1. An access point configurable to support concurrently a first wireless network having a first network name and a second wireless network having a second network name, the access point comprising:
- one or more antennae;
a radio coupled to said one or more antennae;
a memory to store an indication of a first delivery traffic indication message ‘
DTIM’
period value associated with said first network name and to store an indication of a second, different DTIM period value associated with said second network name; and
a processor, coupled to said radio and to said memory, to transmit via said radio a sequence of beacon frames at regular beacon intervals that are specified in said beacon frames, to include DTIMs for said first wireless network in a first subset of said sequence and to include DTIMs for said second wireless network in a second subset of said sequence,wherein said beacon frames specify said first DTIM period value, the interval between beacon frames in said first subset is the product of said first DTIM period value and said beacon interval, and the interval between beacon frames in said second subset is the product of said second DTIM period value and said beacon interval.

Abstract
A single access point may manage two or more wireless networks, each having a network name. The access point may be configured to store delivery traffic indication message (DTIM) period values on a per network name basis. A processor of the access point may manage, on a per network name basis, timing of transmission of delivery traffic indication messages.

7. A wireless system comprising:
-
a first wireless client device configurable to belong to a first wireless network having a first network name; a second wireless client device configurable to belong to a second wireless network having a second network name; and an access point configurable to transmit a second of beacon frames at regular beacon intervals that are specified in said beacon frames, to include delivery traffic indication messages for said first wireless network in a first subset of said sequence, and to include delivery traffic indication messages for said second wireless network in a second subset of said sequence, wherein said beacon frames specify a first delivery traffic indication message ‘
DTIM’
period value associated with said first network name, the interval between beacon frames in said first subset is the product of said beacon interval and said first DTIM period value, and the interval between beacon frames in said second subset is the product of said beacon interval and a second, different DTIM period value that is associated with said second network name. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method in an access point, the method comprising:
-
transmitting a sequence of beacon frames at regular beacon intervals that are specified in said beacon frames, wherein said beacon frames specify a first delivery traffic indication message ‘
DTIM’
period value;including delivery traffic indication messages for a first wireless network managed by said access point in a first subset of said sequence of beacon frames, wherein the first wireless network has a first network name and the interval between beacon frames in said first subset is the product of said first DTIM period value and said beacon interval; and including delivery traffic indication messages for a second wireless network managed by said access point in a second subset of said sequence of beacon frames, wherein the second wireless network has a second network name and the interval between beacon frames in said second subset is the product of a second, different, DTIM period value and said beacon interval. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
