Page 10: Hardware Installation
2.0 Hardware installation This chapter describes: • The installation of the antennas • The installation and configuration of the WB-S1100 and the WB-C1100 units • Connecting the antennas to the units Before starting the installation, some understanding of antennas and their behaviour is necessary. -
Page 11: The Antenna Installation
Wireless LAN to LAN bridge Manual 2.1 The antenna installation 2.1.1 radiation diagram The bridge units are supplied with a choice of three different antennas. The type of antenna used depends on the type of link (point-to-point or point- to-multipoint) and the required range. All antennas are directional by nature; they cannot be made to radiate uniformly in all directions. -
Page 12: Multi Path
Wireless LAN to LAN bridge Manual 2.1.2 Multi path Direct Sequence technology is more sensitive for multi-path effects than the traditional Frequency Hopping. Multi-path effects can be explained as coherent signals (signals from the same source) arriving at the antenna at different times due to the difference in path length. - Page 13 Wireless LAN to LAN bridge Manual The gain of the antenna is directly linked to the range. According to the above table, it is clear that a dish should only be chosen when a distance of 3km or more needs to be covered. Locating the antenna Free space radiation patterns are the baseline performance criteria before installation in the real world environment.

Page 14: Free Space Losses
Wireless LAN to LAN bridge Manual 2.1.3 Free space losses Spreading is the principal contributor to signal loss for line of sight propagation. As a signal radiates it spreads or expands into a spherical surface. The available RF power is distributed over this surface and weakens with increasing range. -
Page 15: Line Of Sight
Wireless LAN to LAN bridge Manual 2.1.4 Line of sight Radio signals require a clear path between antennas. It is necessary to know the requirements of a clear path (known as ‘line of sight’). Line of Sight (LOS) means a bit more than the words say. Of course the first condition for a LOS link is that the two antennas can be connected with an imaginary straight string. -
Page 16: The Link Budget
Wireless LAN to LAN bridge Manual 2.1.5 The link budget For each link a ‘link budget’ needs to be made. The link budget will calculate the signal level through the link, and predicts the signal level at the receiver’s side. Within the ‘link budget’ there are a few parameters that are influenced by the location of the link. -
Page 17: Mechanical Installation Of The Antenna
Wireless LAN to LAN bridge Manual 2.1.6 Mechanical installation of the antenna A solid mechanical installation of the antenna is the base of a quality link. An outdoor mounted antenna is exposed to extreme weather conditions. Metal brackets oxidise, and vibrations will cause slack on connections. Therefore, the mechanical connection between the antenna and its carrier needs to be solid. -

Page 20: Basic Alignment Of The Antenna
Wireless LAN to LAN bridge Manual 2.2 Basic Alignment of the antenna Due to its directive behaviour an antenna needs to be aligned. Alignment is done by maximising the antenna signal and by minimising phase noise. The phase noise directly influences bit error rate. The alignment is essential because certain weather conditions can degrade the signal strength. - Page 21 Always use connector 1, Connector 2 is only used inspecial cases by an experienced installer. For information about using the second antenna option, please contact No Wires Needed. The left hand side LED displays the radio link status. The client function of this LED differs from the server.
- Page 22 Wireless LAN to LAN bridge Manual It is this function that is used for the first alignment. First, install the server side of the bridge. Aim the server antenna (unless it is an onmi antenna) towards the client side of the bridge. Then power up the server side. Secondly, the client side needs to be installed.

Page 23: Configuration Of The Bridge Units
Wireless LAN to LAN bridge Manual 2.3 Configuration of the bridge units This chapter describes the configuration of the bridge during alignment. This means that certain settings or parameters are not mentioned because they do no effect the alignment of the antennas. Chapter 3 will give a clear description of the meaning of each option, and when to change or use that option. -
Page 24: Antenna Settings
Wireless LAN to LAN bridge Manual In this menu the radio settings can be set. It contains the following options: SSID (name of the link, both sides need the same name) Encrypt using AirLock™ MAC properties Contention window (use if more data goes upstream than downstream) ACK window (use when large distances need to be covered) Short retry limit... -
Page 25: Fine Tuning Of The Bridge Link
Wireless LAN to LAN bridge Manual 2.4 Fine tuning of the bridge Link The link quality is measured via the Tuning tab. Two quality indicators are displayed. These are: RSSI (radio signal strength indicator) SQ2 (indication for quality of received signal) The tuning selection looks like this: Figure 2.10 Two lines are displayed. - Page 26 Wireless LAN to LAN bridge Manual Figure 2.11 The chart below displays the signal level versus the RSSI, SQ2, and the speed. Speed is displayed as a percentage of the maximum. If SQ2 displays 100%, the red line in the tuning screen displays 0. You can use this graph to determine if the throughput fits the RSSI and SQ-2 value the tuning function displays.

Celsius. Preferably mount the unit inside; if that is not possible use the outdoor housing. The housing supplied/advised by No Wires Needed contains a heating element and a sensor. The antenna is supplied with an antenna cable. Use this cable with your installation. -
Page 28: Bconfig Configuration Program
Wireless LAN to LAN bridge Manual 3.0 BConfig configuration program This chapter describes the configuration program of the bridge. This program allows you to install and maintain your bridge link. It contains an excellent performance monitor for fine-tuning and troubleshooting. Within this chapter all options in the program are described together with the circumstances in which it is useful to use these setting. -

Page 32: The Device Settings
Wireless LAN to LAN bridge Manual 3.3 The device settings The radio setting can influence the performance of the link. After installation it is essential to go through each parameter and determine the best settings. Some parameters are related to each other, this means that the best combination needs to be found. -
Page 33: Ack Window
Wireless LAN to LAN bridge Manual ACK window This is the waiting time for the acknowledgement, again expressed in slot time. 1 unit is 1slot time (roundtrip) and represents 3 km. Increase this number for large distances. 2 represents 6 km, 3 represents 9 km etc. It will not harm the link if the ACK window is larger than the corresponding distance. -
