Spectrum below 6GHz
Wider coverage allowing cost effective delivery of mobile services
Bandwidths considerably wider (in the order of 100s of MHz) than those of today, providing a combination of capacity and coverage
New bands below 6GHz should be made available for 5G
Spectrum above 6GHz
Needed for applications requiring extremely high data rates
May accommodate wider channel bandwidths (e.g. up to 1GHz per MNO) within a coverage area that may reach 100s meters
Propagation characteristics may lead to higher spectrum reuse and may facilitate sharing with existing services
5G NEEDS SPECTRUM BELOW AND ABOVE 6GHZ
Higher and lower frequencies are both needed to meet multiple use case scenarios

700 MHz
LTE networks already deployed on this band in some countries, including Australia, New Zealand, Japan
European Commission legislative proposal (Feb.16) for a common schedule for making the band effectively available for wireless broadband by 2020
Substantial benefits for 5G if made available before 2020 with a coordinated approach
470-694 MHz
For 5G deployment in longer term
IMT identification in a number of countries during WRC-15
Region 2: 470-608 & 614-698 MHz: Bahamas, Barbados, Canada, Mexico, U.S.; 614-698 MHz: Belize, Colombia
Region 3: 470-698 MHz: Micronesia, Solomon, Tuvalu, Vanuatu; 610-698 MHz: Bangladesh, Maldives, New Zealand
Added to the preliminary agenda for WRC-23 for Region 1
SPECTRUM BELOW 6GHZ UHF
Below 1GHz spectrum can cost effectively address 5G usecases for IoT which have lower bandwidth requirements but demanding good coverage

Adequate economies of scale for cost effective solutions for end users
Global roaming for end user devices
Reduced efforts in cross border coordination
Reduced equipment design complexity, preserving battery life, and improving efficiency in spectrum use
There may be challenges in the Implementation of multiple sets of radio components to support non-contiguous bands (above 6GHz) in the same device in the initial stage especially
SPECTRUM ABOVE 6 GHZ SPECTRUM HARMONIZATION
Spectrum harmonization remains important for the development of IMT as it allows for:
Spectrum harmonization is even more important for higher frequencies
In order to support the development of the new ecosystem for them.

Indoor penetration loss increases with higher frequency
Some indoor penetration through windows
No penetration through concrete walls
Indoor cells will be needed at cm and mm waves

5G DEVELOPMENT: PROTOTYPE AND TRIALS BY GSA MEMBERS

5G will provide new applications together with much enhanced user experiences
5G: a common network platform to enable ICT transformation serving multiple industry sectors
requirements to communications
Global harmonization of spectrum for 5G continues being a very key factor for the success of
mobile communications
5G needs both higher and lower frequencies bands to meet multiple use case scenarios
GSA Spectrum Group is willing to cooperate with administration and regulators as well as our
partners to achieve the goal of a sustainable and successful development of 5G
