[kictanet] Shared Spectrum Framework for Community Networks for Kenya online discussion

Mon May 31 10:28:52 EAT 2021

Dear Adam,

Many thanks as always for stirring the conversation, i will attempt to give
some feedback on your feedback. I hope other colleagues can chime in.
Indeed Spectrum has been a very opaque subject and the silence is a
testament to this. Be that as it may , we are at an important phase of
history where we are attempting to move local stakeholders from the
spectrum menu onto the table. My responses are in line

*BO*: In my humble opinion, the problem is lack of sufficient meaningful
and affordable access despite the efforts made by mainstream operators.
Some parts of the country are still unserved and others are underserved.
Community Networks are an attempt at local solutions to local connectivity
challenges. A good example that most of us relate to was shared by Michuki
Mwangi during the Webinar where we pool resources to sink boreholes and
build water networks in the rural areas with the goal of ensuring each
home/household has a decent water supply. Before we sink boherholes
permission is required from the relevant government authorities under the
ministry of water. In the same case, community members can come together
through CBOs or relevant special purpose vehicles and develop frameworks
for ensuring they get meaningful and affordable connectivity.
On the issue of Spectrum I agree with you that there is under-used spectrum
that can be returned to CA after which CA can license someone else to use.
I believe this is what this process is all about. A new license category is
in the office that can take advantage of this unused or underused spectrum.
I believe this is the way the likes of Kameme TV started which broke the
glass ceiling on who could own a TV.

*BO: I agree with your observation on the need for an all encompassing
review of the spectrum framework. My humble opinion though is that we
should not mix the two and should give due attention to the later as you
propose since there might be many factors beyond the current issue premised
around developing a culture of local solutions to local problems. Community
Networks have the potential to spur local development of Network equipment.
Latvia has done well with Mikrotik, China has done well with the Huawei and
Ubiquiti products. I believe Kenya can come up with a local solution in
future using the dormant Gilgil Telecommunication Industries.*

*BO : This is true. A lot of peer support is taking place in the background
to make sure that Community Networks understand the fundamental issues of
connectivity. We are discussing meaningful and affordable connectivity.
Forums such as the Kenya Network Operators Group (www.nog.ke
<http://www.nog.ke>) have been very helpful on this front hosting panels
that reflect on Infrastructure investments and the business case for the
same.*

*BO: Agreed. This is a factor of capacity building. The Communications
Authority has Regional Offices that I believe can assist in equipping
Community Network and other operators with ample knowledge on spectrum
utilization and management.*

*BO : I agree with your observations. It would be good to have feedback
from the Communications Authority on the results of the trials that were
done ny Mawingu Networks and Strathmore University with respect to the use
of TV White Space.*

*BO: Agreed. As a matter of fact, we have so many homegrown Customer
Relationship Management Solutions that have been developed to respond to
the needs of the Sambaza culture in our mtaas. This is the beauty of
Community Networks*

*BO : I agree there is need for more spectrum for mobile. I equally think
there is need for more spectrum for wi-fi since it the preferred mode of
access in the rural areas. I would prefer an evidence based approach to
this issue.*

*BO : Agreed. This issue has come up for discussion during the Community
Networks panel on the Kenya Network Operators Group. Community members are
already aware of the punitive steps that CA takes when there is
interference. I beleive there is need to create more awareness around this
issue to deter such occurrences.*
