What is 4G LTE?
4G LTE is a wireless mobile communications technology sometimes
referred to simply as ‘4G’ – it’s the natural successor to ‘3G’ mobile networks, allowing
mobile phones to access the internet at speeds similar to many home broadband connections. It’s also known by some as
3GPP Long Term Evolution.
How fast is 4G LTE?
It should be fast enough to stream internet videos without
having to suffer buffering and potentially allow you to download HD videos in a matter of minutes. EE, the first 4G network
in the UK, claims its 4G network is five times faster than 3G networks.
The theoretical peak download speeds for 4G LTE are 20Mb/s, but in reality speeds
will be lower – real-world speeds for 4G LTE networks in the United States vary between 8 Mbits/s and 12 Mbits/s.
Some versions of 3G, such as HSPA+,
can offer similar speeds. Where 4G LTE has an advantage is in ‘latency’ – the time delay in responding to
actions. 4G LTE’s superior latency means it’s more responsive, which improves the overall experience.
Where can I get 4G LTE?
EE is the first network to launch a
4G service in the UK and began to roll out the service in September 2012. This is from the company that owns Orange and T-Mobile
and it claims that users of these networks will be able to easily upgrade to the new 4G service.
Initially the service will only be available in major cities,
but EE claims it will be available to 70% of the population by the end of 2013 and 98% of the population by the end of 2014.
Other mobile networks will be launching
4G services at the start of 2013.
How much will it cost?
So far EE hasn't released any pricing information for its 4G network, although we would expect it to be more expensive
than 3G contracts.
I need a new phone?
access the new network you will need a 4G-enabled phone. EE will be launching 4G handsets from Apple, HTC, Huawei, Nokia and
Samsung. It is also offering 4G dongles and personal hotspot products.
The third-generation iPad was previously sold in a ‘Wi-Fi + 4G’ version,
but it will not work on UK 4G LTE networks when they become available and Apple has been forced to change the name to 'Wi-Fi
the iPad with Wi-Fi & 4G work 4G LTE in the UK?
While the iPad does support 4G in the United States and Canada, the UK and Europe are using different ‘frequencies’
for 4G LTE. The iPad supports 700MHz and 2,100MHz frequencies, while the UK will predominately use the 800MHz, 1,800MHz and
2,600MHz frequencies to deliver 4G LTE.
Are there any disadvantages of 4G?
Aside from the extra cost of getting a 4G service, there is a suggestion that 4G may use up more power and drain
batteries faster than accessing the internet on a 3G handset. We will be taking a close look at this in our lab tests once
the phones go on sale.
Mr 4G - Advantages
bandwidth *Better repsonstime. 10 times better then 3G *Works at 2.6GHz frequency wich means better coverage even
though it uses the same tower where the receiver and transmitter for 3G is. *Less time to buid 4G because it use the
same tower and fibercables as 3Gs - they only have to upgrade the towers with 4G components.
* New technology wich makes it
more expansive than 3G
