Definition of 4G in English:



  • A mobile communications standard intended to replace 3G, allowing wireless Internet access at a much higher speed.

    ‘they recently announced that the newest iPad will support 4G’
    [as modifier] ‘when a 4G phone can't find a 4G network, it falls back on 3G’
    • ‘4G infrastructure sales should reach $5.3 billion annually in 2007.’
    • ‘For wide-area high-speed wireless data, 4G may be better as it does not concern itself with the circuit-switched legacy that 2.5G and 3G systems conform to.’
    • ‘And forget about putting a 4G phone in your pocket.’
    • ‘Other attributes for 4G include less reliance on infrastructure (fewer base stations per pop), greater spectral efficiency, and superior economics compared to 3G.’
    • ‘When we get to 4G, we'll also want things like multi-user detection.’
    • ‘While many Irish people are busy getting to grips with 3G technology, the institute will be developing 4G phones, which will be able to adapt to any standard or band throughout the world.’
    • ‘In the interim, both Wi-Fi and 4G are gaining momentum.’
    • ‘As today's wireless market progresses and we head toward 2.5G, 3G, and even 4G mobile phones, reconfiguring computer chips on the fly becomes a key factor in the viability of sophisticated mobile services.’
    • ‘True wireless broadband data access is likely to have to wait until 4G systems arrive, at which time the potential for increased voice usage is likely to be exhausted.’
    • ‘4G is close on the heels of 3G, with "forward-thinking wireless operators who are now working … to leapfrog expensive and ineffective third generation wireless strategies".’
    • ‘4G is the emerging wireless telecommunications technology that will support voice and data transmissions at the same rate as wired Local Area Networks (100 Mbps).’
    • ‘Interest in solutions that are being coined 4G will continue because they offer operators something that 3G has failed to deliver in Europe, an attractive business model.’
    • ‘Not only will it be harder, if 4G standards are dominated by a different set of interests and technologies, to gain return on their huge investments in 3G, but they will not be able to exploit those technologies in moving to the next generation.’
    • ‘Though years away, Intel is already putting thought into what may feature in 4G telecommunications devices.’
    • ‘After 10 years, we'll then begin shifting to 4G.’
