The new generation of Wi-Fi is ahead of 5G and begins to be implemented | Technology


While it is expected from next year the arrival of the promised mobile 5G, which will multiply by 10 the standard speed of the current system, the sixth generation wifi has already started. Manufacturers have begun to market the routers prepared for the new wireless connection standard (802.11 ax) and the companies of technological devices prepare their products for a system that provides more security, more speed and more density in traffic, among other advantages. Samsung has opened the gap with the Galaxy S10, already prepared for the new era. Huawei has joined the Korean company.

"It's like a highway with more lanes and where we can get more vehicles and bigger," explains Jesus Yanes, director of New Business for Spain of lto Taiwanese company for the development of connectivity solutions EnGenius.

The 5G, the mobile vanguard, will not replace the wireless connection. Quite the opposite. "The new generation of telephony and wifi they are two complementary vertices of the triangle of technology, "says Federico Ruiz, head of the 5G National Observatory.

The new technology is fundamental to the hegemony of the wireless connection in our lives. According to the Cisco report Mobile Visual Networking Index, in 2022, global fixed and mobile Internet traffic will be 29% wired, 51% by wifi and 20% by mobile. In Spain, the forecast is higher: 24% wired, 64% wifi and 12% mobile.

Cisco has taken to the recent Mobile World Congres its gateway for wifi 6. "The new wireless standard can offer three to four times the performance of the previous standards, latency less than milliseconds and the support of up to 70 devices per 100 square meters, "says the company.

Compatible with our current equipment

The arrival of wifi6 does not require modifying domestic or business equipment, as it is compatible with current devices, although the new technology will be more efficient if the terminal is ready.

WiFi 6 will allow transmission speeds of 1Gb in the 2.4Ghz band and up to 4.8Gb in the 5Ghz band (with eight simultaneous transmissions available). In addition to faster, will have more capacity: up to 10 Gbps up, between three and four times higher than current systems. The transmission of audiovisual data will be especially benefited.

Another advantage is the highest traffic density that supports, a relevant aspect in a society where more and more devices are connected simultaneously and where the Internet of Things (IoT) multiplies the needs. By 2022, there will be more than 12,000 million devices and IoT connections (compared to 9,000 million posted in 2017). In 2022, mobile networks will support more than 8,000 million personal devices and 4,000 million IoT connections, according to the report of Cisco.

The centers of great affluence, the first

Although in domestic environments the current protocol is sufficient for an average family, the greater capacity of users and connected devices simultaneously is fundamental for environments such as schools, companies, stations, airports, hotels or shopping centers, which are the first entities that have begun to incorporate new generation access points. "With current technology, quality is not guaranteed on all occasions," warns Yanes. Within a year it is not expected that this technology will begin to generalize in the particular field.

The new protocol also improves the management of users and the information they send or receive. The incorporation of Orthogonal Frequency-Division Multiple Access technology (OFDMA) allows a shorter response time to the connection demand when there are many users trying to access a Wi-Fi hotspot, greater stability against interference, and safer, higher quality transmissions and capacity. According to the EnGenius executive, "they are able to determine the importance of information and generate intelligent packages that do not collapse the network."

TO the greatest security of the new protocol, even with weak passwords, thanks to the incorporation of the third update of Wi-Fi Protected Access (WPA3), joins a lower energy consumption of connected devices. "The access points communicate with each other to connect a moving user (Band Service Set or Color BSS) and it is the router that tells the mobile that new information is available without it having to search periodically. It will wake him up, "explains Yanes.
