What is claimed is:
1. A gas conducting system which includes a filter for removing moisture from a gas passed therethrough, wherein said filter is provided with a desiccant arranged in a filter housing structure having an inlet and an outlet for the gas to flow through, and wherein the housing structure is provided with a seal which seals the housing relative to the surrounding environment of the gas conducting system, said seal comprising at least one weakened area with a lower pressure limit for failure than the rest of the seal.
2. A gas conducting system according to claim 1, wherein the moisture removing filter is a disposable filter in which the desiccant cannot be replaced.
3. A gas conducting system according to claim 1, wherein the housing structure of the filter can be opened and the desiccant can be replaced.
4. A gas conducting system according to claim 1, wherein the weakened area of the seal is formed by a reduced cross section compared to the rest of the seal.
5. A gas conducting system according to claim 1, wherein the seal with the weakened area is provided between the filter housing structure and a mounting location for the filter on the gas conducting system.
6. A gas conducting system according to claim 5, wherein the seal is fixed in a recess at the mounting location.
7. A gas conducting system according to claim 1, wherein the seal with the weakened area is provided between two housing parts of the filter housing structure.
8. A gas conducting system according to claim 1, wherein the seal with the weakened area is made of a material that has substantially constant sealing properties within an operating temperature range specified for the gas conducting system.
9. A gas conducting system according to claim 1, wherein said gas conducting system is a compressed air brake system of a motor vehicle.
10. A moisture removing filter comprising a desiccant arranged in a housing structure, said filter having a seal for sealing the housing structure relative to the surrounding environment of the housing structure, wherein said seal comprises at least one weakened area with a lower pressure limit for failure than the rest of the seal.
11. A filter according to claim 10, wherein the filter housing has an inlet and an outlet for connection to a gas conducting system.

17. A method in an access point (AP), the method comprising:
determining an expected data rate for communications over a link between the access point and a mobile station and an actual data rate of communications over the link, wherein the expected data rate is based on radio frequency power levels of signals received at the mobile station over the link; and
in response to determining the expected data rate, determining a measure of a quality of a link between the access point and a mobile station.
18. The method of claim 17, further comprising determining whether to trigger the mobile station to initiate a handoff from the access point based, at least in part, on the measure of the quality of the link.
19. The method of claim 18, further comprising selecting a different access point as a target of the handoff based on a determination that a link with the different access point experiences less interference than the link between the mobile station and the access point.
20. The method of claim 17, further comprising determining based, at least in part, on the measure of the quality of the link whether to transfer to the link a communication session currently being carried over a different link between the mobile station and the access point.
21. The method of claim 17, further comprising using signal strength measurements of the signals as an indication of the power levels.
22. The method of claim 17, further comprising using received channel power indicator measurements of the signals as an indication of the power levels.
23. The method of claim 17, further comprising selecting a network based, at least in part, on the measure of the quality of the link.
24. A mobile station comprising:
a wireless local area network communication interface through which the mobile station is able to communicate with an access point over a communication link; and
one or more processors coupled to the wireless local area network communication interface and configured to:
determine an expected data rate for communications over a link between the access point and a mobile station and an actual data rate of communications over the link, wherein the expected data rate is based on radio frequency power levels of signals received at the mobile station over the link; and
determine a measure of a quality of a link between the access point and a mobile station by comparing the expected data rate to the actual data rate.
25. The mobile station of claim 24, the one or more processors further configured to determine whether to trigger the mobile station to initiate a handoff from the access point based, at least in part, on the measure of the quality of the link.
26. The mobile station of claim 25, the one or more processors further configured to select a different access point as a target of the handoff based on a determination that a link with the different access point experiences less interference than the link between the mobile station and the access point.
27. The mobile station of claim 24, the one or more processors further configured to determine based, at least in part, on the measure of the quality of the link whether to transfer to the link a communication session currently being carried over a different link between the mobile station and the access point.
28. The mobile station of claim 24, the one or more processors further configured to use signal strength measurements of the signals as an indication of the power levels.
29. The mobile station of claim 24, the one or more processors further configured to use received channel power indicator measurements of the signals as an indication of the power levels.
30. The mobile station of claim 24, the one or more processors further configured to select a network based, at least in part, on the measure of the quality of the link.
31. A non-transitory computer readable medium storing instructions to cause a processor to perform operations comprising:
determining an expected data rate for communications over a link between the access point and a mobile station and an actual data rate of communications over the link, wherein the expected data rate is based on radio frequency power levels of signals received at the mobile station over the link; and
in response to determining the expected data rate, determining a measure of a quality of a link between the access point and a mobile station.
32. The computer readable medium of claim 31, the instructions further comprising determining whether to trigger the mobile station to initiate a handoff from the access point based, at least in part, on the measure of the quality of the link.
33. The computer readable medium of claim 32, the instructions further comprising selecting a different access point as a target of the handoff based on a determination that a link with the different access point experiences less interference than the link between the mobile station and the access point.
34. The computer readable medium of claim 31, the instructions further comprising determining based, at least in part, on the measure of the quality of the link whether to transfer to the link a communication session currently being carried over a different link between the mobile station and the access point.
