At present, many new wireless routers have dual-frequency to do the selling point, the popular Route 2, millet routers are supported dual-frequency, where the dual-frequency refers to the 2.4GHz and 5GHz, then 2.4GHz and 5GHz routers What is the difference? What are the advantages and disadvantages of 2.4GHz and 5GHz routers? 2.4GHz and 5GHz are two bands without affecting transmission speed. Many netizens may ask the wireless router i
The usage of the ultra-high frequency band in various countries is 7. Unfortunately, the weekly frequency bands used in Japan, the United States, and Europe are different. As mentioned above, UHF is the longest communication distance and can be used for unified reading of items in the supply chain. In international logistics, it is impossible to add RFID tags to each country that passes through circulation, the RFID tags developed in a region must

few clock cycles to implement a single bit operation, and increases the amount of code Two. The significance of the band area How can be like MCS51 in the middle bit operation, sbit P1.0 = p1^0; P1.1 = 1; the bit segment and the bit band alias area of the STM implement this function. Can operate SRM, peripheral I/O for bit operation, The STM32 supports bit-band operations (Bit_band) and has two zones that implement the bit bands. One is the lowest 1
This is a warm photo taken indoors, and has been liked by fashion girls in recent years. In the shooting, we used the indoor natural lighting, the overall dark film, the face area light is also less ideal. Later we mainly use the "color level" command for the overall tone adjustment, using Lasso tool to select the face area, and then use the Curve tool to increase the brightness, and finally use the plug-in grinding process to achieve the warm fashion we want the effect of the photo.
insert time and seconds in the database. Generally do this kind of operation with the framework mostly, I say hibernate it. In a database table, the field type is set to the date data type, and the field type mapped in the code is set to Timestamp type, private Timestamp date; In the mapping file There's one more thing to say. The yyyy of the format time when using SimpleDateFormat. MM.DD is the date of the year. If you want the format time to be 12-hour, use hh:mm:ss if you want the format ti
Millet notebook air 4G and before the normal version, divided into 12.5-inch small screen core and 13.3-inch display version, a total of 2 versions. The following is the 4G version of Millet air detailed parameters: Millet Notebook Air 4G version configuration Version contrast Millet Notebook Air
disassembly that it used a high-pass mdm9615m baseband chip, a "secret weapon" that was hidden from the iphone 5 era, which supports LTE (FDD and TDD), hspa+, ev-do version B and TD-SCDMA, GSM, and other formats , the legendary 5-mode 11-frequency chip, so in principle, the world's iphone 5s can support China Mobile 4G (TDD), the difference is that Apple in different regions "artificially" to lock some frequency
Compared with 2g/3g, 4G is the biggest feature is to provide a peak rate of more than 100Mbps, since the speed can be off 20M of fiber-optic fixed network, that used for voice calls is a piece of cake? Unfortunately, this is where the problem arises.Because the current LTE network (4G) does not support voice services, so whether it is Td-lte (mobile 4G) or Fdd-lt
Compared with the 2g/3g, 4G the biggest feature is to provide more than 100Mbps peak rate, since the speed can be seconds off 20M of optical fiber fixed network, it is used for voice calls is a piece of cake? It is a pity that the problem arises here. Since the current LTE network (4G) does not support voice services, so whether it is Td-lte (mobile 4G)
2G/3G/4G? In addition, GSM is mobile and Unicom 2G,TD-SCDMA is mobile 3G,WCDMA is a mobile 4g,fdd-lte is the 3g,tdd-lte is another kind of the world's 4G, the future may also be unicom and China Telecom will use 4G network. Note that Fdd-lte is a possible network technology for China Unicom and Chinese telecom, so if
How can the three major carriers innovate their networks when they face the "4G 4G" challenge? 4G development in 2015 is about to enter the fourth quarter. At the latest "LTE Network Innovation Seminar" sponsored by the TD Industry Alliance, a group of the latest statistics published by the Secretary-General of the TD Alliance shows that, with the three major ca
Great God F1 Speed edition (699 yuan) Great God F1 speed version of the current off-the-shelf, whether in the cool-pie mall or Jingdong can be the first time to buy, and the machine 699 yuan Price absolutely let people echocardiography. If you think it's a low machine or a geriatric machine, that's a big mistake. The machine built-in 2GB RAM running memory, whether it is playing a game or multitasking can have a good performance, and this machine is currently has 2GB RAM to run the lowest pri
GF's iphone5s port version A1530 Unicom 4G is always unable to connect the problem, the root cause is that there is no 4G switch . The Hong Kong iphone only has a 3G switch. That is, when the 3G is turned on, the 4G signal is found, but only 3G and 2G are turned off. Let the phone signal stay on the 4G signal network.
