The existing infrastructure owned / closely shared by telecom (wireless)
operators and submarine / terrestrial cable networks might be
under-utilized or sub-optimally utilized in different parts of the world.
This is also true of space missions, which at least increasingly share
payloads, but here again, the equipments tends to be dedicated to imaging,
satellite telephony, broadcasting, Internet etc. Leaving satellites aside,
if we focus on cables, network computers and PtP towers and equipment, the
resources could be better shared, between operators, not only between the
major telecom operators, but also between content networks, IXPs, Community
Networks, and other major captive users such as a large University campus
or a Government / military organization.

Spectrum sharing models could help the present licensees resell unused
Spectrum, but some technologies and standards may have to be developed to
enable licence holders use the assigned spectrum much the same way as
submarine cable divides data streams between transmissions.

The Convergence of technologies is not only about converging voice and data
(phone and computer), but also broadcasting.  Could the IETF pay attention
to the possibilities of merging tower technologies for phone, IP Telephone,
Data, Radio and Television Broadcast, Two way Radio, Satellite Telephony
(whatever is technically feasible) and also recommend standards for
equipment at the user's end, to make the phone double up as a two way radio
(for use in emergency situations where a sim card may not work) and to make
the cellular phone work as a satellite phone?

Another idea would be to build in the capabilities for a low power
emergency / always-on-for-all-for-a-lifetime Internet (say at 144 kbps)
which will work free of cellular towers anywhere in the everyday mobile
phone and correspondingly determine an architecture and infrastructure that
would co-exist with the Gigabit Internet.

IETF / IRTF could work on synthesizing past and recent technologies to help
develop Community Networks, with features that do not exist in a system of
tense separation between the phone companies and Internet networks.

IETF could also break down the components of the 5G bundle, identify
components (for example 1-20 GBPS bandwidth, the advances in P2P
technologies etc) and determine what components are achievable independent
of the 5G bundle, as for instance by building equipment based on 802.11 ac
etc., and recommend open standards that match or surpass the 5G promises.
