1.5 Overview of the System
1.5.1 Introduction
MeshNetworks develops Mobile Broadband communications systems with “meshed”
architectures. That is, each node can connect directly, or indirectly (by hopping through other
nodes), with any other node in the network. The peer-to-peer nature of the mesh architecture
combined with data rate control in each subscriber and infrastructure node in the network
insures reliable delivery while providing increased network capacity through geographic reuse of
the frequency spectrum.
The network comprises four distinct elements:
• Subscriber Devices (SDs)
• Wireless Routers (WRs)
• Intelligent Access Points (IAPs)
• Mobile Internet Switching Controllers (MiSCs)
The overwhelming portion of the value that MeshNetworks provides is in the Wireless Modem
Card (WMC). The WMC is used in Subscriber Devices as well as in the Wireless Router and
Intelligent Access Point (IAP), both of which are types of infrastructure equipment.
MeshNetworks provides a Mobile Internet Switching Controller (MiSC) which is assembled from
industry standard equipment and conform to industry standards. MeshNetworks also provides
the network applications which are required for proper operation and value extraction from the
mobile internet system.
Figure 1. Elements of the System
All network elements are designed to support mobile applications. Subscriber Devices can be
either mobile or fixed, while the remaining components are typically fixed. Wireless Routers and
2
Setup and Deployment Guide
IAPs can be mounted on utility poles, light poles, traffic apparatus, billboards, and buildings.
Their fixed positions allow the Subscriber Device to pinpoint its location within one second.
WRs and IAPs can also be mobile, attached to emergency vehicles, utility vehicles, or fleet
vehicles. It is important to note that the WMC technology within a Subscriber Device is identical
to the WMC technology in Wireless Routers and IAPs.
The
with end user data access rates on the order of DSL or Cable Modem. The chosen metric of
network efficiency for a data centric network is bits per second per Hertz per square kilometer
per dollar (bps/hz/km2/$). This metric balances the user data rates, allocated bandwidth,
coverage area, and cost. One of the most important factors in optimizing this metric is the
choice of network architecture.
system was designed to minimize the cost associated with deploying a mobile Internet
1.5.1.1 Subscriber Devices (SDs)
The MeshNetworks’ Wireless Modem Card (WMC) is
provided as a PCMCIA form factor device. The WMC is
used with an off-the-shelf IP-enabled laptop, handheld
computer, PDA, or entertainment device. These two devices
together make up a Subscriber Device (SD).
The WMC provides access to the fixed infrastructure network
and other networks, such as the Internet, and it can also
function as a Wireless Router and repeater for other SDs.
SDs can therefore be a key part of the network
infrastructure. Adding subscribers can effectively increase the number of Wireless Routers in
the network, which increases the number of alternative paths that subscribers may utilize. This
can reduce both the time and cost to deploy network infrastructure, while also increasing the
spectral efficiency and therefore the capacity of the network. And because SDs can also
operate in an ad hoc peer-to-peer mode, two or more SDs can form a network without the need
for any fixed infrastructure.
1.5.1.2 Wireless Routers (WRs)
The Wireless Router (WR) is a low-cost small-sized wireless device
that is primarily deployed to seed a geographical area, extending
the range between IAPs and subscribers, and to simultaneously
increase the network’s spectral efficiency. Wireless Routers provide
a number of functions in the network, such as:
• Range extension for Subscriber Devices and IAPs
• Hopping points for subscriber peer-to-peer networking
• Automatic load balancing
• Route selection
• Network capacity optimization through small packet consolidation
• Fixed reference for geo-location services
The Wireless Router's small size and light weight allow it to be mounted almost anywhere. No
towers are required.

1.5.1.3 Intelligent Acicess Po nts (IAPs)
The Intelligent Access Point (IAP) is a low-cost shoebox-sized
device that acts as the transition point from the wireless network
to the wired core network and from there, through media
gateways, out to the Internet. Each IAP offers up to 6 Mbps burst
of data capacity to subscribers. IAPs support the 10/100 base-T
Ethernet interface. Other interfaces are supported through
commercially available media translation devices. If additional
network capacity is required, more IAPs can be easily deployed without the need for extensive RF or site planning. The location
of an IAP is non-critical due to the self-forming, self-balancing
nature of MeshNetworks’ technology. IAPs provide functions
such as:
• Local mobility management of SDs
• Fixed reference for geo-location services
• Hopping points for subscriber peer-to-peer networking
• Transition point from the wireless to the wired portions of the network
• Route selection
The IAP’s small size and light weight allow it to be mounted anywhere power and network
connectivity are available. No towers are required. IAP software can be updated via over-thewire downloads.
1.5.1.4 Mobile Internet Switching Controller (MiSC)
The Mobile Internet Switching Controller (MiSC) provides
connectivity between the IAPs and wired world, and hosts the
network’s management and provisioning functions. The MiSC is
composed of off-the-shelf hardware components, such as LAN
routers and application servers. MiSC software consists of both
off-the-shelf and MeshNetworks’ proprietary software,
MeshManager. The MeshManager software provides functions for
the network such as:
• Subscriber provisioning, management, and authentication
• Configuration and fault management
• Network monitoring and reporting
1.6 Operational View of the System
Figure 2 shows the different ways in which a subscriber can reach an IAP. It can connect
directly, or hop through any number or combination of WRs and SDs. Additionally, if the
subscriber wishes to execute a peer-to-peer application such as a file transfer, the subscriber
can communicate directly, or through any combination of SDs, WRs, and IAPs.
The ability to use ad hoc routing to forward traffic improves the scalability of the mobile wireless
Internet. In particular, the ability for the user to accomplish a peer-to-peer application without
the use of infrastructure has tremendous advantages. A significant problem in every mobile
wireless network is backhaul. The
architecture provides the ability to route traffic from
4
Setup and Deployment Guide
applications through SDs and WRs without ever reaching an IAP or the wired Internet. This
reduces the amount of backhaul required by enabling the SDs to accomplish the backhaul
whenever the opportunity arises. This results in lower deployment costs, reduced backhaul,
and lower operating expenditures. The service provider can provide the same level of service
with less equipment by empowering the SDs with ad hoc networking capability.
