Au inceput sa se adune echipamentele tetra pe masa mea de lucru si implicit studiul sistemului.Cautand informatii am dat peste o comparatie intre terminalele Hytera si Motorola Tetra. Nu stiu cine a facut studiul asa ca eu vreau sa ma conving singur 🙂

•No RFID Knobs
•No integrated Bluetooth 4.0/2.1 with EDR
•No Fast Wireless PTT
•No Wideband Operation (350-470 Mhz)
•No High Reflectivity Glass Display
•No WAP 2.0 with WAP Push
•No Indoor Location Capability
•No Wireless Applications via EDR
•No Energy/Economy Mode
•No SDS Store/Forward for Group Messages
•No Authentication with TEI query
•No SDS over Packet Data Channel
•No Class 3G error encryption
•No Secure DMO
•No Radio User Identification (RUI)
•No Call Out Feature
•No Limited Keypad form factor
•No Class 2 (SCK) OTAR Capability
•No Class 3G (GCK) Capability
MTP3000 Series Top Advantages:
•Audio – MTP3000 features louder, clearer and more intelligible audio due to its 2W speaker with up to 4W peak power and adaptive audio control.
•Ergonomics – Smaller, lighter mechanical design (MTP is 273g v. 294g for the PT-580H), larger and more ergonomic PTT, High Reflectivity Glass Display for clearer outside operation, Self-cleaning bottom connector, and side connector featuring one hand connect/disconnect.
•SW Functionality – SW applications and services suite including Call Out, SDS, WAP Push, Smart Phone Control, and Indoor Location
•Data Efficiency – SDS over control channel or packet data channel, Up to 60 users per channel, Priority Data Messages
MTP3000 Series features Integrated Bluetooth 4.0 which allows for more flexibility and ease of use.
•MTP3000 Series features WAP 2.0 with WAP Push to allow pictures to be pushed onto terminals.
•MTP3000 Series supports location services including GPS, GLONASS and Beidou.
•MTP3000 Series side connector supports a wider range of available accessories (4 RSM’s, 6 earpieces, 2 headsets, desktop and multi-unit chargers w/ ITM functionality) with comparable performance with the radio internal speaker.
•Since the PT-580H lacks a bottom connector it cannot be programmed or sent control commands via the PEI port while in a charger unless a cable is hooked to each individual radio. The MTP3000 Series bottom connector and networked chargers allow for gang radio configuration and programming changes to be made while docked for charging.
