Optus Revolutionises DSS by Running Narrow-Band IoT, 4G and 5G

Optus on Friday made use of Dynamic Spectrum Sharing or DSS in order to run narrow-band IoT, 5G and 4G mobile on its existing 700 MHz spectrum, a move, that, as per the company, will allow for the boosting of its 5G coverage. This was made possible via Ericsson’s spectrum sharing kit.

The two firms, who have been partners for the past couple of years and have worked on DSS in order to share frequency resources between 4G and 5G, described this latest trial as a world first, which also brings NB-IoT into play.

The telco has not yet provided any information regarding a commercial launch, but, going from the company, a full-scale and rapid rollout does not seem to be possible.

Do note that Optus is still keen on working, adding that the implementation of this tech will allow for broadening of the 5G footprint, with the use of the technology helping in unlocking a cost-effective method of offering 5G services via low spectrum bands, not conflicting with the user experience in mid-band 5G services.

Lambo Kanagaratnam, the Managing Director of Optus Networks mentioned that this test has shown that Optus’ 5G coverage footprint on its world-class network can be extended without compromising 4G and NB-IoT customer experience and marks the first step into being able to carefully introduce this technology.

What Else Do The Tests Indicate

The test also highlights the ability to achieve spectrum efficiency via enabling multiple services and technologies on the same spectrum resource, he added.
