I wanted to compare the throughput of Cisco 2802i and Cisco 3802i access points so that I can get some realistic stats on their performance.
Below report from Miercom is a good reference.
Below are the comparison charts for these 2 access points.
Test switches : Cisco Mig 3850 switch and Cisco 3850 U-poe switches
Access Points: Cisco 2802i and Cisco 3802i
Client Device: Mac book pro with 3 Spatial stream
Test scenario 1: Connected the Cisco 3802i access point into the MGig switch
Test scenario 2: Connected the Cisco 2802i access point into a 1Gig uplink switch
Below are the results for 160 MHz, 80 MHz, 40 MHz and 20 MHz respectively.
Results:
On 160 MHz : The 3802i showed better results than 2802i but practically this bandwidth is not useable unless we just have one access point in that vicinity on 5 GHz radio.
On 80 MHz Channel: 2802i showed better consistent performance with data transfer touching 1 Gig.
3802i managed to touch 800 Mbps on this bandwidth.
On 40 MHz Channel: 2802i showed better consistent performance with data transfer peaking at 900 Mbps and around 800 Mbps average
3802i managed to touch 700 Mbps and was around 600 Mbps average.
On 20 MHz Channel: 2802i showed better consistent performance with data transfer peaking and maintaining its transfer at 600 Mbps and 3802i touched 600 Mbps and was inconsistent with around 400 Mbps average.
Test method: Transfer huge files between a Mac connected to Wireless network to a remote server on wired network.
Next tests: Perform this throughput using IXIA on same switch platform to eliminate any hardware issues.
