IEEE is a non-profit scientific organization that brings together scientists and engineers worldwide specializing in research and sharing of technological insights to benefit humanity. A major achievement of IEEE is the development of the 802 standard for LAN, which is applied worldwide. And recently, IEEE made a "shocking" announcement: they have successfully researched and developed the 802.22 standard, enabling "super wifi" broadcasts with a coverage range of over 100 km. 802.22 Technology Standard According to this technology standard, IEEE promises that devices can still achieve a bandwidth of 22Mbps at distances over 100km. Engineers have focused on researching frequency bands ranging from 54GHz to 862GHz, which are known to be the UHF and VHF radio wave channels.
This technology standard was approved by the US Federal Communications Commission (FCC) in September 2010. As of now, this technology standard has been implemented in the UK, US, and Japan in rural, remote, and isolated areas to provide internet services to all parts of the country.

Potential of IEEE 802.22 Technology Standard in Vietnam
1. Coverage Range: Due to environmental factors and infrastructure not yet matching developed countries, the coverage radius of the 802.22 standard in Vietnam is only 33 km, capable of serving 1.25 people/km². Compared to other standards like Wimax with a coverage range of 1 to 5 km; LTE is 0.3 to 5 km, this standard is far superior.Thus, with its wide coverage area, no line-of-sight requirement, and no complex infrastructure, the IEEE 802.22 standard system is a potential solution for widespread internet access in rural, border, and island areas of Vietnam.2. Data Speed: With devices in Vietnam's climate, the bandwidth of this technology standard will reach 384 Kbps to 1.5 Mbps depending on the location. With this speed, rural areas can still meet the needs of reading newspapers, browsing the web, and quickly updating hot news about society and science-technology...
3. Service Support Capability: The WRAN 802.22 standard can support real-time (IPv4) and non-real-time (IPv6) services. It can flexibly switch between these two services. Additionally, the WRAN standard is compatible with other communication network systems and can provide Wi-Fi hotspots to extend its operating range.
>>>Refer to the best Wi-Fi routers on the market today at:2 . So với các chuẩn khác như Wimax có tầm phủ sóng 1 đến 5 Km; LTE là 0.3 đến 5 Km thì chuẩn này vượt trội hơn hẳn.
Như vậy với tầm vùng phủ sóng rộng lới, không yêu cầu tầm nhìn cũng như các cơ cở hạ tầng phức tạp thì hệ thống chuẩn IEE 802.22 chính là giải pháp tiềm năng để phổ cập mạng internet tại các vùng nông thôn, bên giới, hải đảo... tại Việt Nam
2. Tốc độ dữ liệu: Với các thiết bị mà thời tiết tại Việt Nam thì băng thông của chuẩn công nghệ này sẽ đạt 384 Kbps đến 1.5 Mbps tùy vào vị trí. Với tốc độ này tại vùng nông thôn vẫn có thể đáp ứng đủ nhu cầu đọc báo và lướt web, cập nhật nhanh các tin tức nóng hỏi về xã hội - khoa học kỹ thuật...
3. Khả năng hỗ trợ dịch vụ: Chuẩn WRAN 802.22 có khả năng hỗ trợ dịch vụ thời gian thực (IPv4) và phi thời gian thực (IPv6). Linh hoạt chuyển đổi giữ 2 dịch vụ trên, ngoài ra chuẩn WRAN còn tương thích với các hệ thống mạng truyền thông khác, khả năng cung cấp Hotspot wifi mở rộng phạm vi hoạt động.

Some points to consider when implementing WRAN 802.22 standard
1.The frequency bands between two UHF and VHF channels need to be liberated and reused.
2.More thorough research should be conducted and standards and regulations issued in Vietnam to ensure uniformity among devices, helping future devices to be compatible with the system in the best way.
3.A specific development plan is needed, establishing a map for the construction of transmission stations to avoid interference with other areas.
Conclusion
With the outstanding development of current technology, we must calculate carefully and make the most optimal plans for network service development. More specifically with the WRAN 802.22 standard, competent authorities and network operators must have a broad perspective and make the most accurate decisions.
