Better Off With Map And Nokia (BOWMAN)
does work despite what the press has been saying (Oh my god, jounro's telling porkies? Never!).
(Nicked wholesale from another site):
Bowman in a nutshell:
1. Secure is a success. It is performing very well on operations, and consistently delivers better QoS over greater ranges than Clansman, which is a far inferior system in every way.
2. Data is utter bonk and will be for some time. Work is ongoing to improve the data service, as a technical solution already exists - but that's only half the story.
In sum, don't believe what you hear - it's actually going very well.
