NSN unveils new TDD-LTE 8-pipe radio module for Band 41 spectrum

Operators will now be able to use Band 41 (2.4-2.6GHz) spectrum band for TDD-LTE services, helping them to meet the demand for mobile broadband

NSN unveils new TDD-LTE 8-pipe radio module for Band 41 spectrum

Nokia Solutions and Networks (NSN) has launched a new TDD-LTE 8-pipe radio module for Band 41 spectrum (2496MHz to 2690MHz). The new base station component will enable operators to use the 2.6GHz TDD-LTE (time division duplex LTE) spectrum band to meet booming demand for mobile broadband.

NSN claims that it is the industry’s highest capacity 8-pipe radio module, as it supports up to 120 MHz of channel bandwidth. It delivers twice as much transmission power output than previous versions, substantially improving the user experience, particularly at the edge of a cell’s coverage.

NSN’s new base station radio module will help satisfy growing demand for high-quality mobile broadband and voice services, which is now a deciding factor in choice of operator.

It extends NSN’s Flexi Multiradio 10 base station family with an 8-pipe radio module that supports the growing number of countries adopting the 2.6GHz TDD-LTE spectrum, including Brazil, China, India, Japan, Russia and the USA.

The radio module is fully future-proof, ready for the evolution of carrier aggregation and capable of supporting an unprecedented 120 MHz of bandwidth that can deliver more than 1.2 Gbps of total site throughput from a single unit.

“For subscribers, quality means everything. With our high-capacity base stations, mobile subscribers will have the outstanding service experience they are looking for,” said Marc Rouanne, executive vice president, mobile broadband, at NSN. “We are introducing the industry’s most powerful TDD-LTE 8-pipe radio module with support of 120 MHz bandwidth and 160 Watts transmission power.

“As the new NSN radio module is capable of supporting LTE-Advanced technology with the possibility to aggregate up to three carriers, three-fold peak cell data rates can be achieved compared to the performance of the currently deployed commercial networks. This enables the world’s leading operators to provide unrivalled data speeds to their customers and also showcases NSN’s global leadership in the LTE domain, as proven by the first deployments of carrier aggregation in South Korea last summer,” said Rouanne.

The TDD-LTE 8-pipe radio module supports three sectors in a single unit even for remote configurations, unlike conventional remote radio modules that run only one sector per module. It needs no air conditioning and can be pole-mounted or placed near the antenna tower base, substantially reducing installation and maintenance costs.

As a concrete proof point, the US operator Sprint, which has recently selected NSN as its partner to roll out a nationwide TDD-LTE network, will be using NSN’s new high-bandwidth 8-pipe radio module for its TDD-LTE deployment in Band 41 spectrum range.

NSN has a series of TDD-LTE speed records under its belt including a demonstration of world record throughput speeds of 1.6 Gbps where data was sent and received in simultaneous downlink and uplink connections.

To enable seamless use of both FDD-LTE (frequency division duplex LTE) and TDD-LTE services, NSN also demonstrated the world’s first data traffic offloading and load balancing between TDD-LTE and FDD-LTE using its Single RAN Advanced Flexi Multiradio 10 base station.

Nearly all smartphone manufacturers have announced support for dual-mode smartphones, enabling operators to deploy TDD-LTE as an integral part of their overall mobile broadband service.
