Telecom Lead Asia: Nokia Siemens Networks is
extending its TD-LTE technology to support the 1.9GHz frequency
bands. It will allow operators to use existing 1.9GHz spectrum allocations to
provide TD-LTE services.
The expansion of our TD-LTE portfolio to the 1.9GHz
bands marks another step forward in Nokia Siemens Networks’ commitment to driving
the TD-LTE ecosystem by supporting China Mobile’s strategy, and at the same
time accelerating TD-LTE deployments globally,” said Markus Borchert, president
at Nokia Siemens Networks Greater China.
TD-LTE provides a much faster and highly responsive mobile
internet experience, offering speeds of up to 112 megabits per second (Mbps).
All these TD-LTE benefits will now be available in the 1.9GHz bands, extending
the reach of TD-LTE.
The expanded TD-LTE capability was first introduced at a
customer event organized by Nokia Siemens Networks for China Mobile.
However, China Mobile is planning to evolve its TD-SCDMA
network to dual-mode, supporting both TD-SCDMA and TD-LTE services in the
1.9GHz band via a simple software upgrade.
The TD-SCDMA spectrum can then be reframed to support
TD-LTE services, hastening China Mobile’s move to the 4G technology.
As part of Nokia Siemens Networks’ TD-LTE evolution, the company’s Flexi
Multiradio 10 Base Station now supports 1.9GHz TD-LTE.
Nokia Siemens Networks will be conducting lab trials of
its TD-LTE capability in the 1.9GHz band at its Hangzhou open lab in China, and
this offering is expected to be commercially available by Q4 2012.
MWC: Nokia Siemens Networks breaks 4G speed record with 1.4
Gigabits-per-second mobile call
At the Mobile World Congress, Nokia Siemens Networks
demonstrated its Flexi Multiradio 10 Base Station that boosts data rate for
LTE-Advanced on 100 MHz spectrum.
Earlier in February, NSN achieved world record
data speeds exceeding 1.4 Gbps using an LTE-Advanced (4G) system on 100 MHz of
aggregated spectrum. The feat was repeated at MWC. The calls, involving huge
file transfers and HD video streaming, hit peaks of 1.429
Gigabits-per-second.
