More about LIBRA 5800
LIBRA 5800's effective throughput is very competitive with other 5.8 GHz OFDM-based wireless offerings, and its effective spectral efficiency is best-in-class. This allows customers to provide more throughput with limited spectrum. The following table compares the throughput and spectral efficiency of LIBRA 5800 against other wireless products based on 64-carrier W-OFDM that is similar to the IEEE Standard 802.11a. While 64-carrier IEEE 802.11a-like W-OFDM products boast a maximum link rate of 54 Mbps, the effective (TCP (1) (Transmission Control Protocol) The reliable transport protocol within the TCP/IP protocol suite. TCP ensures that all data arrive accurately and 100% intact at the other end. ) throughput is comparable to LIBRA 5800, and the effective spectral efficiency of these products is much less than LIBRA 5800 because they use approximately twice as much spectrum:

LIBRA's NLOS capability increases fixed wireless access subscriber coverage from levels delivered by conventional wireless products of 50% or less, to levels that can exceed 90%. NLOS also makes installation much simpler and less costly, reducing the service provider's required investment. Installation and network set-up is further simplified with quick start menus and PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). support eliminating the need for a laptop computer. LIBRA also offers tiered service management through CIR/MBR (Committed Information Rate (communications) Committed Information Rate - (CIR) The guaranteed average bandwidth of a virtual circuit in a frame relay network. The CIR plus the Excess Information Rate (EIR, burst rate) is equal to or less than the speed of the access port into the network. / Maximum Burst Rate). The lightweight single unit design eliminates the need for expensive accessories and coaxial cable, is faster and less expensive to install, and can be mounted indoors or outdoors without the need for any climate control. These characteristics combine to significantly improve the service provider's business model by providing an improved return on a smaller required investment and a much shorter investment payback period Payback Period

LIBRA 5800's flexible and scalable design supports both point-to-point and point-to-multipoint applications, and can be configured with either an integrated antenna or an external antenna. For point-to-point applications, LIBRA 5800 series includes Rapid Deployment (RD) and Extended Range (ER) products, and for point-to-multipoint applications Access Point (AP), Customer Premises Equipment See CPE. (CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises.
CPE - Customer Premises Equipment ) and Long-range Customer Premises Equipment (LCPE) products are available. The point-to-point systems can deliver a data rate of up to 32 Mbps and a line-of-sight range of up to 66 kilometres (41 miles). The point-to-multipoint systems can deliver an aggregated data rate of up to 192 Mbps per six-sector cell and a line-of-sight radius of up to 35 kilometres (22 miles), with up to 2000 CPE's or LCPE's per sector. Subscriber coverage is further improved by LIBRA 5800's 10 MHz channel size. Only 12.5 MHz separation is required between center frequencies, allowing up to 10 non-overlapping channels to be deployed in the 125 MHz available in the 5.8 GHz license-exempt frequencies (5.725 GHz to 5.85 GHz). LIBRA 5800's narrow 10 MHz channel size makes it relatively simple for customers to avoid interference by utilizing radio frequencies that are not being used by others, compared to competitive offerings that use approximately 20 MHz per channel, making them less robust in crowded radio frequencies.
The current hardware is capable of supporting several generations of enhancement to the system software. Features such as dynamic modulation, dynamic power control, and additional network management features are being made available, as the market requires, via over-the-air software upgrades. Also, current products will have a migration path to future products based on the IEEE 802.16a (North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. ) and emerging ETSI BRAN HyperMAN (European and international) standards.

Notes: (1) The W-OFDM Advantage
Wi-LAN's patented Wide-Band Orthogonal Frequency Division Multiplexing (W-OFDM) technology is a variation of OFDM that further improves its characteristics. The signal reception is corrected for distortions, allowing greater transmission speeds, and the signal is processed to maximize the range and multipath resistance. W-OFDM allows spectrally efficient, non-line-of-sight, point-to-multipoint wireless networks to be implemented while minimizing interference with adjacent networks.
(2) The MC-DSSS MC-DSSS Multi-Code Direct Sequence Spread Spectrum (Wi-Lan) Advantage
Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum technology (MC-DSSS) makes it possible to multiply the carrying capacity carrying capacity
the number of animal units that a farm or area will carry on a year round basis, including that needed for conservation of winter feed. Usually stated as dry cows or dry sheep equivalents per hectare. of traditional spread spectrum systems by as much as ten times.
(3) The VINE Advantage
Wi-LAN's patent-pending Versatile Intelligent Network Environment (VINE) technology permits the implementation of long distance, medium subscriber density, broadband Internet access Broadband Internet access, often shortened to just "broadband", is high speed Internet access—typically contrasted with dial-up access over modem.
Dial-up modems are generally only capable of a maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a networks a node-at-a-time. VINE networks deal with Non-Line of Sight (NLOS) limitations in a cost-effective manner by using an anypoint-to-multipoint topology. Established network nodes can be used as repeaters for other nodes that do not have either Line-of-Sight (LOS) or direct connectivity to the base station node.

For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. ) is an organization that provides Internet access See how to access the Internet. to its customers. Other services, such as voice communication and video broadcast, may be bundled with the Internet access service.
(5) NLOS (Non-Line-of-Sight or Non-LOS) capability allows fixed wireless access networks to be configured without the requirement that antennas at the customer premises locations be visible from the base station antenna. This capability increases fixed wireless access subscriber coverage, from conventional levels of 50% or less, to levels that can exceed 90%, making the wireless service provider's business model much more compelling, particularly in high-density urban areas.
