AIR-ANT1728 Antenna

[Francis Jr Asis]

Anybody from you guys can help me. What is the maximum distance or safe distance this antenna can cover. I am using Aironet2602E access point. Because i couldnt understand the radiation pattern. There is 5 circle in the Radiation pattern but i dont know how to convert this is distance. Its only showing the DB.

Would you please tell me is there some advantage for warehouse enviroment with 3602e compare with 3602i

Forgive me for saying this, but 3600 for a warehouse environment is a bit of an over-kill.  For a warehouse floor, I would prefer to use 2600i/e.  The reason is the throughput of the 3600 (without the 802.11ac or the 3G pico cell module attached) is best suited for large, high speed volume traffic.  Warehouse wouldn't push that far.

Ok, back to your question:  When would I use 2602e over 2602i?

Height of the shelves/racks is one of the things I'd look for.  If the racks are higher than, say, 10 feet, omni directional patch antennas are not going to work because you may not be able to get adequate coverage if you hit the shadows of the antennas.  This is where APs with internal antennas come in because of the signal footprints go along the shelves but they also go up and down the height of the shelves.

EDIT:  Forgot to mention that I'd also prefer 2602 over 3602 for warehouse because of the cost.  My philosophy:

1.  3600 for warehouse floor:  No

2.  2600 for warehouse floor:  Yes

3.  1600 for warehouse floor: 

4.  3500 for warehouse floor:  2600 instead (more throughput plus 2600 is cheaper)

Warehouse office:

1.  First Preference:  3600

2.  Second Preference:  2600

3.  Third Preference due to cost:   700

Great explaination Leo!

Wow what a great weekend read:) Sir Leo is correct on his explanations. So I guess I will put in my 2 cents. I have done a recent warehouse using the AIR-ANT2544V4M-R= with 3602e's. the 3602e's was the customer standard and would work the same for the 2602e's. Now I had these up on about 12 meters and had no issue at all. Now understand what Leo mentioned earlier because its important. You need to match the TX power (EIRP) from the client and the AP to get you the best result. If you don't, we'll it may still work, but you have to understand that whatever signal you see from your client to the AP isn't what the AP sees from the client. Using these single antennas with 4 leads is really the best way to go. You don't have to worry about how far each antenna should be separated and having to deal with mounting 4 seperate antennas. Like Sir Leo mentioned, the days of a single antenna is long gone and its due to having to keep up with the wireless technology. Diversity in a warehouse or really any environment is almost required unless your in an open field with nothing around.

Never look at, well this is what the client wants:) look at what needs to be done to make the wireless work well. If you listen to your customer and use a single antenna, well what happens if they have issues. It's easy when they have an autonomous setup, but things change very fast when you go from autonomous to lightweight.

Consider i will use the 3620e AP what is the best L2 switch i could use?2960 is enough for this? The core switch WS-C3750X-12S-S

Any switch that is gigabit and supplies 802.af unless you put a module in. Then you need the switch with enhanced PoE. I doubt you will need to add a module in it for the warehouse but just in case, you know what you need.

Core switch of 3750X-12S is good because this means you can position your switch to be in the centre of the location of the APs.

I'd rather use 2960S instead of plain 2960 PoE.  The reason why I'd prefer 2960S is the potential to use 20.0w PoE instead of 15.4w PoE.

You may also want to invest in running multiple fibre optic from the core to the location of the 2960S.  This way, you can configure multiple fibre optic ports into Etherchannel.  This takes care of potential bottleneck (not that you'll be seeing them) and redundancy.

If you are not sure, post the model of the 2960 or 2960S you need, the SFP/SFP+ module your client approves of and we'll give you some feedbacks.

Another thing.  The maximum cable distance from the AP to the switch to do both GigabitEthernet and PoE is 100 metres.

[Francis Jr Asis]

I attached the switch connection from core to layer 2.

Layer 2 i use 2690S-48LPS-L.

Maybe u guys have template configuration for this switches. I would be very happy.

[Leo Laohoo]

1.  What's the AP1600 for?

2.  You've got 6-7 APs per switch and nothing else.  If this is correct, you may want to consider looking at some 8-port switches, like the WS-C3560CG-8PC-S.

3.  I presume you've factored in the SFP modules for the switches and WLC.

Thanks, SIR Scott.  Good points.  Endorsed!

Hi

will  AIR-ANT1728 will be supported on cisco 1220B access point ?

Thanks & Regards

[Scott Fella]

Any antenna that has the correct antenna connector and is made for that radio will work. The antenna you stated has an rp-tnc connector which your ap also has and is also designed for the 2.4ghz which your ap has. So yes that will work.
