AT&T struggles to defend open cloudiness of Ericsson deal
More than a year into the Ericsson-led rollout, there is very little evidence AT&T's radio access network is as multivendor and virtualized as the telco makes out.
Indosat Ooredoo Hutchison has deployed more than 550 ultra-capacity microwave backbone links across Indonesia to expand its 4G coverage.
Indosat Ooredoo Hutchison (IOH) has deployed over 550 ultra-capacity microwave backbone links across Indonesia to expand the coverage of its 4G services to remote and rural areas of the 17,000-island archipelago.
In an announcement on Friday, IOH said the initiative has significantly increased Indosat's subscriber base, particularly in remote areas, where backhaul capacity in regions such as Sumatra and Kalimantan has increased to 2-3 Gbit/s, with peaks of 6 Gbit/s.
"Residents now enjoy uninterrupted access to real-time information, online education, and digital entertainment. The enhanced connectivity has also catalyzed local economic growth by creating jobs, boosting tourism, and fostering knowledge sharing, all while supporting advancements in healthcare and education," the telco operator said.
Tackling Indonesia's geographic challenges
IOH noted that traditional wired communications struggle with the country's rugged terrain and high costs, leaving many areas digitally disconnected. This lack of access hinders economic opportunities and limits social development, highlighting the urgent need for cost-effective and accessible solutions.
The telco operator teamed up with ZTE, which provided its microwave technology, to cover nearly 80% of Indonesia's major cities and remote islands.
The microwave solution uses multi-frequency, ultra-broadband antennas that allow frequency selection, which ZTE said reduces tower load and rental costs. It added that the solution's customized branching units minimize hardware requirements, which improves cost efficiency while maintaining high performance.
In addition, the solution design integrates 4T4R modem boards for rapid deployment and supports smoother upgrades, enabling IOH to increase capacity up to eight times and extend coverage to new areas, according to ZTE.
"At Indosat, we are committed to empowering Indonesia by bridging the digital divide," Desmond Cheung, IOH director and chief technology officer, said in a statement. "By deploying advanced technology, we are not only improving digital experience but also unlocking opportunities for economic and social progress, creating a brighter digital future for Indonesia."
