Choosing the Right Access Point 
Models
The Cisco 3700 Series Access Point (AP 3700) targets customers requiring support for mission-critical 
applications. The AP 3700 embodies ClientLink 3.0, an innovative antenna technology comprising four 
transmit radios and four receive radios called 4X4 in a Multiple Input Multiple Output (MIMO) 
configuration supporting 3 spatial streams (3SS) together referenced as 4x4:3. Using this type of antenna 
system along with additional Modulation Coding Schemes (MCS rates supporting up to 256 QAM) and 
80 MHz channel bonding, rates of up to 1.3 Gbps can be supported.
ClientLink 3.0–using these features along with an additional antenna (N+1)–allows for beam-forming 
for all 802.11a/g/n clients (like ClientLink 2.0) and now beamforms to 11ac 3 spatial streams clients.
Figure 1 Access Point Portfolio Placement
Access Points are available in three models:
• Internal antennas version labeled “i” have captured antennas (part of the housing and not 
removable). The “i” series is designed for indoor Enterprise installations where office aesthetics are 
a primary concern.
• External antennas version labeled “e” are more rugged and designed for industrial use in locations, 
such as hospitals, factories, warehouses, and anywhere a need exists for external antennas and/or 
extended operating temperatures. The “e” version also supports mounting inside NEMA enclosures 
for use in the most demanding environments.
• Access Points for Professional Installations are labeled “p” series and may be used in outdoor 
applications.
