Cisco Aironet 1242AG Access Point & Diversity Antenna Package
Our Cisco 1242AG diversity package includes everything needed to set up a wireless network in challenging environments such as warehouses, factories, retail stores, and other large spaces where obstructions such as metal racking and structural variations may affect packet delivery.
The AIR-AP1242AG-A-K9 has a rugged metal enclosure and a broad operating temperature range, making it suitable for a wide range of deployment locations. This access point can be powered by 802.3 PoE (Power over Ethernet), Cisco inline power switches, single port power injectors, such as the AIR-PWRINJ3, or local power through Aironet AIR-PWR-A.
Condition: Pre-owned in good condition
Overview of the Benefits of Using a Diversity Antenna
Deploying wireless technology in today's diverse environments requires using hardware and software capable of offsetting and eliminating some of the common negative effects these environments have on wireless signals. Large, cluttered spaces filled with metal shelving and racks, coupled with the varying composition of structural components such as walls, ceilings and roofs, offer an array of factors that lead to poor network performance and, in some instances, failure. This condition is known as Multipath Distortion and can lead to Packet loss, decreased bandwidth, and signal nulling, which can wreak havoc on a network and cause loss of productivity and data.
When signals reflect, refract and diffract off objects, it can delay the packet's arrival and can harm the integrity of the packet as well. The receiving access point will then get multiple versions of the packet and have to shift through them to determine which one it will use. This can confuse the access point, causing errors.
By deploying a Diversity Antenna, you can minimize, if not eliminate, some of these negative effects. Diversity utilizes two antennas instead of one to essentially “pick” the best signal. Due to the antennas being in separate physical locations they are able to sample two different zones in the transmission range. This increases the likelihood the access point will field a signal that’s usable. It will "see" the same signal from two different points of view, compare them, and then pick.
In addition, the 802.11 wireless standard requires that the access point receiving the data send an acknowledgement packet confirming receipt. If the data is corrupt, null or takes too long, no acknowledgement packet is sent and the transmitting access point will re-send. The more bad data, the more re-sent packets and the longer the packets in queue will have to wait to be sent from the transmitting access point.
