Wi-Fi offload performance will be greatly improved. In the face of the mobile data traffic that is about to increase by a thousand times, telecom operators and chip operators are all committed to the development of Wi-Fi offload technology, and plans to implement a new generation of integrated 802.11ac and 802.11ad solutions in 2014 to further expand bandwidth and signals. Coverage.
Wi-Fi chip is designed for low power consumption and high integration
Looking back at the development of the Wi-Fi market in 2013, we can see that Wi-Fi data traffic has also reached a new high due to the huge growth of mobile broadband data transmission. In the future, as mobile devices continue to increase data demand, such as increasing penetration of smart phones, increased mobile computing and a surge in Internet of Things, Wi-Fi data traffic will continue to skyrocket.
The amount of mobile data will increase by a thousand times, and the Wi-Fi shunt technology will accelerate its rise.
Not only that, but the data usage of each device will also increase as consumers increasingly rely on mobile devices and IoT services. For example, Cisco's statistics show that in 2011, the average data usage of smartphones nearly tripled, reaching 150MB per month, compared to 55MB per month in 2010. In addition, in 2011, mobile data traffic generated by general smart phones was 35 times that of general basic function phones. Therefore, the industry is preparing to increase mobile data traffic by up to a thousand times.
Faced with a thousand-fold increase in traffic, the carrier's solution is to shift the load of the network to Wi-Fi, which will also bring new challenges to Wi-Fi devices and the market.
On the other hand, the recently popular market for wearable devices will also help the growth of the Wi-Fi market. In the "Qualcomm Uplinq 2013 Developers Conference" on September 4, 2013, Qualcomm released the smart watch Qualcomm Toq. The smart watch is designed to be the second screen of a smart phone. It uses Qualcomm Microsystems (MEMS) Technologies' proprietary Mirasol display technology to provide a watch-ready experience at all times, and is available via Qualcomm WiPower technology. Wireless charging and a true stereo Bluetooth audio experience not only provide the wearer with a long-lasting battery, but also seamlessly connect to a smartphone.
As technology matures, wearable products will become a must for mobile device manufacturers in 2014. It will also bring new mobile experiences to consumers and bring new data traffic demands to mobile networks. Wi-Fi offloading technology will also be more critical.
Wearable products are widely released, Wi-Fi hotspots are built to heat up
Looking forward to 2014, Wi-Fi will help to divert the huge data traffic load of mobile networks and connect with 3G/4G more closely, which will bring key kinetic energy to the growth of Wi-Fi market. The coverage of 3G/4G and Wi-Fi small base station infrastructure will cost-effectively enhance the use of Wi-Fi in 3G/4G environments.
Seamless access to Wi-Fi hotspots has been achieved through support for Passpoint, the Wi-Fi Alliance's Hotspot 2.0 authentication technology that enables easy, secure and seamless access through automatic detection and selection. Wi-Fi networks, and even Passpoint authentication, can be based on 3G/4G credentials, an example of a tighter interconnection between 3G/4G and Wi-Fi.
Wi-Fi traffic removal is more important 802.11ac/ad joins the shunt work
In the future, in order to make full use of all spectrum, the industry must eventually combine data streams from Wi-Fi and 3G/4G, so indoor Wi-Fi network positioning will become the main differentiating factor between operators. Currently, relevant industry players are already developing reference designs and software to achieve better hardware and software integration for 3G/4G coverage in Wi-Fi small base stations.
In fact, the latest 802.11ac and 802.11ad technologies will also join the 3G/4G network traffic offload in 2014. 802.11ac is implemented in the 5GHz band, bringing two major enhancements to 802.11n. The first enhancement is to use a wider channel bandwidth. 802.11ac uses 80MHz and 160MHz channels, and the data transfer rate and capacity can be two to four times that of 802.11n.
The second enhancement is a mode of operation called Multi-User Multiple Input Multiple Output (MulTI-User MIMO) that allows Wi-Fi Access Points (APs) to simultaneously serve multiple simple clients, such as mobile phones. This is achieved by using multiple transmit antennas to simultaneously direct different data streams to different users, similar to the mode in which multiple simple clients of a mobile phone system communicate.
802.11ad operates in the 60 GHz band. Such a wide channel can provide data transmission rates of more than 6 Gbit/s. However, the signal at this frequency does not penetrate the wall and must be bounced around to pass through obstacles in the room. 802.11ac will be the next step in Wi-Fi, not only with higher data transfer rates and capacity, but also by enabling a large group of small, low-power, simple devices, such as handheld devices, to make Wi-Fi work more like a hive. System. 802.11ad has a very high data transfer rate, but the transmission range is common. Docking is a possible application. For example, a handheld device can be connected to a computer screen or a television for use as a computer or home entertainment system.
Wi-Fi chip is designed for low power consumption and high integration
Wi-Fi chip design will also be different for the mobile device market in 2014, such as low cost, miniaturization, longer battery life, and the addition of Wi-Fi positioning and IoT software. The main trends in Wi-Fi chip design in 2014 include low power consumption and support for flexible software for higher-level integration.
In addition, in order to better integrate Wi-Fi and 3G/4G technologies to achieve better data removal, 3G/4G and Wi-Fi aggregation small base station solutions will also be an important design trend for Wi-Fi chips.
