O4V3.0 supports PoE 802.3af/at, 12V 1A Passive PoE and 12V 1A DC power supply optional.
It helps the engineer to deployment the device flexiblely.

O4V3.0 adopts of internal power amplifier and 12dBi directional antenna to provide an efficient way to pick up and maintain a stable signal for a wireless network up to 5km.

For single pack, Tenda proprietary auto-bridge technology, makes the CPE or basestation in factory default settings connect to each other automaticaly after the device is powered on. For kit pack, the two CPESs inside are pre-configured at the factory, so plug and play is supported without manual pairing. It is very useful for the person who is not familiar with network knowledge, especially for CCTV surveillance transmission application.

TD-MAX is Tenda TDMA (Time Division Multiple Access) proprietary protocol to improve performance and capacity for wireless P2MP outdoor application scenarios. In outdoor enviroment, the CPE use highly directional antennas to connect to the Basestation from distances that can span several kilometers. the CPE can't sense each other, they become "hidden nodes" and cannot coordinate access to the wireless channel. Thus the Basestation experiences frequent collisions from stations transmitting simultaneously. As the network scales, these collisions build up exponentially, increasing latency and lowering throughput. With TD-MAX, it coordinate all the data transmission and allocates time to active clients to provide greater noise immunity performance when compared to the conventional 802.11 CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) protocol.
