The ML-CSA 4500 is a plug-and-play 4G/3G/2G cell signal amplifier that boosts uplink and downlink signal strength by up to 15dB for M2M devices like routers, modems, and gateways. It has a patented passive bypass feature that allows the device to remain online even if the amplifier detects a fault or power outage. The amplifier is designed exclusively for direct connect M2M applications in industries like security, utilities and more to ensure real-time monitoring and control.

1. ML-CSA 4500
4G 5-Band M2M Cell Signal Amplifier
The ML-CSA 4500 4G LTE Cell Signal Amplifier is a “Plug & Play” device that connects in-line with any
M2M cell-enabled router, modem, module, or gateway. It enhances downlink and boosts UPLINK cell
signal strength by up to 15dB to lock in data connec ons. Premier Uplink Connec vity
is essen al for M2M devices to connect to the cell tower for real- me monitoring & control.

2. ML-CSA 4500’s Passive Bypass feature allows the amplifier to passively bypass itself and become merely
a “pass-through” cable during these occurrences:
• When amplifica on is not necessary, e.g. exis ng cell signal strength is adequate
• When connected cell device goes into “Stand-By” Mode
• When there is a power loss to amplifier
• When a fault is detected

Passive Bypass technology is useful in applications where the amplifier is mobile, moving in and out of poor
signal areas. The amplifier will bypass itself when in close proximity to cell towers. This serves as a
safeguard feature, completely eliminating any potential for disruption to the cell network. This unique
feature is also extremely useful in fire & security system installations where a connection with the antenna
must always be maintained, even with loss of power.
