無線物聯網LTE MTC/eMTC ,NB-IoT認證測試

一、物聯網發展趨勢

  NB-IoT是基于移動通信網絡的物聯網技術體系,具有廣覆蓋、大連接、低功耗、低成本的優勢,解決了傳統物聯網存在的技術碎片化、覆蓋不足的問題,極大提升了物聯網的應用能力,獲得了業內的廣泛支持,將成為物聯網主流技術。

   目前,全球多個運營商緊跟NB-IoT發展步伐,在標準協議完成之后第一時間進行技術驗證、測試和商用部署。根據GSA統計,截至2019年1月中旬,全球45個國家/地區的78家運營商正式商用NB-IoT網絡,網絡數量是去年同期的兩倍。

 

二、物聯網的應用以及技術標準要求

In Release-14 3GPP is enhancing the above technologies

• Positioning enhancements [eMTC, NB-IOT, EC-GSM-IOT]

• Multicast, mobility enhancements for [eMTC, NB-IOT]

• New power classes, access/paging enhancements [NB-IOT]

• Higher data rates and VoLTEsupport for [eMTC]

Standalone mode

• A frequency separation of 200 kHz or more between the standalone NB-IoT channel edge of one network and the UMTS/LTE channel edge of the neighbouring  network.

• A frequency separation of 200 kHz or more between the standalone NB-IoT channel edge of one network and  the  GSM  channel  

edge  of  the  neighbouring network.

In-band mode

• No specific requirements in addition to LTE (note 2) and the 

applicable harmonised standards

Guard band mode

• A frequency separation of 200 kHz or more between the NB-IoT 

channel edge and the edge of the operator's block, taking into 

account existing guard bands between operators' block edges or 

the edge ofthe operating band (adjacent to other services).

Note 1: Frequency separation requirements on GSM as defined in ECC Report 266 [14]

Note 2: Frequency separation requirements on LTE as defined in ECC Report 266 [14]
