• Speech Quality / Clarity– TETRA uses HSX VOCODER, developed in 90’s.
– Poor naturalistic voice

* Based on Kenwood’s simulation
• Coverage– Communication distance*
• TETRA : Mobile@8km/h, Suburb, 10W 11km• TETRA : Portable@8km/h, Suburb, 1W 5.7km
Less than half of UHF NEXEDGETM’s Communication coverage Almost 1/4 of VHF NEXEDGETM’s Communication coverage
• Number of Base stations*– 4-6 (16-18) sites needed for equivalent 1 site NEXEDGETM coverage
for UHF (VHF)

• Trunking Repeater– Need Optional UC-FR5000 for Single-Site Trunking & IP
network connection (IP base recently released)
– Mobile like hardware as analog
– No built-in Digital Trunking Controller
– 2 RF/Ch option is available (see top left picture)
ICOM Digital
FR5000/6000 Repeater
Mobile like repeater has lighter duty cycle as compared to a base station with big heat-sink design. The impact is more significant when 2 RF is packed into one. This may be suitable for light duty application but not heavy or long term usage.When use as a Control Channel, it may stress the transmitter and hence its life-cycle.

What is NXDNTM?
NXDNTM
(Air interface, FDMA, 6.25kHz)Supporting Basic Features ( voice call, etc.)
• To avoid monopoly Kenwood, Icom and many more companies has sign MOU and
agreed to promote NXDNTM CAI (Common Air Interface) for the benefit of end-user.

FDMA and TDMA
• TDMA (Time Division Multiple Access)– Pros
• Better power consumption than FDMA (Theoretically)• Full duplex capability
Time
Time Slot
– Cons• Limited Communication distanceLimited Communication distance due to the Guard Time
(up to 35km approx. for TETRA, up to 150km approx. for DMR)• Repeater required (Multi-slot not available in Direct Mode)• Not a true physical 6.25kHz technology Not a true physical 6.25kHz technology (6.25kHz equivalent)• Linear external AMP required for TETRATETRA

FDMA and TDMA
• FDMA (Frequency Division Multiple Access)– Pros
• Direct mode communication between 2 parties is possible.• Pure very narrow technology resolving Freq. resource issue• Majority existing equipments can be reused (No linear AMP
required)• Less sites are needed for same amount of coverage.
