz O-QPSK and sub-GHz OFDM. The former has been in the IEEE802.15.4 standard since 2003, the latter was rolled into its 2015 revision. OFDM promises exceptional performance, in particular in environments with high external interference and multi-path fading. This paper starts with a comprehensive overview of IEEE802.15.4 and IEEE802.15.4g, with a particular focus on OFDM, its design drivers and modes of operation. The second half of this paper presents results from an exhaustive benchmarking campaign of both technologies in a building environment, and discusses lessons learnt. We show how OFDM has a higher range, even at 400 kbps and 800 kbps data rates. We then quantify the importance of frequency repetition in OFDM, and of using a wide communication channel, and we show how the use of OFDM can result in a 2-4× decrease in power consumption compared to 2.4 GHz O-QPSK. We conclude by recommending the use of OFDM option 1, with MCS2 for short (<128 B) frames, and MCS3 otherwise.

Since its 2015 revision, IEEE802.15.4 now supports the OFDM physical layer at 2.4 GHz, on top of the popular O-QPSK modulation. Chips capable of both O-QPSK and OFDM are currently available. The question now is whether OFDM is relevant for low-power wireless mesh networking; given its prevalence in 4G cellular, it could be a game-changer. We start by collecting a comprehensive connectivity dataset, 141,587,000 data points, continuously over 21 days. We then show, in an entirely counter-intuitive manner, that OFDM alone is not enough to cope with external interference and multi-path fading, and we recommend combining OFDM with channel hopping at the link layer. In the presence of WiFi interference, we further recommend using OFDM option 1 MCS3, a fast 800 kbps mode, which does not use frequency repetition, even though the latter is meant to increase frequency diversity.
