1.Introduction
GeoNet is a low-power wireless data hosting system, designed to efficiently collect data from many points. GeoNet is especially helpful in geographically-complex locations where a wired infrastructure would be expensive or even impossible. Available network components include a Cellular Gateway, Local Gateway, single- and/or multiple-channel Mesh Vibrating Wire (VW) Loggers, Mesh Addressable Loggers, a Mesh Tilt Logger, and Agent software.
Model 8800 Series loggers collect data from geokon's VW gauges and sensors.
The Mesh Tilt Logger contains an integrated geokon biaxial tiltmeter, and functions in the same manner as other loggers.
The Cellular Gateway contains a cellular module enabling it to send sensor data to the geokon cloud. The device stores battery and temperature data sent from the loggers, and data from the sensors, but it does not possess sensor-reading functionality on its own. Data can be retrieved using the geokon cloud, or manually using a cable.
The Local Gateway is the same as the Cellular Gateway except it lacks a cellular module. Data must be retrieved manually via a direct cable connection.
Features:
■Supercapacitor eliminates data blackout during battery replacement
■Up to 26 km (6.5 km x 4 hops) range, line-of-sight
■Modular, configurable design
■Aluminum enclosure for enhanced ruggedness and weatherproofing
■Up to 12 networks per area (using unique channels)
■USB connector for firmware updates, diagnostics, and more
geokon recommends that you configure your network with the devices at the same location, in close proximity to each other, before you deploy them to their respective on-site positions.
An installation tutorial on the geokon website, https://www.geokon.com/tutorial-videos, can help with this.

CAUTION! To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.

1.3Mesh Tilt Logger Serial Numbers
Mesh tilt loggers have two serial numbers: one for the device as a whole, and one for the internal tiltmeter. The device serial number label is below the model number label; the internal tiltmeter serial number is below the calibration date label. See the figure below.
