Embodiment Construction

[0014] Referring to the drawings, wherein like reference numerals refer to like elements, the techniques of the present disclosure are illustrated as being practiced in appropriate environments. The following descriptions are based on claimed embodiments and should not be construed as limitations on the claims referring to alternative embodiments not expressly described in the text.

[0015] Briefly, in particular embodiments, a Wi-Fi router receives multiple connection requests from multiple gas or electric utility meters. In response, the Wi-Fi router transmits a unique identifier to each meter. Because wireless meters are typically battery powered and cycle in and out of sleep mode, the Wi-Fi router buffers data from the utility company for wireless meters (eg, firmware updates). If the number of meters with buffered data at the Wi-Fi router is relatively low, the Wi-Fi router transmits a list of unambiguous meter identifiers to indicate that buffered data is maintained fo...

Abstract

Disclosed are methods for delivering data (212) to a wireless station (102). An access point (104), or any other suitable device or system, receives a plurality of association requests (204) from a plurality of wireless stations (102) and transmits a different association identifier (208) to each of the plurality of wireless stations (102). The access point (104) buffers data (212) for a subset of the wireless stations (102). If the number of wireless stations (102) with buffered data (212) at the access point (104) is less than a threshold, then the access point (104) transmits a list of association identifiers indicating that buffered data (212) are held for each wireless station (102) identified by the list. If the number of wireless stations (102) with buffered data (212) at the access point (104) is not less than the threshold, then the access point (104) transmits data indicative of a range of association identifiers indicating that buffered data (212) are held for at least one wireless station (102) identified by the range.

Description

technical field [0001] The present disclosure relates generally to wireless signals and, more particularly, to communicating data to wireless stations. Background technique [0002] Wireless sensors are used in a variety of applications such as reading gas meters, monitoring temperature, etc. These wireless sensors are often placed in locations where they cannot be plugged into a wired power source and, therefore, must rely on battery power for extended periods of time. To conserve battery power, these devices typically enter a low-power mode during measurements and communications. Contents of the invention [0003] Typically, these wireless sensors communicate with the application server via an access point (eg, a Wi-Fi router). Access points are devices that allow wireless devices such as wireless sensors to connect to a limited network such as the Internet. Typically, each time an application server sends data to a wireless sensor, the data is first buffered by the a...
