Indoor range
The maximum range of the phone indoors. Walls act as a rather serious obstacle to radio waves, so the range of a phone indoors is usually much less than in open areas. Usually, the specs indicate the maximum range for a classic office space with medium-sized rooms. In fact, the range depends on many factors (thickness, material and number of walls, floor difference, the presence of interference-producing electronic equipment, etc.) and often turns out to be less than theoretical.
Outdoor range
Handset range outdoors. Usually, the specs indicate the range in line-of-sight conditions, that is, with the complete absence of obstacles between the handset and the base; thus, the outdoor range may be less than claimed due to the presence of obstacles (houses, trees, etc.).
Standby time
The maximum operating time of the handset on one full battery charge, without contact with the base, in standby mode, that is, when no actions are taken with the handset. Note that at the end of the maximum time in standby mode, the battery charge may be so small that when a call arrives, the handset may simply not be able to support it for any long time. Therefore, without a serious need, you should not keep the handset out of the base for long, and it is better to return it for recharge in advance.
Talk Time
The maximum time of operation of the handset on one full charge of the battery in talk mode. Long talk time will be relevant for those who expect to regularly conduct long telephone conversations.
Wall mount
Possibility of mounting the base of the radiotelephone
on the wall. The advantage of this mount is that the phone does not require a horizontal surface for installation. This allows you to both save space on the desktop, shelf, etc., and install the phone where it would be difficult to provide a horizontal surface — for example, in the hallway.
