Business driver

There is currently no global specification for broad IoT interoperability, independent of the physical radio.   A DQ firmware upgrade would introduce a universal lower MAC, allowing for synchronous and asynchronous flows to share the channel. DQ in place of ALOHA has also proven a seamless migration path for legacy devices.  Eliminating the ALOHA problem is also the key to stable QoS under any condition, and will make possible regional mesh networks as distributed public utilities for broadband and the IoT.

Business use cases

1. Automotive

2. Industrial IoT

3. Smart City

4. Wireless Optical Mesh

5. Eliminate backhaul or aggregation bottlenecks

6. Save power by half

7. Fix security by eliminating the middle hardware buffer

Business Cost - Initial Build Cost Target Objective

There is no additional cost for utilizing a Distributed Queue (DQ) collision detection scheme, as it is a direct replacement or swap with Aloha-based technologies including Ethernet or any other IEEE 802.x.x and requiring no change at OSI layers 2.5 or above.  50% energy savings in the PHY since retransmission of payload data is eliminated.

Experimental Zigbee and LoRa base stations (RasPi and a radio hat) were built for $85 at Bucknell, improving the number of competing devices from 1500 to 5700 and concluding that crowdsourced regional mesh networks where hotspots link directly with each other for a network that gets stronger as it gets larger.

Business Cost – Target Operational Objective

The target operational objective is to achieve >95% throughput at all times, or Near-Perfect packet efficiency in a star network.  Some efficiency will be lost in the hybrid DQ model to afford a commercial migration path for legacy devices which have no knowledge of the novel MAC, but this will still shatter the Aloha-based 50% theoretical maximum.

Security need

Security is a function of packet efficiency.  A broadcast Lower Layer 2 architecture for ensembles will open the IoT metaverse, including channel/state information cross layered among the various OSI layers.  DQ also allows us to encrypt the whole packet at the MAC/Data Link layer including the packet header and subheader with new variable fields for 9 levels of priority queuing, format information. or other to be determined fields.  See security discussion in the attached SAE Journal article.

Regulations

CPNI law is a better part of the Telecommunications Act of 1996 which should be upheld in shared-packet networks if it were only possible in ALOHA or CSMA networks like Ethernet.  Also bearing consideration should be the restoration of telecommunications privacy laws which began at the US Postal Service before transferring to telecom sector under the FCC.  Finally, a push toward broadcast media in the digital world should bolster media ethics laws that existed under old TV.

Other restrictions

Licensed RF is restricted.  WiFi, and other unlicensed RF for the IoT including long range TV White Space airwaves are not.  Therefore, future distributed public utilities should use TVWS for long range connectivity mixed with metro meshes.  Another restriction is the long term decision for AT&T to reduce its copper footprint by half, when the Central Office could also get the DQ firmware upgrade for perfectly good copper to be useful, and reducing EMF pollution dramatically.
