Carlson Wireless USA revision 1.05 Page 5 The i-WLL breakthrough offers many advantages not found in the market to-day: •Never needs tuning because i-WLL is a 100% digital, self-configuring, eight channel system. This simplifies installation and greatly reduces the need for maintenance and service over time. •Complete privacy is assured by the fully encrypted, spread-spectrum modulation scheme. •Highly efficient spectrum use from a unique combination of FDMA and CDMA. •Seamless integration with the global telephone network assured by i-WLL’s worldwide ISDN system architecture with full 144 kbps bandwidth. •No individual license needed for operation - i-WLL uses the globally li-cense-free 2.4 GHz ISM frequency band. •Flexible voltage – low power usage - just 3 to 6 Watts at any DC voltage between 12 and 55V. •Small, lightweight, self-contained units make i-WLL easy to install - no special expertise needed. i-WLL FXO (central office) and FXS (subscriber) units - which include all electronics, antenna and RF ca-bling - are housed in a weatherproof enclosure 4.5" in diameter by 30" long (11.5 x 76.2 cm) .

Carlson Wireless USA revision 1.05 Page 6 SYSTEM PLANNING Certain requirements are necessary for the i-WLL-15 system to function. (1) A radio path with losses fitting within the capacity of the system. We have a chart showing various antenna and distance combinations. What’s an acceptable “Link Margin“? An accepted theory is that 10 dB of fade margin will deliver a 90% reliability and 20 dB will deliver a 99% reliability etc.. There are other factors that affect this including vertical or horizontal po-larization. At 2.4 GHz there is only a small ground wave component involved in the radio propagation. This means that the above numbers are presuming clear LOS (line of sight). Multi-path occurs when a reflector such as earth’s terrain or man made structures cause additional delayed signals to be re-ceived. If a signal was delayed 180 degrees out of phase with the line of sight signal, and the magnitudes are the same, they will cancel out completely! In the real world, if you do have line of sight path, multi-path degradation is the reason why you need a minimum of 6 to 10 dB of margin. If you don’t have line of sight, multi-path could easily cause 20 dB of degradation.

Carlson Wireless USA revision 1.05 Page 14 Carlson Wireless USA revision 1.05 Page 7 (2) Other users of the 2.400 to 2.483 GHz ISM band. The ISM or Industrial, Scientific, and Medical band, is shared with many other type of services. Fortunately most of the users are located in urban areas, leaving sharing concerns down to consumer microwave ovens and other spread spectrum rural telephone users. The I-WLL-15 system has divided the ISM band into 8 sub-bands or channels. One channel is used for system ad-ministration with the system then randomly selecting 1 of the 7 remaining channels for operation. The functionality of the i-WLL–15 system de-pends on the existing and forecasted spectrum usage in the radio path. Due to the characteristics of the spread spectrum radio, the ITU (International Telecommunication Union) was able to coordinate this band globally for unlicensed use. This means that any user has to accept all other users in this band, interfering or not. (3) Availability of telephone service and power. The I-WLL-15 system consists of two units. One is designed to connect to the standard phone lines provided by a local telephone company office (FXO side) and the other connects to the telephone instruments such as; DTMF (touch tone) telephones, fax machines, and computer modems (FXS side) via individually twisted pair phone/data cable. The system is very flexible about voltage requirements. 12 to 55 Volts DC with the current being inversely pro-portional to the voltage, the power use being approximately 3 Watts for the FXO side, in any state, and 3 to 6 Watts for the FXS side depending on us-age state. We recommend over-sizing the supply by 1.5 to 2 times. Depend-ing on the length, most installations can use 4 twisted pair, #22 AWG feed cable. This will drop about 1 volt per 100 feet of length. To allow for most any voltage drop situation we recommend 24 volt, 500 mA power supplies. Using non-twisted IW or Quad phone wiring will result in cross-talk between lines. (4) Mounting structure. Warning! Use extreme caution to avoid contact with any high voltage power lines when constructing antenna structures! The enclosure is designed to mount on a steel vertical pipe, commonly known in North America as 1 to 2 inch pipe ( 2.5 to 5 cm ), with an actual outside diameter of 1.3 to 2.5 inches ( 3 to 6 cm ). This mast must not move signifi-cantly in any anticipated wind and must be connected with a short copper #8 AWG wire to a copper clad ground rod driven at least 6 feet (2m) into moist earth.

Carlson Wireless USA revision 1.05 Page 8 INSTALLATION Note that the installation of the FXO and FSO units are similar (1) Connecting the feed cable to the outside unit. On the mounting end of the tube there is an end cap with a weather sealing clamp. This allows the feed cable the penetrate the housing and remain sealed to outside weather. Begin with the removal of the rear end cap by using a coin as a wedge and working your way around the tube until the end cap pops off. Inside the end is the electronics assembly consisting of the printed circuit boards and inte-grated antenna. There are two screw down terminal blocks on the exposed end. One block has 2 connections and it is where the DC power supply con-nects. The other block has 4 connections, for telephone lines 1 and 2. The following diagram shows how to wire the connectors. Make sure to hand tighten only the weather sealing cord grip. Note: Make sure that the antenna elements are vertical or perpen-TIMESAVER TIP! By installing the FXO unit first, you can test the sys-tem locally by temporarily connecting the FXS unit up at the FXO site and proving your connections. This can greatly simplify any trouble shooting you may have later.

The antenna mast must also be grounded in the same fashion by a separate grounding rod. However if the run is longer than 35 feet or the location is in a highly active lightning area then a standard 3 way gas tube protector must be added. Connecting information on this device is provided by it’s manufacturer. (2) Connecting the feed cable to the inside equipment. Inside the building the feed cable is brought out to a terminal block consisting of 4 pairs of screw down connections. The following diagram shows how to wire the connectors.

Carlson Wireless USA revision 1.05 Page 10 (4) Rough alignment. This is usually easier then it would seem. Since it is a prerequisite that you have line of sight between the two points, here are sev-eral ideas that have worked for installers: (1) If you can see the other unit, simply aim the tubes towards each other. (2) During midday, use a large mirror to create a bright reflection approximately towards the other site while someone watches for the flash. (3) Plot out the path on a topo map and set the antennas using a compass. How close in alignment do they need to be? +/- 10 degrees will be ade-quate for most paths using the 13.5 dB gain antenna. Certain paths that have a low fade margin may require a more accurate setting. Final alignment. This is usually done by connecting a standard cordless phone to the FXS or FXO end, and then give a best guess to the direction, establish a connection and rotating the antennas both right and left noting the points where the signal disappears, (assuming that it does) and then center-ing them between those cutoff points. Remember to leave the antenna elements vertical, or perpendicular to the ground for best performance Carlson Wireless USA revision 1.05 Page 11 TROUBLESHOOTING The outcome of the installation is dependent on the weakest link. Five things are paramount to his system working well: (1) An acceptable radio path (2) Other users of the 2.4 GHz ISM band. (3) Customer’s wiring of power and telephone circuits (4) Antenna alignment within +/- 10 degrees for i-WLL-15 (5) Quality of the telephone lines from the telephone company (6) Quality of the power supplies. If the system appears dead, with no tones audible on the subscriber phone, look for a wiring fault. You can test for loop voltage at the FXS end by meas-uring the voltage on line 1 and line 2. Each should be 30 VDC. Next would be checking the DC current used by each unit. For example the sub unit with 16 Volts provided should draw (3W / 16V) ~200 mA. at idle and ~400 mA with both lines off hook. This test is very useful to prove out the wiring. Next, it will be important to confirm that a local test at the FXO base site was done. If not, you will need to bring the FXS unit back to the base site and temporarily connect the FXS unit up and confirm proper local operation. If the system cuts in and out, or fails to draw dial tone, look for an alignment problem or path obstruction. Also you should check to see that the antenna elements are vertical to earth, and if not in a rural area you may have a con-gested frequency band. If you are having cross-talk between lines, examine the phone cabling making sure it is individually twisted pairs, preferably with a Category 5 rating. Software Updates: Inappropriate operations (bugs) reported by users will be evaluated by the engineering department. Fixes will be available from our web site with instructions If after checking the above, you are still having problems please contact our sales dept. for technical assistance by phone or email. A note about the power supplies: The FXO unit will draw 2-3W off hook or idle. The sub will draw 3W idle and 6W with both lines off hook. We suggest over-sizing the supplies by 2 times. For example a 12 volt filtered DC wall transformer supply @ 1.00 Amp (12W) or even better a 24 volt filtered DC @ 500 mA. (12W). They are much more likely to survive power fluctuations and high tempera-

Due to the characteristics of the spread spectrum radio, the ITU (International Telecommunication Union) was able to coordinate this band globally for unlicensed use. This means that any user has to accept all other users in this band, interfering or not. (3) Availability of telephone service and power. The I-WLL-15 system consists of two units. One is designed to connect to the standard phone lines provided by a local telephone company office (FXO side) and the other connects to the telephone instruments such as; DTMF (touch tone) telephones, fax machines, and computer modems (FXS side) via individually twisted pair phone/data cable. The system is very flexible about voltage requirements. 12 to 55 Volts DC with the current being inversely pro-portional to the voltage, the power use being approximately 3 Watts for the FXO side, in any state, and 3 to 6 Watts for the FXS side depending on us-age state. We recommend over-sizing the supply by 1.5 to 2 times. Depend-ing on the length, most installations can use 4 twisted pair, #22 AWG feed cable. This will drop about 1 volt per 100 feet of length. To allow for most any voltage drop situation we recommend 24 volt, 500 mA power supplies. Using non-twisted IW or Quad phone wiring will result in cross-talk between lines. (4) Mounting structure. Warning! Use extreme caution to avoid contact with any high voltage power lines when constructing antenna structures! The enclosure is designed to mount on a steel vertical pipe, commonly known in North America as 1 to 2 inch pipe ( 2.5 to 5 cm ), with an actual outside diameter of 1.3 to 2.5 inches ( 3 to 6 cm ). This mast must not move signifi-cantly in any anticipated wind and must be connected with a short copper #8 AWG wire to a copper clad ground rod driven at least 6 feet (2m) into moist earth.

Carlson Wireless USA revision 1.05 Page 6 SYSTEM PLANNING Certain requirements are necessary for the i-WLL-15 system to function. (1) A radio path with losses fitting within the capacity of the system. We have a chart showing various antenna and distance combinations. What’s an acceptable “Link Margin“? An accepted theory is that 10 dB of fade margin will deliver a 90% reliability and 20 dB will deliver a 99% reliability etc.. There are other factors that affect this including vertical or horizontal po-larization. At 2.4 GHz there is only a small ground wave component involved in the radio propagation. This means that the above numbers are presuming clear LOS (line of sight). Multi-path occurs when a reflector such as earth’s terrain or man made structures cause additional delayed signals to be re-ceived. If a signal was delayed 180 degrees out of phase with the line of sight signal, and the magnitudes are the same, they will cancel out completely! In the real world, if you do have line of sight path, multi-path degradation is the reason why you need a minimum of 6 to 10 dB of margin. If you don’t have line of sight, multi-path could easily cause 20 dB of degradation.
