The function of<br \/>\nlayer 1 is to convey information through the radio frequency<br \/>\nchannel, while contending with various channel impairments such as<br \/>\nnoise, interference, radio multipath, and delay distortion. The<br \/>\ndefinition of layer 1 concentrates on the following subjects:<\/p>\n<p>\u2022 Modulation<\/p>\n<p>\u2022 Pulsed transmission turn-on and turn-off<\/p>\n<p>\u2022 Mechanism for time division multiplexing (TDM)<br \/>\nsynchronization<\/p>\n<p>\u2022 Definition of TDMA frame structure<\/p>\n<p>\u2022 Mechanism for amplitude and phase recovery<\/p>\n<p>\u2022 Radio channel coding<\/p>\n<p>IOTA has been designed to deliver a flexible bit rate in 50,<br \/>\n100, and 150 kHz radio channel bandwidths in the 700 MHz band. This<br \/>\nflexibility allows IOTA to optimize performance by allowing higher<br \/>\nsystem data throughput under good signal conditions while still<br \/>\nsupplying significantly better throughput than current systems<br \/>\nunder weaker signal conditions. The basic mode of operation for<br \/>\nIOTA is time division multiple-access (TDMA). Layer 1 reserves<br \/>\ncertain symbols within the information stream to provide for its<br \/>\noperation.
