"Tri band" is like having 3 Access Points in one box, on serving the 2.4GHz waveband, (usually) two serving the 5GHz using different radio frequencies. The advantage is that all those AP's can transmit/receive concurrently with each other which mitigates the "only one thing at a time can transmit" paradigm of Wi-Fi.
It's just the same as if you bought 3 physical AP's, co-located them and took some care about how you tuned the radio channels they used.
Therefore, whether it's "worth it" is a value judgement based on how many client devices you have, how much data they need to transmit, how much they are currently competing with each other for "air time" and whether you can distribute your clients between the AP's. |
