A, semiconductor news
1. Qualcomm deny new flagship 820 chip fever. On rumors of a new generation of flagship chip 820 still fever serious talk, yesterday, qualcomm shall be publicly denied that. Qualcomm last generation flagship chip Xiao dragon 810 fever it is undeniable that there is a serious, many mobile phone companies flagship model is therefore affected, even some phones have to use frequency reduction Xiao dragon 810 chip to control the temperature. Last year, qualcomm has released a new generation of flagship chip Xiao dragon 820, which has solved the problem of the fever. Starting this year, carrying Xiao dragon mobile phone chip 820 are listed. However, recent news, said Xiao dragon 820 hot problems are still serious.

The system is based on cloud computing for unmanned aerial vehicle (uav) regulation, cover 1500 metres below all helicopters, drone aircraft such as low level monitoring. The validity of the approval document of approval for its trial run for two years, on March 4, 2016 to March 3, 2018.
International standards organization released 3 GPP plan in June of this year to freeze and narrowband Internet of things based on cellular network technology standard NB - IoT. Post standard, as the dominant party of huawei haisi pushing rushed at the end of September this year the NB - IoT commercial chips, this will be the first formal commercial NB - IoT chip, and their prices to the short distance communication chip prices close to. Everything connected to achieve added a big tool, Internet popularization steps to accelerate.
NB - IoT is a kind of innovative technology, so to speak. It supports mass connection, have the depth of coverage, low power consumption, the inherent advantages make it very suitable for sensing, measurement, monitoring and other Internet applications, suitable for smart meters, smart parking, vehicle tracking, logistics monitoring, wear ecological-economic wisdom and intelligence, wisdom, family, intelligence community, and so on. These areas of wide coverage, low power consumption and low cost requirements are very clear, now widely commercial 2 g / 3 g / 4 g and other wireless technologies are unable to meet these challenges.
Many people take it with wi-fi, bluetooth and Zigbee wireless technology, but wi-fi, bluetooth, Zigbee for short Internet applications, and NB - IoT is long wan communications technology, between the two is not a level, there is no comparable. The world of the Internet of things can't be a standard farmland, coexistence of short distance with a variety of long distance communication technology is the most reasonable and best means of solving the problem, and NB - IoT is a long one of the best content of technology.
NB - a IoT advantage: mass connection. NB - IoT than 2 g / 3 g / 4 g is 50 ~ 100 times the uplink capacity increasing, and what this means is that in the case of the same base station, NB - IoT can offer 50 ~ 100 times than the existing wireless access number. A simple example, covered with a base station to a network, using the existing wireless network can only support five terminal access in every family, May 4 phones, 1 tablet was filled, so after all sorts of intelligent home appliances and many sensing devices need to be connected to the Internet can be difficult to access. And NB - IoT at least 50 times the access number is 250 for terminal access, enough to meet the demand of future wisdom a large number of devices connected to the Internet in the family.
Advantage 2: depth of cover. NB - IoT than LTE increases 20 db gain, improved 100 times is equivalent to transmission power, namely coverage increased 100 times, even in the underground garage, basement, underground pipelines can cover signal is difficult to reach. Use of this advantage, vodafone NB - IoT test agency is to carry out the instructions of underground garage project. In navigation and positioning system in the underground garage is local area wireless technology such as network build need WiFi, bluetooth support, the network is limited to the parking lot to use navigation instructions. If you use the depth of coverage of NB - IoT network, only external positioning module, and can build cross-regional parking instructions and navigation.
Advantage 3: ultra-low power consumption. Low power consumption characteristics is an important indicator of the Internet of things application especially for some equipment and occasions, often can't change the battery placed in mountain wilderness in remote areas, all kinds of sensor monitoring equipment they cannot like smart phone recharge from day to day, years of battery life is the most essential requirements. Was not under the premise of make a breakthrough in battery technology can only reduce the power consumption of the equipment to extend battery life.
Communications equipment energy consumption is often associated with the data volume or rate, per unit of time to send packet size determines the size of the power consumption. Small amount of data and equipment of modem and power amplifier can be transferred to the very small level. NB - IoT is focused on the small data quantity, small rate application, so NB - IoT devices can do very little power consumption. In addition, in order to further reduce the power consumption, extend battery life, NB - IoT introduced the super long DRX (discontinuous receiving) power-saving technology and PSM power saving modes. NB - IoT can equipment always online, but by reducing unnecessary signaling and in the state of PSM not accept paging information to achieve energy saving purpose. So we can guarantee the service life of battery more than 5 years.

Graph: NB - IoT introduced the super long DRX (discontinuous receiving) power-saving technology and PSM power-saving modes to reduce power consumption
Four advantages: low cost. Low rate, low power consumption of low bandwidth is low cost advantage. Don't need big cache rate is low, so small can cache, low DSP configuration; Low power consumption, low mean RF design requirements, small PA can achieve; Because of the low bandwidth, don't complicated equalization algorithm... These factors make NB - IoT can do a small chip. Often cost and chip size, the smaller size, lower cost, the cost of the module is lower.

Haisi reportedly launch NB - IoT chip in the size of a coin size integration within the BB and the AP, Flash and battery management, reserve and sensor integration capabilities. AP include three ARM - M0 kernel, each M0 kernel is responsible for the application, security, communication function and so on for functional management to reduce cost and power consumption at the same time, the subsequent chips will integrate Soft SIM, further reduce the cost.
Advantage five: stable and reliable. NB - IoT directly deployed in GSM network, UMTS network or LTE network, with the existing network base station can be reuse in order to reduce the deployment cost and achieve a smooth upgrade, but use a separate 180 KHZ frequency, do not take up the voice and data of the existing network bandwidth, traditional business and the Internet of things in the future business may be done at the same time, stable and reliable. Intelligent meter application, for example, and adopting PLC cable meter reading data recovery success rate at about 60%, compared to NB - IoT can ensure that data recovery rate was 99%, and the success greatly increased reliability.

Yesterday, qualcomm said in a statement, "we have confidence in Xiao dragon 820, its performance and thermal efficiency is fully in line with expectations, performance is very good. We haven't received any report from partners showed its product affected by Xiao dragon 820 processor to produce any thermal efficiency or performance issues." It is no wonder that qualcomm try so hard, because 810 hot issues, qualcomm pursuing opportunities in the high-end market to rivals, especially huawei haisi take up the chip.
Has been published in the domestic market or public use qualcomm 820 chips of mobile phone including millet 5, vivoxplay5, le MaxPro, etc.
