Digital Dividend in Africa
Elizabeth Migwalla On Behalf of the GSM Association

Brief History of the GSMA
Founded in 1987 by 15 operators committed to the joint development of a cross border digital system for mobile communications Became the global trade group for the mobile industry, representing the vast majority of mobile phone networks across the world Now encompassing commercial, public policy and technical initiatives, ensuring mobile services work globally The Association’s members now serve more than 3.5 billion customers More than 750 operator Members across 218 countries Over 200 Associate Members (manufacturers and suppliers) For those of you that do not know, I will give a bit of background on the GSM Association. Originally founded in 1987, the GSM Association has become the global trade group of the mobile industry representing a very high percentage of mobile operators in the world. . . and more than 3.5 billion consumers who they represent. The GSMA has 750 operator members, and over 200 associate members, of which Qualcomm is one.

This has seen our service offering rise from simple voice, to a wider number of data services. Importantly, with the advent of HSPA, HSPA + and now LTE, we are able to offer video.

Broadcast and Broadband
Video over the internet is a well-established phenomena YouTube and other social media sites drive video-over-internet usage BBC iPlayer has huge and growing usage 115m downloads December 2009 120m downloads January 2010 Broadband also has a big role to play in niche TV distribution The headline relationships between broadcast and broadband are well known. Social media sites have created a huge market for short video clips, but traditional broadcasters are also using the internet as an alternative means of distributing content. Broadcasters such as the BBC in the UK have realised that, instead of endlessly repeating content on alternative DTT channels, it would be a more efficient use of the UK’s airwaves to make content available on the internet for one week after the live DTT broadcast. Use of its iPlayer service is rapidly growing. However, broadband also has a role to play for the smaller, niche channels . . .

Broadband and the Multi-Channel Environment
Research from Europe as DTV started to mature (2008) Both UK and France cases show heavy tail-off after first 6-10 channels In both cases, the top channel accounts for more viewing than all channels outside top 6 DTT is inefficient medium for distribution of very small channels Online TV / broadband can help: but mobile needs spectrum UK FRA These two graphs show channel viewer share – by percentage – in UK and France as their DTT markets began to mature in We will see similar maturity in Africa soon. The figures show that, after the first 6 to 10 channels, much lower viewing figures occur. These tail off to tiny figures for the last 15 or so. However, these last 15 channels will make the same use of the airwaves – will have the same spectrum demand – as all the others. Because of this, tiny channels have a very high transmission cost per viewer compared to the bigger ones when broadcast over DTT. Transmitting these niche channels online would greatly improve the efficiency of spectrum usage. Mobile can provide greater efficiency, but we need spectrum. Source: Human Capital, 2008

Africa: Covering All Areas
Africa’s huge landmass creates specific difficulties for network operators Ensuring all consumers have the benefits of mobile broadband has a strong demand on spectrum and there are two vital bands for the LTE community: 2.5GHz Digital Dividend band Coverage of rural areas needs lower frequency spectrum to reach further Digital divide between urban and rural areas will be lowered by the Digital Dividend In to provide deliver broadband – and broadband video – to the African continent, the Digital Dividend is vital. The vast size of the African continent provides a unique challenge in providing comprehensive mobile coverage. Significant landmass is coupled with large numbers of rural population. This challenge is increased due to the lack of fixed line infrastructure: mobile voice massively outweighs fixed, while mobile broadband has overtaken fixed broadband in most countries, putting intense pressure on spectrum allocations. The African need for frequency spectrum for broadband is thus as strong as anywhere else in the world.

Since October 2007 ITU regions have been engaged in meetings to agree on channelization arrangements The main aim is harmonization , for the obvious reasons of economies of scale.

Thus the so called “dividend” in the MHz is effectively reduced by 38MHz ( illustrative, bear in mind the centre gap) Causes a bit of a challenge , Europe rapidly moving towards agreed harmonized channeling plan.

Conclusions Assess the REAL need of Digital TV and the most spectrum-efficient means of distributing Assign DTT frequencies from the lower part of the band: even if re-planning is needed Ensure that regional discussion takes place and bear in mind opportunities for harmonization with other regions Old broadcast models are changing: mobile broadband can help the broadcast community reach more people more efficiently Please contact for more information How much digital content is there? What have other regions done? 698 MHz seems to be a natural choice for harmonization with region 2 and parts of region 3 2012/13 should see maturing of LTE, thus give additional insight to inform choices. These considerations must be done as a region/sub regions; excellent frameworks exist; SADC; WATRA; EAC etc. GSMA and its members are ready to support the broadcast community in delivering more content to more people.
