Future challenge for military communication –the limited resource frequency spectrum

Frequency spectrum – a limited and scarceresource• The 5G vision
– Networked society andInternet of Things
– Massive number ofdevices
– Requires many newfrequency bands, moreand higher
From: Amy Nordrum, “Popular Internet of ThingsForecast of 50 Billion Devices by 2020 Is Outdated”,IEEE Spectrum, Aug 2016

5G and IoT
• Planned to use considerably higher frequencies– Outdoor environments: frequencies up to about 30 GHz– Indoor: up to about 90 GHz
• In licensed and non-licensed bands• Ongoing activity: to access as much frequency as possible
• Implications on military radar and communication systemsFrom Ericsson White paper, April 2016, 5G radio access

Meanwhile: increased demand of bandwidth formilitary purposes• For robustness
– Jamming threat, interference, mobility,…• For new capacity demanding applications
– Network oriented services: situation awareness, battle management systems,sensor solutions, …
• More radio systems– New services and for interoperability– UHF band: 225-400 MHz is problematic!
• Interference from other radio systems. Difficulties to preserve the robustness forbroadband frequency hopping radio systems
• The existing military frequency band, that is decreasing, will obstruct theintroduction of new valuable radio services!

Conclusions• There will come good communication techniques that will enable new
and valuable high capacity services• BUT, frequency spectrum is a necessity• To ensure frequency spectrum for military communication and radar
services:– Not loose more frequency bands– New and innovative techniques to handle frequency spectrum more efficient
• Aggregation of frequency bands• Dynamic frequency management• Use of higher frequency bands where that is possible• If use of unlicensed bands, increase the robustness with other techniques or
redundant systems
