In the afternoon of November 22, Xiaomi TV held a new product launch conference in Beijing this afternoon, and released Xiaomi Internet Speaker, which sold for 399 yuan and was on sale on Friday.
The appearance of this device is pure white design, the top 7 button is made of metal brushed panel, the style is similar to the layout of the millet TV split host.
Content partners access to cool music, shrimp music, millet music, Kukka music and Beva in music content. The radio station has access to Himalayan, radio, koala FM, Phoenix FM, and Litchi FM, including most of the country's radio stations, as well as audio books and children's programs.
Xiaomi Internet Speaker Configuration
Speakers can be connected via the Xiaomi Speaker App, which currently supports Android and iOS devices. Different channels can be customized for different users on the App side, and can be switched by the CH channel key. It also supports multiple phone connections and multiple user connections.
At the same time, Xiaomi Internet Speaker also supports voice operation, which can be used for voice-on-demand music and audio services.
In addition, speakers can be connected to other devices via Bluetooth, WiFi (AirPlay, DLNA) and AUX in 3.5mm interface.
There is a USB 2.0 interface on the body, and there is 8GB of storage space in the speaker for storing audio content in offline mode.
The sound quality supports 192Hz/24bit, and the configuration adopts Amlogic 8726M3 Cortex A9 processor and supports 802.11ac dual-band WiFI. Also supports Bluetooth 4.1, 3.5mm interface, 8GB storage space and USB 2.0 interface.
Analysis of advantages and disadvantages of 4G industrial routers
First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.
For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.
Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.
Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.
Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.
