Kawan2 Anggota Milis Yth,
International Telecomunaction Union (ITU) akhirnya menyerah bahwa walaupun
pihaknya tetap pada pendiriannya tentang Definisi 4G rigid yang menurutnya
hanya berlaku bagi WiMAX 16m dan LTE Advanced, namun secara realistis istilah
4G dapat dipakai bagi teknologi awal WiMAx dan LTE, yaitu WiMAX 16e dan LTE
biasa.
Ini sebuah pengakuan yang jujur, sebab kedua teknologi awal 4G itu (WiMAX 16e
dan LTE) memang merupakan loncatan teknologi baru yang berbeda dari teknologi
3G yang di-disain utamanya untuk layana Voice, SMS dan Fax, sedangkan untuk
layanan Data, merupakan teknolgi tambahan atau "add-on" saja.
Berikut ini adalah pengakuan jujur dari ITU itu sbb:
ITU capitulates, admits that the term '4G' could apply to LTE, WiMAX, and
'evolved 3G technologies'

Though
it's standing firm on the definition of its original 4G specification --
IMT-Advanced -- which only WiMAX 2 and LTE-Advanced are currently capable of
meeting, the ITU is easing off its earlier rhetroic, admitting that the term
"4G" realistically could apply "to the forerunners of these technologies, LTE
and WiMAX, and to other evolved 3G technologies providing a substantial level
of improvement in performance and capabilities with respect to the initial
third generation systems now deployed." The whole dust-up started when
carriers around the world deploying LTE and WiMAX networks (ahem, Sprint and
Verizon) were throwing the "4G" term around very, very loosely -- and to their
credit, the networks are indisputably a generation beyond CDMA2000 and UMTS /
HSPA, so if anything, we'd fault the ITU for leaving today's modern networks
without a generation to call their own. The "evolved 3G technologies" verbiage
in the ITU's statement would seemingly even leave room for T-Mobile USA's
claim that its 21Mbps HSPA+ network constitutes 4G... so yeah, score one for
marketing campaigns. Of course, none of these carriers had ever planned to bow
to the ITU's recommendations anyway, so the ruling has little practical
relevance -- just know that the true 4G speeds are still a few years off.
Silahkan ditanggapi demi kemajuan bangsa dan negara.
