1 Development of Optical Fiber Communication In 1966, the Chinese Scholar Gao was a Chinese scholar. k. KA) and hawkhaamu C. k. HOCKHAM) published a paper on the new concept of transmission media, pointed out the possibility and technical path of using optical fiber OpticalFiber for information transmission, and laid the foundation for modern optical communication-optical fiber communication. In 1970, the development of optical fiber has made significant breakthroughs, and substantial progress h

This typical arrangement is oftenis called SIP之梯(SIP trapezoid) .When Alice calls Bob, she uses the SIP identity information of Bob, a specific type of URI called the SIP URI, similar in form to an e-mail address, containing the user name and host name.In this example, Bob's

Interval Update here uses the maintenance of the Line Segment tree. We create a discrete array. Each node stores the sum of the upper and lower bounds, indicating whether a rectangle exists. If so, each node uses the sun array to save the difference value of the X value of this rectangle (through the subscript of this discrete interval, subtraction is the difference value of discrete X ). At last, multiply the difference value of Y. The area of the scanned matrix.

. There are two key concepts in this equation: Data and query. These two completely different concepts are often confused, so let's take a look at what these two concepts actually mean. Data "Data" has two key properties. First,Data is time-related.A real data must exist at a certain point in time. For example, if Sally writes in her social network profile that she lives in Chicago, the data you get must have been filled out in Chicago some time ago. If Sally updated her profile to

In consideration of commercial interests, the SWP architecture eventually won the consistent support of the operator (GSMA), but the original SWP standard is still immature and needs to be further improved. At this time, Phillips finally gave up another single-line standard that he proposed again, annou

occupy all the text message interaction more than 95%), then we should simply go to dig deeper into the 10 interaction between people, this should be the direction of innovation. Summarize Individuals classify these applications as a point-to-point interactive application based on the address book, and the point-to-point interaction differs from the current social tools, and is more intimate and targeted. As with most social activities in the real world, there are clear objects and motivation

LifeWhen the nodes in the LoRaWAN network are ready to send the data, the communication between them is asynchronous, whether it is an event-driven or a scheduler. This type of protocol can refer to the Aloha approach. In a mesh network or a synchronous network, such as a cellular network, nodes need to wake themselves up frequently to maintain synchronization with the network and to check messages. This synchronization consumes a lot of energy and is the first driver of a lower battery life. I

With the division of spectrum resources, a huge rock in the road of TD-LTE commercialization was moved. At the recently held "TD-LTE technology and spectrum Seminar", China's 2.6GHz spectrum planning scheme was announced,-2690hz of the 2.6GHz band all divided into TDD spectrum. The determination of spectrum division, which sent a clear signal to the TD-LTE industry chain, eliminating the concerns of manufacturers involved in TD-LTE, TD-LTE commercialization process has taken a very critical step

GSMA believes that by 2025 there will be 27 billion Iot connections, about 70% of which are short-distance connections. Specifically, the number of mobile connections to IOT in 2016 is 0.45 billion, which will reach 2025 by 5 billion. The number of cellular IOT (2G/3G/4G) connections will reach 2025 by 2 billion, and the number of LPWA connections will reach 2025 by 3 billion. By 2022, 56% of the active LPWA connections will adopt the authorization s

When we made this product last year, SE designed a push function on the client, and SE researched and decided to integrate Baidu's cloud push SDK on both Android and iOS to support this push feature. The recent leadership in doing operational analysis, found that the cloud push reports show that the Android side of the message is very low, the device's online rate fluctuations are relatively large, sometimes high sometimes very low.Our product after nearly two years of frustrating progress is ob

What are the unique IDs for mobile devices (mobile phones)?In mobile advertising, the ID of a device is used to track the most important identity of a person.For the app's own products, using the device unique ID can track the user's entire process data from download to activation, registration, use, churn, and regression, which is very helpful for product operation.For precision advertising and personalized recommendations, you can use the device ID for data collection, and then the thousand-fa

VoLTE that voice over LTE, it is an IP data transmission technology, without 2G/3G network, all the services hosted on the 4G network, can realize the data and voice services under the same network of unification. In other words, 4G network not only provides high-speed data services, but also provides high-quality audio and video calls, the latter requires volte technology to achieve. VoLTE is a voice service based on IMS. Because of its support of multiple access and rich multimedia ser

example, turn on the air conditioner or open the door. This raises the question that your gateway is typically located behind the router, not directly from the Internet. Some solutions do not require port forwarding, but this also requires a dynamic DNS solution that requires user configuration. What the general company does is that the mobile app sends the instructions to the cloud, and then the gateway gets the instructions from the cloud.
