Is AD6LoWPAN implementation standards based solution?

Yes. AD6LoWPAN is a standards based solution and should be able to connect with other off-the-shelf 6LoWPAN devices. 

The 6LoWPAN protocol conformance of AD6LoWPAN solution has been verified using ETSI TTCN Test suite. The target RFCs for this test suite are :

• RFC 4944 Transmission of IPv6 over IEEE 802.15.4
• RFC 6282 Header compression for 6lowpan
•

There are a few other aspects that need to be looked in to before trying to interconnect any off-the-shelf 6LoWPAN devices with this ADuCRF101 based AD6LoWPAN solution:

1. The devices shall support IEEE 802.15.4 MR-FSK PHY in the Sub-GHz frequency bands.
2. The version of IEEE802.15.4 MAC: AD6LoWPAN employs IEEE802.15.4 (2006) MAC data & ACK frames only.

Analog Devices is in the process of identifying a few off-the-shelf 6LoWPAN devices that meet these requirements and carry out interoperability testing with those devices. The device list shall be published at right after the interoperability tests are complete.
