For a standard in the IEEE 802 family to be approved, a ‘Coexistence Assurance’ document must be provided and approved. The coexistence approval process usually involves IEEE members working together to ensure that all 802 wireless standards can coexist in the same space at the same time. In this document, coexistence for the 802.15.10 recommended practice is reviewed and addressed.

Parameters Which Affect Coexistence

All of the wireless system parameters that affect performance (such as modulation scheme, error correction, spread spectrum, frequency hopping rate, traffic character, packet size, offered load, transmission power, and network topology) can be divided into two types: (1) parameters that affect only the performance of the system where they are implemented; (2) parameters that affect the interactions between the interferer and the victim systems. It is apparent that all of parameters belonging to the second type are PHY parameters.

As recognized in the previous paragraph, only PHY layer parameters affect interference to other systems and also performance degradation of a device by other systems (or devices) can be evaluated only with the PHY layer parameters.

802.15.10 Coexistence

The TG10 recommended practice for Layer 2 routing does not specify or affect to any PHY features and parameters. That means it does not involve any modifications of existing PHYs. Therefore in the 802.15.10 practice, coexistence issues do not need to be addressed.

As an example, a discussion of the coexistence of the various IEEE 802.15.4 PHYs with other wireless systems is given in “Coexistence analysis of IEEE Std 802.15.4 with other IEEE standards and proposed standards", which involves only PHY parameters. This discussion covers all coexistence issues for 802.15.4.

As a conclusion, 802.15.10 does not intend to modify any existing PHYs or propose a new PHY. As a result, additional discussion of the coexistence for this practice is not necessary.
