ONE: introduction 2 SPICE™ Hardware Guide 550008 Rev. A Littlefeet, Inc.
TWO system overview Ideally, a base station would provide coverage that tapers off uniformly (A, Figure 1). Variations in propagation make the actual coverage irregular (B, Figure 1). This leads to dropped calls due to excessive interference and low signal strength. figure 1. ideal versus actual coverage Littlefeet provides a way for base stations to communicate with mobiles using low-power SPICE units. SPICE handle the coverage functions of a traditional base station.

THREE safety This chapter details requirements for the safe installation and use of SPICE units. The safety of the unit, of the technicians working on the unit, and of the general public is addressed. CAUTION ! Make sure you read, understand, and observe the cautions and warnings described in this chapter as well as those found elsewhere in this documentation and on the unit itself. SPICE units transmit and receive signals via RF (radio frequency) energy.
THREE: safety RF exposure SPICE™ Hardware Guide 550008 Rev. A RF exposure Many studies have been performed regarding exposure to RF energy. Although all studies to date have been inconclusive as to the effects of RF exposure and human health, there is still some public concern. Since SPICE units operate at lower power than conventional base stations, there is less exposure to radiation.
SPICE™ Hardware Guide 550008 Rev. A THREE: safety unit safety unit safety In order to properly maintain a SPICE unit, follow the guidelines described below. Any failure to do so may void any warranties. water Do not expose the interior of the unit to water. Make sure that the service hatch (cSPICE) or door (bSPICE) is completely closed after installing or servicing the unit. Never remove the front cover from the cSPICE.
THREE: safety unit safety SPICE™ Hardware Guide 550008 Rev. A grounding Always make sure that the external power supply is properly grounded. Never plug the power supply into a two-pronged (non-grounded) outlet or use a two-conductor extension cable unless safety ground is attached to the stud on the power supply chassis. Failure to do so may result in a buildup of excess charge which may damage the unit or cause a potentially hazardous situation. The chassis of the unit must be grounded.
SPICE™ Hardware Guide 550008 Rev. A THREE: safety servicing the unit servicing the unit The only user-serviceable parts inside a SPICE unit are the wireless modem and the battery pack. Always wear a grounding (earth) strap when servicing the unit. CAUTION ! CAUTION ! Do not remove the front cover of the cSPICE unit. Open the service hatch on the bottom of the unit when servicing the cSPICE.
THREE: safety installation safety notes SPICE™ Hardware Guide 550008 Rev. A installation safety notes The following safety concerns must be taken into account when installing SPICE units. CAUTION ! SPICE units must be installed by carefully following the installation documentation and by noting the safety concerns described here. Failure to do so may result in harm to the unit, installer, or general public. Littlefeet is not responsible for any damages caused by improper installation.
SPICE™ Hardware Guide 550008 Rev. A THREE: safety installation safety notes • In an area where the ambient temperature is excessively high (for example, near smelting equipment). • Near an area where blasting caps are used. • Where overhead power lines will come within 3 to 6 feet (0.9 to 1.8 m) of antennas (depending on line voltage - check local codes).
THREE: safety general precautions SPICE™ Hardware Guide 550008 Rev. A general precautions In addition to the other precautions listed in this and other chapters, note and follow the following precautions. CAUTION ! Do not incinerate or crush units, as the batteries may explode and/or hazardous substances may be released. Contact Littlefeet for proper disposal instructions. Do not attempt to service the inside of the unit, other than replacing batteries or the modem’s SIM card.
FOUR installing SPICE This chapter describes how to install a SPICE unit at a predetermined location. You will need the configuration information from the Installation Form. note Units to be installed must already have a data-enabled Subscriber Identity Module (SIM) card inserted into the internal modem. To install the SIM, see “replace SIM card” on page 42, or the Quick Start guide that accompanies new units. CAUTION SPICE units must be properly connected to earth ground.
FOUR: installing SPICE installation overview SPICE™ Hardware Guide 550008 Rev. A installation overview Radio planning and site selection are not addressed in this manual, nor are software operations. note This chapter assumes that the site for the unit has already been determined. Once a site has been chosen and a power supply obtained and properly installed, mount the bracket and hang the SPICE unit. Check the power supply and connect it to the unit.

If only one antenna is provided, attach the single antenna to the connector. There will be a cover over the unused hole. figure 21.
FOUR: installing SPICE installing cSPICE SPICE™ Hardware Guide 550008 Rev. A figure 22. installed antennas customer-supplied antennas cSPICE units can also use customer-supplied antennas. Both link and coverage ports have Voltage Standing Wave Ratios (VSWRs) of better than 2:1 in the downlink and uplink frequency range. Customer-supplied antennas can have up to 2:1 VSWR in the downlink and uplink frequency ranges.
SPICE™ Hardware Guide 550008 Rev. A FOUR: installing SPICE installing cSPICE determine link antenna orientation The link antenna is found on the front of the cSPICE. Use a compass or other tool to determine the direction of the bSPICE from the cSPICE site. If the bracket cannot be mounted so the unit is facing the bSPICE signal, remove the link antenna from the front of the unit and mount it remotely. note The best signal is not always directly from the bSPICE direction.
FOUR: installing SPICE installing cSPICE SPICE™ Hardware Guide 550008 Rev. A The bracket must be mounted so that the arrow on the bracket is pointing up (Figure 25). figure 25. arrow on cSPICE bracket The cSPICE must be installed right-side up, never upside-down, on its side, or on its back or front (Figure 26).
