Wireless Networking Technology Speeds Automotive Testing

Engineers at Standard Motors are the to start with to use backhaul technological know-how created at Cisco to carry out pre-manufacturing functionality testing on motor vehicles. The wireless, Wi-Fi-centered technologies lets car engineers keep track of numerous hundred info channels concurrently in real time through examination operates to keep an eye on auto operational parameters and modify the take a look at as it is remaining carried out (if essential).

Pre-generation motor vehicles are crafted specially for validation testing to assure autos or vehicles complete as meant. During this improvement stage tremendous volumes of performance info from a extensive range of checks are collected. These final results are then used to refine the pre-production cars before they are created and marketed to people.

Without the need of backhaul, data has been gathered facts on “black boxes” and could not be analyzed until just after the full check was operate there was no way to review information for the duration of a test or changes the check on the fly. So, if there were being challenges with a car method or exam parameters that would render a test unusable, absolutely nothing could be done right up until the data was checked at an offsite lab just after the check. Then the 30- to 60-moment exam may have to be recurring, which wastes time and resources. Backhaul lets engineers discover any problems with the car or check parameters in the course of the take a look at procedure and solve them in genuine time.

Applying before wi-fi networks to accumulate this pre-generation details did not do the job reliably both owing to the speeds the check autos were being travelling, which generally exceeded 100 mph.

To overcome these complications, backhaul combines the trustworthiness and speed of fiber connectivity with the versatility of wireless communications. It provides up to 500 Mbps. It characteristics extremely-low latencies, large-bandwidths, seamless handoffs with zero packet losses and private cell connectivity for mission-vital programs. It allows carmakers and other companies lengthen their networks wirelessly.

While backhaul is dependent on Wi-Fi, it is not an entry engineering. It can hook up relocating belongings these kinds of as automobiles, AVG, cranes, tele-distant motor vehicle and trains, or increase networks when jogging fiber isn’t possible or is much too pricey. It is also more reliable on wireless networks that include parts susceptible to developing interference this kind of as ports and warehouses, where stacks of containers or pallets can produce dead zones.

At GM, backhaul is supplying check engineers instant accessibility to data, allowing them be more actively concerned and make true-time decisions for the duration of examination runs to eliminate the need to have to re-operate a take a look at. This streamlines the screening system and will save time.

“Since deploying Cisco wireless backhaul at the functionality tracks of our Milford Proving Floor, GM now has stable and secure wi-fi network connections in that atmosphere exactly where vehicle speeds that can exceed 100 mph,” claims Stephen Jenkins, director, World-wide Labs, Proving Grounds Functions & Materials Engineering. “This connectivity lets us accomplish serious-time analysis and stream data straight into our Organization Information Middle without the need of buffering or human intervention.”

“GM desired a experienced solution to gain true-time visibility into car or truck exam details, and they analyzed many systems which all fell brief,” claimed Michael Shannon, VP of engineering, Cisco IoT. “Since deploying backhaul, even so, GM has shortened the engineering cycles and ultimately assisted enhance time-to-market place for technological innovations.”
