1: Introduction
• Integrated, high-gain, active diversity antenna - There are many advantages to the
EUM3006’s integrated antenna:
• Integrated, so that there are no RF losses due to long cable runs.
• High-gain (10 dBi), so that the EUM3006 can generate the maximum RF
signal allowed by FCC and increase the overall operating range.Active
diversity, which is done on a packet by packet basis, so that the EUM3006
performs better in a multi-path fading environment.
• Active diversity, which is done on a packet by packet basis, so that the
EUM3006 performs better in a multi-path fading environment.
• Polarization diversity, so that the installer need not worry about what
polarization the CCU is. Sector polarization can be readily changed at the
base stations, with the EUMs automatically adjusting.
• Power over Ethernet (PoE)- The EUM3006 is powered by standard 48 VDC Power
over Ethernet (802.3af Mode B compatible). Since the antenna is integrated, there is
no need for an RF cable. With PoE, there is no need for a separate power and
Ethernet cable. So the EUM3006 has only one standard, unshielded, flexible CAT-5E
cable, making installation simpler.
• 48 VDC PoE - Using 48 VDC power allows the EUM3006 to have up to 100 m of
Ethernet cable to the end-user’s PC, which is the maximum by the Ethernet standard.
The PoE injector can be located anywhere along this 100 m of cable. This provides
great flexibility in placing the EUM3006 to get the best RF signal. Systems that use
less than 48 VDC restrict the length of Ethernet cable due to voltage losses along the
cable.
• Higher RF Power - As a result of changes to the FCC rules, the EUM3006 makes
best use of its high-gain antenna to generated a full 36 dBm AVERAGE EIRP
(Effective Isotropic Radiated Power) out of the antenna. This represents an increase
of about 2.5 dB from the previous generations of EUMs with approved high gain
antenna systems.
• Improved RX Sensitivity - Each EUM3006 is tested to ensure that its RX Sensitivity
is -89 dBm or better (average received signal). Combined with the antenna gain of 10
dBi, the EUM3006 can receive signals at -99 dBm.
• DHCP Client enabled (factory default)- The EUM3006 can obtain its IP address,
subnet mask and IP gateway information from a DHCP server, reducing the amount of
configuration needed for installation. This also allows the Network Operator to re-
assign IP addresses to EUMs without having to access the EUM itself.
• Auto CCU Discovery (factory default) - The EUM3006 searches the full RF
frequency range to locate CCUs. It then selects the CCU with the best RF signal that
allows it to register. With this and DCHP Client enabled (factory defaults), the installer
does not need to enter ANY configuration parameters into the EUM3006 in order to
install it.
• Automatic Remote Configuration - The EUM3006 will accept parameters from a
RADIUS server to set other configurable parameters in the modem. These
parameters include: password, all SNMP parameters, RF Frequency (including
enabling Auto CCU Discovery), and number of customers. To use this feature, the
CCU must use software version V6.0 or later.
