    簡報者 簡報註解 Predictions for the internet of things are quite huge

    Traditional smartphone, PC and tablet shipments will continue to be strong but growth has flattened

    Much of the future growth for the electronics industry is linked to IoT

    Many companies are reorganizing themselves to focus on IoT and making commitments about the connectivity of their future products

    each message is up to 12 bytes • Low power: Up to 20 years of battery life • Long range – up to 30 miles in rural area

    and 2-6 miles in urban area – Devices require a SIGFOX modem and SIGFOX

    network – Target applications: smart meter, pet tracking,

    SIGFOX

    簡報者 簡報註解 SIGFOX is a startup in France building a low cost network dedicated for IoT (low throughput). They are putting out their own infrastructure, not leasing from other operators. They claim they can cover a city by 1/100 of base station for example a Tier-1 operator needs. You can think of this as a competitor to current cellular network but only focused on IoT/M2M. It is the 1st and only network fully dedicated for IoT/M2M.

    Spectrum is huge cost for operators so SIGFOX uses sub-GHz unlicensed spectrum and patented ultra narrow band (UNB) communication.

    Ultra low throughput - ~100 bps. Device can send between 0 and 140 messages per day, each message is up to 12 bytes. Unlike cellular networks, SIGFOX network is not for mobile communication, but for ultra low rate devices such as sensors, smart meters, smoke detectors etc. Smart meter is biggest application for IoT. According to SIGFOX spokes person, “600,000 smart meter connected to network = 1 person watching Netflix”. For example, SIGFOX will not work for connected car. Connected car would require cellular because of broadband data – to download google map etc… Ultra high energy efficiency - Up to 20 years of battery life. Radios go to sleep when not transmitting. 12 byte is the limit to transmit, battery life is very long. Long range – up to 30 miles in rural area and 2-6 miles in urban area

    Devices require a SIGFOX modem to connect to SIGFOX network. Target applications: smart meter, pet tracking, smoke detector, agriculture etc…

    Example of current use case with insurance company. Connected smoke detector. Insurance company gave their customer a connected smoke detector. As long as the connected smoke detector is sending back messages, once per day saying it is operating correctly, customer gets discount on home insurance.

    SIGFOX networks deployed in France, Netherlands, Russia and Spain; Launching 902 MHz network in San Francisco

    Technology Trade-offs

    Pros: • Long range • Long battery life

    (>10 years) • Low cost • Uses cellular

    network as backhaul

    Cons: • New standard • Unlicensed band -

    interference • Very low data rate –

    can only be used for IoT

    Pros: • Well established

    standards • Long rage • High data rate • Very wide coverage • Licensed band (except

    LTE-U)

    Cons: • Not optimized for IoT

    • Battery life • Cost

    Pros: • Long range • Long battery life (up

    to 20 years) • Low cost

    Cons: • New standard • Unlicensed band -

    interference • Can’t run on existing

    cellular network – needs a dedicated SIGFOX network

    • Very low data rate - can only be used for IoT

    GTI 2.0啟航 加速推動LTE應用服務與擴大 LTE-A Pro發展資源為其重要的工作目標

    VoLTE RCS

    推動 TDD 4G Plus技術過渡到 5G世代

    推動NB-IoT 於2017年實 現商用化

    資料來源:DIGITIMES,2016/3

    簡報者 簡報註解 推動TD-LTE網路標準國際化的組織GTI(Global TD-LTE Initiative)於2016年MWC會場宣布,由於全球4G LTE市場中,TD-LTE已達到76個商用網路、4.7億用戶、140萬個基地台及逾2,650款終端設備等目標,代表將TD-LTE標準推上國際舞台的階段性目標已完成,因此啟動GTI 2.0發展新階段。 GTI 2.0主要發展目標: 加速推動VoLTE/RCS等4G應用服務發展,會中中國移動發表3款支援VoLTE的中低價位自有品牌智慧手機A1s、N2、A2,及三星J系列與A系列的VoLTE定製機。 推動4G TDD標準過渡到5G網路世代,確保TD-LTE在技術演進的過程中保持重要位置,並獲得足夠的產業發展資源(如頻譜分配) 。 布局NB-IoT物聯網產業,會中宣布中國移動將加速推動公共物聯網於2016年底試用,2017年實現商用化目標。 DIGITIMES Research觀察,GTI從成立之初即是作為推動TD-LTE產業鏈成長而存在,然面向4.5G/5G世代TD-LTE與FD-LTE標準將趨於融合,GTI 2.0更像是中國移動的發展目標而非著眼全球戰略的國際標準推動組織,未來的發展定位恐需要更明確的方向。
