freund von harry potter 3 buchstaben check The limited wireless spectrum that has been released for commercial use in South Africa is a thorn in the side of industry players, because more is badly needed to ease network bottlenecks and support new services. “The delays in the allocation of the available wireless spectrum in South Africa is embarrassing when other African countries have forged ahead with this,” says Ian Isenberg, business development manager at Internet Solutions.

Dawie de Wet, CEO of Q-Kon says the allocation of wireless spectrum can help to relieve the current bottlenecks on the existing last mile infrastructure that links customers to their ISPs.

This will free up spectrum, especially on the 700 megahertz frequency, which provides a good balance between distance and speed.

zee mermin pakte koop “For Africa, we need long distance reach and reasonable speeds up to 10 megabits per second and the 700 spectrum provides that.” Martin Ferreira, executive head of technical operations at Jasco ICT Solutions says it seems that only four wireless spectrum licenses will be allocated for use of the 2.6 gigahertz spectrum, which supports broadband services such as the next generation Long Term Evolution (LTE) mobile technology.

However many of them will baulk at paying a licence fee for this spectrum when they can continue to use the unlicensed frequencies for nothing, and few will be able to afford it anyway. “This is why there are so many wireless service providers using the unlicensed frequencies,” says Carlsen.

He says the unlicensed spectrum frequencies are overcrowded in urban areas, but not in rural areas.  While fibre infrastructure is available across the country from large operators, a smaller service provider would need to have 1000 customers to justify the cost of connecting to it, says Carlsen.

“We have to buy a chunk of capacity.” He says it is cheaper to use a satellite broadband service.

It takes huge money to launch and operate a satellite, but the service is costed on a longer term basis. “The satellite owners are not out to make profits from day one,” says Carlsen.
