Chapter 2 AP121 and AP141 Platforms
The AP121and AP141 wireless access points are designed for excellent throughput and range. They provide
dual concurrent 802.11b/g/n and 802.11a/n radios for 2x2 MIMO (Multiple Input Multiple Output) antenna
configurations. When you enable 802.11n high-throughput options such as wide-channel mode (40-MHz
channels), A-MPDU and A-MSDU packet aggregation, short guard interval, and MCS15 data rates, they can
provide a PHY data rate up to 300 Mbps per radio. The AP121 has four internal antennas, and the AP141 has
four detachable external antennas (two 2.4 GHz and two 5 GHz in both cases). Both models have an RJ45
10/100/1000 Ethernet port, an RJ45 console port, and a USB modem port (reserved for future use).
