Page 9: Introduction
32mi/ 50 km or more in repeated applications. This radio integrates seamlessly with POTS voice cards and Leased Line cards, V.35 protocol or standard 10baseT Ethernet devices. CWT provides competitive price and performance solutions for many of the world’s telecommunication needs in both point-to-point and point-to-multipoint applications. - Page 10 The low power consumption of 2 Watts makes the units very energy efficient. They accept any DC voltage from 12V to 24V and are thus easily powered by solar. CWT solar powering kits are available with up to 7 days of back-up power. Flexible & Programmable All Trailblazer models are bench or field programmable.

Page 11: General Specifications
10BaseT On-Board Ethernet Port On-board Ethernet satisfies simultaneous LAN / IP data and PCM voice needs with an Industry Standard RJ45 10BaseT connection. Some of its advanced features include 802.3 Ethernet supported by Transparent LAN bridging and Automatic LAN MAC address filtering at the MAC level, making it transparent to higher level protocols such as TCP/IP, DECnet, NETBIOS, and IPX network protocols. -
Page 12: Pretest And System Planning
2 Pretest and System Planning 2.1 Site Requirements and System Planning 2.1.1 Grounding A ground is a low impedance electrical connection to earth that is used to dissipate energy. Grounding your Trailblazer is very important for safety reasons as well as to protect your system from damage due to lightning and static charge build up. -
Page 13: Line Of Sight
2.1.3 Line of Sight Visual line of sight (LOS) is the straight, unobstructed line between the Base unit’s antenna and the CPE’s antenna. In other words, when you stand next to one antenna, you can see the other one. Because RF waves spread out three dimensionally rather than in a straight line, LOS is important in microwave transmission but not adequate. -
Page 14: Path Loss
50.0 80.5 24.0 16.2 Table 2: Fade Margin Chart You can also calculate your own path loss using the integrated radio link margin calculator included on the CWT product CD in a folder called “Calculators”. Trailblazer Installation and User Manual... -
Page 15: Interference
What’s an acceptable fade margin? A rule of thumb theory is that 10 dB of fade margin will deliver about 90% reliability, and 20 dB will deliver about 99% reliability. Because there is only a small ground wave component involved in the radio propagation at 2.4 GHz, the above numbers presume both clear LOS (line of sight) and clearing at least 60% of the first Fresnel zone. -
Page 16: Data Cable Recommendations
LMR400 will work fine. Heliax™ is recommended for any cable runs over 100 feet. The chart below provides the loss factor for several popular cable sizes. Coax Cable Attenuation (dB per 100 feet) Cable Type at 2.5 GHz at 5.8 GHz LMR 400 6.8 dB 10.8 dB... -

Page 18: Powering The Trailblazer
Ohm’s law. For example, if you provide 12VDC you consume 2/12 A or about 167mA. If you provide 24VDC you use about half of that or 85mA. CWT recommends providing at least 4 times the power consumption. The Trailblazer consumes 2 Watts. -
Page 19: Connecting The Pots Lines
You can also power your Trailblazer by using several of the unused voice/data pairs in a standard 6 pair telephone cable. Don’t forget to allow for additional current if add-on card options are selected. The standard 6 pair telephone cable is made of 22 AWG size copper. This means that both legs will have 3.2 ohms of resistance per 100 feet. -
