Canadian provincial operator SaskTel has unveiled a new push-to-talk-over-cellular (PoC) service running on 3G/4G networks, aimed at business users, which will eventually replace the existing ’10-4’ PoC service operating on its CDMA network. The Regina Leader-Post reports that SaskTel’s new PoC service will be available across its HSPA-based network covering approximately 98% of the population of Saskatchewan province. The service is based on Kodiak Network’s InstaPoC technology platform, offering enhanced capabilities compared to 10-4, SaskTel announced. For instance the older system has a limit of 200 mobile devices in a PoC work group, whereas the new generation version allows users to communicate with up to 1,000 individuals within a group and also create groups that can be accessed separately. To encourage migration to the new system, SaskTel is waiving device upgrade fees for current 10-4 customers making the switch.
