LTE vision becomes reality
As commercial rollouts begin, Long Term Evolution (LTE) is becoming a reality, with the next-generation mobile technology poised to outdo its rivals as the natural migration choice for operators.
July 20, 2009
Mobile broadband is gaining momentum and shaping the way people communicate. And mobile networks are leading the way, not any of the alternative wireless technologies that have been hyped over recent years, says Ulf Ewaldsson, vice president and head of Product Area Radio at Ericsson.
This trend was evident at this year’s LTE World Summit held in Berlin in May, at which it was heard that while GSM and HSPA will be around for some time, and while the time frame differs, full LTE commercialization is certain.
More than 30 major operators in more than 16 countries are already committed to deploying LTE in the coming years.
“A smaller, second wave of operators are now starting to plan for LTE. This shows that the vision of LTE is coming down to earth and is here to stay,” Ewaldsson says.
“By 2014, we expect that around two-thirds of the world’s three billion broadband subscriptions will be mobile with more than 80 percent based on HSPA and LTE. The speed of adoption is directly connected to the fact that global standards such as LTE offer a superior user experience with high speeds and great capacity, while simplifying technology for next-generation mobile broadband.”
LTE enables unprecedented performance in terms of peak data rates, spectrum efficiency and delay.
“Ericsson has already demonstrated peak rates of 160 Mbps. LTE can be deployed both on new and existing frequency bands and is designed to minimize the cost of network operation and maintenance. LTE outpaces all other technologies in meeting key 4G requirements,” Ewaldsson says.
“LTE offers operators flexibility and simplicity,” he adds. “It is designed for broader bandwidth than HSPA and GSM, and it can be deployed on whatever spectrum is available.”
Today, operators can introduce LTE to match their existing networks, spectrum and business objectives for mobile broadband and multimedia services. This enables a fast and seamless rollout.
Ewaldsson says that because it belongs to the world’s most widespread family of standards – the 3GPP GSM/WCDMA/HSPA standards – LTE involves most cost-efficient transformation for most networks. LTE is designed to smoothly interwork with many existing radio technologies (GSM/WCDMA/HSPA, TD-SCDMA and CDMA), making it the perfect next step in mobile broadband.
“Many operators are talking about LTE as the natural evolution path for today’s GSM/HSPA and CDMA systems with the argument that LTE is more cost effective,” Ewaldsson says.
