We all know that the
African telecoms market has made huge – and exciting - progress over the last
few years; sub-sea capacity probably now exceeds current demand, competition
(not necessarily capacity) has brought about a rapid crash in prices and
terrestrial fibre networks are being built.
Looking into the future
we see a host of possibilities and challenges which will impact on each other:
- FTTH, WIMAX, LTE and ADSL networks will continue
to be built and local loop unbundling will also hopefully start
- The investment in high speed last mile connectivity
will drive growth in subscribers. More
subscribers, using services based around high-speed content, should drive
down the cost per Mbps and drive further subscriber growth
- There will be more investment in terrestrial
trunk routes and both national backhaul and cross border links will grow
by business cases
- Interconnection will be one of the hot topics
with different businesses adopting different strategies.
Interconnection strategies
Today in Africa, we have
some cross-border connections that are mostly selling commercial transit to
countries with no landing stations.
However, most African Internet traffic routing is between partially terrestrially
connected Africa and in most cases the African Internet is just connecting
Africa to Europe.
Landlocked countries are
often taking terrestrial backhaul straight to the nearest cable landing
station. Very little content is hosted in Africa though some content is cached
regionally.
However, as cross-border
traffic increases different types of operators have – and will – adopt one of
four strategies:
The National incumbent Telco or PTO may have connection to borders where it
interconnects to a similar entity in a neighbouring country but its network
almost certainly stops at its own border.
Its cross-border
connection may be used for voice, IPLC half circuit and OSS, maybe to sell Internet
transit or buy Internet transit from its neighbour. The problems with such
connections are lack of SLA and the use of different operator networks mean
that there are unlikely to be any SLA or QoS guarantees.
Pan-African Operators – like the MNO Groups, Academic Networks
etc
These companies will
have sizeable bandwidth needs and a national network in a number of countries
that are not necessarily bordering. As
they will have made substantial investments in subsea capacity at a group level,
they will link their networks to a Pan African network, aggregating and hubbing
the purchased sub-sea capacity at strategic landing points.
Independent SNO or ISP
These entrepreneurial
companies are more focused on last mile and customer acquisition than long distance
infrastructure projects though they may have business customers needing
international private VPNs.
They will usually
interconnect via existing backhaul networks or satellite.
Cross-border operators like Liquid Telecom
Independent wholesale
carrier Liquid Telecom has built a fibre network that crosses multiple borders
in Southern Africa. We are servicing the
needs of operators of all shapes and sizes providing connectivity to support
enterprise, home user and rural broadband customers. Liquid’s approach is far-sighted and its
goal is to keep African traffic in Africa.
The Future
One thing we know for
sure is that the Internet won’t develop according to any kind of co-ordinated
plan. This would be impossible given the
number of operators and countries involved.
However, we can be sure that, thanks to market forces, broadband will
end up being affordable to the majority of residents and businesses.
At Liquid we are aiming
for a future that is likely to consist of a diverse connected network. Terrestrial
backhaul links will be complete and used to develop networks. Much more content
will be produced and hosted in Africa leading to the need for greater
interconnection.
About Liquid Telecom www.liquidtelecom.com
Liquid Telecom has built
the largest fibre network in Southern Africa providing backhaul between most urban areas and last mile connectivity in the main
cities of Zambia, Zimbabwe, Botswana, Lesotho and South Africa.
Liquid’s network is the first to cross country borders and covers some of the
most challenging parts of the world where no fixed network has existed
before. It operates as a wholesale carrier in all five countries as
well as an operator in Zambia and Zimbabwe.
