1 Product Overview
1.1 Product Advantages
TB 2 I is sp e c ially d e s igned fo r e le vato r wirele s s vid e o transmission and customized
products; compared with the traditional elevator video transmission products, it has the
fo llo wing ad vantage s :
1. Good anti - jamm ing ab ility
Super 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-fre q ue nc y trans mis s io n , c an e ffe c tive ly
avoid the interference of elevator environment. At the same time the device supports
extended frequency, can avoid the same frequency interference in the traditional WIFI.
2. Short 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/40MHz
b and wid th, inte llig ent rate c o ntro l, A uto A C K Time-out adjust. It makes the device have
longer transmission distance, higher throughput and better point-to-m ulti-p o int
p erfo rmanc e.
4. Embedded hardware watchdog
TB2I is embedded with hardware watchdog, which is used to monitor the working status
of the device. Once the system is not working properly, the device can be rebooted to
guarantee the stability of the system.
5. M o re N o n-standard channels availability
C urrently mo st of the WIFI devices are working at standard 802.11 5.8G Hz frequency.
However, standard 802.11 5.8G Hz only provide limited channels, and there is serious
interference if there are a lot of 5.8G Hz WIFI devices nearby. TB2I support more channels
near 5.8GHz 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 channe ls are p e rm itte d lo c ally b e fo re
using them.
