Physical layer Clause Samples
The Physical Layer clause defines the responsibilities and standards related to the physical infrastructure used for data transmission, such as cables, connectors, and hardware interfaces. It typically outlines the types of physical media permitted, installation requirements, and maintenance obligations for the parties involved. By specifying these details, the clause ensures compatibility and reliability in the physical components of a network, reducing the risk of technical failures and disputes over infrastructure quality.
Physical layer. The physical layer of the Internet FWA air interface uses digital time division multiplex/time division multiple access (TDM/TDMA) with a 10-slot frame structure. Uplink and downlink carriers are paired, and separated by a fixed duplex spacing of 99.84MHz. A TDM/TDMA channel (i.e. one time-slot one on one RF carrier) is known as a physical channel. In the maximum configuration, one ITS provides 18 pairs of RF carriers, and 180 physical channels. The uplink carriers are contained within the frequency band 3425 MHz to 3450 MHz, and the downlink carriers are contained within the frequency band 3525 MHz to 3550 MHz. The modulation scheme for both the uplink and downlink direction is pi/4 shifted differential quadrature phase shift keying ((pi)/4DQPSK) with a nominal symbol rate of [ * ] symbols/s. The gross data rate is [ * ] kbits/s per carrier.

Physical layer. The first layer of the seven-layer International Standards Organization (ISO) Open Systems Interconnect (OSI) reference model. This provides the mechanical, electrical, functional and procedural characteristics required to gain access to the transmission medium (e.g., cable) and is responsible for transporting binary information between computerized systems.
