Class B+ Technology
Why choose Class B+ ?
SOTDMA technology – same technology used by class A with guaranteed time slot allocation. Class B has to wait for a transmission space to be allocated. Class A is always prioritised and where commercial vessels are operating (just where you need AIS) waits may be excessively long.
5 W transmission power. Assuming an efficient AIS aerial system Class B can transmit further, 8 to 12 miles, for Class B this is likely to be 4 to 6 miles. – reception for both systems is the same 16 miles+, however, depends upon aerial system and installation height.
Increased transmission rate. Faster refresh rates which increase with speed – better for all craft and essential for high speed craft. Example: high speed craft at 23+ knotts refreshes every 5 seconds, Class B = every 30 seconds + wait time for a transmission slot.
