The
Broom modem has upload speeds of 11.5 Mbps and download speeds of 28Mbps.
Because the LTE and all other HSPA evolution models share the same platform,
the new LTE modem is fully compatible with earlier standards. Through this technology,
a mobile communications service provider can upgrade to HSPA service or evolve
into a LTE network simultaneously in order to convert their existing networks
to broadband. In the future, this flexibility will be crucial as wireless
mobile service providers will require compatibility with pre-existing systems,
in order to offer LTE in urban areas while still supporting 3G in suburban or
rural areas. |
