6 Doc:11-12-1083-01-00ah - Sensor Only BSS September 2012 Submission Sensor Networks vs. Offload Networks The 11ah targets sensor networks as well as offloading use case scenarios [1,2] The sensor traffic is very different from the offloading traffic Sensor traffic: –Requires low data rate –Low duty cycle (hours, days) –Utility operator managed Offload traffic: –High data rate –Bursty –Cellular operator managed (HS2.0) Huawei Technologies Inc.Slide 6

7 Doc:11-12-1083-01-00ah - Sensor Only BSS September 2012 Submission Sensor Only BSS The likelihood that large sensor networks coexists in the same BSS with the offloading traffic is low They are usually operated by different entities (utility companies versus cellular operators) Each type of traffic could require different BSS optimization, signaling and services –Offloading may require the implementation of HS2.0 features –Offloading may require the implementation of Lawful Intercept and Emergency Calls –Offloading may require the use of larger bandwidths 2MHz and above –Smart Grid and Sensor Networks may require “last gasp” signaling and high volume association after power loss –Sensor Networks will likely operate only in 1 or 2MHz bandwidth Huawei Technologies Inc.Slide 7

8 Doc:11-12-1083-01-00ah - Sensor Only BSS September 2012 Submission Sensor Only BSS Recently Marvell proposed the introduction of 11u/ HS2.0 features in the short beacon. These features are not necessary in the BSS serving sensors only, where can be additional overhead A separation between these modes of operation would offer specific framework for a better design Identifying what type devices are requesting the association cuts the unwanted overhead related to the probe request/response Huawei Technologies Inc.Slide 8

9 Doc:11-12-1083-01-00ah - Sensor Only BSS September 2012 Submission Sensor Only BSS We propose that a BSS would have three dedicated modes of operation either to allow only sensor traffic or to allow both sensors and offloading or only offloading devices A STA could declare in the Probe Request message or at the association as Sensor Device Only, Offloading Device Only or Mixed Mode Device A beacon could carry 2 bits that signal that the BSS accepts Sensor Only Devices, Offloading Only Devices, or Mixed Mode devices Some potential benefits: –The beacons sequence (short long) could have different periodicity in Sensor Only BSS –The Probe Response can be done based on device’s type that sent a Probe Request –The offload devices would not try to associate with AP in Sensor Only reducing the overhead Huawei Technologies Inc.Slide 9

10 Doc:11-12-1083-01-00ah - Sensor Only BSS September 2012 Submission Sensor Only BSS High performance AP that supports very large number of sensors and smart meters will be configured Sensor Only When lower performance devices are required such as 11ah for AP for home deployment Mixed Mode will be marked as true Some private stores, for instance Starbucks, could have Offloading Only BSS for their customers Huawei Technologies Inc.Slide 10
