Available variants
Bytton is a very versatile equipment; it features inside one motherboard that can get several types
of plug-in daughter boards, according to the functions requested by the customer. Because of this, your
actual equipment may not look identical to the pictures presented in the manual, and may not have all the
features described. The main variants / options are:
several types of mobile modules, for 2G or 3G+ networks (UMTS, HSDPA, HSPA+), and even
LTE (assuring up to100 Mbps peak download rate), or for different frequency bands:
850/900/1800/1900 MHz for GSM/GPRS/EDGE, 2100 MHz for HSDPA or HSPA+,
800/900/1800/2100/2600 MHz for LTE and so on. The external aspect of the equipment remains
the same for all variants of modules, but the capabilities (and price!) are different. Some type of
modules feature antenna diversity (MIMO capabilities): connection of two Mobile antennas, for
diversity reception or for achieving higher data rates. Thus, special Bytton equipments may
feature four antenna connectors, two for the MOB mobile data network (HSPA+, LTE) and two for
the embedded Wi-Fi module. GPS capability is also available, for mobile units, powered form the
car battery;
no voice capabilities and no Wi-Fi, with two data SIMs (not concurrently) for higher availability
and with serial interface(s) for legacy devices. It has holders for two data SIMs; the device may be
used with one or two SIM cards. It may feature one serial interface (SER2).
still no voice capabilities but with Wi-Fi for wireless local connection, a single data SIM. The four
Ethernet connectors are present In this case the connector for Wi-Fi antenna is present, located
near the center of the front panel, together with the corresponding indicator LED for Wi-Fi. No
serial interface!
with
voice
capability (one FXS interface located to the left) and also with Wi-Fi, one voice/data
SIM card. The connector for Wi-Fi antenna is present, together with the corresponding LED for
Wi-Fi. Since there are not two mobile modules (it cannot perform LTE for two mobile carriers), the
variants with telephone port always use a single SIM card.
BYT_4G_FC1/ BYT_3G_FC1, the variant with one serial interfaces, labeled “SER”, available for
connections to legacy equipments. No voice capabilities, no Wi-Fi antenna and hence no Wi-Fi
indicator, a single SIM card. The RS-232 interface feature RJ-45 connectors on the front panel.
the Lite (low cost) variant of the equipment, a Topex Bytton LTE with no voice capabilities and no
Wi-Fi, a single data SIM, and no serial interfaces. Out of the four Eth ports, there are two LAN
ports, one configurable WAN0/LAN0 port, and the dedicated WAN port;
There is an even simpler variant, with no SIM and hence mobile data capability, used as an
advanced network router. The front panel features
just four ETH ports, one SER.
Advanced variants with one or two serial interfaces, and one or two SIM cards besides the Mobile
antenna and the four ETH ports. The two serial ports labeled “SER1” and respectively “SER2” are
available for connections to legacy equipments. The RS-232 interfaces feature RJ-45 connectors
on the front panel. The phone line interface (FXS) is missing, but the Wi-Fi access point can be
present, for wireless connection of equipments in the field. The front panel features, from left to
right: the circular antenna connector Mob, two SER connectors, the round Wi-Fi connector for
wireless antenna, the four Ethernet connectors (WAN, WAN0/LAN0, LAN2, and LAN1), the
recessed Reset button and the PWR jack for power supply!
