27、 Foreword - Supplementary information The committee responsible for this document is ISO/IEC JTC 1, Information technology, SC 6, Telecommunications and information exchange between systems. This second edition cancels and replaces the first edition (ISO/IEC 29157:2010), which has been technically r
28、evised.vi ISO/IEC 2015 All rights reserved ISO/IEC 29157:2015(E) Introduction This International Standard is the revision of ISO/IEC 29157 . This International Standard was established to provide a unified platform for services of data rates up to 1 Mbps: control data, voice, audio, and video. The p
29、urpose of the revision is to accommodate the advancement of technology for higher-quality services in the mobile applications. The direction of the revision is three-fold: to enhance throughput, to facilitate co-existence with other technologies such as time-division LTE (long term evolution) and Wi
30、MAX II, and to increase data rate. For the higher throughput, the length of the preamble of the payload frames is made variable up to the users need (see 9.2.2). For the co-existence, the duration of the middle frames is reduced to 4 ms from 16 ms to make align with those of the other technologies (
31、see 8.3). With the shorter middleframes, the International Standard does not only harmonise with other technologies, but also attains advantages of shorter communication delay and less paring time. To increase the data rate, the message part of the payload frames may be modulated with QPSK. The modu
32、lation format is indicated by the PHY version of the header (see Clause 7 and 9.3). With the addition of the new option, the data rate can be increased to 2 Mbps. In addition, to protect communications against security challenges due to the loss of protection provided by wires, this International St
33、andard provides the optional security mechanism (See 9.3.2 and Annex A).

Such applications that require a short-range wireless communication channel can be listed as follows in the order of data rates; video, audio, voice, control, sensor, and so on. A different platf
47、orm for a different application may be an ineffective way in light of cost, time-to-market, compatibility, etc. It would be beneficial to have a single platform which is capable of accommodating all these applications with the least overhead. This International Standard is intended to provide a unif
48、ied yet efficient and versatile platform for low- power, low-data-rate, short-range wireless communication applications. It is possible to accommodate diverse services of different nature in a single platform. For mobile applications, low power consumption is one of the most important factors. To sa
49、ve power, data rate should be traded-off. This International Standard aims for the applications of 2 Mbps or less. To minimise implementation effort, it assumes the use of off-the-shelf RF components for the ISM band. ISO/IEC 2015 All rights reserved 3 ISO/IEC 29157:2015(E) The International Standard makes use of frequency hopping, time-division multiple access, and time/frequency hybrid diversity. Frequency hopping is adopted to render immunity to the channel variations and to pro
