2.2. Hardware parameters of ZRadio
The parameters described in this section are set using the hex rotary switches on the radio modem. The meaning of the setting switches (Figure 3) is identical on the ZRadio-F and the ZRadio Sx or ZRadio S except for the OPM switch. The specifications for the required setting of the modem are to be stored at the installation site of the respective ZRadio modem. If the setting is changed while the ZRadio is switched on, this leads to a restart of the device with the new parameters after a maximum of 5s.

Transmission power TXP
The maximum transmission power EIRP(Equivalent, Isotropically Radiated Power) behind the antenna must not exceed certain limit values according to the applicable international regulations. For most countries in Europe, e.g., Germany, the maximum transmission power for the transmission method used here is limited to 10 dBm = 10 mW without separate restrictive measures for compatibility with third-party systems, such as LBT (Listen before Talk). In case of doubt, the current regulations for the country concerned should be obtained.

Depending on the components used, the power must be set on the radio modem using the coding switches in such a way that the maximum transmission power behind the antenna reaches the maximum permissible power as well as possible but does not exceed it. For this purpose, the antenna gain, and the attenuation of the components used between the radio modem and antenna, such as antenna cables, lightning protection modules, filters, must be considered. An additional attenuation of 0.1 dB is taken into account for each individual connector, which means that a complete connector has a typical attenuation of 0.2 dB.

For the components mentioned in this document, the attenuation for the connectors has already been taken into account and must not be included in the calculation a second time. The transmission power to be set must be specified for each vehicle type or each signal depending on the components used in a power budget (link budget) and specified in a data sheet for the respective place of use. This data sheet must be available as information in the area of the ZRadio modem, for example as a supplementary sheet or sticker in the signal switch box.

Radio channel pair CHP
The Zub radio upgrade uses two different frequency channels for a route equipped with Zub222c, one for direction 1 and one for direction of travel 2. These two channels form a radio channel pair that can be configured with the ZRadio and set using a hex rotary coding switch. Table 18 lists the 16 adjustable radio channel pairs with the associated frequencies for directions 1 and 2. Refer Table 8 for selectable radio channel pairs. The radio channel pairs 10 or 11 should be preferred. Operation on the following individual channels should be avoided for the time being:

· Channel 21 and, to a limited extent, channels 20 and 22: On this frequency, microwave ovens in kitchens with quite high power can interfere with the radio channel. The radio channel can then be “blocked” for 10ms every 20ms.
· Channel 12, Channel 17, Channel 22:These channels are most affected by WiFi transmissions in private networks (default settings)

Facility identifier RID
The telegram traffic between the ZRadios is transmitted with a system identifier. One of 16 possible identifiers is selected with the RID parameter. A common, fixed system identifier for all ZRadios must be defined for a customer system. It must be ensured that two customer systems with the same system detection do not overlap in the radio range. Under certain circumstances, this could also lead to a security risk.
It must also be taken into account here that overranges can also result from incorrectly increased transmission power. The same system identifier can be used for customer systems with a minimum distance of > 5 km. Possible expansions of the existing routes must also be taken into account.

3. Wi-Fi Patch Antenna
3.1. Function
The Wi-Fi patch antenna is used to transmit the track coupling coil information in advance to the vehicle. Signal aspect clearing from stop to proceed (change to a less restrictive signal aspect or radio infill) can thus be detected on the vehicle before reaching the transmission point and the braking curve to the transmission point can be canceled. The WiFi patch antenna is installed at the signal so that it can transmit and receive the information in parallel with the signal’s optical system and the installation space in front of the antenna is iron free +/- 30° in all directions. Antenna installation is done vertically with SMA connector.

Power supply
The radio module receives their power separately from the power supply of the signal box (24V DC). The TGMT Zub track coupling coils receive their power inductively from the passing vehicle coupling coil.
Ambient Temperature
On account of the low power consumption during operation no significant heat dissipation occurs. For the TGMT Zub wayside equipment, the following ambient temperature ranges are defined:
· ZRadio-Sx: -40°F to +158°F (-40°C…+70°C) · Radio-antenna: -40°F to +176°F (-40°C…+80°C) In order to ensure correct functionality, this temperature range must be observed, i.e., the ambient temperature must be within this range. The TGMT Zub wayside equipment complies with [EN 60068-2] · Part 2-1: Tests – Test A: Cold · Part 2-2: Tests – Test B. Dry heat · Part 2-14: Tests – Test N: Change of temperature

Humidity

The following humidity stresses apply in the installation room of the signal boards:

· Annual average = 75% rel. humidity

· 30 days in the year continuously 95% rel. humidity

· On the remaining days occasionally 85% relative humidity

· Infrequent and light condensation

These values comply with [EN 60068-2]

· Part 2-30: Tests – Test Db: Damp heat, cyclic.

The above-mentioned operation related infrequent and light condensation causes no malfunctions or failures.
