2 Introduction – System Overview
In a typical telephony and messaging system, the network setup is the interconnection between Base-
stations, routers, repeaters, portable parts, etc. The back-bone of the network depends on the deployment
scenario but a typical Ethernet network is used. The system has centralized monitoring and maintenance.
The system is easy to scale up and supports from 1 to 256 (512) bases in the same network. Further is it
able to support up to 1000 registered handsets. The SMART System setup is illustrated below. Based on PoE
interface each base station is easy to install without additional wires other than the from the LAN cable.
The following figure gives a graphical overview of the architecture of the SMART System:
2.1 Hardware Setup
SMART network hardware setup can deployed as follows:
Base-station(s) are connected via Layer 3 and/or VLAN Aware Router depending on the deployment
requirements. The Layer 3 router implements the switching function.
The base-stations are typically mounted on walls so that each base-station is separated from each other by
up to 50m indoor
1
(300m outdoor). Radio coverage can be extended using repeaters that are installed with
same distance to base-station(s).
The base-station antenna mechanism is based on space diversity feature which improves coverage. The
base-stations uses complete DECT MAC protocol layer and IP media stream audio encoding feature to
provide up to 10 simultaneous calls.
2.2 Components of SMART System
COBS SMART System is made up of (but not limited to) the following components:
•At least one SMART Base Station is connected over an IP network and using DECT as air-core interface.
•COBS SMART1 wireless Handset.
•A WiFi access point
1
Measured with European DECT radio and depends on local building layout and material

7 T100361E_RD_COBS SMART System Guide
•COBS SMART Configuration Interface; is a management interface for SME VoIP Wireless Solution. It
runs on all SMART AP base stations. Each Base station has its own unique settings.
2.2.1 COBS Base Stations
The Base Station converts IP protocol to DECT protocol and transmits the traffic to and from the end-nodes
(i.e. wireless handsets) over a channel. It has 12 available channels.
In a multi-cell setup, each base station has:
•8 channels have associated DSP resources for media streams.
•The remaining 4 channels are reserved for control signalling between IP Base Stations and the SIP/DECT
end nodes (or phones).
Base Stations are grouped into clusters. Within each Cluster, Base Stations are synchronized to enable a
seamless handover when a user moves from one base station coverage to another. For synchronization
purposes, it is not necessary for Base Stations to communicate directly with each other in the system. E.g. a
Base Station may only need to communicate with the next in the chain. It is advisable for a Base Station to
identify more than one Base Station to guarantee synchronization in the situation that one of the Base
Stations fails.
The 4 control signalling channels are used to carry bearer signals that enable a handset to initiate a
handover process.
2.2.2 SMART System Administration interface
The SMART System Configuration Interface is a web based administration page used for configuration and
programming of the base station and relevant network end-nodes. E.g. handsets can be registered or de-
registered from the system using this interface.
The configuration interface can be used as a setup tool for software or firmware download to base stations
and handsets. Further, it is used to check relevant system logs that can be useful to administrator. These
logs can be used to troubleshoot the system when the system faces unforeseen operational issues.
2.2.3 COBS Wireless Handset
The handset SMART1 is an Android based, lightweight, ergonomically and portable unit compatible with
Wideband Audio (G.722), DECT, GAP standard, CAT-iQ audio compliant.
The handset includes touch display with graphical user interface. It can also provide the subscriber with
most of the features available for a wired phone, in addition to its roaming and handover capabilities. Refer
to the relevant handset manuals for full details handset features.
2.3 Wireless Bands
The bands supported in the SMART System are summarized as follows:
Frequency bands: 1880 –1930 MHz (DECT)
1880 –1900 MHz (10 frequencies) Europe/ETSI
1910 –1930 MHz (10 frequencies) LATAM
1920 –1930 MHz (5 carriers) US
2.4 System Capacity (in Summary)

2.5 Advantages of SMART System
They include (but not limited to):
1. Simplicity. Integrating functionalities leads to reduced maintenance and troubleshooting, and significant
cost reductions.
2. Flexibility. Single network architecture can be employed and managed. Furthermore, the architecture is
amenable to different deployment scenarios, including Isolated buildings for in-building coverage, location
with co-located partners, and large to medium scale enterprises deployment for wide coverage.
3. Scalability. SMART network architecture can easily be scaled to the required size depending on customer
requirement.
4. Performance. The integration of different network functionalities leads to the collapse of the protocol
stack in a single network element and thereby eliminates transmission delays between network elements
and reduces the call setup time and packet fragmentation and aggregation delays.

3 Installation of SMART AP
After planning the network, next is to determine the proper places or location the relevant base stations
will be installed. Therefore, we briefly describe the how to install the base station in this chapter.
3.1 Package –Contents/Damage Inspection
Before Package Is Opened:
Examine the shipping package for evidence of physical damage or mishandling prior to opening. If there is a
proof of mishandling prior to opening, you must report it to the relevant support centre of the regional
representative or operator.
Contents of Package:
Make sure all relevant components are available in the package before proceeding to the next step.
Every shipped base unit package/box contains the following items:
2 x mounting screws and 2 x Anchors
1 x Plastic mounting fixture
SMART AP (Base station)
Damage Inspection:
The following are the recommended procedure for you to use for inspection:
1. Examine all relevant components for damage.
2. Make a “defective on arrival – DOA” report or RMA to the operator. Do not move the shipping
carton until it has been examined by the operator. If possible send pictures of the damage. The
operator/regional representative will initiate the necessary procedure to process this RMA. They
will guide the network administrator on how to return the damaged package if necessary.
3. If no damage is found then unwrap all the components and dispose of empty package/carton(s) in
accordance with country specific environmental regulations.
3.2 SMART AP Mechanics
The base station front end shows an LED indicator that signals different functional states of the base unit
and occasionally of the overall network. The indicator is off when the base unit is not powered.

3.3 SMART AP Base Unit –Reset feature
It is possible to restart or reset the base station unit by pressing a “hidden” reset button on the bottom part
of the SMART AP. Alternatively, it can be reset from the SMART System Configuration Interface.
3.4 Installing the SMART AP (Base Station)
First determine the best location that will provide an optimal coverage taking account the construction of
the building, architecture and choice of building materials.
Next, mount the Base Station on a wall to cover range between 50 –300 meters (i.e. 164 to 984 feet),
depending whether it’s an indoor or outdoor installation.
3.4.1 Mounting the Base Stations
We recommend the base station be mounted an angle other than vertical on both concrete/wood/plaster
pillars and walls for optimal radio coverage. Avoid mounting the base units upside down as it significantly
reduces radio coverage.
Mount the base unit as high as possible to clear all nearby objects (e.g. office cubicles and cabinets, etc.).
Avoid all contacts with any high voltage lines.
