Motorola's LTE Broadband

Tutorial Scripts

Welcome to Motorola's LTE Broadband feature’s Satellite View.

The Long Term Evolution Broadband feature, known as "LTE Broadband", allows Motorola radios to access this high-speed Data Pipeline created by the cellular industry, which is also known as 4G. 4G significantly improves data speeds for data-intensive radio applications.

Traditional Motorola-Radio “Wireless Data Communications” use Land Mobile Radio infrastructure for Data Applications and Services. LTE Broadband is another Wireless Data infrastructure solution for Data Applications and Services. For data intensive applications such as Over-The-Air CPS Programming, this LTE Broadband feature can greatly enhance data capacity and data transfer speeds.

LTE Broadband can also apply for Data Applications and Data Services such as Text Messaging Service (TMS), GPS Location Services, Automatic Registration Service (ARS), and Over-the-Air-Rekeying (OTAR). Note that, Secure Encryption of this LTE Broadband data is accomplished through Virtual Private Network technologies. Also note that, only data communications are possible on the Broadband network, and APCO Voice can continue uninterrupted over the Land Mobile Radio Infrastructure.

Programming LTE Broadband Data Wide Settings

To begin with, the CPS’s Data Wide, General Page, and LTE Page, contain the expert-level features and settings necessary to establish LTE Broadband communications, or to transfer those data communications to a traditional Land Mobile Radio network when the LTE Network is unavailable.

Defining LTE-Capable Data Profiles

From the Data Profiles window, the Data Profile Type field determines Broadband and Non-Broadband in-the-field data pathways.

When either the "Trunking & Broadband" or "Conventional & Broadband" data profile type is selected, the LTE Broadband data network has priority when sending and receiving data; therefore, in these two cases, the radio only uses the traditional Land Mobile Radio network when the Broadband Data network is unavailable. However, when the selected Data Profile Type is "Broadband-Only", the Broadband Data network is the only available pathway for data communications. “Broadband-Only” Data Profiles are selectable for both Conventional and Trunking channels.

Do note that, these three, “Broadband Capable” Data Profile Types, have several Data Profile-common settings. For instance, on the Data Profile's LTE Page, the LTE Enable field ultimately allows for LTE Broadband on a per Data Profile basis.

And, on the Network Layer Security Page, the "VPN Secure/Clear Strapping" field allows for "Secure" data encryption through the use of Virtual Private Networks. With secure encryption enabled, additional "VPN" related fields must then be defined.

Also note that, the Bypass List Page allows you to create a list of IP Addresses that can avoid this secure data encryption.

Ultimately, all Data Profiles are given easily-recognizable Data Profile Names that are used for CPS-selection purposes.

Linking the LTE-Capable Data Profile to a Channel

Once created, the “Broadband Capable” Data Profile is specifically selected for either a Conventional System or for a Trunking System. Once this LTE-enabled Conventional or Trunking System has been defined, a specific Personality is then referenced to this System.

Also, do be aware that, 700 MHz frequencies may create interference with LTE Broadband. Which is why LTE Enabled channels cannot contain 700 MHz frequencies, and an LTE Enabled channel’s Scan List Members also cannot contain any 700 MHz frequencies. Therefore, with LTE Enabled in Trunking, at the Trunking System level, the 700 MHz Frequency Interference feature automatically indicates potential conflicts to the CPS; however, for LTE Enabled channels in Conventional, the 700 MHz Frequency Interference feature is at the Personality level, and in this case it must be manually enabled, which again is indicating potential conflicts to the CPS.

Ultimately, through the Zone Channel Assignment's Channels Page, the Personality is selected for a specific radio channel where LTE Broadband data capabilities are desired.

Programming Radio User LTE Controls

Radio-wide enabling and disabling of LTE Broadband data capabilities may be radio-user initiated by programming an LTE button-press or an LTE menu-selection.
