In recent years, the increasing demand for mobile data services has promoted the acceleration of LTE network commercialization. Throughout the world, LTE commercial networks are still dominated by lte fdd, but with the gradual development of their networks, users and businesses are increasing, lte fdd network frequency

China's LTE commercialization is approaching, and the industry's attention to the subsequent evolution of LTE has reached a new peak. Compared with 3G, LTE significantly improves the spectrum efficiency. However, the industry has not stopped. A few years ago, 3GPP began to research and develop the LTE-Advanced standard

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 stand

Currently there are two 4G standards based on LTE, namely LTE FDD and LTE TDD (the domestic custom of LTE TDD is called Td-lte). See the name you will have an intuitive impression, the two standards are based on the different branches of

LTE beginners, if you also for the LTE self-study and confused;LTE scholars, if you're still worried about the effectiveness of LTE learning,If you want to learn LTE well instead of simply learning about LTE,To make

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 b

, and there is only one pcfich in each carrier; Physical downlink control channel (PDCCH), including downlink Dispatch and uplink dispatching authorization information, each PDCCH carrying one or a set of terminal information; Physical Mixed Arq channel (PHICH), carrying Harq feedback information; Relays the physical downlink control channel (R-PDCCH), which is used when relaying. As mentioned above, the size of the control domain is up to 3 (4 in narrow bandwidth). However, wit

In December 5, Wei leping, director of China Telecom Technology Commission, said that after China Telecom obtained a 4G license, it will coordinate the coordinated development of LTE and FTTH and give full play to its respective advantages ~ In the past 10 years, LTE and FTTH will be two major technical levers for China Telecom. In terms of 4G network planning, China Telecom will first adopt TDD and FDD hyb

Influence of LTE technology on PTN China and the rest of the world are entering the brand new 4G/LTE era at full speed. As a mobile return technology, PTN faces severe challenges even after years of evolution and maturity. Some of these technological changes are huge enough to trigger a PTN revolution. This article takes into account the deployment of macro base stations and micro base stations, and review

Layered Structure of LTE air Interfaces Layered Structure of LTE air Interfaces LTE air interface layer structure, and WCDMA air interface layer structure is the same, from top to bottom is also divided into several layers of RRC-PDCP-RLC-MAC-PHY, RRC belongs to the network layer, PDCP, RLC and MAC belongs to the link layer, PHY belongs to the physical layer. T

Network Collaboration of TD-LTE Is there mutual interference between the TD-LTE and the current 2G system in the adjacent frequency? How can this problem be solved? A: In actual network deployment, the F-band (1880-1915 MHz) TD-LTE base station will be affected by the stray/blocking/Intermodulation Interference of DCS1800, the Second Harmonic Interference of GSM

Latest Advances in TD-LTE Testing At present, the first phase of core network, transmission, bearing and security testing work has been completed in the six test fields of TD-LTE. The results meet the test expectations, and all of them have entered the formal test conditions, in the future, the wireless performance, multi-antenna, terminal, indoor distribution system, network management and other aspects of

Multi-frequency and ultra-Broadband Antennas must not be underestimated in LTE deployment According to the latest GSA (Global mobile Suppliers Association) statistics, operators in 112 countries around the world have commercialized 331 LTE Networks. It is estimated that by the end of 2014, the number of Global LTE commercial networks will reach 350. With the ar

Modern mobile communication tends to provide high-speed transmission multimedia services. The birth of LTE family base stations effectively improves the coverage, throughput, and transmission experience of the system in hot areas. In the standardization process of LTE, the concept and technology of a family base station HomeeNodeB and HeNB came into being. Unlike traditional cell communication base stations

As an evolution after 3G-4G, do you know its technical characteristics? As one of the 4G standard record filing systems, wireless TD-LTE-Advanced adopts the multi-access method, frame structure similar to TD, and wireless MIMO technology. The following is a detailed introduction. Features of wireless TD-LTE-Advanced Technology 1. Multiple Access Method The wireless TD-L
