TechInsights recently explored and compared some of the main Blueta and Honeycomb applications in the market, which are expected to continue to dominate the Internet of Things market for a while.
Bluetooth 5.0 SOC will be quickly used by consumer networked devices, such as smart watches, health and fitness products, etc. Two emerging honeycomb netbook standards - Narrow Band IoT (NB-IOT) and Enhanced Machine Communication (EMTC), under the promotion of operations, will also be used in smart meters, bicycles and other emerging applications .
The Internet of Things devices include some of today's most advanced chips. As the same network itself, the underlying technology is also rapidly developed.
According to TechInsight's dismantling and analysis of dozens of Internet of IoT devices in various industries, it is clear that Bluetooth will continue to be one of the main technologies used in SOC. The latest version of Bluetooth 5.0 is quickly replacing earlier versions. The Bluetooth 5.0 released in 2016 extends 4 times, while the transmission rate is doubled, and the amount of data transmission of the SOC is added.
Through comparative analysis, SOCs often used in many products include DA14580, Nordic Semiconductor of Daile Semiconductor, and Bluenrg of STMicroelectronics. In general, these Internet of Things SOC integrates in a single chip, including CPU core, power management chip (PMIC), memory, and RF (RF) transceivers.

System level package (SIP) is another solution for many Internet of Things devices. For example, MT2523G Bluetooth SIP design includes Bluetooth SOC, PMIC, Memory, and GNSS receivers. 6 chips are integrated in a single package. This high integration and SIP on a single chip will continue to promote future Bluetooth network SOC design.

3GPP recently released Release 13 included two LTE-based Internet of Things technology - NB-IOT and EMTC. Including global operators such as AT & T, China Mobile (China Unicom) and Verizon, etc. have launched NB-IOT testing networks or formulate relevant development plans. NB-IOT is expected to be used in applications such as smart cities, public meters and industries. One of the other emerging applications is May 2017, Qualcomm announced the plan with China Mobile and Mobike bicycles (MOBIKE). The three-party cooperative test plan will use a high-pass MDM9206 modem to identify the available bicycles.

For Ofo growing bike fleets, the smart lock implemented using NB-IoT is one of the most conspicuous honeycomb applications. The use of NB-IOT eliminates the trouble of waiting for the consumer card in the waiting for the consumer card due to insufficient capacity. China Telecom pointed out that the low-power NB-IOT chip used by the smart lock means that the battery life will last for 8 years to 10 years, which means that the battery will never need to replace the battery in the standard life cycle of the OFO bike.
China Telecom launched NB-IoT networks in May 2017, covers 95% nationwide, and released the NB-IOT service in June. The NB-IoT network deployed in the 800 MHz band provides indoor and outdoor coverage, and a base station can support 100,000 devices within 2.5 square kilometers.
QUECTEL honeycomb networked module
For the analysis of the two QueCtel NB-IOT modules - BG96 and BC95, both use high integrated SOCs. The BG96 uses Qualcomm Supports EMTC and NB-IOT MDM9206 modem chip and is used with Qualcomm's WTR2965 RF transceiver.

BC95 module Based on the British NET NEUL's modem chip - Huawei, after $ 25 million in September 2014, NEUL is already a part of Hisilicon. This NB-IoT SOC called Boudica 120 integrates modem, RF transceiver, PMIC, and memory, and supports 3GPP Release 13.
