NSN, Optus build world’s first ‘Gigasite’, achieving 1.7 Gbps downlink in a live network

“With this world first ‘Gigasite’, we are showing the capacity of all our spectrum assets, including our recently purchased 700, 2300 and 2600 MHz bands, by combining multiple layers and technologies onto a single site. Trials such as this are vital in enabling Optus to prepare for our network of the future, and support more users and more data per user while at the same time enhancing the customer experience,” said Andrew Smith, Vice-President of Mobile Engineering, Optus.

“The beauty of this trial with Optus is that it uses equipment and technologies already deployed in today’s commercial networks,” said Stephen McFeeley, head of Australia and New Zealand at NSN. “This is an important step because we foresee that networks will need to be readied to profitably deliver 1 Gigabyte of data per user per day on average by 2020.”

Using NSN’s commercially available Single RAN Advanced*** which is based on its compact, energy-efficient Flexi Multiradio 10 Base Station, Optus took advantage of six of its existing 3GPP spectrum allocations to build a live network site at St Mary’s in western Sydney. The aim was to demonstrate the technology needed to meet burgeoning mobile broadband demand.

The site was built using HSPA+, FDD LTE and TD-LTE technologies in a lean site solution implemented with the award-winning Flexi Multiradio 10 Base Station. The NSN Flexi Multiradio 10 Base Station is the industry’s highest capacity base station.

Notes:
* The 1.7 Gbps represents the total site downlink measured as the combined speeds achieved on each spectrum layer. The figure was achieved using a total of 226.8 MHz spectrum.

** The Optus trial is a field site based on the following frequency bands and technologies:

a. FDD LTE: 700 MHz (2 x 10 MHz, 3GPP Band 28)
b. HSPA+: 900 MHz (2 x 5 MHz, 3GPP Band 8)
c. FDD LTE: 1800 MHz (2 x 15 MHz, 3GPP Band 3)
d. HSPA+: 2100 MHz (2 x 20 MHz, 3GPP Band 1)
e. TD-LTE: 2300 MHz (80 MHz, 3GPP Band 40)
f. FDD LTE: 2600 MHz (2 x 20 MHz, 3GPP Band 7)
