3. CellMesh network and devices
CellMesh is a wireless self-organizing network consisted of microcells; it carries a very strong
derivative characteristic and has a full-featured mesh structure. CellMesh has diverse
structure, distinctive hierarchy and simple network establishment logic. There is an information
collection center in every cell to form information convergence by utilizing point to multi-point
route and mesh network route. Varies geographic areas can be covered seamlessly according
to the known Cellular coverage principle. The network can either form a wireless mesh
network within a single cell by itself or quickly derivate a network covering a certain area to
form Wide Area Network
CellMesh is consisted of center node named CAC and slave nodes named DAU. CAC starts a
cell network establishment, maintains and manages the network. In a CellMesh network, DAU
node acts as data access point as well as router. DAU is responsible for data collection, and
uploads the data to CAC. Communication distance between CAC and DAU can reach a 2000
meters’ diameter coverage by seven hops relaying, hence to realize 100% collection and full
coverage.
CellMesh network topology:

There are multiple routes to reach destination, when one route is blocked, a second route will
be selected automatically, guaranteeing the net link.
Installing and commissioning are very easy since the networking is automatically
accomplished and optimized. Large-scale network extension and derivative also become
simple.
More than 10 million CellMesh communication nodes have been deployed all around the world,
including remote metering, data monitoring, smart home, security system, oilfield information
collection, streetlight control and so on.
L-CellMesh network
L-CellMesh is derived from our famous CellMesh network with an ultra-low power
management technology to support battery-powered devices.
L-CellMesh advanced power management technology, using synchronous sleep mode and
Energy-budget method that can maximize the battery life of the node.
Communication node works in breathing mode, data communications have a high-speed
wake up, low-speed communication mechanism, which reduces data transmission time while
increase the wake-up speed. After wake-up, using low-speed communication to ensure the
reliability of data transmission , reducing the number of data exchange , to ensure power
saving .
With full network synchronization breathing mechanism, all node are at random status initially.
After network established, CAC will let the whole network timing synchronized. All nodes within
the same network will be in sleep mode at the same time and the same for wake-up mode and
there is a neighbor node compensation algorithm to guarantee it , which make the
communication between node more convenient and timesaving, it also enable the direct
communication without wakening to reduce data transmission and current consumption. In the
communication process, the node also has self-adjusting function, improving the efficiency of
the system.
Effective energy-budget management. In the entire L-CellMesh network, the remaining energy
of each node will be different; CAC central node will analyze all the remaining energy of each
node when calculating the relay path, choose the best path as well as the highest energy path,
avoid using some key LDAU router point excessively. This enables a balance in power
consumption to increase the average lifetime of batteries.
