All along, ordinary Internet users and people in the wireless communication industry believe that the launch of 4G5G will make WiFi extinct, especially the recent 5G is promoted by Qualcomm as a strategic product, coupled with the help of operators. In fact, everyone has forgotten that the development of mobile communications is driving the development of near-field wireless communications. They are not enemies.
Three stages of development of WiFi
The development of WiFi is divided into three phases. The first phase is considered to be from 2000 to 2007, and the first phase is the era of computers and networks. The second outbreak was from 2007 and 2008 until around 2013, and that was the application of smartphones. The third big outbreak is the future of a considerable length after 2013. The intelligence from smart homes and even other aspects is equal to the application of the Internet of Things. We also mentioned the automotive industry. The first and second China Commercial WiFi Summits hosted by Meng Technology and the Baima Lake Summit were also held behind the rapid development of this industry.
As an important part of mobile Internet technology, WiFi technology is still booming, starting from the popularity of 802.11n technology to the commercialization of 802.11ac. In the era of 802.11ac, the downlink bandwidth of APs has even surpassed the speed of LANs, and the products that have been commercialized have reached an astonishing 1.3 Gbps.
A review of love history: challenges in the early stages of 3G operations
In the 3G era, in order to alleviate the pressure on the network, domestic operators have invested heavily in building a carrier-grade WiFi network. Up to now, China Mobile has deployed more than 4 million APs, and China Telecom has deployed more than 1 million APs as 3G. Unicom's most stress-free China Unicom has a total of more than 400,000 APs. These WIFI networks deployed by operators have alleviated the pressure on the network while cultivating the habit of using hundreds of millions of users to use WiFi.
Nowadays, the WiFi module has become the standard configuration of intelligent terminals. The WiFiI network has become the main bearing force of the mobile Internet data. The low-cost and universal characteristics of the WiFi technology will be complemented by the 4G network under the operator's large-scale operation. Continue to play its value.
In the 456G era, WiFi still has its place.
Nowadays, the focus of operators' WiFi network construction has gradually shifted from the hotspots and hotspots of public coverage such as campuses and public buildings to outdoor hotspots and government and enterprise applications. The construction mode of the WiFi network has gradually shifted from the previous investment-type construction demand to the profit-oriented ICT construction model.
According to the WiFi industry's full media technology, in many ICT projects, such as bus stop signs, buses, cruise ships, scenic spots and other scenarios have wireless Internet access, but in the past, a single mobile communication network or WiFi wireless coverage The wireless access problem of the mobile carrier cannot be solved well. The root cause is that the link backhaul channel is difficult to establish in the mobile scenario or the mobile network backhaul rate is too low (3G) to make the experience poor.
For example, Shanghai Yuchuang has launched wireless communication products for a variety of scenarios, using over-the-range WiFi technology and supporting wireless MESH networking technology. The company also fully integrates WiFi and TD-LTE technologies and has launched a variety of LTE terminals, including: LTE-MiFi (personal handheld terminal), field-based LTEFi terminal, vehicle-mounted LTEFi terminal, and LTE CPE. Applicable to a variety of application scenarios, office buildings, homes, outdoor venues, mobile vehicles (bus, light rail, etc.), allowing users to easily enjoy LTE networks through WiFi. All terminals can be centrally managed and controlled via AC (Enhanced Wireless Network Controller).
Opinion: A good pair of friends who have developed together
From the perspective of China's 3G market in the future, voice services will not help mobile operators to increase revenue, and because of the increase in the number of mobile operators, the ARPU brought by voice services will inevitably decline. Therefore, providing more data multimedia services will help the mobile operators to maintain user loyalty, improve network utilization, increase service added value, and maximize profits. This is also the pre-deployment of 3G operators. The issues that must be considered. In contrast, with the joint promotion of chip manufacturers, PC manufacturers, WiFi alliance members, and operators, WLAN has made substantial progress in deployment.
From the aspects of coverage, transmission rate, basic service category, mobile speed, forward expansion, evolution and other aspects, 3G4G and WiFi are not a competitive relationship that can replace each other, but a complementary relationship that can foster strengths and avoid weaknesses.
