What's the area coverage and devices support for Cisco AP 2602

Hi Guys,

What's the area coverage of Cisco AP 2602  and also how many devices it support?

What's the area coverage of Cisco AP 2602  and also how many devices it support?

Depends on whether or your AP has internal antenna or you are using an external antenna.

Rule-of-thumb:  25 wireless clients per AP. 

This rule-of-thumb can vary as well depending of the type of wireless traffic.  If you have just plain email, web then you could potentially look at a higher number of 35.  If you are talking about HD video streaming then you are looking at 5 to 8 wireless clients.

The number gets impacted with the speed of your uplink.  If you have 100 Mbps uplink from the AP to switch, then number drops.  Significantly.

Will use external AP "AIR-SAP2602E-x-K9"

Will use external AP "AIR-SAP2602E-x-K9"

And what antenna are you using?

Really, Can't get this information but I think other brands mentioned this info as default like area / devices

Some companies, like Cisco, doesn't like to advertise because it's common sense.  The range or distance covered by AP is totally dependent with  your environment, the way the AP is installed, channel interference from nearby wireless, data rates used, weather pattern, etc.  You want to try putting that on a document that other people can understand before they fall asleep?

You want to know the EXACT range?  Get a wireless site survey done.

The antenna will be as the following

AIR-AP-BRACKET-1	802.11n AP Low Profile Mounting   Bracket (Default)
AIR-AP-T-RAIL-R	Ceiling Grid Clip for Aironet   APs - Recessed Mount (Default)
AIR-ANT2535SDW-R	2.4 GHz 3dBi/5 GHz 5dBi Low   Profile Antenna White RP-TNC

I agreed with you totally but there are no any concepts can determine that at least the number of devices ?

The device max would be 256, but you can't look at that. You have to take into account the bandwidth required per user and then look at your over subscription ratio from your connection the AP/Switch port.

Coverage is also dictated by attenuation in the area surrounding the AP. In an open area, you might get good coverage out to 300 feet, but is that the signal you require.

This would be the same with other vendors... The max they might say doesn't mean it will work as expected. It's marketing:)

AIR-ANT2535SDW-R

Seriously?  You want to install this? 

Wow.  Sure way to waste money.

This antenna has the same, if not similar, transmit power values as the 2600I.

The site consider is open area 500meter about devices need cover over 150 devices
plus with external controller and external antenna

Get a wireless site survey done.

Another important thing:  People think that if they install an antenna, a high gain antenna, to their AP they can "boost" the signal and they can get more throughput, range, etc. 

This is a falacy and can be no further from the truth.  Let's use a little bit of logic here:  Let's say you stick a -12 dBm antenna to your AP.  Ok, you boost the distance coverage.  However, what is the strength of the antenna of the wireless client?  And why is THIS very important? 

Because if your wireless client can hear you even from halfway out the range, do you think the AP can hear the return signal when the wireless clients' antenna is very small?  The AP won't.  Wireless is a two-way street.  If the AP can't hear the return signal, then it's a lost cause.

ading to Leo...

Ahmed,

its better to plan for site survey to get the real overview of the coverage.

Its also depend on your requrement..

how many user...

which kind of services u will use...

and many otthes...

So it will be good if u do site survey with the help of any IT support partner.

Hi Ahmed,

Normally  supported amount by Cisco's terms of client link or mac address. RULE OF THUMB 25 clients per ap no matter what type of ap.  This can change depending on the applications that will be use.

Ideally for data you can expect 20 clients per ap. If you are doing voice and video on wifi, i would like to 5-15 or so.

stick with 20-25 and you should be good unless your doing voice or video.

consider this ..u can plant for sitesurvey and calculate number of APs for deployment. Thats the reason we are saying to get help from IT support partner for site survey.

Put ur all requirment in front of them.

Regards

You mentioned controllers but your AP model is a SAP (Standalone). You would need a CAP (capwap) model AP.

No one here can tell you how many AP's you need not where they should be located or give you advice on this. Like everyone else mentioned here, you need to get a site survey performed from a qualified partner so they can tell you how many AP's, the AP models, where they should be mounted and what type of antennas.
