Misc. Questions and Answers

A.Generally speaking the AP 2600e or 3600e would be my first choice as these external antenna models have the highest operating temperature range -20 to 55C. The AP 1600 can also be used but has a slightly lower operating temperature -20 to 50C. If temperature is not a concern then the internal antenna “I” series 1600, 2600 and 3600 may be used.

Q.What if I am in a country where the regulatory agency may not approve the AP to be used outdoors because of UNII-1 band restrictions or I wish to use higher gain antennas?

A.Consider deploying the Cisco Mesh products (1550 series) or look for Access Points ending in “P” for professional install, such as the 3502P series or our outdoor bridging products.

Q.Which AP is best for high density deployments?

A.Both the 2600 and 3600 have virtually identical AP density for coverage based design. Capacity-based designed (smaller-cells) will yield a slightly higher average cell capacity with the 3600 using 3-spatial stream devices and of course an even higher density when using the optional 802.11ac module.

Q.Cisco has a newer Power Injector (AIR-PWR-INJ5) how is this different from the (AIR-PWR-INJ4)?

A.The newer AIR-PWR-INJ5 is a low cost injector for use with the AP 1600 and AP 2600 Series Products. It is an 802.3af (15.4W injector) the AIR-PWR-INJ4 is a more power injector designed to work with the AP 3600 when optional modules are used. The AIR-PWR-INJ5 can be used with the AP 3600 but not if the optional module is used.

Q.Can industrial wireless motion or smoke detectors cause WLAN interference?

A.Yes, some products like United Technologies DD475 and Optex MX-50 operate in the 2.4 GHz band as do other wireless “chimes”, cameras and other industrial equipment from other manufacturers.

Q.How much power in Watts does the AP 3600 draw when an option module is used?

A.18 Watts – AP 3600 draws slightly more than 802.3af (15.4W) with the module installed. Powering options include 802.3at PoE+, local Power Supply AIR-PWR-B or injector AIR-PWR-INJ4. If performing Surveys or 2.4 GHz support is not needed, that radio may be disabled allowing the module to have full power and functionality using 802.3af (15.4 Watts)

Q.What is the Ethernet requirement for 802.11ac (Wave-1)?

A.A single GbE cable is fine for Wave-1. While it is true 802.11ac (Wave-2) will exceed GbE speeds, there is no need or requirement for cabling greater then GbE for 802.11ac Wave-1. Installers wishing to future proof new installations should consider pulling CAT-6a cables <at least 1> and either another CAT6a or a CAT5e cable (this allows you to fall back to 2 GbE ports) for some iterations of Wave-2 and/or support 10GbE should this emerge as the method. 10GbE has some challenges such as PoE standardization – Again for the foreseeable future a single GbE is all that is needed.

Q.Is it true that 802.11ac is coming in “waves” and that new hardware is required for each “wave”?

A.The first iteration of 802.11ac (Wave-1) is available today, and both Wave-1 and Wave-2 requires new hardware to take advantage of the new features in each “wave” or iteration. Fortunately, with a modular AP approach like the AP 3600, upgrading to Wave-1 today is easy. Also unlike the competition, both the AP 3600 and newer Cisco Access Points in the future with modular support will make upgrading to Wave-2 a painless process without having to perform a complete rip and replace.

Q.With the 802.11ac Module installed in the AP3600, will all 3 radios be active?
