Lantiq and Intel have added a new LTE module option enabling manufacturers of home gateways to add 4G wireless broadband connectivity in their home routers.
More and more handsets include the option to automatically switch from a cellular connection to a nearby Wi-Fi connection, but the LTE router option has been growing rapidly in emerging telecommunications markets and in some rural markets.
The design uses an Intel module based on the XMM 7260 LTE platform that supports transmission rates up to 300 Mbps. That module is incorporated into Lantiq’s GRX330 communications processor reference design.
Features of the Intel module include flexible carrier aggregation – up to 40MHz with support for up to 23 CA combinations in one SKU – and LTE Cat 6 speeds (300 Mbps theoretical peak downlink speeds).
The 7260 also provides global communications, supporting more than 30 3GPP bands (21 bands simultaneous in a single SKU) and global network standards (LTE FDD/TDD, WCDMA/HSPA+, TD-SCDMA/TD-HSPA/EDGE).
The Lantiq processor, meanwhile, offers a full Gigabit Ethernet router design, using a dedicated acceleration engine to maximize Wi-Fi throughput, while keeping the CPU available for other networking and application tasks
The Lantiq GRX330 reference design supports the following feature set:
- 4x Gigabit Ethernet
- 2.4GHz Wifi 11n or 5GHz Wifi 11ac or 11n (supported by an additional mPCIe module)
- FXS voice, DECT/Cat-iq cordless voice
- Additional Home Networking or Home Automation technologies supported through RGMII.
If desired, the platform can also support DSLTE with the addition of a VDSL frontend, the company said.
Jeff Heynen, principal analyst, Infonetics Research, said, “We are already seeing early shipments of fixed LTE gateways in emerging markets, as well as among rural providers where fixed broadband services are either cost-prohibitive to deploy or regulatory issues prevent local loop unbundling. We expect the market for these devices to continue to grow rapidly as LTE networks get rolled out globally.”
