Cable AML Broadband Wireless Access
Broadband Wireless Access (BWA) and Fixed Wireless Access (FWA) are industry descriptions for two-way, fixed-wireless, high-capacity communication systems specifically designed to provide "last mile" services to large numbers of commercial and residential subscribers.
Broadband describes the capacity or load-bearing capability of the system. Current voice, video, and data applications require the capability to transfer very high volumes of information. As these technologies evolve, the capacity demands will continue to increase. Cable AML BWA systems are truly broadband and capable of meeting these demands.
Wireless refers to the transmission medium used to make the “last mile” connection between the subscriber’s home or office and the base station from which the operator provides the services and applications. Cable AML typically works in the licensed frequency bands from 1.5 to 42 GHz, and our strength rests in our ability to design and produce systems capable of operating at any frequency within these parameters.
Access represents the gateway connection to applications and Services such as video distribution, high-speed data connections, LAN extension capability, Telephony, virtual private networks (VPN), video-conferencing, and broadband Internet access, among others. Each category of application (voice, video, or data) will have its own access technology. Cable AML integrates these technologies into the most flexible BWA systems available today.
The following graphic shows how these 3 parameters relate:

BWA-2000: Broadband Wireless Access Platform
Cable AML offers the industry's most cost-effective and flexible Broadband Wireless Access -- the BWA-2000. BWA–2000 is a system platform encompassing a series of BWA systems custom-tailored to the specific system requirements of the operator.
The BWA-2000 Series of Systems is based on a modular, open, and scalable platform that can be designed precisely for your requirements.
- The BWA-2000 platform can accommodate virtually any licensed frequency band from 1.5 GHz to 31 GHz. In fact, BWA-2000 series includes systems designed at 1.5 GHz, 2.3 GHz, 2.5 GHz, 3.5 GHz, 10.5 GHz, 24 GHz, 26 GHz, and 28 GHz.
- BWA-2000 systems can be deployed in cells of varying size, shape, and customer density -- from hilly and urban to flat and rural.
- BWA-2000 systems can be configured to connect with virtually any base station network and any type of subscriber network topology.
All BWA-2000 systems share:
Superior Design
BWA-2000 systems comprise elements selected precisely to take the risk out of system acquisition. The ultra-reliable RF equipment is based on field-proven designs currently used in systems providing video, data, and multimedia services to millions of subscribers around the world. The Access system has successfully passed through the rigorous DOCSIS qualification/certification process, making the system inherently robust while virtually eliminating any reliability and network compatibility concerns.
Exceptional Value
BWA-2000 systems offer the best price-to-performance ratio of any high-capacity, last mile access system operating in licensed bands. They can be rapidly deployed, enabling operators to quickly begin adding subscribers, and the low cost per subscriber provides operators with shorter payback periods. BWA-2000 systems can be expanded as customers are added. The reliable and easy-to-maintain equipment ensures low installation and maintenance costs, allowing the operator to focus on adding content and subscribers.

Key Characteristics of Cable AML Broadband Wireless Access Systems:
Cost-Saving Subscriber Configuration Options
The most significant expense of any BWA deployment is the customer premises equipment for point-to-multipoint applications. Systems configured to allow sharing of customer premises equipment will reduce deployment costs substantially, therefore, choosing the right subscriber configuration is an important decision. Subscriber equipment offered by Cable AML can be configured in three general categories of subscriber configuration options (see figure below).
The second category is called LAN Subscriber Option, where a single transceiver feeds multiple users through a single subscriber modem. With this option, the subscriber modem is shared by up to 32 users on a local area network which is connected to the shared subscriber modem. This configuration is generally used for commercial subscribers where the LAN is considered a single subscriber.
The third category is the Shared Subscriber Option in which a single transceiver is shared by multiple subscriber networks. The configuration of the subscriber networks sharing the transceiver can vary. They can consist of any combination of a single user, multiple users on a single LAN, or multiple subscribers sharing the same subscriber modem (This network configuration requires a special router to manage the traffic sharing the subscriber modem). The number of subscriber networks is limited only by performance requirements of the aggregated subscribers versus the bandwidth available through the transceiver. This configuration option is appropriate for multi-dwelling and/or multi-tenant locations and offers the greatest potential for cost savings.
All Cable AML BWA systems offer:
High Capacity
Each system can provide very high-speed, bi-directional connectivity to thousands of subscribers by intelligently sharing access using the latest FDM/TDM/TDMA technology, providing the maximum in system flexibility and power.
Standards-Based
Cable AML Broadband Fixed Wireless Access systems allow operators to reap the benefits of and capitalize on the resources and momentum developed by DOCSIS (Data over Cable Systems Interface Specification). Because Cable AML Systems are based on DOCSIS -qualified equipment, operators no longer need to worry about system replacement costs for proprietary wireless access systems that can quickly become obsolete.
Sophisticated Quality of Service
Sophisticated Quality of Service parameters for every type of Service Level Agreement (SLA) can be established and managed, ensuring that each subscriber has access to the contracted bandwidth while optimizing the use of system resources.
Programmable Modulation
By offering programmable modulation formats (QPSK, 16-QAM, and 64-QAM), Cable AML systems are designed to ensure that each subscriber gets the best quality performance using the same subscriber equipment, anywhere within the operating range.
Custom Tailored Frequency Bands
Cable AML Broadband Fixed Wireless Access systems can be configured to accommodate unique spectrum allocations within the licensed 1.5 GHz, 2.5 GHz, 3.5 GHz, 10.5 GHz, 24 GHz, or 28 GHz band ranges.
Broadest Range of Applications
Cable AML Broadband Fixed Wireless Access systems provides High-speed Internet access, LAN Extensions, Virtual Private Networking (VPN), Voice over IP (VoIP), Video Conferencing, Distance Learning, and Dedicated High-speed connections in a single, powerful, and rugged package.
