Embodiment Construction

[0054] As shown in Figure 1, the device 1 comprises a DVB T / H tuner 2 and a WLAN transceiver 3, both of which are connected to a combined baseband device 4 comprising a WLAN as represented by WLAN+DVB-H software 5 protocol stack and DVB-H protocol stack.

[0055] The output of the DVB-T / H tuner 2 that derives baseband or low intermediate frequency (IF) signals is connected to a DSP (digital signal processor) 7 through an ADC (analog-to-digital converter) 6 .

[0056] Transmit input T of WLAN transceiver 3 X 8 is connected with DSP 7 through DAC (Digital-to-Analog Converter) 9 . In addition the receive output R of the WLAN transceiver 3 X 10 is connected with DSP 7 through ADC11.

[0057] DSP 7 is controlled by microcontroller 12 .

[0058] ADCs 6 and 11 , DAC 9 , DSP 7 and microcontroller 12 are arranged inside combined baseband device 4 . The combined baseband device 4 itself is connected to the main processor 13 .

[0059] FIG. 2 shows another embodiment in which the c...

Abstract

The invention relates to a method and a device for operation of two wireless services whereas a first service is broadcasting signals within burst with known time distances between the bursts and a second service is transmitting signals at least between a first partner and a second partner. The problem to be solved by the invention is to enable a user to use applications of at least to services concurrently at the same time with the same device. The problem is solved by an operation of one and the same device which is receiving bursts in a first mode of the first service and is switched from the first mode into a mode of the second service during the time between the bursts of the service.

Description

technical field [0001] The invention relates to a method for operating two wireless services, wherein a first service broadcasts signals in bursts of known time intervals, and a second service transmits signals at least between a first party and a second party . [0002] The invention also relates to a device for operating two radio services, wherein the first service broadcasts signals in bursts at known time intervals and the second service is transmitted at least between a first party and a second party Signal. Background technique [0003] Wireless Local Area Network (WLAN) devices are increasingly being deployed for new wireless infrastructures (eg, wireless Internet Service Points (ISPs)) in businesses, homes, and public places. The device complies with the recently ratified IEEE 802.11g standard, which is an extension (mainly on the physical layer) of the IEEE 802.11 standard. In addition to the so-called infrastructure mode, these devices also support an ad-hoc mo...
