Point to Multi-Point Wireless Configuration

Point to Multi-Point Wireless Configuration

The Motorola Canopy Point-to-Multipoint configuration is available in either the 2.4 Ghz or 5.2 GHz or the 5.7 GHz frequency bands. Either the 5.7 GHz or the 5.2 GHz system provide a Line of Site (LOS) range of approximately two miles (5.2 GHz) or ten miles (2.4 Ghz and 5.7 GHz with reflector) between the AP Module and SM using their internal Canopy antennas. The 5.7 Point-to-Multipoint configurations can support a 5.7 SM with the reflector kit (27RD) The reflector kit increases the transmit and receive gain of the SM by approximately 17 dB, thereby increasing the range between the AP Module and the SM to approximately 10 miles LOS. The Point-to-Multipoint system enables the delivery of broadband access to multiple locations from a single AP Module, each covering approximately 60 Degrees of coverage. The typical system, as shown below, was developed to optimize its performance in high density and low-density environments in the presence of external interference sources. Therefore, a Canopy Point-to-Multipoint configuration can be deployed in both rural and metropolitan environments. For more information, please contact us at (516) 214-0321.

	The Motorola AP Cluster is a base station that can incorporate between one and six AP Modules and up to two Backhaul Modules (BH). Each module operates with a 60-degree directional antenna to provide coverage to one sector. One of the unique capabilities of the Canopy system is its ability to synchronize the transmission timing of the AP Modules in all of the AP Clusters. The GPS receiver in the CMM is the key to delivering this system level synchronization. The synchronization of the AP transmission along with the specially designed Canopy Time Division Duplex (TDD) air interface ensures that all AP Modules transmit at the same time while all Subscriber Modules (SM) are in a listen mode. This synchronization also ensures that when the SMs are transmitting, all the AP Modules are listening. This synchronization, enabled by the Cluster Management Module (CMM), ensures that the Canopy system does not interfere with itself, since the AP Modules do not interfere with each other and the SMs do not interfere with each other. This unique characteristic delivers an ability to scale the network where Canopy AP Clusters can be added to the network to improve system coverage or capacity without increasing the system interference.
	The Canopy Cluster Management Module is an accessory for use in the Canopy wireless broadband system. It provides all of the necessary power, Ethernet connections, and GPS synchronization for up to 6 Access Point modules as well as 2 Backhaul modules. The Motorola Canopy Cluster Management Module 1008CK includes a GPS receiver, antenna for automatic AP synchronization, and built-in Ethernet switch. It also includes AC power supply.
	The Motorola Canopy Subscriber Module, is the subscriber termination unit or the Customer Premise Equipment (CPE). It consists of a single module that operates with an integrated 60-degree antenna. Each SM can communicate to a single AP Module at any given time. SM synchronization and control is accomplished via the received AP signal. SMs are typically located outdoor and Line of Sight (LOS) from the Access Points. Once the SM is initialized, it scans the Radio Frequency (RF) channels and automatically registers with the appropriate AP. Each SM requires a Category 5 cable for its Ethernet connection to the premise IP equipment with DC power supplied to the SM through that same cable. The SM uses a 110 VAC power supply (ACPS110-01 or -02) or the 90V-230V switching power supply (ACPSSW-01) and associated RJ45 connector to power the SM. The Universal Mounting Bracket (SMMB1) is available for mounting the SM to the customer site. One SMMB1 is required for each SM. It is recommended to use a Canopy Ethernet Surge Protector (300SS) mounted at the Ethernet entry point on the outside wall of the premise.
