Product Advantages
TB2I is specially designed for elevator wireless video transmission and customized
products; compared with the traditional elevator video transmission products, it has the
following advantages:
1.
G ood anti - jamming ability
S uper low frequency power supply interference, electrical spark interference, inverter
motor interference, control signal interference etc. that below tens of kilohertz are found in
the elevator environment, the use of W IFI high-frequency transmission, can effectively
avoid the interference of elevator environment. At the same time the device supports
extended frequency, can avoid the same frequency interference in the traditional W IFI.
2.
S hort construction period
In the absence of a large amount of wiring work, so greatly shorten the construction period,
save a lot of human resources.
3.
Embedded VTrans technology
TB2I devices is embedded with VTrans technology, including TDMA, 20M/40MH z
bandwidth, intelligent rate control, Auto AC K Time-out adjust. It makes the device have
longer transmission distance, higher throughput and better point-to-multi-point
performance.
4.
Embedded hardware watchdog
TB2I is embedded with hardware watchdog, which is used to monitor the working status
of the device. O nce the system is not working properly, the device can be rebooted to
guarantee the stability of the system.
5.
More N on-standard channels availability
C urrently most of the W IFI devices are working at standard 802.11 5.8G H z frequency.
H owever, standard 802.11 5.8G H z only provide limited channels, and there is serious
interference if there are a lot of 5.8G H z W IFI devices nearby. TB2I support more channels
near 5.8G H z band, and spread the band to non-standard frequency part. The advantage
of working at the non-standard band is to avoid the interference in the standard channels,
and the wireless throughput can be improved.
N ote:
Please confirm whether those non-standard channels are permitted locally before
using them.
