December 31, 2013, Shenzhen-on World Telecommunication Day (December 31, May 17, the "2013 Shenzhen terminal Radio Frequency Technology Seminar" sponsored by microwave radio frequency network, an industry portal website focusing on microwave, RF, and wireless technology, was successfully held at the default Hotel in Bolin, Shenzhen. This seminar will focus on the hardware design and testing technical diffic

lasts about 9 hours, support for fast charging Network format WiFi (2.4GHz, 5GHz dual frequency), mobile 4G Let network Operating system Windows 10 Simplified Home Edition Extended interface Usb-c and HDMI Fuselage size 292x202x12.9mm (1.07kg) 309.6x210.9x14.8mm (1.28kg) Reference price 4699 yuan 6999 Yuan M

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus

multi-frequency multimode mainly related to the chipset of the handset's modem, the Gobi modem used by the Gaotong's processor can be said to support the true 4G LTE global model, support LTE FDD, LTE TDD, WCDMA, cdma1x, ev-do, TD-SCDMA and GSM. Gobi 4G LTE Advanced with carrier aggregation speeds up to Mbps. The current use of Xiao 800 processor Nubia Z5s Kte

-speed hspa+ network. For example, Huawei P7 Mobile version adopted the Sglte scheme, but the Unicom version is CSFB.Different versions of the same model phone, RF-related chips may differ. For example, this figure is the iphone 5S two version of the RF chip area of the comparison chartSglte: Communication Network two not delaySglte (also known as "dual standby") The biggest feature of the mobile phone is the simultaneous built-in support for both LTE and GSM RF chips, can simultaneously achieve

music enthusiasts, this machine has a professional sound technology, by the Grammy Award-winning team in person to adjust, optimize the high, medium and low three-frequency quality, but also enough to experience professional standards. At present, the double 4G version of Lenovo K3 note Price 899 yuan, the spot hot sale, to its interested friends can go to buy. 　　The charm of the Demon Blue Note (1168 yua

platform can provide better performance and lower costs than the traditional platform in the past. The network performance is easier to optimize and the network structure is more flexible ." In terms of network performance improvement, China Telecom is focusing on three major issues. The first is the main 4G frequency band based on China Telecom's 1800MHz and 2100MHz, which makes the

For an RFID system, the concept of Frequency Band refers Frequency Range of tag signals sent, received, and read by the reader through an antenna . In terms of application concept, the operating frequency of the RF tag, that is, the operating frequency of the RFID system, directly determines all aspects of the system a

Recently, the millet combined with China Mobile published "Millet Notebook air 4G", its bright spot is to support mobile 4G, but also the use of virtual card design, air activation, open the box is used. So, what about the Millet notebook air 4G? Next, small series for everyone to bring millet notebook air 4G detailed

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)

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

　　Gionee M5 (2299 RMB) click to buy For Gionee M5, people are more concerned about its strong performance, the machine built 6020mAh capacity battery, one charge can be used for 4 days without recharging, and such products are also created a smart phone "power" record, and the machine has absolute strength in terms of endurance. In addition, the machine is also a support for all netcom 4G mobile phones, dual SIM card is also its basic attributes, it

when the criticism. If you exceed the frequency, 200 FSB to 240, then the equivalent frequency of memory is equal to 240/200.x1333=1599mhz, more simple than K8, but simplicity, the overclocking is still to pay attention to the frequency of memory to keep pace with FSB, if the wing Dragon 2x4 955 of 200 FSB to 250 FSB, plug in DDR3 1333, set to auto in the BIOS,
