New Cisco Aironet IEEE 802.11ac Wave 2 Access Points

    During 2012-13. More than 200 products meeting the 802.11ac specification have appeared on the market. This product range is now referred to as Wave 1.

    The IEEE 802.11 WiFi Wave 2 Specification is the latest officially approved edition of the IEEE 802.11ac standard. The Wave 2 is

    SS - Spatial Streams (spatial streams)
    SU-MIMO - Single-User Multiple Input, Multiple Output
    MU-MIMO - Multiple-User Multiple Input, Multiple Output, a unique feature of 802.11ac Wave 2.
    3x3,4x4 - 3x3 MIMO APs have three antennas and three transceivers; 4x4 - four and four.

    MIMO capabilities (Multiple Input, Multiple Output) were implemented in 802.11n and 802.11ac Wave 1 products, but only in single-user mode (SU-MIMO). Multi-User mode (MU-MIMO) is a new feature that appeared only in 802.11ac Wave 2. MU-MIMO allows more efficient use of currently free transmitters.

    Mobility Express for SMEs

    The Cisco Mobility Express Solution is specifically designed to help small and medium-sized networks easily and cost-effectively provide enterprise-class wireless access to their employees and customers. With the Mobility Express solution, small and medium-sized networks can now have the same quality characteristics as large corporate networks.

    The Cisco Mobility Express Solution is ideal for small to medium deployments. It can be completed in less than 10 minutes and does not require a separate physical controller device. At the same time, it is possible to control other access points of the Aironet 1700, 2700 and 3700 series.

    Key Benefits of Cisco Mobility Express Solution. The solution is fully deployed on access points of the Cisco Aironet 1830 and 1850 series. It manages up to 25 access points that can be added as the network grows. All you need to do is three simple steps using the Setup Wizard software.

    Details to see the entire process of deploying Mobility Express can be seen on YouTube in the next video . Shown here are the configuration, as well as simple configuration of the solution in the corresponding software.

    Additional Information The

    full specifications for the Cisco Aironet 1830 Series and Cisco Aironet 1850 Series are listed here and respectively.here .

    The 1800 series models feature two access points - 1832 and 1852 (the first two rows of the table). Their difference is that 1832 is available only with internal antennas, and 1852 - with internal and external. The second difference is the number of spatial streams (2 and 4), MIMO modes (3x3 and 4x4) and, as a result, the maximum data exchange rate. The access point 1832 provides up to 860 Mbit / s, 1852 - up to 1.7 Gbit / s.

    All 1800 Series access points are powered by PoE (Power over Ethernet) technology. For 1832 points, PoE 3 classes (15.4 W) is enough. Points 1852 to work with full transceiver power requires increased PoE power (25.5 W).

    Both access points can also be powered by a power supply or power injectors. For points 1852, power injectors of increased power AIR-PWRINJ4 are used, but they can work with AIR-PWRINJ5 at lower speeds, because not all transceivers are active at the same time.

    The dimensions and weight of the devices are model independent. The kit includes the point itself and its mount.

    Application. Evolving Wi-Fi Standards IEEE 802.11

    The final version of the 802.11ac Wave 2 standard (end of 2013) includes some improved technical specifications for devices that were not included in the 802.11ac Wave 1 edition. In 2014, Wave 2 class products appeared on the market .

    The evolution of IEEE 802.11 standards

    The advantages of 802.11ac Wave 2 over 802.11ac Wave 1 and other earlier WiFi standards can be summarized in the following four points.

    - Higher data transfer rates - up to 2.6 Gbps in the 5 GHz band.
    - Support for Multi-User MIMO (Multiple-Input, Multiple Output).
    - Support for a channel width of 160 MHz, which is a key feature to provide increased data transfer rates.
    - Fourth Spatial Stream: Supports four antennas and streams compared to three for Wave 1 devices.

    The 802.11ac Wave 1 and Wave 2 products are fully compatible.
