Life at the ‘4’front

Fast mobile data transfers will take a while
In a scenario where ‘staying connected’ seems to be the inherent mantra of the organizations and people worldwide, the technological advancements in the mobile broadband arena are being watched closely by the tech experts. Recently, Nokia Siemens Networks (NSNs) completed the multi-user field trial using the new Long term Evolution technology (LTE).

Noticeably, this was the world’s first filed trial in an urban environment, which offered mobile data rates of up to 173 Megabytes per second. Interestingly, before this, such high speed mobile data transfers were absolutely unheard of, considering the fact that the traditional mobile broadband offers an infinitesimal speed of 7.2 Mbps and the promising mobile Wimax can only stretch up to a speed of 70 Mbps.

Such trial is important considering the fact that the use of mobile multimedia services over the internet is on the rise and requires quicker response time and faster data transfer rates. ”As the world continues to move closer to our vision of 5 billion people connected by 2015, mobile operators will need to use all of the available spectrum with minimum network complexity and maximum cost efficiency,” says Stephan Scholz, CTO of NSNs. “This field trial is an important initial proof of concept for LTE,” he further adds.

Interestingly, the fact that NSNs achieved the highest mobile data transfer rates of 173 Mbps over several hundred meters point towards the high efficiency levels of LTE technology as compared to that of WiMAX. If deployed on a large scale, LTE can help the mobile broadband companies in connecting maximum number of people using the minimum spectrum. “We can demonstrate that LTE meets the high expectations set for this new technology,” adds Matthias Reiss, who is the head of LTE Radio at NSN, further emphasizing on the evidence (extracted out of this trial) that future LTE networks can run on existing base station sites and mobile operators can build LTE networks without requiring new antenna sites.

Interestingly, LTE, which is a modulation technique designed for GSM based technology – seems to be a bit of a late entrant when clubbed with mobile WiMax, another wireless technology, which is now already in practice in certain pockets of UK. However, these are just packets of individual technologies that find themselves in a race to proclaiming the 4G crown. The crown, in contrast, lies way beyond for now.
