Hi! we have 3 wifi spots installed with the following configuration:
AIR-AP1210 IOS AP, Cbus&MPCI slots EnetUplink
AIR-PWR-SPLY-CE AIR line cord central EU/Universal
S12W7K9-12302JA Cisco 1200 series IOS wireless LAN
AIR-ANT4941 2 x 2.4 GHZ, 2.2dBi dipole ant + RP-TNC connect
AIR-MP21G-E-K9 802.11g configurable radio module for AP
We want to add three more spots with exactly the same configuration to preserve homogeneity, however I have noticed that there is a AIR-MP21G-E-K9= module that supposedly upgrades AIR-MP21G-E-K9.
What is the difference and benefits of the upgrade? Should I buy SIX of those modules in order to upgrade the whole infrastructure?
