ANNEX 2: TRACKING, TRACING AND DATA AQUISITION

Scope of annex
This annex covers frequency bands and regulatory as well as informative parameters recommended for tracking, tracing and data acquisition applications including: - Emergency detection of buried victims and valuable items such as detecting avalanche victims; - Person detection and collision avoidance; - Meter reading; - Sensors (water, gas, electricity, meteorology, pollution, etc.) and actuators (controlling devices such as street or traffic lights, etc.); - Data acquisition; - Wireless Industrial Applications (WIA) to be used in industrial environments including monitoring and worker communications, wireless sensors and actuators.

Frequency Band Power / Magnetic Field Spectrum access and mitigation requirements Modulation / maximum occupied bandwidth ECC/ERC Deliverable Notes
a1 442.2kHz  -  450kHz
7 dBµA/m at 10m No requirement Continuous wave (CW) - no modulation, channel spacing ≥ 150 Hz Person detection and collision avoidance
a2 456.9kHz  -  457.1kHz
7 dBµA/m at 10 m No requirement Continuous wave (CW) at 457 kHz - no modulation Emergency detection of buried victims and valuable items
b 169.4MHz  -  169.475MHz
500 mW e.r.p. ≤ 10% duty cycle ≤ 50 kHz ECC/DEC/(05)02 Meter Reading. The frequency band is also identified in Annex 1
c1 865MHz  -  868MHz
(note 4)
500 mW e.r.p. (note 5) ≤ 10% duty cycle for network access points (notes 6 and 7) ≤ 2.5% duty cycle otherwise ≤ 200 kHz Data acquisition in data networks. The APC is able to reduce a link’s transmit power from its maximum to ≤ 5 mW. The frequency band is also identified in Annexes 1, 3 and 11
c2 870MHz  -  875.6MHz
(note 8)
500 mW e.r.p. ≤ 2.5% duty cycle and APC required (note 1). For ER-GSM protection (873-875.6 MHz, where applicable), the duty cycle is limited to ≤ 0.01% and limited to a maximum transmit on time of 5ms/1s (note 2) ≤ 200 kHz Data acquisition in data networks. Individual license may be required for Metropolitan/Rural Area Networks. Adaptive Power Control (APC) required. The APC Control is able to reduce a link's transmit power from its maximum to ≤ 5 mW. The frequency band is also identified in Annex 1
d 5725MHz  -  5875MHz
≤ 400 mW e.i.r.p. APC required Adequate spectrum sharing mechanisms (e.g. DFS and DAA) shall be implemented (note 3) ≥ 1 MHz and ≤ 20 MHz Wireless Industrial Applications (WIA). Registration and/or notification may be required. The Adaptive Power Control is able to reduce the e.i.r.p. to ≤ 25 mW. The frequency band is also identified in Annex 1

Note 1 A duty cycle of up to 10% may be allowed for network relay points forming part of metropolitan/rural area networks such as for utilities or other applications for the purpose of data acquisition. Network relay points should be individually licensed. National regulatory authorities may consider the provision of general authorisations (options as defined in ECC Report 132) for network relay points forming part of metropolitan/rural area networks which have implemented additional Listen-Before-Talk (LBT) and frequency/channel agility/adaptivity mitigation techniques and/or coordination in geographic areas of a high number of network relay points.
Note 2 Except if a procedure with the railway operator is employed (e.g. coordination or cognitive techniques) in order to avoid interference into occupied ER-GSM channels.
Note 3 DFS is required in the frequency range 5725-5850 MHz to ensure an appropriate protection to the radiolocation service (including frequency hopping radars), DAA is required in the frequency range 5855-5875 MHz for the protection of ITS, in the frequency range 5725-5875 MHz for the protection of BFWA, and in the frequency range 5795-5815 MHz for the protection of TTT applications.
Note 4 Transmissions only permitted within the frequency ranges 865.6-865.8 MHz, 866.2-866.4 MHz, 866.8-867.0 MHz and 867.4-867.6 MHz.
Note 5 Adaptive Power Control (APC) required, alternatively other mitigation techniques which achieve at least an equivalent level of spectrum compatibility.
Note 6 A network access point in a data network is a fixed terrestrial short range device that acts as a connection point for the other short range devices in the data network to service platforms located outside of that data network. The term data network refers to several short range devices, including the network access point, as network components and to the wireless connections between them.
Note 7 Network access points may be individually licensed, e.g. in geographical areas of a high number of network access points.
Note 8 This entry c2) will be reviewed in the near future, as appropriate, when the discussions at European Union level for the bands 870-876 MHz / 915-921 MHz are finalised, which will lead to closer alignment of c1) and c2).

Frequency issues
Sub-band c2): Use of all or part of sub-band d may be denied in some European countries that use all or part of these sub-bands for defence/governmental systems. In other countries that use sub-band 873-876 MHz for GSM for railways, extended band (ER-GSM), access to the part 873-876 MHz by non-specific SRD applications require implementing additional mitigation measures such as transmission timing limitations as set out in ECC Report 200. See Appendix 3 for national implementation concerning ER-GSM and defence/governmental services.
