The Skywire is a small plug-in embedded cellular modem. It uses a standard XBee form factor and 1xRTT CDMA operating mode to help developers minimize hardware and network costs. Its U.FL port ensures antenna flexibility.
The Skywire modem features a Telit CE910-DUAL wireless module and is available with bundled CDMA 1xRTT data plans from leading carriers, enabling developers to add fully compliant cellular connectivity without applying for certification. Future versions of the Skywire will support GSM and LTE. Skywire is smaller than many other embedded solutions and simple to deploy due to its bundled carrier service plans.
Skywire is available with a complete development kit that includes the cellular modem, a baseboard, an antenna, a power supply, debug cables, and a cellular service plan. The Skywire baseboard is an Arduino shield, which enables direct connection to an Arduino microcontroller.
Skywire modems cost $129 individually and $99 for 1,000-unit quantities. A complete development kit including the modem costs $262.
The TOBY-L1 series is u-blox’s latest line of ultra-compact long-term evolution (LTE) modules. The TOBY-L100 and its European version, the TOBY-L110, are suitable for tablets, mobile routers, set-top boxes, and high-speed machine-to-machine (M2M) applications (e.g., digital signage, mobile health, and security systems).
Compared with multi-mode modules, LTE-only modules offer cost advantages. Therefore, the TOBY-L1 works well in networks with advanced LTE deployment applications.
The LTE modules are available in two versions: the TOBY-L100 for the US (bands 4 and 13 for Verizon) and the TOBY-L110 for Europe (bands 3, 7, and 20 for EU operators). Contained in a compact 152-pin LGA module, the TOBY-L1 series is layout-compatible with u-blox’s SARA Global System for Mobile (GSM) and LISA Universal Mobile Telecommunications System/Code Division Multiple Access (UMTS/CDMA) module series to facilitate easy product migration and low-cost regional end-device adaptation.
The TOBY-L1 modules are based on u-blox’s LTE protocol stack. The modules support smooth migration between 2G, 3G, and 4G technologies and feature small packaging and comprehensive support tools. The TOBY-L1 LGA modules measure 2.8 mm × 24.8 mm × 35.6 mm, which enables them to easily mount on any application board.
The modules support USB 2.0 and firmware update over the air (FOTA) technology. The TOBY-L1 series delivers ultra-fast data rates and operates from –40°C to 85°C. USB drivers for Windows XP and 7 plus Radio Interface Layer (RIL) software for Android 4.0 and 4.2 are available free of charge.
