PremiumVIVAnews -Government requested immediate drawing up regulations relating to the development of 4 g LTE infrastructure instrument (long-term evolution). The reason, the current operator is ready and Central Government decision menunggu-nunggu to roll out LTE 4 g services.
Because there is no certainty when 4 g LTE is applied, the operator has not been able to take steps to develop the service.
"If frequency, we are also hard-pressed to choose will use technologies like what," said Dian Siswarini, Director of Network and Services PT XL Axiata, on tree planting program the Green Back on the slopes of Merapi Volcano, Glagaharjo Village, Cangkringan, Sleman, Yogyakarta.

This technology, said Dian, is very important given the current voice services has experienced a downturn. "So, the next three years we've not yet talk voice services," he said.
XL themselves have already done a test LTE in December 2010.
Currently, according to Dian, a comparison of voice and data services in the 2 g is already about 50: 50. "If the 3 g, almost 90 percent of use already use data services," said Dian.
Dian mention, actually currently there are several candidates the frequency that can be allocated to LTE, including 1.8 GHz, 900 MHz, and 700MHz. "the frequency of 1 GHz is possible if refarming do 2 g and 3 g technology. It's just that, spend the investments out will be much greater, "he said.
With regard to the frequency 700MHz is still occupied by a number of the Organizer broadcast television free to air national, which the new NET frequency on 2018 after all national TV migrates to digital TV channels.
