Comtrend PG-9172 Powerline Adapter Review: G.hn Gets Primed for Retail Pushby Ganesh T S on May 3, 2016 8:30 AM EST
HomePlug and G.hn Go Head to Head
This section presents the benchmark numbers obtained for the four different test cases outlined in the previous section. The Comtrend PG-9172 numbers are graphed in red, while the ZyXEL PLA5405 (representing HomePlug AV2 with MIMO support) numbers are in blue. The main tussle is between these two adapters - they are close in price (USD 77 vs. USD 83) and represent the best possible implementations of the two standards in the evaluated set.
Performance Metrics - TCP Downlink and Uplink
Node A represents the shortest physical distance between the tested nodes. This is a close fight between the HomePlug AV2 and G.hn adapters, with the PG-9172 coming out with a slight lead. Surprisingly, the ZyXEL PLA5206 SISO adapter is better than the PLA5405 in this scenario.
Node B is the garage outlet across the AFCI circuit breaker. The SISO adapter is the surprise winner here, though the G.hn PG-9172 comes a close second. The PLA5405 comes in third, quite a bit behind the G.hn adapter.
Node C is in the same wall as the garage outlet, and across the circuit breaker again. Here, the Comtrend adapter performs quite well, though it is really hard to choose between the HomePlug AV2 adapters and the G.hn adapter given the small differences in the bandwidth numbers.
Node D is one of the farther outlets from the master node, and the Comtrend PG-9172 adapter establishes a clear and sizable lead over the HPAV2 adapters.
Node E is in the adjacent room, and is one of the closer adapters (similar to Node A). The performance ordering is also similar.
The Comtrend PG-9172 emerges as the clear winner in Node F.
Performance Metrics - UDP Downlink and Uplink
The UDP results across all the nodes are similar in ordering to the TCP results.
The above results show that the Comtrend PG-9172 G.hn adapter has the best performance in almost all of the tested scenarios.
