5.1.3 Subscriber Module

The Subscriber Module (SM) is a customer premises

equipment (CPE) device that extends network or

Internet services by communication with an AP. The

SM is configurable through a web interface.

An SM mounted directly to a structure is pictured in

Figure 2.

5.1.4 900-MHz AP and SM

Canopy 900 MHz AP and SM modules operate at 3.3

Mbps (compared to 10 Mbps for other Canopy frequency

bands). With Downlink Data set to 75% on the AP

Configuration page, the AP supports high throughput to

an SM.

These 900-MHz modules run the same software and

provide the same parameters, network features, and

connections as all other Canopy APs and SMs. The

physics of longer-wavelength 900 MHz, the power

allowed by regulatory authorities, and the low Canopy

Carrier-to-Interference (C/I) ratio combine to support:

◦ LOS range of 40 miles (over

64 km)

◦ increased NLOS range, depending on RF

considerations such as foliage, topography,

and obstructions.

When collocated with a Canopy SM of another frequency

band range, the 900-MHz AP may serve, without a tower

or BH, as a remote AP. The SM provides the Spectrum

Analyzer feature.

900-MHz modules operate on only the unique Canopy

System Release 4.2.2 or later releases, but can be used

in networks that also consist of modules in other

frequency bands operating on earlier Canopy system

releases.
