Cisco Aironet 1830 Series access points are indoor, dual-band 802.11ac Wave 2 platforms intended for small and medium-sized networks. The series supports centralized controller operation, Cisco Mobility Express, FlexConnect, OfficeExtend, monitor, sniffer, standalone, and mesh deployment modes. Its primary hardware profile is the Aironet 1832i, which uses internal omnidirectional antennas and provides a maximum 5 GHz PHY data rate of 867 Mbps with an aggregate dual-radio data rate of up to 1 Gbps.
Product Positioning and Deployment Scope
The Aironet 1830 Series is designed for indoor enterprise wireless deployments where clients include smartphones, tablets, and laptops supporting 802.11ac Wave 1 or Wave 2. The platform combines 3×3 MIMO radio hardware with two spatial streams, multiuser MIMO, transmit beamforming, and support for 20 MHz, 40 MHz, and 80 MHz channels on 5 GHz.
The series can be deployed in the following modes:
- Centralized controller-based operation
- Standalone operation
- Cisco FlexConnect
- Sniffer
- Monitor
- OfficeExtend
- Mesh
- Cisco Mobility Express
Sniffer, monitor, OfficeExtend, and mesh capabilities are identified in the specification as future-supported functions. Cisco Mobility Express provides a controller function on the access point and is intended for small and medium-sized deployments that require multiple access points without a separate physical wireless controller.
OfficeExtend allows an Aironet or Catalyst access point to provide a remote worker or micro-office with access to corporate wireless services. The feature is intended for remote locations where the user requires corporate SSID and network access without configuring a separate VPN manually.
Cisco User Defined Network is identified as a Cisco DNA Center feature associated with the platform. It allows end users to receive a controlled wireless network partition on a shared infrastructure. The stated examples include university dormitories and extended hospital stays, where users require device isolation and control over which devices can connect.
Wireless Architecture and Throughput
The Aironet 1830 Series provides two wireless bands:
- 2.4 GHz for 802.11b/g/n operation
- 5 GHz for 802.11a/n/ac operation
The 5 GHz radio supports 802.11ac Wave 1 and Wave 2 with a maximum PHY rate of 867 Mbps using an 80 MHz channel and two spatial streams. The total aggregate dual-radio PHY data rate is up to 1 Gbps. These are PHY-layer rates; application throughput will be lower and depends on channel width, client capability, contention, protocol overhead, signal quality, interference, and network services.
The radios support:
- 3×3 MIMO
- Two spatial streams
- Single-user MIMO
- Multiuser MIMO
- Maximal Ratio Combining
- Transmit beamforming
- Cyclic Shift Diversity
- A-MPDU transmit and receive aggregation
- A-MSDU transmit and receive aggregation
- Dynamic Frequency Selection
- 20 MHz, 40 MHz, and 80 MHz channels on 5 GHz
- 20 MHz and 40 MHz channels for 802.11n
MU-MIMO allows the access point to transmit data to multiple compatible 802.11ac Wave 2 clients simultaneously. This capability is most relevant in environments with multiple capable clients transmitting or receiving concurrent traffic. It does not convert all client traffic into simultaneous transmissions, because the benefit depends on client radio support, spatial stream behavior, channel conditions, and traffic patterns.
Transmit beamforming improves downlink performance to mobile devices, including one- and two-spatial-stream 802.11ac clients. It can also reduce the transmit effort required by some mobile devices, which may contribute to improved battery behavior.
Supported Controllers and Software
The access point requires Cisco Unified Wireless Network Software Release 8.1.121.0 or later when used with AireOS wireless controllers.
Supported controller platforms include:
- Cisco 2500 Series Wireless Controllers
- Cisco 3500 Series Wireless Controllers
- Cisco Wireless Controller Module for ISR G2
- Cisco Wireless Services Module 2 for Cisco Catalyst 6500 Series Switches
- Cisco 5500 Series Wireless Controllers
- Cisco Flex 7500 Series Wireless Controllers
- Cisco 8500 Series Wireless Controllers
- Cisco Catalyst 9800 Series Wireless Controllers
- Cisco 5760 Wireless LAN Controller
- Cisco Catalyst 3650 and 3850 Series Switches with integrated controller
- Cisco Mobility Express
For presales design, the controller selection must be made before finalizing the access point software and licensing model. Catalyst 9800 deployments require a Cisco DNA subscription license for the access point. The supported subscription tiers are Cisco DNA Essentials and Cisco DNA Advantage. The associated perpetual feature levels are Network Essentials and Network Advantage.
Cisco DNA subscriptions are available for 3-year, 5-year, or 7-year terms. If the subscription is not renewed, subscription features expire while Network Essentials or Network Advantage functions remain available according to the purchased entitlement.
The licensing mechanisms described are:
- Smart Licensing, which provides centralized entitlement visibility and license pooling
- Specific License Reservation, which supports node-based licensing in networks that do not communicate licensing usage information externally
The controller licensing level can be configured as Cisco DNA Essentials, Cisco DNA Advantage, Network Essentials, or Network Advantage. Controller initial bootup is identified as operating at the Cisco DNA Advantage level.
Radio Data Rates
Legacy rates include the following:
- 802.11a: 6, 9, 12, 18, 24, 36, 48, and 54 Mbps
- 802.11g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 Mbps
802.11n supports MCS 0 through MCS 23. The documented maximum 802.11n PHY rate is 300 Mbps using 40 MHz at 5 GHz, two spatial streams, and a 400 ns guard interval.
Selected 802.11n maximum rates include:
| Spatial streams | Channel width | Guard interval | Maximum rate |
|---|---|---|---|
| One | 20 MHz | 800 ns | 65 Mbps |
| One | 40 MHz | 800 ns | 135 Mbps |
| One | 20 MHz | 400 ns | 72.2 Mbps |
| One | 40 MHz | 400 ns | 150 Mbps |
| Two | 20 MHz | 800 ns | 130 Mbps |
| Two | 40 MHz | 800 ns | 270 Mbps |
| Two | 20 MHz | 400 ns | 144.4 Mbps |
| Two | 40 MHz | 400 ns | 300 Mbps |
For 802.11ac, the maximum documented two-stream rate is 866.7 Mbps at MCS 9, 80 MHz, and a 400 ns guard interval. The datasheet also identifies an 80 MHz two-stream rate of 780 Mbps with an 800 ns guard interval.
The maximum 802.11ac rates by spatial stream configuration are:
| Spatial streams | Channel width | 800 ns guard interval | 400 ns guard interval |
|---|---|---|---|
| One | 20 MHz | 78 Mbps | 86.7 Mbps |
| One | 40 MHz | 180 Mbps | 200 Mbps |
| One | 80 MHz | 390 Mbps | 433.3 Mbps |
| Two | 20 MHz | 156 Mbps | 173.3 Mbps |
| Two | 40 MHz | 360 Mbps | 400 Mbps |
| Two | 80 MHz | 780 Mbps | 866.7 Mbps |
The 2.4 GHz radio is hardware-capable of 40 MHz 802.11n operation, but only one nonoverlapping 40 MHz channel is identified. For most enterprise designs, 20 MHz operation should be treated as the practical planning basis on 2.4 GHz.
Channel Planning and Regulatory Domains
The maximum number of nonoverlapping channels varies by regulatory domain. The general channel counts stated by the datasheet are:
| Band and standard | Channel width | Maximum nonoverlapping channels |
|---|---|---|
| 2.4 GHz 802.11b/g | 20 MHz | 3 |
| 2.4 GHz 802.11n | 20 MHz | 3 |
| 2.4 GHz 802.11n | 40 MHz | 1 |
| 5 GHz 802.11a | 20 MHz | 25 |
| 5 GHz 802.11n | 20 MHz | 25 |
| 5 GHz 802.11n | 40 MHz | 12 |
| 5 GHz 802.11ac | 20 MHz | 21 |
| 5 GHz 802.11ac | 40 MHz | 12 |
| 5 GHz 802.11ac | 80 MHz | 6 |
The exact available frequencies differ by regulatory domain. Domains identified include A, B, C, D, E, F, H, I, K, N, Q, R, S, T, and Z. Country approval must be verified before ordering and deployment. Not all regulatory domains are necessarily available in all countries.
Presales channel planning should account for the reduction in channel reuse when 40 MHz or 80 MHz channels are selected. Wider channels increase the peak PHY rate but consume more spectrum and can reduce the number of independent cells available for dense deployments. High-density designs should therefore be evaluated using client density, application mix, required minimum data rates, channel reuse, co-channel contention, and 5 GHz channel availability rather than the maximum headline rate alone.
RF Performance
The integrated antennas are internal omnidirectional designs:
| Band | Antenna gain | Horizontal beamwidth |
|---|---|---|
| 2.4 GHz | 3 dBi | 360 degrees |
| 5 GHz | 5 dBi | 360 degrees |
Maximum transmit power is:
| Band | Radio mode | Maximum transmit power |
|---|---|---|
| 2.4 GHz | 802.11b | 22 dBm |
| 2.4 GHz | 802.11g | 22 dBm |
| 2.4 GHz | 802.11n HT20 | 22 dBm |
| 5 GHz | 802.11a | 23 dBm |
| 5 GHz | 802.11n HT20 | 23 dBm |
| 5 GHz | 802.11n HT40 | 23 dBm |
| 5 GHz | 802.11ac non-HT80 | 23 dBm |
| 5 GHz | 802.11ac VHT20 | 23 dBm |
| 5 GHz | 802.11ac VHT40 | 23 dBm |
| 5 GHz | 802.11ac VHT80 | 23 dBm |
Available transmit power settings are 22, 19, 16, 13, 10, 7, 4, and 1 dBm on 2.4 GHz. On 5 GHz, the available settings are 23, 20, 17, 14, 11, 8, 5, and 2 dBm.
Actual maximum power depends on the selected channel and country regulations. The access point’s transmit power should be coordinated with the client population and neighboring cells. Maximum transmit power is not automatically the correct value for a balanced design, because client transmit capability may be lower than access point capability.
Representative receive sensitivity values include:
- 802.11b: -101 dBm at 1 Mbps and -89 dBm at 11 Mbps
- 802.11g: -96 dBm at 6 Mbps and -79 dBm at 54 Mbps
- 802.11a: -96 dBm at 6 Mbps and -79 dBm at 54 Mbps
- 802.11ac two-stream VHT80: -86 dBm at MCS 0, -67 dBm at MCS 7, -63 dBm at MCS 8, and -61 dBm at MCS 9
Higher MCS rates require stronger signal conditions. Coverage acceptance should therefore use the required minimum RSSI, SNR, and application data rate rather than the lowest sensitivity figure.
Interfaces, Power, and PoE Planning
The hardware interfaces are:
- One 10/100/1000BASE-T autosensing RJ-45 Ethernet interface
- Power over Ethernet support
- One RJ-45 management console port
- One USB 2.0 port, identified as enabled through future software
The access point requires 44 to 57 VDC. External power supplies and injectors accept 100 to 240 VAC at 50 to 60 Hz.
Nominal power draw is 15.4 W. Power draw from the power sourcing equipment can be higher because of cable losses. Supported powering options include:
- IEEE 802.3af
- IEEE 802.3at
- Enhanced PoE
- Cisco local power supply AIR-PWR-C=
- Cisco power injector AIR-PWRINJ5=
- Cisco power injector AIR-PWRINJ6=
AIR-PWRINJ5= supports 802.3af only. When the access point is powered by 802.3af PoE, the USB port is disabled.
Presales PoE rules are straightforward:
- Validate that the switch supports the required PoE standard at the intended port.
- Budget 15.4 W for the access point and allow additional sourcing-equipment overhead for cable loss.
- Do not promise USB availability when using 802.3af.
- Use 802.3at, Enhanced PoE, or local power when the design requires the USB interface or additional power margin.
- Confirm the injector model when the access point is installed without a PoE switch.
Physical and Environmental Specifications
The access point measures 8.3 x 8.3 x 2 inches, or 210.8 x 210.8 x 50.8 mm, excluding the mounting bracket. Weight is 2.05 lb, or 930 grams.
Environmental limits for the Aironet 1830i are:
| Parameter | Specification |
|---|---|
| Operating temperature | 32 to 104 degrees F, 0 to 40 degrees C |
| Storage temperature | -22 to 158 degrees F, -30 to 70 degrees C |
| Operating humidity | 10% to 90%, noncondensing |
| Operating altitude test | 40 degrees C at 9843 ft |

The supplied datasheet does not specify mean time between failures, fan operating limits, or acoustic noise in dBA. Acoustic noise planning is therefore not supported by a published value in the supplied specifications. The access point should be treated as an indoor fixed network appliance, and installation conditions must remain within the stated temperature, humidity, and altitude test limits.
