MikroTik wAP LR2 Kit LoRa 2.4GHz IoT Gateway IP54

The MikroTik wAP LR2 kit is MikroTik's second-generation outdoor LoRa gateway — and the most significant departure from the standard LoRaWAN architecture in the current MikroTik LoRa product line. Where the wAP LR8 kit operates on 863–870 MHz or 902–928 MHz (sub-GHz LoRaWAN bands), the wAP LR2 kit's R11e-LR2 modem card operates on the 2.4 GHz band for LoRa — a fundamentally different operating point with meaningfully different performance characteristics that make it the correct choice for specific IoT deployment scenarios.

**2.4 GHz LoRa — what changes versus sub-GHz LoRaWAN**

LoRa (Long Range) is a Chirp Spread Spectrum (CSS) physical layer modulation technique. The CSS modulation is what gives LoRa its long-range capability, deep building penetration, and interference resistance — and importantly, CSS modulation on 2.4 GHz does not interfere with 802.11b/g/n/ax WLAN signals on the same 2.4 GHz band. The Chirp modulation sweeps across the spread bandwidth in a pattern that 802.11 Wi-Fi radios cannot demodulate and treat as noise well below their interference threshold — the wAP LR2 kit's LoRa radio and its 802.11b/g/n WLAN radio coexist on 2.4 GHz without mutual interference. MikroTik explicitly confirms this on the product page: "it doesn't interfere with the 2.4 GHz WLAN signal."

The shift from sub-GHz to 2.4 GHz changes three key operational parameters:

- **Higher bandwidth and data rate:** 2.4 GHz LoRa supports significantly higher bandwidth than sub-GHz LoRaWAN channels. Sub-GHz LoRaWAN channels are 125 kHz, 250 kHz, or 500 kHz wide with data rates of 0.3–50 kbps depending on spreading factor and bandwidth. 2.4 GHz LoRa operates at higher bandwidth settings that support data rates up to 200 kbps+ — an order of magnitude above sub-GHz LoRaWAN's practical throughput ceiling for uplink-heavy sensor networks. For IoT applications that need to transmit more than just a few bytes per sensor per hour — firmware OTA updates, camera image thumbnails, higher-frequency sensor readings, or multi-sensor aggregation payloads — 2.4 GHz LoRa's higher data rate makes the application feasible where sub-GHz LoRaWAN would be too slow.

- **Lower air time:** Air time — the duration a LoRa channel is occupied by a single packet transmission — is inversely proportional to data rate. Higher data rate means shorter air time per packet. In a high-density sensor deployment where hundreds of sensors are transmitting to a single gateway, air time contention is the primary capacity constraint: if each sensor's packet occupies the channel for 1–2 seconds at sub-GHz LoRaWAN data rates, a gateway serving 500 sensors hits channel capacity quickly. 2.4 GHz LoRa's lower air time per packet dramatically increases the number of sensors a single gateway can serve simultaneously — MikroTik's own positioning statement calls it "a perfect solution for industrial setups with a high density of sensors."

- **Shorter range trade-off:** 2.4 GHz propagation attenuates faster with distance than sub-GHz frequencies. The free-space path loss at 2.4 GHz is approximately 9 dB higher than at 868 MHz at the same distance — meaning the 2.4 GHz LoRa gateway covers a meaningfully smaller geographic footprint than a sub-GHz LoRaWAN gateway at equivalent transmit power and antenna gain. For wide-area rural coverage deployments where a single gateway must cover kilometres of farmland, the sub-GHz wAP LR8 kit is the correct choice. For dense industrial, warehouse, campus, or urban sensor deployments where sensors are within 1–2 km of the gateway and high sensor density is the operational constraint, 2.4 GHz LoRa's higher capacity and lower air time outweigh the reduced range.

**The R11e-LR2 miniPCIe LoRa card**

The R11e-LR2 is MikroTik's miniPCIe 2.4 GHz LoRa radio card — installed in the wAP LR2 kit's single miniPCIe slot and connected to the 4.7 dBi built-in LoRa antenna. The R11e-LR2 is the hardware component that provides the 2.4 GHz Chirp Spread Spectrum radio capability. The miniPCIe form factor means the R11e-LR2 can also be installed in other MikroTik RouterBOARD devices with a miniPCIe slot — providing 2.4 GHz LoRa capability to a wider range of MikroTik hardware platforms beyond the wAP enclosure.

The 4.7 dBi built-in LoRa antenna is significantly higher gain than the 2 dBi built-in WLAN antenna — reflecting the directional sensitivity priorities of the two radios. The LoRa gateway antenna receives uplink transmissions from potentially hundreds of dispersed sensors — higher antenna gain improves link budget and extends the effective sensor coverage radius. For deployments requiring even greater sensor coverage radius, MikroTik recommends the TOF-2400-8V-4 external omni antenna (sold separately), which connects to the wAP LR2 kit's external antenna connector and replaces the built-in LoRa antenna with 8 dBi omnidirectional gain — adding approximately 3.3 dB of additional link budget over the built-in 4.7 dBi antenna.

**Pre-installed UDP packet forwarder — zero-configuration LoRa server integration**

The wAP LR2 kit ships with a pre-installed UDP packet forwarder — the standard LoRaWAN packet forwarder protocol that connects a LoRa gateway to a Network Server. The UDP packet forwarder is the protocol bridge between the LoRa radio layer (the R11e-LR2 card receiving sensor uplink packets) and the LoRa Network Server (The Things Network, ChirpStack, Actility, Loriot, or a private LoRa server). Configuration requires only specifying the Network Server's IP address or hostname and the appropriate UDP port in the packet forwarder configuration — the wAP LR2 kit then forwards all received LoRa sensor packets to that server in real time.

For a deployment using The Things Network (TTN) or The Things Stack (TTS) as the LoRa Network Server — the most common public LoRa infrastructure — the wAP LR2 kit's UDP packet forwarder connects to TTN's gateway server endpoint with minimal configuration. TTN/TTS provides the Network Server, Application Server, and Join Server layers for LoRaWAN protocol handling, leaving the wAP LR2 kit's role as purely a radio packet forwarder. For organisations running a private LoRa server — ChirpStack on a private cloud VM, or a local ChirpStack instance on a MikroTik CHR router — the UDP packet forwarder configuration points to the private server instead.

**2.4 GHz Wi-Fi 4 backend — network uplink and local management**

The QCA9531's built-in 2.4 GHz 802.11b/g/n radio with 2 dBi built-in WLAN antenna serves as the wAP LR2 kit's network backend and local management interface. In the wAP LR2 kit architecture, the Wi-Fi radio connects the gateway to the upstream network — a local Wi-Fi network that provides internet access for the UDP packet forwarder's connection to the LoRa Network Server. The Wi-Fi radio can also operate as a Wi-Fi access point for local management access via the MikroTik smartphone app or a laptop browser.

For deployments where a wired Ethernet backhaul is available, the single 10/100 Ethernet port with passive PoE-in (9–30V) is the preferred uplink — wired Ethernet provides lower latency and higher reliability than Wi-Fi for the packet forwarder's upstream connection. For deployments without wired infrastructure — a warehouse column, a building exterior, a rooftop equipment mount, or an agricultural field installation — the Wi-Fi radio connects to an existing Wi-Fi network as a client, providing the upstream internet path for the packet forwarder without Ethernet cabling to the gateway location.

**Automotive input — vehicle and mobile IoT deployments**

The automotive 9–30V DC input is the third power option alongside the DC jack (9–30V) and passive PoE-in (9–30V). The automotive input accepts the full 9–30V vehicle DC voltage range — 12V passenger vehicles, 24V commercial vehicles and heavy equipment — with protection appropriate for vehicle electrical environments. Combined with the IP54 weatherproofing and -40°C to +60°C operating temperature, the automotive power input makes the wAP LR2 kit deployable on vehicles — a mobile 2.4 GHz LoRa gateway mounted on a farm vehicle, a service truck, or a public transit bus, collecting sensor data from distributed IoT devices as the vehicle moves through the deployment area. The SIM slot note is important for vehicle deployments: the Mini SIM slot on the wAP LR2 kit is intended for LTE modem use only — and only when the R11e-LR2 LoRa card is removed and replaced with an LTE miniPCIe modem. The wAP LR2 kit as shipped has the SIM slot occupied by the LoRa card and provides no cellular data capability without hardware modification.

**Mini SIM slot — LTE upgrade path (modem swap required)**

MikroTik explicitly notes on the product page: "the device has no built-in LTE modem, the SIM slot can only be used if LoRa interface card is removed and replaced by an LTE modem." This is an important advisory for customers who might assume the SIM slot provides cellular connectivity alongside the LoRa radio. As shipped, the miniPCIe slot is occupied by the R11e-LR2 LoRa card — removing it and installing a compatible LTE miniPCIe modem (such as the R11e-LTE7) converts the wAP LR2 kit into an LTE router using the wAP enclosure, but removes the LoRa capability entirely. The two functions are mutually exclusive in the same hardware.

For deployments where both LoRa gateway functionality and cellular WAN connectivity are required simultaneously, the correct MikroTik solution is the CME Gateway (CME22-2n-BG77) — which provides built-in CAT-M cellular and Ethernet connectivity as the upstream backhaul for a separately deployed LoRa gateway.

**External antenna upgrade — TOF-2400-8V-4**

MikroTik specifically recommends the TOF-2400-8V-4 omni antenna (sold separately) for deployments requiring extended LoRa sensor coverage radius. The TOF-2400-8V-4 is an 8 dBi omnidirectional fiberglass antenna for the 2.4 GHz band — connecting to the wAP LR2 kit's external LoRa antenna connector and replacing the built-in 4.7 dBi antenna. For a dense warehouse or campus deployment where sensor nodes are distributed throughout a large building or across multiple buildings within a campus, the 8 dBi external omni antenna extends the reliable uplink range from sensor nodes at the extremities of the deployment area. Cross-list the TOF-2400-8V-4 as a recommended accessory on the wAP LR2 kit product page.

**5-year software support guarantee:** RouterOS v7 updates free for life of product or minimum 5 years from date of purchase.

**Canadian market note — IC certification confirmed:** The wAP LR2 kit is certified CE, FCC, IC, EAC, and RoHS — IC (ISED) certification is confirmed and published on the product page. The wAP LR2 kit can be listed and sold for Canadian wireless operation without an IC certification advisory. Note that the 2.4 GHz LoRa radio operates under the unlicensed 2.4 GHz ISM band rules (RSS-210 / RSS-247 in Canada) — the CSS modulation does not require a separate LoRa-specific licence in Canada. Confirm the specific IC certification number from the regulatory documentation for listing purposes.
