    • RE: PSM NB-IoT Timer

      Dear customer,

      In the table below, you will find the latest configuration of the PSM timers (Activity timer T3324 and Extended TAU timer T3412) in the DT NB-IoT networks.
      Note: all parameters provided below are subjected to change and are therefore only indicative and provided without guarantee. This table shall be seen as a snapshot of DT’s network configuration and values may evolve over time.

      As mentioned above, we are currently checking the minimum value for the T3412 timer (reported by users as being set to 2 hours) and will confirm this value asap.

    • RE: LTE-Cat.M1 Rollout in Germany

      @Ronan-Lacroix said in LTE-Cat.M1 Rollout in Germany:

      Hi Alfons, Hi Thomas,

      I have the pleasure to announce that LTE-M is now available in Germany throughout the country.
      Please take a look at https://t-map.telekom.de/tmap2/mobileiot for a detailed view of our coverage map, as well as at https://iot.telekom.com/ for the available pre-paid offerings.

      Looking forward to getting your return of experience on our brand new IoT network!

      Kind regards,

      Ronan

      Hi Stefan,

      A press release should be issued soon, and more information about the network features and benefits will be posted on this forum in the weeks to come.

    • RE: Limited Data Rate after to many messages on aday?

      Hi Timo,

      Those strong delays are most probably a consequence of the weak network signal strength at your test location.

      In CE-Level 2, the device has to repeat the same signal over the radio interface multiple times (up to 2048 repetitions in downlink, and 128 repetitions in uplink!) in order to enhance the link budget and ensure a successful signal transmission.
      This has a direct impact on both the data throughput and the communication latency, which you see reflected in the Ping RTT.

      This can be solved by improving the signal quality, for instance by changing the location of the device or by using a better antenna.

      Best regards,

      Ronan

    • RE: eDRX Support for LTE-M

      eDRX is being deployed as we speak across our German NB-IoT network, and will be enabled in TMNL shortly thereafter.
      We will inform you as soon as it is commercially available there!
      Note that eDRX for NB-IoT is already live nationwide in our Magenta network in Austria.

      eDRX however is not yet available in our LTE-M networks, but we plan to deploy this feature across our LTE-M footprint (currently Germany, Netherlands and Austria) beginning of next year.

      The LTE-M coverage map for Germany is available under: https://t-map-ta.telekom.de/tmap2/mobileiot/.
      LTE-M unfortunately isn’t available in the T-Mobile Czech Republic network yet.

    • RE: eDRX Support for LTE-M

      @inka-O,

      1. As stated above, we will implement eDRX for LTE-M beginning of next year, but we cannot tell you exactly when right now (our current target is Q1 2021). As far as we know, most of the other European LTE-M operators haven’t yet enabled eDRX neither, but also plan to deploy it next year.
      2. eDRX does not exist in 2G, only in LTE, and deployed primarily (if not exclusively) in its Low-Power Wide-Area categories (i.e. LTE-M and NB-IoT).
      3. PSM is supported in all of DT’s LTE-M networks as well as in all of our roaming partner networks. Like eDRX, PSM has only been standardized in LTE networks and is not available for 2G.

      Best regards,

      Ronan

    • RE: SIM7020E has trouble entering PSM

      Hi MeneerJacco,

      You may want to specify the PSM Timer value to be used before entering Power Saving.
      If you want the module to enter PSM right after leaving its connected mode, use for instance the command:

      AT+CPSMS=1,,,,"00000000"
      

      You may also want to provide a longer TAU timer. To configure for instance a TAU Timer of 3 hours and a PSM of 0s, enter:

      AT+CPSMS=1,,,"00100011","00000000"
      

      Best,

      Ronan

    • RE: eDRX Support for LTE-M

      @inka-O , for detailed information about our LTE-M network footprint and the supported features, please check our documentation library: https://docs.iotcreators.com/docs/introduction-to-lte-m.
      You should find an answer to all your questions above! 😉

      All features (e.g. PSM, LP-TAU, eDRX) when deployed are available nationwide.

    • RE: Roaming - local network partners

      @JakubT,

      This essentially depends on your SIM contract and associated tariff. If this tariff includes EU-Roaming for instance, then Roaming in all Roaming Partner networks should be possible, and not only in DT’s own affiliates’ network.
      Best regards,
      Ronan

    • RE: Network time

      @Lauwie007
      I have not tested it myself, but I guess your live test has just proven it, hasn’t it? 😊
      Keep in mind that this time is provided by the local network in which you are actually roaming, so if you’re roaming in say, the Vodafone UK network, this time and associated timezone will be provided by Vodafone UK (if supported as just discussed).
      Kind regards, Ronan

      @Jeroen-van-Bussel
      Please do not quote me on this (I’m not a 3GPP specification expert), but according to 3GPP 24.008, the MM (for Mobility Management) information procedure and information message (which optionally contain the time information) unfortunately are optional in the network (see extracts below from the specification in its release 15).

      Kind regards, Ronan

    • RE: PSM settings with roaming sim card

      Hi @Christian-Jacobsen,

      Full LTE-M Roaming support with EMnify will be implemented in Germany on March 18, 2022. From that date onwards, PSM and Long-Periodic TAU features should be available to you with this SIM-card.
      Availability dates in Austria and other DT networks however aren’t currently available.

      Kind regards, Ronan

    • RE: Network time

      Hi all,

      Please note that network time is now also provided over our LTE-M network in Germany, and can be retrieved with the usual AT commands (e.g. AT+CCLK?, AT+QLTS=2, …)

    • RE: eDRX in LTE-M Network

      @herr-bruns ,
      Hi Mr. Bruns,
      We have started piloting eDRX for LTE-M in parts of our network. If everything runs smoothly, we will deploy the feature nationwide beginning of next year and make it available to all our customers.
      I will inform you as soon as we are done!
      Kind regards,

    • RE: Network time

      @Sven-Brandau ,
      Please note that “network time” has meanwhile been enabled in our NB-IoT network in Germany, so that AT command “AT+CCLK?” should no longer return an error.
      Kind regards,

    • RE: eDRX in LTE-M Network

      Dear Mr. Bruns,
      The eDRX feature unfortunately isn’t yet available in our German network but its nationwide deployment is in preparation. I will gladly inform you via this post as soon as it is done.
      If it can help (for test purpose), eDRX has already been enabled in Austria in our Magenta Telekom network and is being rolled out as we speak in our T-Mobile Netherlands network.
