Engr. Timasaniyu Ahmed-Rufai, chief executive officer, Nigerian Communications Satellite Limited (NigComSat) has x-rayed how broadband could improve economics and create a win-win situation for governments and concluded that his agency has the ingredients to add pep to the broadband revolution.
Speaking at the 2013 e-Nigeria conference on local content hosted by Nigerian IT Development Agency (NITDA) recently in Abuja, Ahmed-Rufai asked in his paper “Satellite based broadband in Nigeria, prospects and challenges” Why Broadband? and listed the seemingly misgivings and skepticism of policy makers that broadband can actually deliver services and improve the wellbeing of citizens?
He provided some answers in his paper, listing various aspects of broadband delivery, which include Asymmetric Digital Subscriber Line (ADSL), Digital Subscriber Line (DSL), Cable broadband, Wireless broadband like GSM, WIMAX, CDMA and Wi-Fi, Symmetric broadband (SDSL) and Satellite broadband via Communications Satellite on varying bands including Ku, C and most recently higher spectral frequencies like Ka-band and beyond.
According to the NigComSat boss, Africa remains the least wired continent in the world today “in terms of robust telecommunications infrastructure and systems to cater for its nearly one billion population”.
This underscores the reason for high demand in the form of communication satellites and variants of terrestrial wireless systems more than in any other continent for the sole purpose of bridging its digital hiatus, complementing the group of inadequate terrestrial ICT infrastructure in the rural areas, swampy and landlocked terrains thus playing a critical role of delivering ICT readiness in un-served and underserved areas.
In Nigeria for instance there is a combined landed submarine optic fibre capacity of over 10 terra bit per second (Tbit) but only about 0.5Tbps gets to the hinterland.
Besides: Internet penetration stands at 33% while broadband penetration is put at 6%; 72.25% of access is via wireless networks, mainly GSM while the remaining 27.75% access is via other media; and 2G mobile coverage is 65% while 3G is only 35% and this is concentrated in urban areas so technically only urban areas enjoy the luxury of broadband.
And in a country where over 70% of its population resides in the rural areas, he said the limitation of access to broadband via cable may be bridged via NigComSat-1R which could serve as conduit to improve access links but sadly NigComSat-1R is today grossly underutilised.
The effect is that huge capacity of cable broadband is left at the shores thereby encouraging capital flight which is put at $450m yearly spent on bandwidth purchase from abroad.
Ahmed-Rufai emphasized that Communications Satellite is the answer as a “low hanging fruit” to meet short and medium term plans of the National Broadband Plan, because “if we must optimize access to information and guarantee universal access in the short and medium term to all citizens, including those in the remote areas then communication satellite should remain within the framework of our ICT policy and broadband implementation to complement existing but inadequate terrestrial infrastructure as well as strategic national and continental telecommunication infrastructure during natural disasters and emergencies.”
He also advised that there should be a policy by government on the use of satellite broadband as primary source of internet in rural and swampy areas with associated ground technologies and redundancy in areas with optic fibre to mitigate against cuts, damages and theft considering our geography, lack of channelized roads, subways, railways and poor urban and regional planning.
Ahmed-Rufai said Satellite Communications can indeed deliver broadband because it has been a major means of broadcast, mass media, free to air TV, medical science especially Tele-medicine, e-learning among others.
NigComSat-1R was launched December 19, 2011, and it is a quad band made up of C, K, Ka, and L bands. There are 40 transponders out of which 28 are active while 12 are redundant. Commercial activities on the satellite began on March 19, 2012 after a successful In-Orbit Test (IOT) and In-Orbit Delivery (IOD) with modest achievement in terms of improving and driving national broadband access in homes, offices, businesses, schools in Nigeria as well as prospects and potentials outside Nigeria.
