4.2 LibraPlus Point-to-Point ( P-P) Systems
For P-P systems LibraPlus comes in two versions, the Rapid Deployment (RD) and the
Extended Range (ER) units. P-P links are used when only two locations are connected,
for example for backhaul purposes between P-MP Base Stations and the Network
Operating Center for connection to the I nternet backbone, or in situations where
throughput requirements between two locations are such that the bandwidth can’t be
shared.
4.2.1 EPPS Technology
The LibraPlus 5860 is engineered with EI ON's proprietary EPPS (EI ON, Protocol,
Protection, Speed) technology for an ultra-secure connection that optimizes the
maximum amount of bandwidth available for point-to-point applications. EPPS
technology was developed using the latest in encryption and security methods to
prevent malicious or non registered users from eavesdropping or intercepting signals.
To provide extra security and high quality link performance, EPPS devices contain the
following enhancements:
1. When using WPA2, EPPS will initiate a periodic key exchange for added security
against intrusion.
2. With EPPS, the encryption and authentication algorithms are implemented in the
hardware layer of the LibraPlus 5860, so that radio performance (speed) is not
impacted by the authentication process.
4.2.2 LibraPlus Rapid Deployment (RD) Equipment
The RD equipment is intended for very rapid installation of a P-P link and can be used
for links of up to 25 km (up to 3 km at full 60 Mbps actual bandwidth). RD Equipment
has two parts: 1) RD and 2) Ethernet Power Inserter with CAT-5 cable (bought
separately) and weatherproof ing kit (included).
• LibraPlus RD: The RD is the main piece of equipment that is normally
installed outdoors (indoor installation is permitted when the range and link
budget allows it). The RD contains all of the necessary radio equipment to
provide a high-speed wireless link. The RD also has an integral 23 dBi antenna
such that no RF cables are required for a typical installation.
• Ethernet Pow er I nserter: This piece of equipment is a small box that
connects between the RD and the Ethernet network. This box also provides
power for the RD equipment to run. A CAT-5 outdoor cable is used to connect
the Power inserter to the RD. The weatherproof ing kit is used with standard
RJ-45 connector to ensure reliable connection for outdoor systems.
4.2.3 LibraPlus Extended Range ( ER) Equipment
The ER Equipment allows for the use of different external antennas to achieve links of
much longer range (up to 50 km). I t can also be used for indoor installation of the units
should severe weather conditions require it. The antenna is then mounted outdoors
and connected via appropriate RF cables to the unit.
The LibraPlus ER consists of three parts: 1) ER, 2) Ethernet Power Inserter with CAT-5
cable (bought separately) and weatherproof ing kit (included), and 3) the External
Antenna and cable (both bought separately).
• LibraPlus ER: The ER is the main piece of equipment. I t is designed for
