pMXDDL2450 Regulatory Requirements - PLEASE READ THIS SECTION CAREFULLY WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 25 cm (38 cm co-location with LTE module), 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.
pMXDDL2450 Exigences Réglementaires WARNING: Pour satisfaire aux exigences d'exposition RF de la FCC pour les appareils de transmission mobiles, une distance de séparation de 25 cm (colocation de 38 cm avec le module LTE) ou plus doit être maintenue entre l'antenne de cet appareil et les personnes pendant le fonctionnement de l'appareil. Pour garantir la conformité, les opérations à une distance inférieure à cette distance ne sont pas recommandées.
Co-Location with Cellular Modems Co-location MPE conditions of EUT with 2.5 dBi dipole and LTE module were evaluated at 38 cm distance. The following were evaluated for mobile configurations: 1) EUT with 2.5 dBi dipole antenna co-located with LTE Data Card Module (FCC ID: XMR201808EC25AF, IC: 10224A-2018EC25AF) 2) EUT with 2.5 dBi dipole antenna co- located with LTE Data Card Module (FCC ID: XMR201903EG25G, IC: 10224A-201903EG25G) 3) EUT with 2.

2. General 2.0 Product Overview The pMXDDL2450 is a high-performance embedded wireless data transceiver. Operating in the 2400 – 2483.5 MHz ISM band, this frequency-hopping spread-spectrum module is capable of providing reliable wireless data transfer between almost any type of equipment which uses an asynchronous serial interface. The small-size and superior RF performance of this module make it ideal for many applications.
TDMA (time division multiple access) support, allowing multi-slave access in point-to-point mode. roaming ability, allowing repeaters and slaves to resynchronize with a new master if the synchronization pulse from the original master is lost. While the typical application for the pMXDDL2450 is to provide a short- to mid-range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. 2.
3. Installation 3.0 Overview The pMXDDL2450 complies with FCC part 15 at the modular level for operation in the license-free 2400-2483.5 MHz ISM band. This chapter provides guidelines for installing and deploying equipment which incorporates the pMXDDL2450 module. 3.
Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the pMXDDL2450 is -108dBm. System gain would be calculated to be: 30 - 2 + 6 + 3 - 2 + 108 = 143 dB.
Once the equipment is deployed, you can verify the signal strength by entering into Command Mode and reading Register S123. This register provides the average signal strength in dBm. The minimum strength for communication is roughly -108dBm. For consistent reliable communication, you should try to deploy the equipment such that signal strength exceeds -95dBm. 3.2 Antennas and Cabling This section describes the recommended procedure for installing cabling and antennas for use with the pMXDDL2450 module. 3.
3.2.2 WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 25 cm (38cm collocated with LTE module) 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 colocated in conjunction with any other antenna or transmitter.
WARNING: MAXIMUM EIRP FCC and IC Regulations allow up to 36dBm effective isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36 dBm with respect to the isotropic radiator. WARNING: The pMXDDL2450 can only be used with any antennas listed in Appendix A. WARNING: Be careful with dBi vs dBd gains on antenna specifications. Antenna manufactures may not clearly indicate the gain on the antenna if it is dBd or dBi.
8 pMXDDL2450 Operating Manual
What is the maximum power the pMXDDL2450 can be set to comply with FCC and IC given the following equipment given a Omni Ant Gain 6dBd and cable and connector loss of 2.5 dB? Examples: FCC and Industry Canada Regulations allow up to 36dBm effective isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36dBm with respect to the isotropic radiator.
A. Approved Antennas This radio transmitter (IC:3143A-PMXDDL2450) has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.
