System capacity and
resistance to wireless
interference
When the following conditions exist simultaneously:
■ Five pairs of monitors and telemetry devices can communicate in 10 m
2
space,
with the monitors communicating with the Central Station via Wi-Fi. Note that the
telemetry devices can be devices such as TM80 and BP10.
■ The distance between the interfering devices and the monitor is greater than 20
cm. The interfering devices include but are not limited to: MPAN devices, remote
controllers, microwave ovens, interphones, operator’s network devices, cordless
phones, and ESU equipment.
the following requirements must be met:
■ The distinct vision distance between the monitor and the BP10 or the TM80 shall
be greater than or equal to 5 meters.
■ The code error rate of MPAN communication: ≤ 0.1%.
■ The data delay: < 1.5 seconds
MPAN network stability When five pairs of monitors and telemetry devices communicate in 10 m
2
space and the
monitors are communicating with the Central Station via Wi-Fi, the following
requirement must be met:
■ The time percentage when a monitor encounters MPAN communication loss shall
not exceed 0.1% over a 24-hour period.
■ The distinct vision distance between the monitor and the BP10 or the TM80 shall
be greater than or equal to 5 meters.
