Although Apple has not yet issued an invitation letter, it seems that it has been leaked by the "teammates" in advance of this year's Apple Autumn Conference. Recently, a video website in China has started the live broadcast reservation for Apple's 2016 new product launch conference, which not only confirms that Apple will hold a new product launch conference on September 7th (Beijing time on September 8th), but will also launch The release includes a variety of new products, including the iPhone7, the new MacBook Pro, the second-generation Apple Watch, and the 12.9-inch iPad Pro, making it the most colorful new season in history.
Shipment order exposure
It is worth mentioning that some netizens have exposed an export freight bill that is said to be the iPhone 7 on Weibo. The information displayed is “Apple new product, designated flight, single shipment, can not be shipped togetherâ€, so if If the news is true, then it means that this year's iPhone 7 has started shipping to the United States, and then we will meet with us soon after the release. Previously, the big news @ evleaks once again confirmed that the iPhone 7 and iPhone 7 Plus will be released on September 16th, so the leaked shipper can be confirmed as such.
However, although the iPhone 7 has begun shipping to the United States to sell, the industry has reported that the iPhone 7 may face serious shortages, because the capacity of some components can not meet the demand. Although many people speculate that it is possible to have a dual camera module or a TSMC 16nm A10 processor, according to the market DRAMeXchange news, SK Hynix, one of the major suppliers of iPhone 7 memory particles, has not passed Apple certification. Will shift orders to Samsung and Micron, so it will affect the production capacity of the iPhone 7.
With A10 chip
In addition, there are also netizens who also disclosed the main specifications and features of the iPhone 7 and iPhone 7 Plus. The former is said to be a 1080p touch screen, while the latter is a 2K resolution display at full load. The TSMC A10 processor with 16nm process technology has a 30% performance increase and a 20% reduction in power consumption. It also uses Samsung and Hynix's 20nm process memory chips. Among them, the iPhone 7 is 2GB of memory, while the iPhone 7 Plus has 3GB of memory and has three contacts on the back to support touch-based wireless charging.
Unlike the past, the iPhone 7 has two new cameras that are dual cameras. The netizen said that the iPhone 7 is equipped with a single lens, while the iPhone 7 Plus is a dual camera. Both will have a larger capacity battery and improve battery life. 20%. The sound quality of the phone will also be improved, and the true tone sensing technology will be added, while the home button is still the same, but it cannot be pressed. In addition, this year Apple will launch three new models, including iPhone 6SE, iPhone 7 and iPhone Plus, but the iPhone 6SE will use the iPhone 7 camera, and the rest of the components are the same as the iPhone 6s.
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.
