Accessories

The Universal Development Kit (UDK) is a hardware development platform for

AirPrime MC-series modules. It contains hardware components for evaluating

and developing with the module, including:

• Development board

• Cables

• Antennas (Bands 17, 13, and 7 are not supported by supplied antennas)

• Documentation suite

• Initial allotment of support hours

• Other accessories

For instructions on setting up the UDK, see [4] PCI Express Mini Card Dev Kit

Quick Start Guide (Doc# 2130705).

For over-the-air LTE testing, ensure that suitable antennas are used. (Two

antennas are required for this testing; Sierra Wireless offers an LTE-capable

antenna covering 700–2600

MHz BW — please order part number 6000492

(Qty

1 — this contains two antennas).)
