Research paper on validation of new WLAN protocol for M2M communication accepted to the 6th MACOM International Workshop

1 October 2013

A new research paper on new a new WLAN protocol for M2M (machine-to-machine) communication has been accepted to be presented at the 6th Multiple Access Communication (MACOM) International Workshop.

The paper, entitled "Capacity Analysis of IEEE 802.11ah WLANs for M2M Communications" was written by Antonio Adame, Dr. Albert Bel, Dr. Jaume Barcelo, Javier Gonzalez and Dr. Miquel Oliver".

"Focusing on the increasing market of the sensors and actuators networks, the IEEE 802.11ah Task Group is currently working on the standardization of a new amendment. This new amendment will operate at the sub-1GHz band, ensure transmission ranges up to 1 Km, data rates above 100 kbps and very low power operation.

With IEEE 802.11ah, the WLANs will offer a solution for applications such as smart metering, plan automation, eHealth or surveillance. Moreover, thanks to a hierarchical signalling, the IEEE 802.11ah will be able to manage a higher number of stations (STAs) and improve the 802.11 Power Saving Mechanisms. In order to support a high number of STAs, two different signalling modes are proposed, TIM and Non-TIM Offset.

In this paper we present a theoretical model to predict the maximum number of STAs supported by both modes depending on the traffic load and the data rate used. Moreover, the IEEE 802.11ah performance and energy consumption for both signalling modes and for different traffic patterns and data rates is evaluated. Results show that both modes achieve similar Packet Delivery Ratio values but the energy consumed with the TIM Offset is, in average, 11.7% lower."

Given the promising results obtained, the application of this technology to markets like eHealth and Smart Metering can be of high interest for the group and companies related.
