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 difficulties and hot spots of next-generation LTE (

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 bands, so there will be different vers

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) or Fdd-

Since operators are facing a near-crazy demand for mobile data, there are at least four different areas where data congestion can occur, including: • Wireless access network; • Network signaling and Control section; • cluster core network; • Return network. Each bottleneck is a special challenge for operators, which can be solved in one of the following three ways: 1. Increase the capacity of the affected network resources; 2. Streaming network resources to alleviate congestion; 3. Both

In the reality development, the common executionstats pattern, this example analyzes this mode.> db.createcollection ("Person"){"OK": 1}> for (var i=0;i... db.person.insert ({"Name": "Ryan" +i, "age": i})... }Writeresult ({"ninserted": 1})> Db.person.find ({"Age": {"$lte": +}}).

the use of the voltage ratio of both calculation, to use 20log (methyl voltage /b voltage). [Example] a power than the second power of one-fold, then 10LG (a power/b power) =10lg2=3db, that is, a power than B power of 3 DB. Conversely, if the power of a is half of the power of B, then the power of a is smaller than the power of B 3 DB. Summary: DBM is a negative number, the closer to 0 the higher the signal strength, the better the signal, but not 0. ASU is positive, the greater the value the

as a microSD expansion card, and if you are a Tanka user, you can combine a single SIM card +MICROSD expansion card scheme, as shown in the figure. Glory Note8 Card Loading steps: First, the Glory Note8 mobile phone shutdown; Second, the use of the box with the needle, the glory of the Note8 fuselage left the upper part of the SIM card out; Third, install the Nano SIM card into the slot 1 or 2 position, and reload the card into the phone. Four, acti

With the development of China's routing industry, many emerging technologies have emerged. IP routing technology is widely used in routing technology, here we will mainly analyze the practical principles that should be followed when using IP routing technology, from the perspective of the transmission network, I think it is necessary to carefully check whether it has the Bandwidth Reservation for processing QoS and users' mobile terminals in the whole IP environment. Speech traffic and other hig

upload and download. The advantage is that FDD saves a lot of time and consumes more resources (in fact, TDD needs to reserve a large protection band to avoid interference and consume some resources ). Because it is a "one-way street" that runs two-way "traffic flow", TDD can only control traffic through time (Time Division Duplex), so that the downloaded traffic will pass through and the uploaded traffic will pass. Many people put TD-SCDMA and TDD together, in fact, there is no relationship be

How is the development of 4G + operator? In the recent period, 4G + has become a keyword that the three major domestic operators are scrambling to mention. The so-called 4G +, is the LTE-A (LTE-Advancde), is based on the original 4G network, the use of carrier aggregation technology (CA), further expand the network spectrum, network quality optimization, in essence, 4G + is the evolution of 4G technology.

Recently in the project to use mobile terminal equipment, naturally inevitably need to remove the mobile network problems.Saying that many leaders actually do not know the technology, always like blind pursuit of new, like to discuss 4G.In fact, through my many aspects of understanding, (well ~ My daughter-in-law also want to start a kidney six, so carefully analyzed a bit)In fact, 4G is still in a very impractical stage, so we still choose to Unicom 3G best.In fact, now so-called Fdd-

Cao Shumin, member of the CPPCC National Committee and vice president of the Institute of Telecommunications, said yesterday that, as the only major national science and technology project in the communication industry, "Next-generation broadband wireless mobile communication network" will obtain at least 2 billion yuan of national financial investment this year and next, and the initial funding for enterprises and local support is estimated to be about 10 billion yuan.This project sup

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-lte
