When our cell phone signal continuously from 2G, 3G, and 4G network switch when the operators but also a "4G+" concept, and 5G, and is said to be in full swing. In the operator-user 4G under the network marketing, 4G network is not a taste, again a "4G+" users feel cluttered? " 4G+ "what exactly is a ghost? why do carriers also sell" 4G+ "? this article do some analysis for reference. 20 billion didn t play burn games Baidu technology
First, "4G+" what is it?
China Telecom: for 3 days of "2015 days wing Terminal trading Expo cum peak Forum" Yu July 3, 2015 in Nanjing opening, this times Assembly Shang, China Telecom official foreign released "days wing 4G+" brand, "days wing 4G+" is China Telecom in original days wing 4G network of based Shang, application carrier aggregate technology (CarrierAggregation, referred to CA), sharply upgrade network uplink and down rate and build of business brand, Its downlink peak rates of up to 300Mbps, uplink peak speeds of up to 50Mbps, 1 time times faster than 4G. Starting from August 1, "Tian Yi 4G+" business will be commercial use, users can experience the faster network in key cities nationwide service.
China Mobile: 2015-the Mobile World Congress in Shanghai on July 15 at the Shanghai New International Expo Centre, Shanghai mobile during release "4G+" service plans in full swing in the second half. Using "4G+" evolution (LTE-A)--an important component of the new carrier aggregation technology, Internet speed will achieve the double. Peak download rates from 110Mbps to 220Mbps, maximum up to 330Mbps. It is reported that the people's square in Jinan, changning, and regional carrier aggregation model, complete dual-carrier aggregation and deployment of three carrier aggregation. Meanwhile, also raised prices of a number of initiatives.
China Unicom: "4G+" concept yet proposed. Follow or not to follow up? should be followed up.
In fact, "4G+" or 4G, "+" is accelerating, a simple analogy is that highway widened more. There'd be something else, not very clear.
Er, operator why tore open at the 4G speed problem?
Try a few reasons, as follows:
1, fashion. "The Internet +" after the concept, based on the original concept of a "+" sign and concept was immediately lifted, then is the meaning extension and expansion. Therefore, "4G+" in 4G, there is a certain conceptual distinctions.
2, China Mobile with 4G of first-mover advantage, first half of the year, has scored 190 million users, gaining momentum. 3G in contrast, China Telecom and China Unicom, fell for a few months in the first half. 4G business licences, when three operators in 4G network speed to be enough articles, network speed good or bad constantly repeated. "4G+" tore open at the speed once again, seems to be on the Web there is no better topic can tear.
3, is a positive response to the State Council on acceleration reduced tariff initiatives. Speed network theory has been further improved, postage rates will continue to fall during the year. Have already suggested a "4G+" operators, reduce speed as an advocacy focus.
Third, user: "4G+" faster than 4G, but isn't it a little egg?
To the user, "4G+" speed is several times that of the 4G, good or bad? the problem discussion for a long time. In General, the problem of operator services, or a speed can solve. Most points of interest in addition to speed, there is total consumption of network security and for network (not just the tariff prices).
Once mentioned, network speed is an issue, for the average user, not a professional gun tools, in terms of experience, 3G and 4G there is a clear feeling, while the same is 4G, in the case of network coverage and other differences, the speed difference is difficult to perceive. Therefore, pile those technical terms, like different planets.
Network security issues, in addition to the network layer security, by means of an application layer and Terminal layer, there are many secure ways. User-oriented, network security can be user to switch to 4G network selling point, that's the problem. "4G+" and 4G do not see any difference.
Network consumption related to charges, is the most sensitive for the user. Faster is better, many hard budget constraint for users of network consumption, apparently not. Although charges unit price is declining, but due to the speed, will cause an increase in absolute volume of consumption. For users there is consumer confusion, users have to pay the additional price for used more.
Therefore, "4G+" for users, good or bad, it depends on the actual situation of the user. Speed will feel cool Internet consumption, as well as Internet access speed is not willing to pay a certain price will be complaining that the accused more appropriately.
D "4G+", the traffic management more difficult or easier?
Personally agree with some people in the industry argue that carriers flow management is a problem, the key is not a flow management user management. But since the operators have been operating in traffic on the way to go for many years, and companies pay to operate after a period of time. Therefore, "4G+", the traffic management is more difficult or easier? those that are more concerned about the issue. Personally think that "4G+" increases the difficulty of traffic management, or constant speed increases the difficulty of traffic management.
Firstly, the speed-up resulted in traffic price has been in a State of instability, which either for traffic flow figures forward operation or backward operation, on the practical side is a big challenge.
Secondly, from the user's point of view, the long time or monthly is the most beneficial to the user. Now some carriers unlimited unlimited package business, play is a disguised form of monthly results. Faster, even charges unit price declining, but users higher monthly call just. This is the most basic contradictions between the operator and the user.
Third, the "4G+" is proposed, the core of which is the development of 4G users. Operators in order to form 4G as soon as the user scale, intensity increases, which include greater flows of giving concessions. It also increases the difficulty of traffic management. Especially in the exploration phase of traffic management business model challenges even greater.
Finally, data plan larger question about the traffic cleared the more prominent. Executive meeting of the State Council has also put forward a flow can increase, flow is not clear requirements. But for operators, as soon as possible the work flow is not zero is also on the agenda. For traffic management, but also a challenge.
In short, with "4G+" as a representative of network speed, would exacerbate the operator throughout the speed traffic management more difficult. Therefore, the flow of business than business users. A typical scenario is that personal 4G launching soon, will upgrade 4G plan, did not enjoy any privileges. Instead, in order to advance the user 4G, the follow-up being given preferential treatment. This is a very typical non-user business practice, especially for those of us old users. Whether it's 4G, "4G+" or 4.5G, 5G, it is recommended that operators review the so-called traffic management, but more emphasis on user management. Concept, and kept my old user has gone away to your competitors, how is that good?
