Harnessing the RF spectrum is just the beginning. With IW Asia, customers can make sure that their WWAN and WLAN capacity matches their user requirements, in addition to supporting current and emerging wide area protocols for voice and data. Carrier Flexibility Horizon supports current and emerging WWAN protocols for both voice and data, and IW Asia  works with each carrier to ensure the carrier network donor equipment provides adequate capacity for each installation. Horizon uses simple carrier connectivity architectures that are used by all major carriers. Modular carrier-grade RF/Fiber optic connectivity modules cover all WWAN frequencies and are seamlessly scalable to meet both frequency and capacity needs. A single Horizon system can provide support in excess eight carriers. More Wi-Fi Capacity IW Asia implements Wi-Fi using an innovative, next-generation architecture known as Layered WLAN. Utilizing advanced signal filtering, Horizon provides pervasive coverage and enables a coverage area to be served by multiple access points and multiple managed traffic channels. IW Asia  can groom all Wi-Fi traffic across the multiple channels and ensure that advanced application requirements are met or exceeded. By dedicating separate WLAN channels to life-critical, mission-critical and casual applications, Layered WLAN eliminates competition that naturally occurs when using a single access point as a shared resource for all wireless traffic. This is a distinct advantage when compared to traditional deployments. Overall, Horizon layered WLAN provides the following advantages: Uniform channel planning Guaranteed signal-level coverage Traffic grooming to handle increased number of clients and user clustering Inherent redundancy Simplified operations via physically collocated and secured access points In fact, these advantages can significantly enhance network performance by two-to three-fold while simplifying the management of 802.11 b/g, a, and n. Testing of Horizon layered WLAN, conducted by independent research firm Novarum, has determined: Horizon allowed organization of client traf?c into different isolated layers, and this led to better performance. Horizon allowed the delivery of more than double the data capacity of the discrete microcellular system in our tests. Horizon exhibited lower interference between APs in the same system than the microcellular system. The clients on Horizon exhibited more uniform and predictable performance. On all of the voice tests, the clients on Horizon had much lower jitter and slightly better MOS scores. Horizon did not compromise the basic functionality of the Wireless LAN system. All of the expected features worked well on the L-DAS. Roaming, voice support, QoS mechanisms and 802.11a/b/g and 802.11n (with 20 or 40 MHz channels) worked on Horizon with the same clients and software as the discrete microcellular system. WWAN or WLAN, voice or data, IW Asia can meet your needs as traffic grows or as applications are added – without any disruption or compromised network performance.
