2.3 Wireless Bands
The bands supported in the SME VoIP are summarized as follows:
Frequency bands:
1880 – 1930 MHz (DECT)
1880 – 1900 MHz (10 carriers) Europe/ETSI
1910 – 1930 MHz (10 carriers) LATAM
1920 – 1930 MHz (5 carriers) US
2.4 System Capacity (in Summary)
SME network capacity of relevant components can be summarized as follows:
DESCRIPTION CAPACITY
Min ## of Bases Single Cell Setup 1
Max ## of Bases in Multi-cell Setup (configurable) 50/127/254
Single/Multi Cell Setup: Max ## of Repeaters 50 bases and 3 repeaters per Base
127 bases and 1 repeater per Base
254 bases and 0 repeaters
Multi-cell Setup: Total Max ## of Repeaters 100
Max ## of Users (SIP registrations) per Base
30
Max ## of Users per SME VoIP System limited to 1000
Multi-cell Setup: Max ## of Synchronization levels 24
Single Cell Setup: Max ## Simultaneous Calls
10
*
per
Base station
Multi-cell Setup: Max ## of Calls 8* per Base station
Total Max ## Simultaneous Calls (Multi-cell Setup) Limited to 1000
Repeater: Max ## of Calls (Narrow band)
5
Repeater: Max ## of Calls (G722) 2
* If G722 is in the codec list, it will reserve audio resources to be able to handle the possible G722 call. This means,
that the maximum number of possible narrowband calls is reduced by one extra.
Single Cell Setup: SME telephony network composed of one Base station
Multi-cell Setup: Telephony network that consists of more than one Base station
Synchronization Level: Is the air core interface between two Base stations.
NOTE: Please note that if there are over 150 base stations in a multicell, the “Multicast” data sync should be use
2.5 Advantages of SME VoIP 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. SME 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.
