2019 smart home solution trend forecast

图片
In the past 2018, smart speaker battles have come one after another, and connectivity solutions and whole-house system solutions have emerged in an endless stream. In 2019, what are the trends in system solutions, technologies, and chips that vendors are concerned about? Richerlink has put together some ideas, and in 2019, smart homes are still hot. NB－IoT As the core of the Internet of Things strategy of the three major operators in China, NB-IoT has gradually formed the world's largest industrial chain in China. To some extent, low-power wide-area networks have made IoT terminals and sensors a direct user service contact, bringing directly needed resources to operations, and have become an important factor in the development of the Internet of Things. According to Machina Research's May 2015 report, the total number of terminals that have achieved network interconnection in the world in 2015 is 16 billion. By 2025, the number of M2M (Machine to Machine) connected devices...

Introduction to the hierarchical model of GPON

GPON technical features are mainly reflected in the transmission convergence layer. The transmission aggregation layer is further divided into a PON frame sublayer and an adaptation sublayer. The framing sublayer of GTC (GPON Transmission Convergence) completes the ODN transmission function required for the encapsulation and termination of GTC frames. The specific functions of the PON (such as ranging, bandwidth allocation, etc.) are also terminated at the framing sublayer of the PON. The gametophyte layer is invisible. The adaptation sublayer of the GTC provides an interface between the PDU and the higher layer entity. The ATM and GEM information completes the conversion of the Service Data Unit (SDU) and the Protocol Data Unit PDU at the respective adaptation sublayers. The OMCI adaptation sublayer is higher than the ATM and GEM adaptation sublayers, which identify VPI/VCI and Port-ID and complete the exchange of OMCI channel data with higher-level entities. Application of GPON in ...

What are the differences between EPON and GPON?

1. EPON and GPON technology EPON (Ethernet Passive Optical Network) is an Ethernet-based PON technology. It uses point-to-multipoint architecture, passive fiber transmission, and provides multiple services over Ethernet. GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network services. 2. EPON and GPON rate EPON provides fixed uplink and downlink 1.25 Gbps, 8b/10b line coding, and an actual rate of 1Gbps. GPON supports multiple speed grades, can support uplink and downlink asymmetric speed, downlink 2.5Gbps or 1.25Gbps, uplink 1.25Gbps or 622 Mbps.According to actual needs, the uplink and downlink rates are determined, and the corresponding optical modules are select...
