With the NB-IoT this year, shipments reached 50 million, 100 million next year point of view, after doing my part to the rapid rise of a high-speed networking between (5G and 4G LTE) and low-rate (2G GPRS and NB-IoT in rates between) (including 3G, Cat.1, eMTC (catm)) market is on the rise. 4G LTE Cat 1 bear the timing of things the main connection has opened. Which, Category 1 level configuration of the user terminal as a minimum version of the argument, so that the industry can cost-effectively design "low version" of 4G terminal, generally referred to as Cat 1. Therefore, the development of Cat 1 network and related industries, the main scenario for the padded things demand makes sense.
Different conventional mobile communication technology, 4G LTE not identical homogenization of service to all users, LTE network operator the user classification stratified in various ways, with different network capabilities and services. Such as (QoS) protocol, operators will provide users with quality services in accordance with the user entered into a special customized services, including bandwidth, priority access and other support. The industry more familiar hierarchical grading service is the ability to provide different service levels according to terminal access capability, namely UE Category (end user level).
The relevant 3GPP standards, UE category is a set of the uplink / downlink wireless performance variable parameters, comprising a number of radio characteristics, the most important is a rate supported by a user equipment. The correspondence relationship of various "UE Category" and supported rates indicated in the table below:
In the market distribution in a cellular connection, high-speed connection to occupy 10% of the share, the connection rate of 30%, accounting for 60% of a low rate. With 2G disconnection, NB-IoT technology can fill the gaps and meet the low-rate, low-cost needs. With 3G disconnection, Cat. 1 and eMTC capable of carrying voice-oriented mainly, the low rate and the market.
However, compared to Cat.1, eMTC opportunities in the country is not large. eMTC development in China is not optimistic, eMTC need infrastructure, and operators will now devote more resources to 5G construction, it is difficult to have extra money into eMTC construction, in addition to limited domestic application case, can reference is not high, a large development effort. Therefore, Cat.1 will undertake the huge cellular market rate accounted for 30%.
At present, China Mobile, the country has 2.8 million 4G base stations, covering 98% of the area, including the vast rural areas, serving more than 700 million users. China Mobile proposed the joint development of 5G + 4G, 4G network as the main service bearer network will be ongoing optimization, quality build 4G network. Cat.1 product has completed 30 provinces, municipalities and network testing completed 65 overseas countries and regions, it is already a mature network.
Cat.1 have a certain cost advantages, for example, a network construction is now LTE Cat.1 seamlessly into the existing LTE network which, without the need for hardware and software upgrades for the base station, the network coverage low cost. Chip cost, after the system optimization, higher integration module hardware architecture simpler, lower cost of peripheral hardware. In terms of delay, we have the same with the LTE Cat.4 millisecond transmission delay, and to support the moving speed of more than 100KM / H's.
In some applications, by Cat.4 migrate to Cat.1. Such as walkie-talkies, toy robots such as the use 4G to do voice interaction scenes, before using Cat.4 can switch Cat.1. Many scenes in voice and rate of the connection, will have to play at the Cat.1 of. These scenarios include the sharing of financial payment, industrial control, car payments, public speaking, pos, etc.
Faced with such good technical market environment, the miracle of things together, how can absent. In 2020, the company will launch CAT1 product -AM430E, AM430E is a support multi-standard, multi-band LTE-TDD / FDD / GSM / GPRS / EDGE of LTE CAT1 application modules. Supports VoLTE voice, support download speeds of up to 10Mbps and 5Mbps upload speed. Has strong scalability, built-rich network protocols, integrating multiple industry-standard interface, and supports a variety of drivers and software capabilities, providing customers with great flexibility of use and ease of integration, it can be used as cloud horn, POS, POC, FWP and so on.
