"4G +" has gradually become a standard business schedule for carriers

Nowadays, "4G +" has become a standard for operators. So what is 4G +? That is, the LTE-A, that is, the use of carrier aggregation (CarrierAggregation, GA) technology, can make 4G network speed faster. If we compare a 4G network to a road, carrier aggregation is like widening several single-line lanes.

According to data released by GSA, as of July, 88 carriers in 45 countries around the world had deployed the "4G +" carrier aggregation technology, accounting for about 422 of the world's 4G operators (20%, more than 40 carriers are preparing.

According to a report released by StrategyAnalytics, carrier aggregation is expected to become a standard configuration for carrier networks in the next few years. analysts predict that: "in 2016, China will become the world's largest producer and consumer of 'carrier aggregator' terminals."

At present, the three major operators have issued the related "4G +" Development Strategy and began to use it commercially.

China Telecom: 4G + service is available in 40-50 cities in the second half of this year

At this year's "Tianyi mobile phone fair", China Telecom officially proposed "Tianyi 4G +", which uses the 4G/LTE carrier aggregation technology, by aggregating carriers in multiple LTE frequencies, the peak download rate of mobile phones can reach 300 Mbps, which is twice the single-carrier (4G) speed, the uplink peak speed can reach 50 Mbps, which is twice faster than that of 4G. It is reported that the current peak FDD rate is 150 Mbps, TDD peak rate is 100 Mbps.

In August this year, China Telecom started the "Four G + Tianyi" business in 17 cities, providing users with a higher speed and richer service experience, at the same time, more than 20 cost-effective mobile phones and high-end stars, such as the "Four G + Tianyi" mobile phone and the "Four G + Tianyi" package and preferential policies, are also listed on the market.

China Telecom plans to launch 4G + services in major cities (40-50 cities) in the second half of this year.

China Mobile: Build 60 thousand base stations before the end of the year

Li zhengmao, Vice President of China Mobile, also revealed that China Mobile is constantly improving network performance, "has implemented LTE-A carrier aggregation technology in 4G networks, many hot spots have achieved a maximum rate of 220 Mbps, three-carrier aggregation is being tested in some cities, with a speed of 330 Mbps. ".

It has been commercially available in Guangdong, Shanghai, Jiangsu, Zhejiang, and other regions. Its Downstream peak speed exceeds 200 Mbps, providing customers with a high-speed and smooth network experience.

It was reported that China Mobile planned to invest 4G + by the end of this year when provincial companies invested 4G in the construction, hoping to build 60 thousand base stations by the end of the year, 6% of the total 4G investment.

Jiangsu Mobile started the deployment of "4G +" in June this year, doubling the 4G network speed. As of September, the 4G + network coverage of all colleges and universities in the province has been completed, and the 4G + network deployment of core business areas and 7000 enterprises and enterprises in the province is underway. According to the latest news, "4G +" HD voice has been first available in Nanjing, Suzhou and Wuxi since yesterday. By the end of this year, it will be commercially available throughout the province.

As early as this year's GSMA conference, Shanghai Mobile also released the "4G +" service, which is planned to be fully rolled out from the second half of the year. The new carrier aggregation technology, an important part of the 4G + evolution technology (LTE-A), doubles the speed of access. The peak download speed ranges from 220 Mbps to 330 Mbps, and the maximum peak value is Mbps.

As a carrier aggregation Demonstration Area in Jingan, Changning, and People's Square, Shanghai mobile has deployed dual-carrier aggregation and tri-carrier aggregation.

With the commercialization of the 4G + business, China Mobile is expected to support 22 4G + mobile phones by the end of the year.

China Unicom: Three-carrier aggregation commercialization in 2016

China Unicom released a new-generation network architecture white paper at a communications exhibition held recently. Lu Yimin, general manager of China Unicom, announced that the network would accelerate the deployment of "4G +" and increase the network peak speed to 300 M. It also said that the three-carrier aggregation was commercially available in 2016, and the peak network rate was increased to 330 M. In the future, we will also actively promote the large-scale deployment of three-carrier, four-carrier, multi-carrier, 4G and Wi-Fi convergence.

Guangdong Unicom took the lead in responding, and is expected to invest 5 billion yuan in the next year to build a "4G +" superzhuo network. According to the feixiang network reporter, the 4G + network technology currently being built by Guangdong Unicom has achieved amazing network speeds. After field tests, the peak rate is as high as 370 Mbps.

Currently, Guangdong Unicom has built a m high-quality 4G network covering urban areas, county towns, towns and administrative villages. In, Guangdong Unicom will achieve a m high-speed 4G + coverage, with m high-speed network deployed in the Pearl River Delta, in, the province deployed the-m high-speed network. Creating a "4G +" urban agglomeration brings users a better mobile Internet life and service experience.
