         2 . The display and/or operating module according to  claim 1 , wherein the first radio interface and the second radio interface use different frequency bands. 
     
     
         3 . The display and/or operating module  claim 1 , wherein the first radio interface and the second radio interface have different data rates. 
     
     
         4 . The display and/or operating module according to  claim 1 , wherein the first radio interface is configured for communication with a first higher-level unit and the second radio interface for communication with a second higher-level unit, wherein the first and the second higher-level unit perform different functions. 
     
     
         5 . The display and/or operating module according to  claim 1 , wherein the different radio interfaces form parallel data paths, in particular, that the first radio interface forms a first data path and the second radio interface forms a second data path. 
     
     
         6 . The display and/or operating module according to  claim 5 , wherein the different radio interfaces have different access rights and/or authorizations and/or a different availability. 
     
     
         7 . The display and/or operating module according to  claim 1 , wherein the display and/or operating module has its own energy supply unit in the form of an energy storage unit and/or energy harvesting module. 
     
     
         8 . The display and/or operating module according to  claim 1 , wherein at least one of the radio interfaces, has an antenna adapter for connecting at least one external antenna. 
     
     
         9 . The display and/or operating module according to  claim 1 , wherein the display and/or operating module has a power management unit that activates and/or deactivates the radio modules in a time-controlled and/or event-controlled manner. 
     
     
         10 . The display and/or operating module according to any one of the preceding  claim 1 , wherein it is configured as a retrofittable replacement module for an existing field device. 
     
     
         11 . A field device with a modular configuration, with a display and/or operating module according to  claim 1  the. 
     
     
         12 . A field device with a modular configuration according to  claim 11 , wherein the field device and the display and/or operating module are completely supplied with energy via a two-wire interface of the field device. 
     
     
         13 . A field device with a modular configuration according to  claim 11 , wherein the two-wire interface is configured in accordance with the 4 mA to 20 mA standard or as a two-wire Ethernet interface, in particular as an Ethernet APL interface, and the field device is preferably configured to be intrinsically safe. 
     
     
         14 . A method for retrofitting an existing field device comprising installing in said existing field device a display and/or operating module comprising: a housing, a display unit arranged in the housing and an electronics unit, wherein the display and/or operating module has at least one mechanical interface for connecting the display and/or operating module to the field device and a data interface for a communication between the display and/or operating module and an electronics module of the field device, wherein the electronics unit has at least one first radio interface and at least one further second radio interface different from the first radio interface.
