FullMAX™ is an end-to-end, private, broadband wireless data communications network developed specifically for electric utilities and other mission critical industries.
FullMAX™ networks are designed to be deployed over very large service territories of varying terrain. This includes the most rural geographies to the densest urban environments.
A FullMAX™ broadband data network is owned and operated by the utility or end customer in a manner similar to a private land mobile radio system (PLMR). In fact, most of our customers deploy FullMAX™ using the same towers and backhaul as their LMR system.
- All FullMAX™ radios work in any and all licensed frequencies below 1 GHz.
- All FullMAX™ radios have high transmit power as standard.
- All FullMAX™ radios have software configurable channel sizes ranging from 50 kHz to 5 MHz.
FullMAX is based on ieee802.16e and employs Orthogonal Frequency Division Multiple Access (OFDMA). This is in strong contrast to other private licensed wireless solutions which are based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). OFDMA based technologies are spectrally efficient with predictable data rates, latency and quality of service.
FullMAX uses Time Division Duplexing (TDD) which means that each channel carries both upstream and downstream data traffic. This is in direct contrast to frequency division duplexing (FDD) in which there is a dedicated uplink and downlink channel. FDD networks are especially inefficient in private wide area networks where data traffic symmetry varies. In FullMAX, the uplink / downlink ratio is configurable. And in our experience, many utility private networks have asymmetric uplink data traffic.
FullMAX also employs Adaptive Modulation and Coding (AMC). The data rate in the uplink and downlink adjusts in real time according to the link quality. In FullMAX, modulation and coding is determined by the Carrier to Interference-plus-Noise Ratio (CINR). Data rates become predictable based on the CINR of the link and can range from 0.5 bits per hertz per second to 2 bits per hertz per second.
A FullMAX network consists of our high power FullMAX BS1000 base stations, FS4500 Outdoor Remote radios and our highly compact Cobalt-Plus Remote radios.
The entire system operates in licensed frequencies already owned or easily acquired by the customer. (Don’t worry about frequencies if you don’t already have them. We have partnered with a number of frequency holders to supply frequencies. All FullMAX™ radios work in all frequencies below 1 GHz so we have lots of options.)
Figure 2 shows a sample network diagram for a single cell deployment. The BS1000’s (A) are installed at the customer’s tower sites (B) which are typically already equipped with a high capacity microwave or fiber link back to the central office. The BS1000 (A) is designed to be installed inside the tower shelter (C) with the other tower communications equipment. Most customers already have a router installed to which we connect through Ethernet. FullMAX is application agnostic and provides a Layer 2 Ethernet connection over the air to all the remote devices. Depending on the scale and scope of the network rollout, the customer will use either an omni-directional or sectored base station antenna mounted high on the tower.
Once installed and running, the customer now has 30 miles of non-line of site coverage in all directions from the tower. This effectively creates an IP cloud in which any number of FS4000 fixed stations (D) and MS4000 mobile stations (E) can be deployed. We can design the system for various remote antenna heights. A typical fixed network is designed for a remote directional antenna height of 20 feet. For mobility, we design for a roof mount vehicle antenna at 6’.
The Network Management System NMS1000 (F) is located on a server back at the Network Operations Center (G). The NMS1000 allows the customer to monitor the remote network across the entire service territory.
