Don’t accept the status quo…dual-radios for the cost of single-radio with new AP-103

Aruba Employee

We are happy to announce the new entry level Aruba AP-103 product that is the next generation of the AP-92/93 (NOTE: we continue to sell these models) that brings several new enhancements for low-cost/low-density environments. The AP-103 leverages 802.11n with 2x2:2 MIMO to deliver up to 300 Mbps per radio.





First it matches the current list price of the AP-92/93 while extending from having a single-radio to now being a dual-radio Access Point. This enables you to support both the older generation of 2.4 GHz devices (often smartphones) as well as newer dual-band devices that can leverage the less crowded 5 GHz band on the same AP.


Second, given the pervasiveness of cellular DAS systems and the introduction of new LTE bands at 2.6 GHz (LTE and TD-LTE channels 7, 38, 40, 41 sidebands overlap with 2.4GHz), we have incorporated our Advanced Cellular Coexistence (ACC) technology. This unique radio design utilizes filtering to minimize the impact from the 3G/4G LTE network, distributed antenna system and commercial femtocell interference sources in order to maximize performance.


For your environments that need to support a high density of #GenMobile users or the highest performance you should be looking at our 802.11ac products, the AP 220 Series for indoors and the AP 275 Series for outdoors.


The Aruba AP-103 (controller-managed) is available for ordering today and requires a minimum software version of ArubaOS 6.4 (available here). The Aruba IAP-103 (controller-less) will be available later in 1H 2014 and will require a minimum software version of Aruba Instant 4.1.



The Aruba AP-103 is orderable today and you can find more information in the product

data sheet and ordering guide.

Nice AP! just what we needing in latin america to compete agains HP, Rukus and non other cisco product in price.


I got a few questions


Regarding the Max trasmit power

AP 93

Maximum transmit power:

2.4 GHz: 21 dBm (limited by local regulatory requirements)

5 GHz: 21 dBm (limited by local regulatory requirements


AP 103


Maximum (aggregate, conducted total) transmit power (limited
by local regulatory requirements):
2.4-GHz band: +21 dBm (18 dBm per chain)
5-GHz band: +21 dBm (18 dBm per chain)
I dont understand whats the difference
Can you explain us what does that per chain means? why does the AP 93, 105 does not have that  line, and it just says that the maximum transmit power is 21 in the case of ap 93 and 23 in the case of 105.



Great news :)


+ more questions - in continues to NightShade1  post.

  • So why 105 cost more?
  • what are the benfit to deploy 103 vs 105?




Good quetions....


To begin with the answer which i think they are...

105 has a better antenna so better range than the 103, and it migh has better hardware but who knows... the hardware is not posted(cpu, SDRAM, flash memory)


Besides that i cannot think of something else...


But the new thing is that on 103 which is not supported on 105 is the advanced cellular coexistant!


But still its 300 bucks chearper...


If you see they did the same with the AP274/275 and 175... the outdoor 274 cost like the half of the AP 175  which is great for us if competitors CANNOT reduce the cost of their aps like aruba is doing :)






Max transmit power of the AP-103 is the same as for AP-93 (21dBm aggregate/combined), and a little lower than AP-105 (23dBm).

For newer products, we've added the "per chain" numbers to avoid confusion. MIMO devices have multiple radio chains, and some vendor play games with the different ways that power can be specified (per chain, combined, including/excluding antenna gain). 18dBm per chain (conducted, so excluding antenna gain) translates to 21dBm for a 2x2 MIMO device (2x power = +3dB).


The AP-105 costs more because it has a more powerful core, translating to the ability to support higher client densities (exact numbers depend on client type and what these clients are doing). AP-105 also has an extended temperature range and is plenum rated.


Nice explanation Oharms thanks!

Its true 105 support 50C and 103 support 40C


I know that the max number support depends on what the client is doing


Let put it this way

Let say the client just use the APS for internet conectivity, emails and that kind of things

In this scenario how much users per AP you think it would be okay

105 = x ammount of devices

103 = X ammount of devices

What i want to know is how much powerful its the 105 vs 103.


Also thanks for the explanation on the chains! now its more clear.

103 uses less power 

• Maximum power consumption: 9.5W (POE) or 8W (DC)


Than 105

• Maximum power consumption: 12.5 watts


And the Antennas are better in teh 2.4 but little less in the 5 GHz


• Four integrated down-tilt omni-directional antennas for 2x2
MIMO with maximum antenna gain of 3.9 dBi at 2.44 GHz,
4.1 dBi at 5.2 GHz and 4.3 dBi at 5.8 GHz


Four integrated downtilt omni-directional
antennas for 2x2 MIMO with maximum antenna gain of 3.0 dBi
in 2.4 GHz and 4.5 dBi in 5 GHz


So Basically the AP103 might be better for Hotels who always choose  cost :) and for customers that want dual Radio but with low cost, the trick is number of users that the customer will load...


This will be really good for Hotels...


Thanks everyone for summrize all the diffrents - thank u all!


1 More late night question:


IAP-103 (The instant version of that great new cost effective AP) supporting up to 16 units per VC (like AP92/93)  ? or supporting up to 64 units per VC?





There's no fixed x/X ratio. The hard (but unrealistic) limit for the number of client devices is the same for all our APs (255 per radio). For real deployments, the typical number we suggest as the maximum for the AP-103 would be 25 or so, while that would be double that for the AP-105.



25 per AP or 25 per radio ? :)






Marcus said that it will be unlimited like the 105 cluster...

You can read his post on the tread in there!


The limit of the 64 APS is no more... now its unlimited.... the thing is that  there is no a hard limit  but it seems he has saw custumers runnning up to 150 AP in a cluster... the thing is that i suppose those IAPs are the ones with better CPU like IAP 135 :)



25 per radio, but please don't take these numbers as hard spec numbers  ;-)


Oharms those actually are really good numbers. :)

i just wish the instant version were alredy out...




NightShade1 & oharms Thanks for g00d info!
