StarHub's SmartPTT Push-to-talk over Cellular (PTToC) Solution

Back in November, the Singaporean MNO StarHub announced the launch of Singapore’s first 5G-capable mission critical communications solution, enabling enterprises and government agencies to communicate with specified groups of people simply by pressing a Push-to-Talk (PTT) button. 

A press release said:

Named StarHub SmartPTT, the new solution sets up an encrypted enterprise-grade network over StarHub 5G and 4G connectivity, for identified mobile phones to function just like walkie-talkies or two-way radios – boosted with crystal-clear quality, unlimited range nationwide, and first-of-its-kind ‘live’ video feeds.

StarHub SmartPTT is a one-stop solution comprising island wide 5G/4G connectivity, ruggedised PTT devices, customisable user application, training, and comprehensive after-sales support with guaranteed response times. Customers just need to liaise with a single party for all of their instant and critical communication needs.

In addition, the solution offers a dispatch console for organisations to integrate voice, video, instant messaging, and CCTV feeds. Through this unified web interface, dispatchers can in real-time manage PTT groups and services, listen in to conversations, monitor video feeds, define geo-fencing limits and alarms, and activate voice recording.

With assured Quality of Service on StarHub SmartPTT, all PTT calls will always be given dedicated bandwidth and treated as top priority traffic. Even if there is network congestion, users will be able to talk, share videos, and text one another with no impact to service.

Starting today, customers can pair StarHub SmartPTT with the RugGear RG360 phone, which comes with a large dedicated PTT button, noise-cancelling dual microphones, and powerful front-facing speaker. Featuring 18 hours of battery life, this Android phone has the highest dust- and water-proof rating of IP68 and is MIL-STD-810H certified. Ruggedised 5G phones models are expected to reach Singapore shores next year.

StarHub SmartPTT is suitable for use across various industries, including public safety, aviation, construction, healthcare, hospitality, manufacturing, and transportation, among others.

Highlights from XGMF's Conference to Advance Millimetre Wave Technology

On April 1, 2024, two of Japan's leading connectivity organizations—the 5G Mobile Promotion Forum (5GMF) and the Beyond 5G Promotion Consortium (B5GPC)—joined forces to create the XG Mobile Promotion Forum ( XGMF ). This merger symbolizes a pivotal step in accelerating the adoption of next-generation wireless technologies. In May 2024, XGMF's Millimeter Wave Promotion Ad Hoc (Millimeter Wave AH) hosted the International Workshop on Millimeter Wave Dissemination for 5G. This event aimed to foster the adoption of millimeter wave (mmWave) technology in Japan and beyond, drawing an audience of approximately 200 attendees and broadcasting in both English and Japanese. The workshop featured opening remarks by Mr. Naohiko Ogiwara, Director of the Radio Department, Telecommunications Infrastructure Bureau, Ministry of Internal Affairs and Communications (MIC). Key speakers included: Mr. Takanori Mashiko (MIC, slides ) Mr. Sam Gielges (Qualcomm, online - no slides) Mr. Christopher Pric...

Testing, Refining, and Improving Stratospheric Connectivity: NTT Docomo’s HAPS Trials

At MWC 2025, NTT Docomo highlighted its latest initiatives under the NTT Group's "NTT C89" space-business strategy, such as mobile-connectivity services using unmanned vehicles, or high-altitude platform stations (HAPS), that fly in the stratosphere for days or months, using relays to provide mobile connectivity in mountainous and remote areas, including at sea and in the sky. A presentation on NTT C89 Aerospace Business Strategy is available here while a presentation on NTT DOCOMO's Non-Terrestrial Network (NTN) for Extreme Coverage Extension is available here . Stratospheric connectivity, enabled by High Altitude Platform Stations (HAPS), is emerging as a key solution for extending mobile coverage to remote and underserved areas. However, ensuring that these airborne platforms can provide stable, high-quality connectivity requires extensive testing and refinement. At MWC 2025, NTT Docomo showcased its progress in this domain, highlighting multiple real-world trials...

How Do Apple AirTags Work?

Apple AirTags have steadily gained popularity in the smart tag market. A recent report highlighted that 69% of smart tag buyers in late 2024 chose an Apple AirTag. This marks a significant rise from 45% in early 2022. In contrast, Tile, the category pioneer now owned by Life360, has seen its market share fall to 11% from 17% during the same period. Samsung's Galaxy SmartTags now hold second place. Interestingly, the technology behind AirTags resembles concepts like Opportunity Driven Multiple Access (ODMA) or Multihop Cellular Networks (MCNs), which I have previously explored . A similar approach has also been discussed regarding Bluetooth-based Ad-Hoc networks . How Do They Work? AirTags primarily use Bluetooth Low Energy (BLE) to communicate with nearby Apple devices that are part of the Find My network. This vast network consists of millions of Apple devices, including iPhones, iPads, and Macs, which can detect AirTags and securely relay their location back to the owner. Addit...
