The future era is the 4G era, new phone users of the search volume is not under the computer. So, how do we use mobile phones for marketing? Mobile Site bidding articles, how to write better? Mobile website to do the topic? Where is the optimization idea of mobile website? The system of the handset is different, on the different handset, the user experience degree is not the same. How do we achieve perfection? For these questions, the new Chen for you

4G TDD-LTE and FDD-LTE two models, do you understand? At present, there are two 4G standards based on LTE, namely lte fdd and lte tdd (China is used to call lte tdd TD-LTE, both standards are based on different branches of LTE, with a similarity of more than 90%. Next we will use traffic as an example to analyze the differences between the two: I. TD-LTE saves resources and FDD is fast Lte fdd (Frequency

With the development of global 4G networks in full swing in recent years, how to simplify the deployment of remote adjustment antennas and improve their reliability has become a new concern of operators for the antenna feed system. Due to its inherent requirements for on-site access, low operation and maintenance efficiency, and affected antenna radiation performance, the method of mechanical tilting optimization antennas has gradually withdrawn from

The recent 4G mobile phone under the Spit slot: 1.iphone6 and 6p, respectively 4.7 and 5.5 "screen, 1810 and 2915 mah non-removable battery, dual core 64-bit Apple A8 processor. Battery capacity is too small, not durable, medium use a day, and does not support VOOC flash charging technology. To buy a slim mobile phone and a two or three times-fold thick mobile charger is how brain-crippled. The most despised person is, with more than 6,000 mobile phon

Brief introductionQMI--qualcom message Interface literal translation is a high-pass messaging interface. As the name implies, the purpose of this interface is to define a direct communication message with a high-pass device (mainly modem).QMI English complete information is as follows:Since the recent development of a MiFi device based on the QMI 3\4g dialing, so recently I will be in this process encountered problems, and some experience in a success

Because in the card 1 so we only need to enter the mobile phone network management to switch, the specific steps shown in the following figure. 1. Under the Standby page, click "Application". 2. Click "Set". 3. Slide up the screen and click on "More Networks". 4. Click on "Mobile network". 5. Click on "network Mode SIM1". 6. Click on "3g/2g (Automatic connection)". 7. After reading the network switch prompts, click "OK". Okay, so our cell phone has successfully shut down

1. Open the 4G network is very simple in fact, we just in the mobile phone "application" can be deleted.2. Then we click "Set" in the Open interface.3. The following "more networks" are entered, as shown in the following figure.4. Click on "Mobile network".5. In the above figure we click into the "network mode" entry, details below.6. Furthermore, we click on "3g/2g (automatic connection)" to enter, as shown in the following figure.7. Click "OK".

because of some requirements, to temporarily build a local network, to a small range of mobile clients to provide specific network services, such services typically contain common HTTP services, data file download service, restful interface services, etc. Common non-enterprise-class wifi mifi user connections are less, more than 10 connections can not be used normally, and according to the actual conditions, often need to use the 3g/4g Span

Why the 32-bit system can only operate 4g memoryA lot of cells in computer memory, each cell is a byte, a byte has 8 bits. There are two states of each unit: 0 and 1.So There are 4 combinations of two units; There are 8 combinations of 3 units; In turn ... ； n addresses have a 2 n-th-square combination. 32-bit computer, there are 32 units, you can control 2^32 units, that is, 2^32 bytes, that is, 2^32b, equals 4GB, so the 32-bit syste

to technical system lags behind, weak data bandwidth capabilities, and poor mobility, it is difficult to meet the development requirements of industry private networks. To help private network users solve the above problems, narrowband Digital cluster technology has clearly evolved to a broadband multimedia Cluster Based on LTE, the TD-LTE-based broadband multimedia digital cluster solution is favored by users in the private network market. Cluster technology enters the

meets the data needs at a certain time point. What is the situation of Wi-Fi? It may face various threats. On the one hand, it comes from the rapid development of mobile WAN technology; on the other hand, the construction of micro-cell Femtocell) base stations, micro-cell Picocell) base stations and other base stations to catch up quickly. In addition, it cannot be ignored that some enterprises may need to install a mobile WAN System in the building to comply with Wireless Public Security Regul

Which of the following is the best 4G technology? Clarify the relationship between FDD and TDD (1) 1. Technical aspects: they are all born with a mother-in-law. The technical differences between FDD and TDD are actually very small. The main difference lies in the adoption of different duplex modes. FDD and TDD are two different duplex modes. FDD is used to receive and send messages on two separated symmetric frequency channels. It uses protective fr

Our current RTSP video solutions are as follows:Webcam If the NVR uploads via wired, there is no pressure to upload the main stream data, but if the 4G card is used to upload, the use of sub-stream will show the phenomenon of flower screen and skip frame. If the third stream is used, there will be no skip frame phenomenon. When the gimbal rotates, the flower screen phenomenon is not serious.The sub-stream settings are as follows:The third stream is se

According to the data provided by Apple's Hong Kong official website, the Hong Kong iPhone 6 has two models: A1549 and A1586. Among them, A1549 is divided into GSM and CDMA version, GSM version supports GSM/EDGE/WCDMA/FDD-LTE standard, the CDMA version supports GSM/EDGE/CDMA EV-DO/WCMDA/lte fdd standard. While A1586 and the domestic version of the network standard, support GSM/EDGE/TD-SCDMA/WCDMA/CDMA EV-DO/FDD-LTE/TD-LTE network, without compromise 3G/4
