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). |
