DR-7800 can be ideally used for HF email, for example, over the Winlink network. Externally, it stands out due to its high-resolution OLED display which, among other things, can be configured for waterfall and spectral views. Thanks to its reliability and low power consumption of 3 W, the new modem is also well-suited for distress radio communications and other applications under severe conditions.

Delay-tolerant networking - Wikipedia

See also rfc4838 & rfc5050

Delay-tolerant networking (DTN) is an approach to computer networkarchitecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.

Spectral efficiency - Wikipedia, the free encyclopedia

Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the media access control (the channel access protocol).^[1]

5G announcement by FCC

What is key here is unlicensed use of wifi channels.

5G (5th generation mobile networks or 5th generation wireless systems) denotes the proposed next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G planning includes Internet connection speeds faster than current 4G, and other improvements.

The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks:^[1]

• Data rates of tens of megabits per second for tens of thousands of users
• 1 Gb per second simultaneously to many workers on the same office floor
• Several hundreds of thousands of simultaneous connections for massive wireless sensor network
• Spectral efficiency significantly enhanced compared to 4G
• Coverage improved
• Signalling efficiency enhanced
• Latency reduced significantly compared to LTE.^[2]
