Most of EU member countries plan to have (by Decision (EU) 2017/899) assigned the 700MHz band (known as APT700 or B28) to mobile operators by June 2020. Therefore, EU is being very positive to this implementation started by the Asia-Pacific Telecommunity.
For example, from what is to be understood (between the lines), Republic of Croatia plans to leave (free up) LTE 700 MHz spectrum by the 30th June of 2020 as it is currently used by its digital terrestrial television (still transmitting 576p, a common “square-pixel” representation of 625/50 PAL/SECAM, under 10-years binding concession agreement). To sum up, coexistence of new services (like IoT) in the 700 MHz band with DTT is (only) possible if DTT is limited from 470 to 694 MHz leaving 703-788 MHz spectrum free for B28 band.
Back to topic, with appropriate firmware support my eventual choice for B28 would be affordable Telit LN941A6-E1 or, if something better needed, Telit LN940A11/LN940A9. @Torrone, yes, for L5 developer board Quectel EG25-G module (Qualcomm MDM9207 Cortex A7 @1.3GHz running Linux kernel) looks promising (including B28 and VoLTE) and good testing choice with Mini PCIe form factor, just like Simcom SIM7100E-PCIE (Qualcomm MDM9215). Price for Quectel EG25GGB-MINIPCIE-S of around 50.00 EUR looks acceptable as well, yet firmware might be questionable, I don’t know. Anyway @36w4r6, I can certainly cope with the fact that Quectel EM20 module for 699.00 USD is not something I need.
