What is data speed?
Data speed is the rate at which media is transferred from one device to another. The transfer rate is measured in multiples of bits: the basic unit of measurement in computing and digital communications. The increments are kilobits per second, megabits per second, gigabits per second and terabits per second.
Although data speed is dictated by technological capabilities, things like the optimal transfer rates and technology used, etc are regulated.
a company that specialises in worldwide mapping mobile coverage and performance, in its third quarter of 2015 report. Last year the Singapore-based telecommunications operator Starhub recorded the highest 4G LTE download speed at 38 Mbps.
Mobile data speed in South Africa
By the third quarter of 2015 local mobile communication companies ranked below the global average, reports Opensignal. Vodacom's LTE speed ranked 144th globally, with an average download speed of 10 Mbps; MTN ranked at 173rd, with an average 4 Mbps download speed.
It's worth noting that poor data speed is not only the fault of network providers. For network providers to increase data speed, they need access to increased broadband spectrum. Spectrum is a range of electromagnetic frequencies that wireless devices use to transfer data, and this is regulated by Icasa, the Independent Communications Authority of South Africa. Icasa hopes to auction spectrum to network providers to ensure fair competition, Independent Online reported in February.
Near-field communication, commonly known as NFC, is used for short-distance data relay. It enables portable devices such as smartphones to communicate at a distance of up to 4 centimetres. NFC data speeds range between 106 and 424 Kbps.
Although NFC technology has not become popular in SA, in some countries banks have adopted it as a method for mobile transactions.
Bluetooth Core Specification, or simply Bluetooth, is the smartphone connection technology of choice for hands-free communi- cation in vehicles and wireless connectivity between computers and peripherals. It allows communication between devices up to 10 metres apart. Latest-generation Bluetooth 4.0-capable devices can transfer data at up to 24 Mbps.
Developed as a method for devices to communicate without the use of a wireless access point such as a router, Wi-fi Direct allows for data transfer at speeds of up to 250 Mbps. The technology was first adopted by Intel in 2008, and has steadily grown in popularity in recent years. Ease of user can set it up.
At the moment a limited range of mobile devices and peripherals come with Wi-fi Direct as a feature, but the mobile industry firmly believes its popularity will grow.
4G now, 5G soon?
Not quite. Globally countries are still actively adopting 4G and LTE, and increasing existing coverage of these technologies. And although much of the world is abuzz with the potential 5G could have on connectivity between devices and even vehicles, the reality is that the technology is at least four years away. The ITU-R recently published a timeline outlining the steps towards the 5G standard, with 2020 being the estimated year for the rollout of next-generation specifications.
To make Mowgli's riding motions look realistic, visual-effects supervisor Rob Legato invented a rig that could simulate the muscle movements of actual animals. Legacy Effects, which created hydraulics for Jurassic Park, built the machine, and the staff nicknamed it the Faverator. “The computer animators mimic the way the animals move,” Legato says. “Then you program that to the rig and the computer figures out what the pistons have to do to create the same motion.” The idea came from pinart toys – on which a kid can place his hand under nails to make shapes – which is definitely the first time those have ever been useful.
