TECHNICAL FIELD

The present disclosure relates to signal boosters, and more specifically, to a system and method of switching between one or more antenna for augmenting cellular coverage inside a train.

BACKGROUND

Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information
provided herein is prior art or relevant to the presently claimed invention, or that any
publication specifically or implicitly referenced is prior art.
[0003] Current cellular system implementations involve the use of a few to the use of
many cells to cover a given geographical area. The cells are designed to provide some degree
of overlapping coverage. They are also designed to allow reuse of the same channels several
cells away (but within the same geographical area).
[0004] In practice, cellular system cell-site designs do not cover all the desired
coverage areas due to anomalies of RF propagation. For example, a narrow depression in the
terrain such as a ravine or along a road adjacent to a river bed may not have adequate signal
coverage due to blockage from nearby terrain.
[0005] Another example would be in an underground parking garage or even in large
office buildings where larger than normal signal attenuation would result in unacceptable
signal levels. Furthermore, cell sites in some cellular systems are not located close enough
together, thus resulting in poor coverage areas between the cells.
[0006] Theoretically, a mobile tower may have range up to 30 - 60 Kms depending on
technology and network. But real life maximum range is around 15 Kms in urban multi tower
scenario and 10 Kms in rural single tower landscape. This range is linear. Therefore a dead
zone will be there, where signal from none of the towers reach, hence no mobile signal.
[0007] When a user travel from one cell to another then hand-off or hand-over process
happens. Hand - off means the user call is transferred from one cell tower to another. In other

words carrier gets changed. During transferring call from one cell to another your call may get dropped which was major problem since 5-6 years. If the user enters into dead zone present between two cells you will lose the user network completely. When the user travel from one cell to another then hand-off or hand-over process happens. As trains are running at an average speed of 60 Kmph due to this the user comes across many hand-off processes and dead zones. This is the reason why the user will have very little or no signal while travelling in train.
[0008] The addition of new cell sites to remedy such problems is prohibitive in many
cases. This is because the numbers of subscribers in these areas are generally of insufficient quantity to justify the cost of a new cell site installation. However, there is no a system and method exists that enables switching between one or more antenna for augmenting cellular coverage inside a train. Further, there is no a system and method exists that automatically detects and boosts any cellular network.
[0009] Therefore, there exists a need of an efficient, effective or improved system and
method that enables switching between one or more antenna for augmenting cellular coverage for providing continuous cellular signals to the nearby mobile devices even if such devices are in dead zone. Further, there is a need of system and method exists that automatically detects and boosts any cellular network.

[0047] Problems to be solved in the present invention are that: However, conventional
the addition of new cell sites to remedy such problems is prohibitive in many cases. This is because the numbers of subscribers in these areas are generally of insufficient quantity to justify the cost of a new cell site installation. However, there is no a system and method exists that enables switching between one or more antenna for augmenting cellular coverage inside a train. Further, there is no a system and method exists that automatically detects and boosts any cellular network.
[0048] Therefore, there is a need of efficient, effective or an improved system and
method exists that enables switching between one or more antenna for augmenting cellular coverage for providing continuous cellular signals to the nearby mobile devices even if such devices are in dead zone. Further, there is a need of system and method exists that automatically detects and boosts any cellular network.

[0049] Aspects of the present disclosure relate to a system of switching between one
or more antenna for augmenting cellular coverage inside a train. The system can include a
microcontroller, at least two signal/network booster antenna, one or more switches, and a
wireless module.
[0050] An aspect of the present invention provides a system, device and method that
enable switching between one or more antenna for augmenting cellular coverage for
providing continuous cellular signals to the nearby mobile devices even if such devices are in
dead zone. Further, the system, device and method automatically detect and boost any cellular
network.
[0051] In an aspect, the antenna can be installed in a first and a last compartment of a
train to achieve better signal coverage throughout the train when the train passes dead zones.
The antenna can be installed in any compartment of the train according to need.
[0052] In an aspect, when the first compartment of the train enters a dead zone the
microcontroller detects that the front portion of the train has low/zero cellular coverage.
[0053] In an aspect, the wireless module, with the help of switches can assists in
switching the networks i.e. starts providing cellular coverage from the network as present in
the last compartment. When the first compartment goes into a good signal coverage zone, the
network can be switched back.
[0054] In an exemplary embodiment, in the proposed system a network booster
antenna can be installed at first and last compartment. The antenna can be installed in any
compartment of train according to need for better network strength, along with the booster
installing a local wireless module which can be controlled by a microcontroller.
[0055] In an exemplary embodiment, the proposed system can be smart and automatic
to detect and boost any cellular network. In the proposed system, if there can be small range
of BTS network at the starting point or end point of train, then device can extend and
propagate the network throughout the area.
[0056] FIG. 1 illustrates exemplary dead zone of two antennas, in accordance with an
exemplary embodiment of the present disclosure. FIG. 2 illustrates an exemplary overall
block diagram of the proposed system to elaborate its working, in accordance with an
exemplary embodiment of the present disclosure.

[0057] FIG. 1 shows two cellular signal 1 and signal 2 with a dead zone between
them. When a train passes through these network areas having proposed system, then following events can occur:-
• S-l When first compartment of train is in dead zone of signal 1, then the microcontroller can detect that front portion of the train having no network through wireless module, hence it will boost the network using the signal booster antenna and switch from the last compartment throughout the train.
• S-2 When first compartment is in the region of signal 2, then microcontroller can detect that front portion of the train having a new network (signal 2) through wireless module, hence it will boost the network using Signal booster antenna and switch from the first compartment throughout the train.
Note: Consider 0 as signal not available and 1 as signal available. Signal li and lj is the network which comes under the range of front compartment of the train.
Signal 2i and 2j is the network which comes under the range of last compartment of the train.

Signal li Signal lj Signal 2i Signal 2j Yes/NO Signal boosted
0 1 0 0 Y Signal lj
0 1 0 1 N -
0 1 1 0 Y Signal 2i,lj
0 1 1 1 Y Signal 2i
0 0 0 Y Signal li
0 0 1 Y Signal 2i,2j
0 1 0 N -
0 1 1 Y Signal 2j
1 0 0 Y Signal 2i,2j
1 0 1 Y Signal lj
1 1 0 Y Signal 2i
1 1 1 No need -
Hence most the network problem of dead zone solution can be solved through the proposed device.

208-1 and the last compartments 208-2 of a train (can be installed in any compartment of the
train according to need) to achieve better signal coverage throughout the train when the train

[0061] In another embodiment, the switch 204 switches network coverage of an area
served by a first network to a second network with better signal strength. In another
embodiment, the booster antenna can provide network coverage from the second network.
[0062] In another exemplary embodiment, the booster can include a directional
transmit and receive antenna which is used to transmit signals to and receive signals from the
cell site or network.
[0063] In another embodiment, the booster includes a plurality of intermediate
frequency communication paths such as channel paths 22-30 which provide for transmission
of five channels of control or audio in parallel between one or more networks.
[0064] In another embodiment, the booster can be in communication with the wireless
device or the wireless module 206. The signal booster can be referred to as a repeater. A
repeater can be an electronic device used to amplify (or boost) signals. The booster (also
referred to as a cellular signal amplifier) can improve the quality of wireless communication
by amplifying, filtering, and/or applying other processing techniques via a signal amplifier to
uplink signals communicated from the wireless module 206 to the required network (first
network or second network) and/or downlink signals communicated from the base station to
the wireless module 206. In other words, the booster can amplify or boost uplink signals
and/or downlink signals bi-directionally.
[0065] In another embodiment, the booster can include one or more uplink signal
paths for selected bands, and the booster can include one or more downlink signal paths for
selected bands. The uplink signal paths can include one or more amplifiers and band pass
filters to amplify uplink signals. Similarly, the downlink signal paths can include one or more
amplifiers and band pass filters to amplify downlink signals.

[0066] In another embodiment, the wireless module 206 may include a
processor which controls operation of the wireless module 206. The processor may also be
referred to as a central processing unit (CPU). Memory, which may include both read-only
memory (ROM) and random access memory (RAM), provides instructions and data to the
processor. A portion of the memory may also include non-volatile random access memory
(NVRAM). The processor typically performs logical and arithmetic operations based on
program instructions stored within the memory. The instructions in the memory may be
executable to implement the methods described herein.
