Nigerian Communications Commission Develops Draft Guidelines For Use Of TV White Spaces In Nigeria

Regulation & Policy

The Nigerian Communications Commission (NCC), has developed draft guidelines for the use of Television White Spaces (TVWS) for rural broadband connectivity in Nigeria.

The apex regulatory body in charge of Nigeria’s communications sector said it developed the guidelines in conjunction with the National Broadcasting Commission (NBC), the country’s broadcast regulator, and it is currently consulting with industry stakeholders to present the final guidelines.

According to the draft document made available to the public, NCC defines Television Whitespaces as the “unassigned spectrum between broadcast television channels in the 470 to 694 MHz portion of the UHF frequency band possibly utilised to provide Internet access to the underserved and unserved regions of the country, mostly in rural service areas at broadband speeds”.

“The guidelines provide a framework to enable license-exempt transmitters to operate in the UHF band, which are allocated on a primary basis to the broadcast television service, on frequencies and at locations where the spectrum is either not assigned to licensed services or not in use at particular times while protecting primary users from receiving harmful interference,” the document reads in part.

TVWS utilise vacant, unused or interleaved frequencies of inactive channels (known as buffer channels) to provide high-speed broadband internet to homes. In the past, buffer channels were placed between active TV channels to protect broadcasts from interference. Recent developments in technology and research have proven that the unused spectrum of buffer channels can be used to provide broadband internet access while operating harmoniously with surrounding TV channels.

Since the famous pilot test of TVWS technologies in Cambridge in 2011 by a consortium comprising of Microsoft, BBC, Nokia, Samsung and six other allies, TVWS is growing to become a notable emerging technology in the quest to bridge the digital divide and connect the unconnected especially in remote communities around the world.

In Africa, the technology has undergone some pilot projects, especially in South Africa where more than ten schools connect to broadband internet service at a browsing internet speed of 4 Mbps using inactive UHF spectrum meant for TV broadcasting service. The emerging technology has also undergone tests in Kenya, Malawi, Nigeria and Tanzania.

In August 2019,   the U.S. Trade and Development Agency awarded a grant to South Africa’s Wireless Access Providers Association (WAPA) to deploy three TVWS network builds and develop a business plan. These were to help ISPs and their investors understand and take advantage of commercial opportunities with TVWS. Adaptrum led the project in collaboration with a consortium of U.S and South African partners, including Microsoft, International Data Corporation and Project Isizwe.

The success of the TVWS test pilots in Africa has been attributed to its capability to travel up to 10 kilometres in radius, which is great for the continent’s vast remote, off-the-grid villages. Major technological advancements in TVWS has been focused on its application in rural communities, with Africa hosting a large area of the target market. Read the full article on Space in Africa here
