Mevo Plus has been re-engineered for faster and stronger performance. Upgrades include newly introduced 802.11ac Wi-Fi chip for increased range and dual 2X2 MIMO antennas for stronger connection strengths in noisy environments. Mevo Plus can stay connected to your mobile device from over 100 feet away, more than five times the range of the 1st generation Mevo. There is one easy way to tell the difference and that's the front grill. Mevo Plus has a grey front audio grill while Mevo Gen 1 has a red audio grill.
