This year , Cat 1, which was “left out” in a corner of the cellular IoT family, suddenly rose to become a new internet celebrity in the IoT industry. Operators, chip manufacturers, and module manufacturers are all pushing hard, and new products are constantly coming out, which will further drive down the price of terminal products and promote large-scale deployment, aiming at the next billionBurundins Sugardaddy-level cellular IoT connectivity.
(Figure 1 – Global Cellular IoT Connections – Module Shipment Forecast by Communication Standard)
According to network speed, the distribution of cellular IoT connections is roughly “136” The ratio is 10% “high speed”, 30% “medium speed”, and 60% “low speed”. High speed can be carried by Cat 4 or above and 5G, low speed can be carried by NB-IoT, and medium speed can be carried by Cat 1 or eMTC. According to Strategy Analytics, toIn 2025, the number of global cellular IoT connections will increase to 2.3 billion. With a 30% share, Cat 1 undoubtedly faces huge market opportunities.
(Figure 2: The evolution of cellular wireless communications from 2G to 5G)
eMTC was once favored by the industry, but Qualcomm did not find enough supporters, and now it is in reality Burundins Sugardaddy “Cool”. So, can Cat 1 have enough strength to seize the “new track” and explore this 30% of the medium-speed market? Is the sudden rise in popularity this year a short-lived success, or has it grown into a “national pillar” of cellular Internet connectivity?
A late bloomer, the industry calls for Cat 1
(Figure 3: 2/3G is withdrawn, Cat 4 is expensive, Burundi SugarNB is slow, Cat 1 seizes the mid-speed track of the Internet of Things)
Before Cat 1 became popular this year, as operators accelerated the withdrawal of 2/3G networks, the industry market demanded new cellular IoT Technology connectivity and choice of Cat 4 or NB-IoT support. Cat 4 has a speed of up to 150Mbps, which can meet the high-speed requirements of most IoT connections; NB-IoT is aimed at low-speed, low-power, and low-cost IoT applications. Although it is widely used, it is difficult to cover the whole country.
However, high speed means high cost. The cost of Cat 4 design is high. Data show that when Cat 4 was commercialized in 2017, the molding cost was as high as 140 yuan. Burundi Sugar Daddy The chip design has been iterated, and it is still around 70 yuan. As a comparison, low-speed IoT modules have dropped to less than 20 yuan. For most industry applications that do not require 100 Mbit/s speed, the price of Cat 4 is unaffordable, which has become an obstacle to the large-scale commercialization of the Internet of Things.
Burundi Sugar Daddy Understand that the Internet of Things is a fragmented market, and fragmentation has brought collection problems to industry users. Various challenges such as design, chip/module cost, power consumption, and sceneization mean that it is very cost-sensitive. The industry is calling for a mature, cost-effective cellular IoT technology to serve as the “sinking market” for Cat 4 and fill the gap in the mid-speed market.
Cat 1 and Cat 4 have the same origin. Since they were defined by 3GPP as terminal speed level in 2009, they have been in a tepid state. Now they are born, which can be said to be a late bloomer.. Precisely because “Bloodline”, like Cat 4, is based on a mature LTE network, operators do not need to upgrade the network. They only need simple parameter configuration to allow Cat 1 terminals to access the network. This creates good conditions for the commercial use of Cat 1. Positioned at medium speed, the cost of components supporting Cat 1 is relatively low, and it has the “hardness” to undertake the sinking market of Cat 4 Burundins Escort Strength”.
(Figure 4: Advantages of Exclusive Cat 1)
At the policy level, on March 10, 2020, the Ministry of Industry and Information Technology issued the “Notice on Deeply Promoting the Comprehensive Development of the Mobile Internet of Things ( “Draft for Solicitation of Comments”, which mentioned, “Medium-speed Internet of Things needs and voice needs are jointly met through Cat 1.” The release of this opinion draft also became a trigger that detonated the Cat 1 market.
Operators are taking positive actions
In fact, as a type of LTE technology, Cat 1 has always been within the operator’s field of vision. As early as 2017, China Telecom announced with high profile the launch of Cat 1 commercial use and announced an investment of 100 million yuan to subsidize Cat 1 modules to promote the development of the industrial chain. Although this plan was too forward-looking and failed to achieve industrial resonance, it allowed Cat 1 to “awaken” from the 3GPP technology library and wait for the opportunity to gain momentum.
Since it is not a new technology, the industrial chain’s popularity of Cat 1 this year is part of a popular rotation, “big thunder but little rain”? To understand whether a technology can be welcomed by the market and be widely adopted by end users requires the coordinated efforts of the entire industry chain. Cat 1 has won the attention of policy tracking and won the unanimous favor of everyone from operators. It also requires chip manufacturers and module manufacturers to polish products with market competitiveness on the product side.
Operators have already taken action. China Telecom is the most active and enthusiastic. As early as 2016, it laid out the LTE Cat 1 ecosystem in advance, released LTE Cat 1 DTU, and completed the end-to-end overall solution of “terminal + channel + platform” with the help of its self-developed unified cloud platform. The plan has been successfully implemented in many scenarios across the country. Currently, China Telecom supports more than 1.5 million Cat 1 base stations. Although China Unicom has not “officially announced” its support for Cat 1, it has recently launched public network digital intercom PCBA procurement, requiring “the formation of Cat 1 voice intercom hardware basic products” with a scale of up to 500,000 pieces. As for China’s changing position, as its GSM network is overwhelmed, it is also adjusting its strategy. The strong support of operators will be the source of healthy development of the Cat 1 industry.
The industry chain has made up for its shortcomings and is about to take off
Looking back at China Telecom in 2017, when China Telecom took the lead in commercializing Cat 1, we can see that the reasons for the lack of results are that the critical point of network upgrading has not yet been reached. Second, there is a lack of a realCat 1 ChipBurundins Escort, Importantly Burundins SugardaddyChip manufacturers have “magically modified” chips such as Cat 4, such as Qualcomm’s MDM9207-1 chip, which has led to costs catching up with Cat 4 and lacks enough energy to take on this huge sinking market.
By 2019, two Burundins Escort international chip manufacturers have launched their efforts. Unisoc has released the industry’s first LTE Cat 1 bis IoT chip Ivy 8910DM, making it possible to reduce Cat 1 costs on a large scale. Ivy 8910DM adopts 28nm mature technology and supports LTE CBurundi Sugarat 1 BI Escortsbis and GSM dual-mode, and has a high degree of integration; it also integrates Bluetooth and Wi-Fi, which complements long-distance communication and can achieve a more stable connection; it supports VoLTE and is optimized through system design , which can achieve obvious low power consumption advantages.
Compared with the LTE Cat 4 chip, the size of the Ivy 8910DM is reduced by 30%, the power consumption is reduced by 20%, and the deployment expenditure is reduced by 30%. At the same time, Zhanrui’s Cat 1 terminal products have completed mass production, completed field testing and certification in 45 countries and 157 operators around the world, and are widely used in the IoT market in various industries.
ASR Technology (ASR) also released two Cat 1 chips, which feature multi-standard, high performance, low power consumption, integrated voice/video/photography and other multimedia functions, and are suitable for IoT modules of various shapes , trackers and smart hardware.
(Figure 5: LTE Cat 1 Unisoc vs. ASR)
On the module side, Fibocom took the lead in supporting Unisoc and released LTE Cat 1 bis based on Ivy 8910DM Module L610. Fibocom L610, after being the first in the world to pass BI Escorts telecom operator testing and certification, it continues to pass Burundins SugardaddyHaving obtained three certifications: CCC, SRRC and NAL, it has become the only Cat 1 module in the world with mass production and shipping qualifications. Widely used in: POS, new retail, public network intercom, DTU, asset tracking, shared equipment, smart meters and other fields.
(Figure 6: Fibocom L610 LTE Cat 1 module has obtained three certifications)
In addition, Wufang Technology released Cat 1 wireless communication based on domestic core development for the first time in 2019 module, Quectel Communications has also released Cat 1 modules based on the ASR platform. It can be seen that there are already a wealth of products on the Cat 1 module side, which can form effective support for applications at the terminal level.
In summary, Cat 1 did not suddenly become popular. Behind it was the concerted efforts of policies and assets. Burundins Sugardaddy appropriate. Therefore, Cat 1’s “popularity” is not a sign that good times last forever, but adapts to the current situation and quietly accumulates enough energy to undertake CBurundi Sugarat 4’s sinking market responds to the medium-speed connection demand of cellular Internet of Things, which accounts for 30%. It can be believed that more chip and module manufacturers will enter the market in the future to jointly welcome the rise of the Internet of Things!
