Point to Multipoint (PTMP):


Point-to-multipoint communication is a term that is used in the telecommunications field refering to a communication which is accomplished via a specific and distinct type of multipoint connection, providing multiple paths from a single location to multiple locations. Point-to-multipoint is often abbreviated as P2MP, PTMP, or PMP. 

Point-to-multipoint telecommunications is most typically used in wireless Internet and IP Telephony via gigahertz radio frequencies. P2MP systems have been designed both as single and bi-directional systems. A central antenna or antenna array broadcasts to several receiving antennas and the system uses a form of Time-division Multiplexing to allow for the back-channel traffic. 

More recently, the term point-to-point telecommunications relates to wireless data communications for Internet or Voice over IP via radio frequencies in the multi-gigahertz range. It also includes technologies such as laser for telecommunications but in all cases expects that the transmission medium is line of sight and capable of being fairly tightly beamed from transmitter to receiver. 

Point to Multipoint (PTMP) links are easily established via all products. But the best choices are Q and D(Quad and Dual Radios). 
Depending on the total clients quantity and the desired coverage angle and overlapping factor one can chose between D and Q or a combination of both . 
Based on the application one can transfer Video, Voice or/and Data between two distant sections of a discrete network. 
Typical radius of PTMP links are relative to many environmental (Humidity, Noise,..) and technical (Antenna gain ,Tx output power,..) and the maximum distance can reach up to more than 50 Km in case of direct Line of Sight between two points.
