Description
Motorola’s EXPEDIENCE Platform is an Indoor true NLOS (Non Line Of Sight) Wireless Broadband platform specifically optimized for point-to-multipoint voice and data services, which provides a robust easy to install and highly scalable infrastructure for licensed frequency bands.
The system provides a ‘carrier-grade’ solution, allowing the operator to successfully compete against other fixed and wireless broadband access architectures.
The Expedience system is a standards based wireless network platform that supports delivery of IP - compatible broadband applications, including voice and data services such as IP telephony and video streaming. Recognized for its user simplicity and immunity to multi-path interference, the Expedience system offers service providers NLOS performance, and network efficiency, without sacrificing bandwidth to achieve broad coverage. It is the first and only NLOS wireless broadband system to deliver consistent throughput across an entire cell.

Subscriber Units, also known as CPE’s, can be either indoor gateway units, integrated outdoor wall-mount gateways, or vehicular mobile units (for instance for public safety and transportation applications).
The indoor subscriber unit functions as a wireless IP gateway into the home or small-medium-enterprise (SME). This gateway enables the subscriber to run Ethernet applications on a broadband connection that can be extended locally with a Wi-Fi (hot spot) as well. The wireless IP gateway incorporates plug & play functionality. The subscriber unit is self-provisioning and does not require professional or truck-roll installation. The user simply plugs the Ethernet cable into a laptop or desktop computer and opens the browser. The user is not required to install any software, or to configure his/her laptop or PC. |

The system integrates the following technologies:
- OFDM - (Orthogonal Frequency Division Multiplex) The physical layer protocol of choice for true non-line-of-sight and 4th generation broadband networks. The OFDM solution utilizes hundreds of individual carriers and a patented process of mapping a user’s data to those carriers, to actually leverage the presence of multi-path to transmit and receive robustly in the NLOS service environment.
- TDD - (Time Division Duplex) Upstream and downstream links on the same 6MHz RF channel provides the highest flexibility in frequency utilization. No need to use multiple channels or to have guardbands between downstream and upstream channels.
- AMOD - (Adaptive Modulation) Enables higher capacity per sector and a robust RF link all the way to the edge of the wireless cell. AMOD can double the capacity per sector over a single modulation level.
- DBD - (Direct Burst Detection) The Expedience patented equalization and detection scheme eliminates the need for equalizer training sequences before sending actual data. DBD minimizes latency of user packets and optimizes the efficiency of the Expedience MAC protocol.
- Expedience MAC - The Expedience patented MAC architecture is the first protocol designed specifically for last mile broadband wireless data networks to optimize the scheduling and delivery of data and voice packets over a multiuser NLOS airlink.
- Ethernet Networking – The Expedience utilizes industry standard Ethernet networking interfaces for base stations and CPEs to provide an elegant solution for scaling and managing the broadband network at both the cell site, and the enterprise or home. No need to configure base station site controllers and clunky point-to-point connection protocols, Expedience is networked and managed like other standard Ethernet networks. Expedience subscriber units plug directly to PC’s or Ethernet switches/routers for simple, always-on, home or office connectivity that is compatible with existing equipment.

o NLOS (Non line of sight) Range:
o Rural environment: up to 30 Km
o Semi-urban Indoor environment: 8 Km
o Urban Indoor environment: 4,5 Km
o Uniform broadband data rates throughout the cell
o True plug-and-play subscriber unit
o Modulation: OFDM automatic adaptative modulation 4/16/64 QAM to maximize the capacity of the airlink.
o RF Access Mode: Time Division Multiplex (TDD)
o Bandwidth profiles by type of user (Service Level Agreements, SLA).
o Software upgrade of service “over the air”.
o Voice and data service capabilities available from each CPE.
