  • Probably worthwhile to mention that NB-IoT in Rel. 13 menas the new category Cat-NB1 and eMTC in Rel.13 Cat M1, in Rel. we will most probably see the new categories Cat-NB2 and Cat-M2

  5. 5. 5Radisys Corporation - CONFIDENTIAL What’s in Common • Licensed spectrum (LTE) • Low Power • GPS • Small size • Security • Low cost • Multi frequency band support • Deployments expected to start in H1 2017 • Ongoing trial and limited roll outs • Targets • Smart Cities • Asset Management • Industrial Enterprise • Wearables Source: u-blox, Sequans
  6. 6. 6Radisys Corporation - CONFIDENTIAL Few Technology Considerations (Challenges) • Low cost, low power consumption and long range are key advantages • But low complexity, which is needed to bring down module / device costs, has been achieved via trade-offs: 1. Due to limited downlink capacity, NB IoT is planned to only acknowledge 50% of messages serviced by the wireless technology • design (found in 3GPP Specification TR45.820) NB-IoT • If more messages are acknowledged then the capacity will be hit harder • Can this work for all use cases (say critical medical sensors) if 100% acknowledgement is bypassed 2. Delay and latency caused by the buffering of messages and data in what is called transmit packet aggregation • The 3GPP capacity specifications rely on bundling periodic reports into a single larger transmission, which cellular technology needs in order to handle communication transactions efficiently
  7. 7. 7Radisys Corporation - CONFIDENTIAL Cat-M1 Overview: Salient Technology Aspects • 3GPP releases 10, 11 and 12 have addressed specific requirements for MTC (Machine Type Communications). Cat-1 is a low performance LTE device but not particularly optimized for MTC. Cat-0 is the first device targeted towards MTC. Cat-0 devices are designed for low cost and low power consumption. • 3GPP release 13 has introduced eMTC (enhanced MTC) or LTE-M or Category M or Cat-M1 which includes additional cost reduction measures, especially lower bandwidths in the uplink and downlink, lower data rates and reduced transmit power. • The design goals for Cat-M1 devices are low cost, enhanced coverage and extended device battery life. • The key changes that are incorporated for Cat-M1 are as follows. • Cat-M1 UEs transmit or receive only over a narrow band of 6 RBs. This is to lower device cost. A cell can however support other category UEs over wider BW. • The first few symbols for control information transmission are not applicable for Cat-M UEs. Since Cat-M1 UEs can only read 6 RBs, whereas control region is spread across entire BW. • MPDCCH instead of PDCCH is used for Cat-M1 devices. MPDCCH is similar to EPDCCH albeit with repetitions. • Cross sub frame scheduling. MPDCCH and PDSCH/PUSCH are on different sub frames. • Option for repeating transmissions to meet coverage requirements. IoT devices are expected to be located in deep indoors with poor coverage. CEMode_B UEs are expected to have very poor coverage compared to CEMode_A, and hence would require high number of TX repetitions. • Enhanced DRX to enable configuring Cat-M1 device beyond the previous upper limit or 2.56 sec. This will extend battery life of device to many years. In addition Rel-12 PSM (Power Saving Mode) will also extend the battery life of devices.
  8. 8. 8Radisys Corporation - CONFIDENTIAL CAT M1 Deployments • Verizon • According to Chris Schmidt, executive director, device technology at Verizon Labs, the company hasn’t revealed the specific markets where CAT-M is available, but it is working with potential customers and expects to soon have a CAT-M customer deployment. • The company is on track to have CAT-M available nationwide by end of first quarter 2017. • Interestingly, Schmidt said one use case for CAT-M that is attracting some attention is voice (VoLTE). • He said that security companies are looking at using CAT-M to deliver voice capability in certain security scenarios. For example, with a home security system it may be easier to communicate with the homeowner via voice instead of data. • However, Schmidt added that CAT-M isn’t being eyed as a technology for regular voice conversations. “It’s something we want to trial,” he said, noting that the company will test it during the first half of next year. • Other operators are beginning to trial the technology • AT&T is piloting CAT-M in San Francisco • KPN in the Netherlands just completed a trial of CAT-M using equipment from Qualcomm and Ericsson • Ericsson demo at CES • A fleet management application and shows a truck with sensors measuring conditions on the truck such as door ajar, accident notification, and temperature onboard Source: Verizon, Ericsson, Qualcomm, AT&T, KPN
  9. 9. 9Radisys Corporation - CONFIDENTIAL NB-IoT Overview: Salient Technology Aspects • Narrow band support of 180 kHz • To lower the hardware costs, NB devices will only operate on a very narrow 180 KHz spectrum. • Single tone with 15 kHz and/or 3.75 kHz and Multi with 15 kHz subcarriers • Power efficiency is extremely important for NB devices. To aid longer battery life, UL transmissions are in units of sub- carriers instead of Resource Block. • New Physical channels, NPSS, NSSS, NPBCH, NPDCCH, NPDSCH, NPUSCH, NPRACH • Completely new set of Physical channels optimized for NB Radio transmissions. • Cross sub-frame scheduling • NB devices are latency insensitive and are limited in terms of bandwidth. Hence one NPDSCH/NPUSCH transmission can span across multiple sub frames and NPDCCH and the corresponding NPDSCH/NPUSCH are transmitted in different sub frames. • Repetitions for coverage enhancement • Unlike traditional LTE networks, cellular IoT has higher coverage requirements. Transmissions with repetitions (up to 2048) enhances network coverage to NB devices located in deep indoors. • Mandatory Control Plane CIoT optimization • Data is directly sent over NAS without AS security/Header Comp. Limited RRC procedures. • Optional User Plane CIoT optimization • RRC Suspend/Resume procedures to reduce signaling overhead for Idle-Connected state transitions.
  10. 10. 10Radisys Corporation - CONFIDENTIAL Deutsche Telecom NB IoT Update • As the first company to push NarrowBand-IoT across Europe, we are proud to provide further evidence of Deutsche Telekom's technology leadership,” says Claudia Nemat, Board Member for Technology and Innovation at Deutsche Telekom. • Base station upgrade to support NarrowBand-IoT using the 900MHz and 800MHz frequency. • In Germany, Deutsche Telekom will commercially launch NB-IoT in the second quarter of 2017, and already runs several pilots with large customers in the areas of smart metering, smart parking and asset tracking. • In the Netherlands, the nationwide implementation of the NB-IoT network is scheduled to be completed in 2017 with several customers, Source: DT
  11. 11. 11Radisys Corporation - CONFIDENTIAL Vodafone NB-IoT Deployment in Spain • Valencia and Madrid are the first cities in Spain with NB-IoT. • As part of a nationwide roll-out, we will extend coverage to Barcelona, Bilbao, Málaga and Seville by the end of March 2017, when there will be over 1,000 mobile sites supporting NB-IoT. • Every NB-IoT mobile site can connect more than 100,000 devices. • Our Spanish NB-IoT network was deployed within existing 800 MHz spectrum. • That is the optimal use of Vodafone Spain’s 4G spectrum and will maximise the signal strength and coverage.
