This document describes the technical requirements to define a wireless switched point-to-point physical layer to IEEE Std. 802.15.3 operating at a nominal PHY data rate of 100 Gbps with fallbacks to lower data rates as needed. Operation is considered in bands from 252 GHz to 325 GHz. Additionally, the technical requirements for modifications to the Medium Access Control (MAC) layer, needed to support this new physical layer, are defined. The requirements in terms of transmission ranges depends on the specific use cases defined in the applications requirements document [4] and spans a range of 3 cm to 200m. The required Bit error rates at the PHY_SAP depend also on the defined use cases and span a range from 10-6 to 10-12. The proposals shall also comply with the regulatory requirements taking into account the specific situation for carrier frequencies beyond 275 GHz as defined in the radio regulations [9]. Topology and Link Switching This clause identifies operational topologies In all use cases the topology will be point-to-point (P2P) and limited to two active devices. Each of the devices will contain both a transmitter and receiver and is thefore denoted as a transceiver (TRX). It may be necessary to switch between several links, see Figure 7.1. The possibility for link switching between two connections is mandatory. Link switching during a running connection is optional. Obviously this is use case dependent since for some use cases link switching may not be appropriate. Figure 7.1: Switched Point-to-Point Links; Link 1 TRX1 to TRX2 switched to link 2 TRX1 to TRX 3 Data Rates The data rates shall be sufficient to support the proposed use cases in conjunction with the operational frequency plan and channel model. This section discusses the data rates, which usually is the basis for different PHY type classes. The PHY shall at least support the data rates as defined in Table 8.1. For better compatibility with Ethernet a data rate of 40 Gbps may be considered as well Table 8.1: Data Rates for different use cases Use case Minimum Data Rate Required Data Rate Required BER in Gb/s in Gb/s at the after error higher end correction at PHY-SAP
