GSM system is the world's most widely-covered second-generation wireless network, it uses TDMA (time division multiple Access) approach, that is, in a carrier channel, at the same interval at the same intervals into a fixed cycle of several time slots, each time slot carries a business user information and necessary signaling. In this way, a carrier channel is occupied by a number of users in chronological order, with different time slots as a way of distinguishing different users. Characterist

Process from MAC layer to physical Compared with the general r99 channel, HSPA channel introduces harq and other technologies, so several different processing steps are added. Fast Link adapation This is a very important HSPA technology, because the speed and priority of data transmission in the empty mouth are related to power, which is very different from that in wired networks. The WCDMA System is an uplink interference system. Therefore, po

The Charm Clan MX5 cracked unicom/Mobile 4g/3g (TD-LTE/TD-SCDMA/FDD-LTE/WCDMA) Prerequisite: To ensure adequate electricity, at least 50%. Use pea pods, application treasure, etc. to back up important information. 1, download MX5 General edition firmware (http://www.flyme.cn/firmware.html) 2, after downloading, the handset and the computer through the data line connection. Hint: The screenshot below is for MX3 screen capture, where there m

The application of wireless access networks is still very extensive. Many people may not know about wcdma in Wireless Access networks. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you more things. In the past 10 years, mobile communication technology has developed by leaps and bounds, and has gone through the first generation of analog mobile communication, the second generation of digital

WCDMA is the English abbreviation of wideband Code Division multiple Access (wideband Code Division multiplex), which is a third generation wireless communication technology. W-cdmawideband CDMA is a third generation mobile communication system, which is developed by 3GPP, based on the GSM map core network and Utran (UMTS terrestrial Wireless access network) as the wireless interface. Currently, WCDMA has r

With the convening of the Olympic Games, the third generation mobile communication system is getting closer and closer to our lives, the trial commercial use of China Mobile TD-SCDMA, this gives our Chinese people the opportunity to enjoy the various high-speed data transmission services 3G brings to us in China. I believe that in the near future, there will be two other technologies (WCDMA and CDMA) we will also enter our lives to enrich Chinese peop

After years of development, the mobile communications industry has entered a period of rational development, but also face more and more fierce competition, the future of competitive 3G network should have a higher cost-effective, provide a sound service and first-class network quality, of course, must also be a good network design to fully protect investment. The third generation WCDMA system has introduced the Code Division multiple Access (CDMA), i

Recently, there is a project abroad to use the WCDMA cat, online simple selection of the model of the decision to use ZTE Mf667s Cat, this thought in the Linux number is relatively simple (before there are two 3G cat debugging experience), estimated half a day can be done, the results toss a week to adjust, Record the pits encountered during the commissioning process.1, Mode switchBecause the cat now has a variety of models, the purpose is to Windows

3G Early-stage network planning determines the network structure to a large extent, plays a decisive role in network investment and quality, and is the foundation of future network development. 3G Development, network quality is the most important, no good network quality to do support, no good business can not be achieved or better. The metrics for measuring network quality can be said to be numerous. For 3G, network planning, including wireless and core network planning, can be said to be an i

Welcome to the IT technology community forum, and interact with 2 million technical staff. Table 1 Comparison of WCDMA and GSM signal distribution from the relationship between RSCP and EcIo, when RSCP approaches-100dBm, the corresponding EcIo is-7 ~ -9 dB, and EcIo will reach below-14dB when RSCP is below-110dBm; when the pilot signal is clean, RSCP is-105dB Welcome to the IT Community Forum and interact with 2 million technical staff> Table 1 Compar
