It allows several units to share the same frequency channel by dividing the signal into different time slots. The units transmit and receive on the same frequency in a synchronized manner. Every unit transmits in its own dedicated time slots. On the other time slots said unit receives the transmission sent by the other units that are members of the same network (which are also transmitting on their own dedicated slots). TDMA requires a synchronization system. The system is synchronized internally, externally or via GPS (synchronization varies between topologies and method used). The SkyHopper Pro unit uses TDMA regardless of the application type, PTP or PTMP. Page : 17 / 31 User Manual PTP (Point-to-Point) A PTP network is a radio link between 2 SkyHopper Pro units. The configuration (frequency and profile) of both units must be the same with only one difference - one unit is configured as a Remote Unit while the other unit is configured as a Controller Unit. The Remote Unit works with its internal clock and synchronizes the Controller Unit. After power-up, the Remote Unit starts transmitting regardless of link status. The Controller Unit however, does not transmit and stays in Rx mode, trying to acquire synchronization by finding a preamble (synchronization pattern). As soon as the Controller Unit recognizes the pattern, it starts to transmit according to its allocated time slot. The transmission bandwidth ratio is predefined as part of the profile configuration. It can be symmetric when full duplex communications are required (50% to each unit) or asymmetric up to 10% to one unit (remote or controller) and 90% to the other unit. Remote Unit Controller Unit Figure 5: Transmit frames of the remote unit and controller unit from Power Up Note: A viewer unit acts like a Controller unit but with one major change, it does not transmit and only receives. Page : 18 / 31 User Manual 7.1 PTP Link Step-by-Step Configuration In order to build a PTP link, two SkyHopper Pro units are required. One unit acts as a remote unit, while the other as a controller unit. 1. Connect antennas to RF1 and RF2 connectors, and power up the unit. CAUTION – Powering up a unit without connecting the antennas can cause irreparable damage to the unit. 2. Connect the unit to a PC using a standard Ethernet Cat 5 cable. 3.
