SNAP! is a scalable, rugged WiMAX platform based on the IEEE 802.16e-2005 standard. SNAP! uses the same infrastructure components of ^BroadbandcorDECT-NG network. With the introduction of a SNAP! Base Station into the existing network, operator can start offering WiMAX service, thus providing a seamless upgradation path. SNAP! uses a 5 MHz/10 MHz bandwidth in the 2.3 GHz or 3.4 GHz frequency range. The same platform can offer both ^BroadbandcorDECT-NG service and WiMAX service to subscribers, making it a flexible platform reducing operator’s CAPEX.

SNAP! leverages the ^BroadbandcorDECT-NG architecture with replacements to the Base Station and Subscriber Terminal to provide a WiMAX air interface. The corVAN acts as the ASN Gateway (according to Profile-C deployment of WiMAX Forum) and provides the backbone connectivity. Optionally, the ASN gateway functionality can be provided at the BSA that can directly connect to the Internet backbone (according to Profile-B deployment of WiMAX forum - shown in dotted lines in the figure). The WiMAX Base Stations (SBS) are rugged outdoor units, which operate in the 2.3 GHz/3.4 GHz frequency band, and connect to the Base Station Aggregator on Ethernet links. The Base Stations comply to IEEE 802.16e-2005 standard allowing fixed, nomadic and mobile wireless subscribers.

SNAP! inter-operates with any standard WiMAX fixed and mobile terminal. SNAP! supports quad play services (Voice, Video, Data and nomadic service) in order to provide last mile connectivity to fixed (Indoor & Outdoor) and nomadic customers. It can be configured for providing service to small, medium and large market segments including small office, home office, multi dwelling units, multi tenant units, small/medium enterprises.

The Base Station Aggregator (BSA) of the SNAP! system is designed to be outdoor/indoor mounted (typically at the bottom of the tower). BSA also can be configured to provide ASN gateway functionality. This allows the BSA to be directly connected to the Internet Backbone that allows small-scale data network deployment. The BSA provides power feed to the Base Station apart from providing a high-speed data link over fiber to the Base Stations on tower top.

The SNAP Base Station (SBS) ! is a compact weatherproof outdoor unit which is mounted on tower-top, and is compliant to NEMA and IP ratings for outdoor mounting. Providing the Base Stations on tower-top reduces the RF Cable length from the Antenna to the Base Station saving both cost and loss in the RF cable. The SNAP! Base Stations is compliant to IEEE 802.16e-2005 standard. Base Station deployment is typically done in clusters on a tower (cell-site). Each cell-site contains 1/3/4 Base Stations (Sectors) which provide sectorised coverage around it.
