Recent decades have witnessed increased adoption of wireless communications technologies in a wide variety of applications, including laptop computers, mobile phones, and portable devices. Essentially, the triband compact printed antenna covers 2.4 GHz and 5 GHz (5.2/5.8 GHz) WLAN and 3.5/5.5 GHz WiMAX frequency bands and thereby is a good candidate for WLAN/WiMAX applications. Furthermore, the simulated and measured antenna gains are 1.269–3.074 dBi and 1.10–2.80 dBi, respectively. Specifically, the simulated and experimental radiation patterns are omnidirectional at 2.4, 3.5, and 5.2 GHz and near-omnidirectional at 5.5 and 5.8 GHz. The simulation and experimental results are in good agreement. In this study, simulations were carried out, and a prototype antenna was fabricated and experimented. In addition, the equivalent circuit model consolidated into lumped elements is also presented to explain its impedance matching characteristics. The folded open stub and long and short L-shaped strips realize impedance matching at 2.4, 3.5, 5.2, and 5.8 GHz, and the asymmetric trapezoid ground plane fine-tunes impedance matching at 5.2, 5.5, and 5.8 GHz. Besides, it is of simple structure and operable in 2.4 GHz and 5 GHz (5.2/5.8 GHz) WLAN and 3.5/5.5 GHz WiMAX bands. The antenna structure consists of a folded open stub, long and short L-shaped strips, and asymmetric trapezoid ground plane. Geographic positions in Dashboard are used to tune radio parameters and improve performance.This research presents a triband compact printed antenna for WLAN and WiMAX applications.
For long ranges, it's important to accurately place your access points on Dashboard. It's possible that a particular frequency is better at penetrating an obstruction. If your access points are capable of using both 2.4GHz and 5GHz antenna's consider using them. If your network has many gateways, consider enabling Auto Channel Spreading (Enterprise only). Often changing the channel of your network will avoid congestion and increase your network's speed and range. While the former can be mounted in any direction, the latter should be mounted so that the antenna is perpendicular to the ground. Some antennas produce a spherical coverage area (imagine a soccer ball with the access point directly in the center) other antennas concentrate signal on a single plane (imagine a pancake). Avoid placing access points near devices that emit radio interference. When possible, arrange access points so they have direct line-of-sight with each other. 
Try moving access points to see if speed improves. What channel am I currently using? Is there a lot of radio interference on this channel? How fast is my connection to the access point? If the access point is a repeater, is the AP's path to the gateway strong? Write down these numbers, then make changes to your network and see if they improve or hurt your performance. Visit this page while connected to a Cisco Meraki access point to see live statistics about the access point. Directional antennas (sometimes called "panel antennas") greatly extend range by concentrating power in a single direction.Īlthough there isn't a silver bullet to maximize coverage, there are several rules of thumb to get the most from your equipment: Cordless phones, microwave ovens, and neighboring wireless access points are common sources of interference.īarring physical obstruction and radio interference, Cisco Meraki access points equipped with omnidirectional antennas typically reach 100 meters. Both indoor and outdoor deployments will also be affected by radio frequency interference. The same principles also hold true for outdoor installations: the signal will be attenuated by trees, buildings and certain atmospheric conditions or weather, such as heavy rainfall or fog. For example, in an indoor setting the type and thickness of walls can impact the range of your network fewer walls are better, or uninsulated drywall is better than concrete. Wireless performance depends on a number of factors, making a definitive range hard to predict.
