Why is a WWAN modem embedded in a laptop a better choice than a PC Air Card?
A few of the advantages of Toughbook’s embedded modem: • Heat build up generated from PC Air Cards and poorly located WWAN modems in a laptop could lead to software instability. Therefore the WWAN modem in a Toughbook is physically located away from the motherboard. This ensures that any heat generated from the modem is not compounded by the heat from the motherboard. • The modem itself is only operational when you are connected to the wireless carrier’s network, otherwise the modem can be turned off, conserving the battery. PC Air Cards are “hot” as long as they are inserted. • Because the antenna is internalized in the laptop the overall reception is superior to a PC Air Card. This also ensures that the antenna cannot get lost. • The warranty of the embedded modem lasts just as long as the Toughbook—3 years. A PC Air Card warranty is typically 90 days to 1 year.
