“…The modulation guarantees an adaptive data rate for fluctuating channel, high order modulation for low bit error probability can increase data rate [233]. In [234], it is possible to reach 100Gbps using 16-QAM optical modulation and BER equal to 10 −3 and using UTC-PD source for heterodyning; coding helps to reduce errors. MAC layer can be designed to support variable throughputs and fits frame length to channel conditions via information from the physical layer.…”

Terahertz communication is emerging as a future technology to support Terabits per second link with highlighting features as high throughput and negligible latency. However, the unique features of the Terahertz band such as high path loss, scattering, and reflection pose new challenges and results in short communication distance. The antenna directionality, in turn, is required to enhance the communication distance and to overcome the high path loss. However, these features in combine negate the use of traditional medium access protocols (MAC). Therefore, novel MAC protocol designs are required to fully exploit their potential benefits including efficient channel access, control message exchange, link establishment, mobility management, and line-of-sight blockage mitigation. An in-depth survey of Terahertz MAC protocols is presented in this paper. The paper highlights the key features of the Terahertz band which should be considered while designing an efficient Terahertz MAC protocol, and the decisions which if taken at Terahertz MAC layer can enhance the network performance. Different Terahertz applications at macro and nano scales are highlighted with design requirements for their MAC protocols. The MAC protocol design issues and considerations are highlighted. Further, the existing MAC protocols are also classified based on network topology, channel access mechanisms, and link establishment strategies as Transmitter and Receiver initiated communication. Open challenges and future research directions on Terahertz MAC protocols are also highlighted.

I. INTRODUCTION T HE DEMAND for wireless data traffic has increased significantly since the evolution of Internet and Mobile Technology and is projected to exceed Petabytes by 2021 [1].

“…1 In addition, in comparison to free-space (FS) optical links, subTHz links are much less affected by atmospheric turbulences 2 and visibility-limiting weather conditions such as fog 3 , snow 4 and haze. 5 In the past few years, several wireless transmission links with line-rates equal or higher than 100 Gbit/s [6][7][8][9][10][11][12][13][14][15][16][17] have been demonstrated, at distances of up to 110 m. 15 At the transmitter side, most of these successful high-bit rate transmission schemes rely on photonic-based direct optical-to-RF conversion by means of a uni-traveling carrier (UTC) photodiode 18,19 . However, at the receiver side, electrical down-mixing of the subTHz signal to baseband or an intermediate frequency (IF) is typically performed.…”

The first transparent Optical-subTHz-Optical link providing record-high line-rates of 240 and 190 Gbit/s over distances from 5 to 115 m was recently demonstrated. The link has been based on a direct data-conversion from optical to subTHz using a > 500 GHz plasmonic Mach-Zehnder modulator. We discuss the potential of plasmonic devices in subTHz wireless links to efficiently bridge optical fiber networks.
