Operational Characteristics
Hopping mode
A user serial number is used to generate a 70 hop long pseudo random hopping sequence which is
contains each channel exactly once and is repeated every 70 hops.

The RCM24G module is designed to work in the following diversity mode: Two adjacent modules
transmit parallel with full power. The pseudo random hopping frequency along with dissimilar seeding
ensures that both modules never occupy the same channel at a time. CCA is not performed.

FCC and ISED Statement
This digital apparatus does not exceed the Class
B limits for radio noise emissions from digital
apparatus set out in the interference-causing
equipment standard entitled “Digital Apparatus,”
ICES-003 of the Canadian Department of
Communications.
Cet appareil numérique respecte les limites
bruits radioélectriques applicables aux appareils
numériques de Classe B prescrites dans la
norme relatives aux interferences causée par du
matériel: “Appareils Numériques”, NMB-003
édictée par le Ministre Canadian des
Communications.
i. the device for operation in the band 5150-5250
MHz is only for indoor use to reduce the
potential for harmful interference to co-channel
mobile satellite systems;
i. Le dispositifs fonctionnant dans la bande
5150-5250 MHz sont réservés uniquement pour
une utilisation à l’intérieur afin de réduire les
risques d’interférence préjudiciable aux
systèmes de téléphonie satellitaire utilisant les
mêmes canaux;
ii. high-power radars are allocated as primary
users (i.e. priority users) of the bands 5250-5350
ii. De plus, les utilisateurs devraient aussi être
avisés que les utilisateurs de radars de haute
puissance sont désignés utilisateurs principaux
This device complies with Part 15 of the FCC Rules and with Industry Canada’s licence-exempt RSSs.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
Cet appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence.
L'autorisation d’exploitation est soumise aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de d’interférences radioélectriques, et
(2) l'appareil doit accepter toute interference radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le bon fonctionnement.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not in-stalled and used in accordance with the instructions, may
cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected
• Consult the dealer or an experienced radio/TV technician for help.

MHz and 5650-5850 MHz and that these radars
could cause interference and/or damage to LELAN devices.
(c.-à-d., qu’ils ont la priorité) pour les bandes
5250-5350 MHz et 5650-5850 MHz et que ces
radars pourraient causer des interférenceset/ou
des dommages aux dispositifs LAN-EL.
iii. for devices with detachable antenna(s), the
maximum antenna gain permitted for devices in
the bands 5250-5350 MHz and 5470-5725 MHz
shall be such that the equipment still complies
with the e.i.r.p. limit;
iii. Pour les dispositifs dotés d'antenne (s)
amovible (s), le gain d'antenne maximal autorisé
pour les dispositifs dans les bandes 5250-5350
MHz et 5470-5725 MHz doit être tel que
l'équipement soit toujours conforme aux normes
e.i.r.p. limite;
iv. for devices with detachable antenna(s), the
maximum antenna gain permitted for devices in
the band 5725- 5850 MHz shall be such that the
equipment still complies with the e.i.r.p. limits
specified for point- to-point and non-point-topoint operation as appropriate
iv. Pour les dispositifs dotés d'antenne (s)
amovible (s), le gain d'antenne maximal autorisé
pour les dispositifs de la bande 5725- 5850 MHz
doit être tel que l'équipement soit toujours
conforme aux normes e.i.r.p. Limites spécifiées
pour les opérations point à point et non point-àpoint selon le cas
Important Note
Changes or modifications made to this equipment not expressly approved by Intel Corporation may
void the FCC authorization to operate this equipment.
The product is provided with an approved antenna. Use only supplied or approved antenna by Intel
Corporation. Any changes or modifications to the Antenna may void the FCC regulatory approvals
obtained for the product.
End-users and installers must be provided with antenna installation instructions and transmitter
operating conditions for satisfying RF exposure compliance.
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least
20 cm from all persons. RF exposure compliance must be ensured by integrator.
